Introduction:
Building on the strong foundations of Bruce Engineering and Polly Locos, Polly Model
Engineering Limited is one of the leading suppliers to the model engineering hobby. Unique
amongst suppliers with its in house manufacturing capabilities, Polly is able to address all
your model engineering requirements. Combining over forty years experience in supplying
model engineers and a comparable time in the manufacture of renowned Polly kit build
locomotives, we can justifiably claim to understand the needs of the model engineer.
Furthermore we pride ourselves on the stock held, such that most items are available for
immediate despatch.
Separate catalogues are available detailing: Polly Locomotive kits, Polly Spares and Stuart
Models. This catalogue combines the model engineers supplies and the Practical Scale
elements of our business. Frequently in the recent past we have found customers not
realising that the items required were available from Polly, but in the other catalogue. We
hope you find this catalogue interesting and useful.
The range of products listed is vast and whilst we are proud to be appointed agents by
suppliers such as Loctite and Johnson Matthey, we are also pleased to be associated with
specialist model engineering suppliers including, Dave Noble (3 cock water gauges, etc), Rob
Barker (traction engine fittings), Dave Tucker (loco fittings) and others too numerous to
mention. As we constantly strive to extend and update our range of fittings and supplies,
please contact us whatever your requirements.
All prices listed include UK VAT (sales tax). Customers for export outside the EU, may deduct
the tax from the listed prices. VAT on most items is 20%, although books are not taxed.
Prices are current at the time of publication of the catalogue, but are subject to revision in the
event of supplier price increases. Postage is additional on all orders, based upon the costs
incurred with the Post Office.
This is a metric catalogue, and products are sold by weight in kilogrammes and length in
metres. However, for the convenience of our customers generally working to imperial
standards, certain dimensions (e.g. thread sizes) are quoted in inches or feet. Note: 1 foot is
304.8 mm and 1 inch is 25.4 mm.
Details of how to order, together with an order form are provided in this catalogue. We have
NO MINIMUM ORDER CHARGE and international postage is no problem.

Section 3. Historic Engines Southwest
Polly Model Engineering Limited is pleased to be appointed exclusive distributor of this lovely
range of scale model stationary engines, designed by Anthony Mount. The majority of the designs
and their construction have been described in Model Engineer Magazine or Engineering in
Miniature and the range is still growing. Visitors to model engineering exhibitions can expect
frequently to see Anthony’s work on display (often winning high awards). The models are not
generally aimed at the beginner, although models such as Crosskill’s engine are well suited to the
less experienced and a determined beginner might well take on Murray’s Hypercycloidal. Kits
generally include all drawings, which are conveniently printed on a number of A4 sized sheets,
together with all the main castings required. Many of the castings are produced using the lost wax
process, in order to reproduce the intricate detail characteristic of the models. Some kits include
laser cut parts. The builder normally provides stock materials and fasteners, although these can
generally be supplied from our materials stock if required. Drawings for the engines are available
separately and if the castings are ordered within 6 weeks from delivery of the drawings, the cost of
the drawings is allowable against the kit price.
The table below gives prices for drawing and casting kits. Prices are in £ (GBP) and include VAT,
but postage is extra.

Books by Anthony Mount
The majority of models by Anthony Mount have been published in either Model Engineer
magazine or Engineering in Miniature magazine and where available the publication dates
are given in the summaries on the following pages. Design and construction details of some
of the more popular established models have recently been published in book form, in 2
volumes - Historical Engines Worth Modelling. Volume 1 describes the Rectilinear Engine,
the Steeple Engine, Crosskill’s engine, Boulton &Watt engine and the Hypocycloidal
engine. Volume 2 describes Benson’s engine, Grasshopper engine, Bodmer’s engine and
Simpson & Shipton’s engine. Price for these volumes is £12.95 each.
Bailey's Vertical Hot Air Engine
Bailey’s vertical hot air engine runs on the Stirling engine principles. Heated air
expands inside the hot cap and moves to the power cylinder exerting pressure on the
power piston causing the power stroke. At the same time displacer moves the now
cold air back to the hot cap for reheating.
The engine full size was rated at a 1/4hp, and was mainly used for pumping water. A
pump was fixed to the side of the engine and was driven by a crank on the flywheel.
They were built at the Albion Works Salford Manchester.
The model is attractive to watch in motion and is fairly simple to build. An extensive
range of castings is supplied with the kit. The firebox, displacer cylinder, water
jacket, power cylinder, bearing brackets, displacer cover and cylinder cover are
gunmetal castings and the flywheel which is 6” (150mm) diameter is cast iron. The
displacer is made from a brass tube. The hot cap is a stainless steel spinning. The
other parts (not supplied) are made from bar stock.
A set of 29 A4 drawings are supplied with the kit plus a parts list. The drawings have
dimensions in both imperial and metric.
The heat source can be a ceramic burner gas fired with Butane. A suitable burner is
available from Polly Model Engineering Limited who can also supply the gas valve.
The engine can be machined on a 3 ½” lathe, nearly all the work is turning with just a
little milling. A large fixed steady is needed for some of the turning.
It is good introduction to the world of hot air engines, and being a reasonable size the parts are not too fiddly to make.
Though the prototype was painted, the castings are so arranged that they can be machined all over. The polished
gunmetal and steel making an attractive combination.
The engine was serialised in Engineering In Miniature from March 1999 to December 1999.
Bailey’s Vertical Hot Air Engine (The Bee)
Founded by John Bailey in 1838 at the “Albion Works” Salford, Manchester, the company
was taken over by Johns son, Sir William Henry Bailey in 1866.
Bailey’s hot air engine (concentric version) was patented in 1881. In advertisements it was
called the “Bee”. It came in two sizes.
No 1, approximate power 1000 foot pounds, price £10, bright parts nickel plated £11 10s.
Total height 2’-9”. Suitable for driving shop window advertisements, model coffee mills,
roasting jacks, dental lathes etc.
No 2, approximate power 2000 foot pounds, price £15, bright parts nickel plated, £16 10s.
Total height 3-6”. Suitable for driving large sewing machines, amateur lathes, band sawing
machines etc.
The model is 17” (430mm) high. There are 28 drawings, A4 size. Both metric and imperial

dimensions are shown on the drawings. The firebox, legs, air cooler, water jacket, cover and pulley are gunmetal
castings. The flywheel which is 6” (150mm) diameter is cast iron. The whole was built on a Myford ML7R lathe,
VMC milling machine and the usual hand tools.
The model can be gas fired (Butane) using a ceramic burner. A suitable type being available from Polly Model
Engineering Limited as is a gas valve.
An engraving from a contemporary advertisement was used for the external details. The patent drawings (though they
varied considerably from the advertisement sketch) were used for the internals.
The model was described in Model Engineer from 21st September 2001 to 5th April 2002 alternate issues.
Benjamin Goodfellow Overcrank Engine 1851
I first came across this engine in the then Brighton and Hove
Engineerium, which at the time of writing is closed for refurbishment
but hopefully it will soon be open.
It is not a huge engine the flywheel being about 1500mm (5ft)
diameter, it is a delightful engine being from about the mid nineteenth
century and was used to drive a workshop. The Goodfellow Company
went on to build many large mill engines for the textile industry.
George Watkins who photographed the engine in the 1950s quotes the
engine as being 10hp with a pressure of 130psi and running at 90rpm.
The engine was installed in the cotton mill fitting shop of E. & G.
Hindle Ltd, Bastfield Mill, Blackburn. It was built in 1851 and was
still in use in the 1950s driving the fitting shed shop when the main
weaving shed engine was stopped. For interest the main engine was
probably built as single expansion twin cylinder slide valve horizontal
by W. & J. Yates 1870s, a new high pressure cylinder by Clayton and
Goodfellow was fitted in the 1880s making it a cross compound
Our little engine is in classical architectural style, lightly built and quite
tall for its size. Being a small engine I decided to make the model a
reasonable size so that the individual parts were not too small, opting
for a 200mm (8”) diameter flywheel, so it is still within the capacity of
most model engineers lathes, for example the Myford Series 7 lathes
will take just under 250mm (10”) in the gap.
The flywheel and cylinder are supplied as iron castings, the base, entablature, governor bracket and some other parts
are laser cut in mild steel. The ordinary bar material is not supplied.
There are 34 drawings of A4 size dimensioned in both metric and imperial. The engine was serialised in Engineering
in Miniature
Benson's Vertical Engine
This type of engine was called by the Victorians a vertical engine. An engine with
the cylinder above the crankshaft was called an inverted vertical. This engine was
built in the middle of the nineteenth century and is typical of the type. Incorporating
a forked connecting rod. Long piston rod which avoided a crosshead and slide bars.
It was simple in design and would have been built in small powers. Benson’s design
is unique as far as I know in using a single column to support the mechanism.
The design is attractive to the modeller in that the single column is easy to turn and
the entablature makes lining up the crankshaft simple. The governor is also large in
relation to the engine, which gives us a chance to make it operable in this small size.
A governor is also interesting to make and looks good in operation. The forked
connecting rod is shown with proper straps and wedges. But this could be simplified
to plain round ends with bushes if desired.
There was no scale given with my source material, but using my usual scale of 1/12
the full size flywheel would have been about 6’-0” diameter which gives a 6”
(150mm) diameter flywheel for the model. This makes up into quite a small engine.

The base, entablature and cylinder are gunmetal castings. The flywheel is cast-iron. The bracket, pump body and
eccentric straps are brass lost wax castings. Also supplied are the skew gear for the governor. The rest being made
from bar material.
A set of drawings are available all A4 in size and numbering 21. A parts list is also included. The drawings are
dimensioned in both imperial and metric. The imperial size being given first with the metric dimension below.
The engine was serialised in Model Engineer from 5th July 1996, Vol. 177 No 4020 to 31st December 1996, Vol. 178
No 4032, alternate issues.
Bodmer’s Sliding Cylinder Engine 1841
Bodmer’s sliding cylinder engine is rather unusual in that the piston is held in a
fixed position and the cylinder reciprocates. It was patented by Johann Georg
Bodmer in 1841. Bodmer was a Swiss of German descent, born in Zurich in
1786. He first came to England in 1816. He spent many years in this country
before returning to Zurich in 1860, he died in 1864.
He was a brilliant engineer and patented many designs, not only for engines but
locomotives, cotton machinery, marine work and much else. Amongst his
patents were Breech loading guns, the bayonet and its fixing to rifles, textile
machinery, the chain grate stoker, variable expansion valve gear with left and
right hand threads, commonly attributed to Meyer. Multi-syphonic locomotive
firebox, the slotting machine, the radial drilling machine, the rocking grate for
furnaces. The vertical lathe or boring machine, the idea of corridor trains. As
you can see he had a very fertile mind. He had his own engineering works first
in Bolton and later in Manchester and introduced the metric system there. A bit
of a workaholic, he often worked a 16 hour day.
The sliding cylinder engine appears amongst a number of inventions all under
one patent. Whether it was ever built I do not know, but some of his designs
were built at his own factory. His drawing shows it arranged for use in a paddle
ship but he does note that it is also suitable for land use. I have arranged it as a
stationary land engine. The columns and frames following along the lines of
other engines by Bodmer.
The model has a 9” (228mm) diameter flywheel, and the castings for base, entablature and cylinder, covers are in
gunmetal and the flywheel is cast iron. Drawings and parts list are available and there are 30 in the set, all of A4 size,
and the dimensions are in both imperial and metric.
The model can be built on a 3½” gap bed lathe, though a milling machine does make things easier. The model was
serialised in Model Engineer from 11th August 2000 to 23rd March 2001, alternate issues.
Boulton and Watt Bellcrank Engine 1802
The Bellcrank engine was introduced by Boulton & Watt in 1802. The design was formulated by William Murdock
and the Soho foundry manager a Mr Southern. The aim was to supply a small self
contained engine, to the smaller manufacturer who could not afford a house built
beam engine. The design was called a Bellcrank on account of the shape of the
rocking leavers. These resembled the leavers that transferred the pull of the ropes in
a bell tower to the bells.
The design was in production from 1797 until 1806, when Boulton & Watt
introduced their small self contained beam engine mounted on a cast iron cistern.
From my research all the engines seemed to vary slightly one from another. The
earliest engines were filled with a form of drop valve. Then came the long D valve,
followed by the slide valve. The model is based on one from 1802 with a long D
valve.
The drive to the valve is interesting. Bolted to the flywheel is an eccentric ring. A

forked end of a lever pivoted on the cylinder, fits into the ring. As the flywheel revolves the lever is raised and
lowered. On the other end of the pivot shaft is another lever. This lever fits into a slot in a shaft that slides up and
down while attached to the steam chest. The sliding shaft has a link at the top which attaches to the valve rod.
The base of the engine is a cistern, inside there is a condensing tank. The cylinder is also mounted on the cistern as are
the crankshaft bearings. The flywheel is carried on a separate shaft mounted in its own bearings.
The model is to a scale of 1 3/16” to 1ft, which gives a flywheel of 9” (225mm) diameter. Castings are for flywheel,
cam ring, cistern, condenser, cylinder, covers and steamchest. There are 26 drawings and a parts list in the set, all are
of A4 size. The drawings have both metric and imperial dimensions.
Construction is quite straight forward, and can be carried out on a 3 ½” lathe. A drill and mill will make things a bit
easier of course. One variation from the norm is the long D valve, which is not self sealing like a traditional slide
valve. It can be viewed like an inside admission piston valve. Except that the heads are not circular but D shaped. The
valve is hollow and exhaust from the top of the cylinder passes down through the valve to reach the condenser.
Serialisation of the model began in Engineering In Miniature July 1993 and ended in June 1994
Cross Engine
The Cross engine uses an unusual arrangement to convert
reciprocating to rotary motion, called a rectilinear motion. An engine
using this motion was patented by James Booth in 1843 and a model of
his engine is available from our collection.
This model uses the same motion but with a much simpler detail design. It is
based on another model in the collection of a friend of mine, though
unfortunately there is no indication of the period it was built and who made it.
It is difficult in words to describe the motion, but in essence the cross acts a
guide frame for two crossheads (sliders), one moves vertically and the other
horizontally. The end of the piston rod is connected to the vertical slider,
joining the two sliders together is a link which has three equally spaced holes
in it, same pitch as the crank throw. The crankpin is connected to the centre
hole, as the sliders move up and down and across; the centre hole of the link
drags the crank around.
I followed the original concept of the model but drastically altered the details. Following as much as possible the full
size engine details of the 1840s period I think it looks a good representation of how such an engine would have looked
like for that period. Castings are provided for the flywheel in cast iron and in gunmetal for the cylinder. Laser cut mild
steel laminations are provided for the base, entablature and guide cross. Also supplied is a full set of 23 drawings all
of A4 size and both metric and imperial dimensions are shown on the drawings.
The model’s flywheel is only 138mm (5 7/16”) diameter so well within the usual model engineers lathe capacity. The
model stands about 300mm (12”) high on its wooden base.
The engine was serialized in Engineering in Miniature from March 2009 to October 2009
Crosskill's Oscillating Engine
The design for this engine was taken from a book published in the 1870s. One page
contained a number of small thumbnail sketches of engines including Crosskill’s oscillating
engine. Though no scale or size was given, it was presumed that it would have been a small
engine of about six horse power. This type of engine would have been used to power a
small workshop or individual machine. The model though based on Crosskill’s design is not
an exact copy in miniature. It has been modified to make it easier to build in this small size.
The prototype had both a slide valve and governor, these have been omitted. The governor
would have required a microscope to build it. The idea for this engine is one that while
looking attractive, has only a small number of parts, and will not take long to build. It is

aimed at newcomers to the hobby and those wanting a change from a more demanding project.
Four castings are required, flywheel, 3” (75mm) diameter, base, table and cylinder. The other parts are machined from
rod and bar material. The castings are made using the lost wax process, which should give well detailed castings. The
design requires quite a number of interesting machining operations, covering most of the standard machining methods
met with in model engineering. As such, it is a good introduction to the hobby. Being small, it is within the range of
many of the small lathes available today. A drilling machine and mill will of course make life easier, but they are not
essential. All the machining could be performed on a lathe equipped with a vertical slide.
There are 9 drawings in the set plus a parts list, and all are A4 size. They are dimensioned in both imperial and metric.
The imperial dimension appears first with the metric below. Drill sizes are given only in metric as these are now
preferred. You will notice that the dimension conversions are not exact, the desire being to use standard material
sections from both systems. There are twenty main parts to the design.
The engine can be run on both compressed air and steam. A small compressor of the air brush type will be adequate,
only about 10 psi is required. Included in the package, with the castings and drawings, is a descriptive booklet giving
details on model construction.
Easton and Anderson Grasshopper Beam Engine
The grasshopper beam engine is so named because it is supposed to resemble
a grasshopper when in motion. The Grasshopper engine was introduced in the
1820s and was built by many companies, but Easton and Anderson
specialised in the genera. This model is based on an example supplied to
Winchester gasworks in 1892. It was used to drive the gas exhausters that
pulled the gas from the retorts and pumped it into the gas holders. The
prototype was photographed in 1936 by George Watkins and was published
in his book, “Stationary Steam Engines In Industry Vol 1, Fig 89”. 1892 is
quite late in the thy for a grasshopper engine, but it does contain some
“modern” features, such as double beam, single marine type big ends, disk
crank, Meyer valves and Tangye governor. As a hole it has quite clean lines.
The model follows the prototype quite closely, but though it has an air pump,
no condenser is fitted. The governor though it revolves is non operational.
There are two eccentrics operating a concentric rocking shaft. But there is only one slide valve fitted, the other valve
rod is a dummy. The two eccentrics are fitted as the concentric shaft is such an interesting feature.
The engine is quite small with a flywheel of 5” (125mm) diameter. Construction is quite straight forward, but some
parts are quite small. Castings are available for the flywheel, base, cylinder, covers, rackets, rocking frame, and beams.
There are 34 drawings and a parts list, all of A4 size. The dimensions are in both imperial and metric, you will find
that some of the conversions are not exact as standard material sections are used where possible. The imperial
dimension appears first with the metric dimension below. Drill sizes are given only in metric as these are now the
preferred size.
The model can be built on a 3½” lathe, being quite small it might be possible to build it on some of the smaller lathes
now available. All the work could be done on the lathe especially if a vertical slide is used. However a drill and mill
will make things a bit easier.
The engine does look very attractive in motion. The spinning governor is an added attraction. This was supplied by
Tangye, a Birmingham company, and it is not known if this arrived with the engine or was added later. It was Tangye
who supplied the Hydraulic rams that were used to assist the launch of Brunel’s Great Eastern steam ship. Grasshopper
engines have also been used in marine work, some were installed in tugs.
The model was serialised in Engineering In Miniature from June 1992 to May 1993.
Farcot's Table Engine
For details of this engine I am grateful to a friend in France who kindly sent over some drawings of French stationary
steam engines taken from a book published in the 1860s. It was in two volumes, text and plates, but only the plates had
survived. So I am unable to give any background information on the engine to be described. Except that Farcot was a
major manufacturer of engines and machinery in France and his name crops up quite often in French steam engine
books.

The moment I saw the engine I thought it looked very elegant and would make a very attractive model. The more I
looked at the design the less I felt that castings would be needed. The only way to get the detail required would be with
lost wax castings, and this would be prohibitively expensive with the quantity and sizes required. Therefore I opted for
a fabricated design.
All the parts can be machined on a Myford S7 lathe, except for the flywheel. This is 400mm diameter and only 8mm
thick. The bosses are bolted on as in the prototype, so I had the flywheel profile milled from plate including the +
section spokes. If there is sufficient demand these can be supplied ready milled.
An alternative will be a laser cut mild steel blank and you can mill the webs
of the spokes yourself. The cylinder was double steam jacketed, so
while the cylinder looks very big and powerful the working cylinder
was in fact quite small. I have used only one jacket in the model and
the design lent itself to be made from continuously cast phosphor bronze
tube (easy machining type). The cylinder was a most enjoyable exercise to
build, as it was machined on all surfaces. No castings to clean up.
As you can see from the photograph the entablature, connecting rod guides
and governor bracket are very ornate. As for the governor this is in a class of
its own. At first glance a standard Watt type. Its operation gets more and
more involved the further you look into it.
As the governor operates it engages with three bevel gears in a sort of
differential gear. As it rises it drives one way, as it falls it drives the other.
This motion is transferred via another set of bevels to a vertical drive shaft.
The other end of the shaft ends in a worm and wheel, pivoted in the centre of
the steam-chest, which is itself circular.
In the prototype the valve consisted of two slide valves one on top of the
other, along the lines of Meyer valves. As the centre pivot moved by the
action of the governor it opened and closed the top valve altering the cut off.
To the left there was another lever that through a shaft terminated with a spur gear in a pocket behind the slide valve.
The lever could be pulled forward engaging the gear with a rack along the side of the valve. Thus the slide valve could
be moved independently for starting purposes.
I expect all the parts could be made for the model, but there would not be the power from the governor to drive the
bevel gears let alone the slide valve. So I built the governor as a decorative but non operational mechanism. The
wheels go round but nothing happens.
The large size of the flywheel requires the whole engine to be raised up to clear. Either by putting the engine on a
stone or brick pedestal or building a deep wooden base to house the lower half of the flywheel.
I have shown the air pump as it is quite distinctive and indicates that the engine was of the condensing type. But like
the governor in does not need to work, as I suspect nobody will ever run the engine as a condensing engine.
No materials are being supplied for this engine only a set of drawings, which consists of 41 all of A4 size, plus a parts
list. The dimensions are shown in metric only. The model has been serialized in Engineering In Miniature from
November 2003 to August 2004.
Galloway's Non Dead Centre Engine
Galloway’s non dead centre engine was patented in 1838 by
Elijah Galloway and was an attempt to build an engine with
the advantages of self starting in any position with the
simplicity of a single crank.
As can be seen there are two vertical cylinders connected by
a connecting rod of triangular configuration to a single crank
placed between the cylinders. As the pistons are 90 degrees
out of phase to each other there is never a position where the
piston of at least one cylinder cannot bear upon the crank.
During each revolution the top beam of the connecting rod
goes from horizontal to an angle as the piston rods are in a
fixed plane some means of extending the beam is required. This is accomplished by having sliding bearings in the
crossheads.

To keep the centre of the connecting rod beam in a straight vertical line, a motion beam is connected to the centre of
the connecting rod beam and goes via mother sliding bearing housed in brackets to the side of one cylinder to another
tie rod which goes back to the brackets. This sort of “parallel motion” constrains the connecting rod into a straight
vertical line.
Having a lever going up and down to the side of the engine it was a convenient place to put an air pump driven by said
beam.
The engine was designed for marine use driving paddles and for land use as a stationary engine. It was built but was
not used a great deal at the time. It was reinvented by Bernay’s in 1874 and again in 1887 by Fleming and Ferguson,
who used it as a marine engine driving screws. In this instance the cylinders were inverted. It was licensed by Fleming
and Ferguson to Musgrave’s who built as a compound, triple and quadruple expansion mill engine. A small compound
has survived and is in the care of The Northern Mill Engine Society at Bolton.
The model was built using a Myford ML7R lathe and VMC milling machine. There are 40 drawings all to A4 size,
dimensions are in metric only. The flywheel is 228mm (9”) diameter. Castings for the cylinders, covers, pistons, air
pump, covers and steamchests are in gunmetal. The flywheel is cast iron.
The engine is fascinating to watch in motion, it has to be seen to be believed.
The engine was serialised in Engineering In Miniature from August 2001 to June 2002.
James Booth's Rectilinear Engine 1843
This unusual engine was patented by James Booth in 1843. His hopes for the
design were that it would give a compact layout for use in paddle ships, and
for driving machinery on land.
The term rectilinear derives from the action of converting reciprocating
motion to rotary. As you can see from the picture, this was accomplished by
a set of links, connected to the crossheads. The crossheads run in guides in
the form of a cross. The reciprocating motion of the piston drives one end of
the link, connected to the vertical crosshead. The other end of the link is
connected to the horizontal crosshead, which is pulled across. The combined
motion pulls the centre of the link around in a circular path. Attached to the
centre of the link is the crank from which is derived the rotary motion. This
arrangement removes the need for a connecting rod, which greatly reduces
the height of the engine. However is does increase the number of rubbing
surfaces. I have been unable so far to determine if the engine was ever built
full size.
The design of the model was developed from the patent drawings. It follows
fairly closely the spirit of the prototype but some details had to be guessed at
as their arrangement was not shown. A standard slide valve is used for steam distribution. A main stop valve is also
incorporated into the design, and sits adjacent to the valve chest.
Construction is straight forward, but care is required to ensure that the guide frames line up on the centre line of the
crankshaft. The flywheel is 9” (225mm) diameter which allows for machining on a Myford series 7 lathe. Machining
follows the usual model engineering processes and most can be done on the lathe. It is of course easier if a drill and
milling machine can be used as well.
Castings are required for Flywheel, and pulley which are in cast iron, cylinder, covers, piston, steam chest, eccentric
strap and guide frames are in gunmetal. The bearing frames being in aluminium. The base is a 3/16” (5mm) thick mild
steel plate. Other parts are machined from rod and bar material. There are 20 drawings in the set, plus a parts list. They
are dimensioned in imperial and metric. Some of the conversions are not exact, as standard material sections have been
used where possible.
The model was serialised in Engineering In Miniature, from December 1989 to October 1990. The engine when built
is fascinating to watch, the motion is really unusual. It appears as if the flywheel is revolving one way and the links are
revolving in the opposite direction.

Kientzy Oscillating Engine -Drawings ONLY
The source for this model design was an engraving from a French book on steam engines
published in the 1860s. Though I would imagine the design to be from the 1850s. But
with a name like Kientzy I do wonder if it was indeed French. There was no text with the
engraving by way of explanation.
Oscillating engines are about the simplest steam engine you can get. They were built
from tiny little workshop engines, up to pairs of 100” giants for use in paddle ships. All
the larger engines including our prototype had a slide valve to distribute the steam. But
the valve gear if you can call it that consists of a quadrant and valve rod. The movement
of the cylinder giving motion to the valve. Most steam engine types are associated with
their original designers, for example, beam engines with Newcomen, Steeples with
Napier, Bellcranks with Boulton and Watt, Siamese with Maudslay, but who originated
the oscillating engine? I seem to remember a small double oscillator in the Science
Museum by Maudslay from 1815.
Our prototype is a great looking engine and runs quite smoothly considering the amount of movement from the
cylinder. I have modified the design slightly from that drawn, as the outer end of the crankshaft was carried in a wall
box. A wall box was a cast iron structure built into the engine house wall to take a bearing pedestal.
The flywheel is 225mm (9”) diameter and is an iron casting. The frames, governor brackets, eccentric strap and slide
valve are brass lost wax castings. The cylinder is also of the lost wax type but in bronze. The foundation is an
aluminium casting in heat treated LM25 which machines very nicely. The engine can be machined on a lathe of the
Myford series 7 size.
There are 30 drawings of A4 size and the engine was serialised in Engineering In Miniature from May 2005 to
February 2006.
Denny Improved Ericsson Engine
The Denny Improved Ericsson Hot Air Engine was introduced at the beginning
of the 20th Century by the American Machine Company of Newark Delaware. I
was told that Denny was the chief designer for the American Machine
Company. The original engine was designed by the famous Swedish engineer
Ericsson.
The engine runs on the principles invented by Robert Stirling in 1816. It is a
Stirling hot air engine. It has the piston and displacer concentric to each other
in the same cylinder. The full size engine was intended primarily as a pumping
engine. Such duties as pumping water from a well to the cistern of a large
house or factory. In the countryside it would have pumped water from artesian
wells to water cattle or for irrigation. A pump is integral with the design and is
detailed on the model. It was built in a range of sizes and was popular in the
USA as it could be run by anybody whereas a qualified engineer was required to attend a steam engine. The model
engine is based on a drawing in the original catalogue and from photographs of a preserved engine. If the photographs
can be believed it was painted an orange/red colour.
The model is about 250mm (10”) high and has a 100mm (4”) diameter flywheel, as such it can be built on most model
engineers lathes. It is supplied as an Iron casting for the flywheel, Gunmetal castings for the base, firebox, water
jacket and beam pivot bracket. Laser cut mild steel parts are supplied for the main frame, bell cranks and beam. Also
supplied are stainless steel tubes for the cylinder and displacer. The other small parts are fabricated.
A set of 30 A4 drawings are supplied and the dimensions are shown in both metric and imperial. The model is easy to
build and with a 30mm (1 3/16”) diameter piston has enough power to be easy to run. Tiny hot air engines can be a
problem at times to overcome their own inertia. It is designed for a ceramic gas burner but other sorts of burner could
be used instead. This engine was serialised in Engineering in Miniature from June 2006 to March 2007.
M’ A de Polignac’s Curved Cylinder Engine
This engine was designed by M’ A de Polignac in France in the 1870s. The engine is unusual in that the cylinder is
curved along its length. The piston is also suspended in a frame and swings like a pendulum. It was claimed that this
form of construction relieved the cylinder of wear, and allowed for a fast running engine.

The engine was available from the catalogue of a M’ Oppennan.
The design was published in a book of 1875, which had been
edited in 1873. The illustration on which I based the model was
for an engine of 6hp. As you can see from the illustration the
engine is of light construction. A speed of 500 rpm was
claimed, and that the engine had been tested to 750 rpm. It was
a small engine with flywheels 500mm diameter. I chose a scale
of 1/5 which gave a flywheel diameter of 100mm. The cylinder
bore is 19mm diameter. The engine was used to drive
woodworking machinery where the high speed was put to good
use. Though it was originally a metric design I have used dual
measurements on the drawings. Showing imperial first with the
metric dimension below. You will notice that they are not exact
conversions. Standard material sections have been used where possible.
The set of drawings comprise 20 in number plus a parts list, all to A4 size. Both metric and imperial dimensions are
given on the drawings. There are five castings, an aluminium base, gunmetal for the cylinder, covers and eccentric
strap. The rocking frame is a laser cut mild steel plate, as are the side frames, the webs being soldered on to represent
castings. The flywheels and pulley wheel are machined from free cutting mild steel blanks. All other parts are made
from bar and rod material.
The curved cylinder was machined full size using a horizontal boring machine and a large rotary table. In the model
the curved bore was machined using a metal jig that was pivoted on the back of the cross slide. An extension being
bolted to the back of the cross slide to get the pivot point far enough back. The other end was forked around the
toolpost on the top slide. The top slide being used to apply the feed to a boring tool held in the chuck. The cylinder
casting was clamped to the jig.
The engine runs very smoothly and is fascinating to watch in motion. It is quite a simple engine and can be machined
on a 3 1/2” lathe. The laser cut frames save a lot of work. The connecting rod is an interesting piece of machining
being fish bellied.
The engine was serialised in Engineering In Miniature from June 1995 to December 1995.
Maudslay Columnar Engine 1862
I first saw the prototype of this engine as a child when taken to the Science Museum
South Kensington by my parents during the school holidays. It was a wonderful
exciting place full of models that you could set in motion by turning a handle or
pressing a button, plus full size exhibits that towered over the small visitor.
The prototype was built by Maudslay Sons and Field to power their exhibits at the
1862 International exhibition which was held at South Kensington, not to be
confused with the Great Exhibition of 1851 held at Hyde Park and later transferred to
Crystal Palace, so the engine has not stayed far in its existence. By the time of the
International Exhibition Henry Maudslay had died and the company was being run
by his sons, so I do not know who designed the exhibition engine but it does have
wonderful lines. As is often done for exhibitions the engine was given a special
finish, in this case the whole of the engine apart from the flywheel is in polished
gunmetal and looks absolutely super.
I made the flywheel 178mm (7”) diameter which is roughly half size and well within the capacity of the usual model
engineers lathe such as the Myford Series 7 lathes. The main column is a big casting and I did mine on a Warco
BH600 lathe rather bigger than the Myford as it has a large fixed steady necessary to support the column. A vertical
milling machine is essential for some of the machining.
Castings are available for the column, inner and outer cylinder, top and bottom cylinder covers, base ring and
flywheel. Apart from the cast iron flywheel and laser cut mild steel base, all the other parts are in gunmetal, so the
castings for this engine are more expensive than usual, to counter this there is very little that needs painting.
There are 27 drawings of A4 size in the set and as is my usual practice they are dimensioned in both metric and
imperial. The castings and drawings are available from Polly Model Engineering but as they are quite big and weigh a
lot they are to individual order. There are plenty of parts to make while waiting for the castings. The engine was

Murray's Hypocycloidal Engine
This engine has an interesting pedigree. Originally introduced by Matthew
Murray in 1802. It was one of a number of engine designs produced after the
Boulton and Waft patents expired. It could be classified as a portable engine, in
that it was not house built, being self contained it could be erected anywhere. It
was of about 5hp and was condensing, working at a low pressure.
A unique feature of the engine was the hypocycloidal motion, whereby
reciprocating motion was transformed into rotary motion. The geometric
principle is that a point on a circle rolled around the inside of another circle of
twice the diameter will scribe a straight line. In practice the small circle is a
spur gear which rolls around inside a ring gear with internal teeth. As the
piston rod rises and falls, the end is pivoted on a pin fixed on the periphery of
the small gear. The small gear rolls around and through a crank drags the
crankshaft round.
The model is based on a later engine than Murray’s original. It was built by John Bradley and Co (Stourbridge) Ltd
and is in the Henry Ford Museum at Dearborn, Michigan. It was used for pumping water. In the model the pump is not
included, the desire being to show only the hypocycloidal mechanism. Another engine from the same company but
possibly of earlier design is in the Birmingham Museum of Science and Industry.
One reason for choosing the prototype was that it had cast plate frames and base. This has lent itself to reproduction by
laser cutting, the same method being used to provide the gears and flywheel. The flywheel has only four spokes and
these are quite thin, which made the possibility of having them cast doubtful.
The cylinder, covers and steamchest are gunmetal castings. There are 19 A4 drawings in the set plus a parts list. All
dimensions are in both metric and imperial. The engine can be built on a 3½” lathe, though not essential, a milling
machine will make things easier. The engine was serialised in Engineering in Miniature from October 1996 to June
1997. It is a most fascinating engine to watch in motion.
Savage Organ Engine – drawings ONLY
These little engines were used to drive fairground organs. They were sometimes
mounted at the back of the organ, at the front of a traction engine, or on the
centre engine of a carousel.
Savage’s were of course a famous engineering company producing agricultural
and fairground steam machinery in both the 19th and 20th centuries. They were
based at Kings Lynn in Norfolk and the town museum contains much
appertaining to the company as well as storing a large number of the companies
wooden patterns.
The company was founded in 1850 by Frederick Savage, who had been born on
3rd March 1828 in the village of Hevingham in Norfolk. At the age of sixteen he
started work with Thomas Cooper “Whitesmith and Machine Maker,” who had a
small foundry in East Dereham Norfolk. It was taken over by John and James
Gill, “Millwrights and Machine Makers.” In 1848 Savage moved to Lynn and
gained employment as a wheelwright and blacksmith with Charles Willett. who
styled himself as “Brazier, Tinplate worker, Ironmonger, Wholesale and Retail
Dealer, Whitesmith and Belihanger".
In 1850 Willett retired and Savage set up on his own account with a small
smithy and foundry. Business expanded and he moved in the next few years to
ever larger premises. In 1872 came his last move to the north end of town to
new premises he called The St Nicholas’ Ironworks. He was now known as
“Engineer and Agricultural Machinists”. He also became a J.P. and in 1889-90 the mayor, and he had a statue erected
as a monument to him. He died on 27th April, 1897, aged sixty-nine.
A good write up of the company is given in the book “The Engine Builders of Norfolk” by Ronald H Clark, who also
did a separate booklet on the 114th anniversary of the company.
The model has a cast iron flywheel of 150mm (6”) diameter. The frame, pedestal bearings, governor bracket and
governor slider are brass lost wax castings. The cylinder is a gunmetal lost wax casting.

The base is made from 7 laminations of laser cut steel, also laser cut are the governor arms and links, and the throttle
lever.
With quite a small flywheel it should be possible to build the engine on some of the smaller lathes available as well as
the usual 3 1/2" machine.
The engine was written up in Engineering In Miniature from October 2004 to April 2005.
Scotchcrank Engine 1846
The Scotchcrank engine is unusual in that no connecting rod is required. The
reciprocating motion is converted to rotary motion by the piston rod having a
horizontal slot in which fits the crankpin. As the piston rod rises and falls the
crankpin moves along the slot giving rotary motion to the crankshaft.
I have never seen an explanation as to why the motion is called “Scotchcrank”.
The design is attractive not only for the unusual motion but for the delightful
architectural features of the period in which it was built.
Due to the form of construction most of the parts are fabricated. Gunmetal
castings are used for the cylinder. The slide valve is of conventional form but is
housed in a steamchest as used for long D valves. Also of interest is that the
steam inlet and exhaust come up through the columns and enter and leave the
cylinder along the same centreline.
The entablature core and beading are fabricated. The base is a 5mm thick mild
steel plate.
The cast iron flywheel is 9” (228mm) diameter and has eight spokes. The cylinder is 3 1/8” (80mm) long and F’
(25mm) bore. A Watt type governor is fitted.
The model can be built on a 3 ½” (89mm) lathe, a milling machine is a help but a vertical slide should cope with most
of the milling operations. A full set of 26 drawings of A4 size are available, and have imperial and metric dimensions.
The model was described in Model Engineer from 20th November 1998 to 4th June 1999, alternate issues.
Simpson and Shipton’s Short Stroke Engine 1851
This engine was patented by two Manchester engineers,
Joseph Simpson and James Alfred Shipton in 1848. It is a
rotary steam engine, but it still uses connecting rods to drive
the crankshaft. The “cylinder” or perhaps better described as
a chamber, sits on a table carried on four short columns.
Inside the chamber is a “piston” lying on its side. Passing
through the piston is an eccentric shaft, connected to the
outer ends of the shaft are cranks. Connecting rods drop from
these cranks to the crankshaft carried on bearings fixed to the
base. Steam enters the chamber through a balanced slide
valve and impinges on the side of the piston rolling it around
inside the chamber.
The claim for this arrangement was a compact smooth
running engine. Against the design are the problems of sealing the length and ends of the piston. Full size this was
achieved by having a flat spring loaded plate bearing against the side of the piston. The ends were sealed by split
coned rings seated in coned recesses in the ends of the piston. By expanding the ring with a wedge the ring rode up the
coned recess and increased the length of the piston sealing the ends. In the model the length wise sealing is achieved
by using a very slight interference fit. The ends are sealed with rings of graphited yarn dropped into grooves machined
in the piston ends.
Construction of the model is quite conventional without any odd machining practices. It can be machined on a 3 1/2”
lathe, the flywheel being 9” (225mm) diameter. There is quite a lot of milling involved, and while this could be done
using a vertical slide. A vertical milling machine does make things a lot easier. The bigends are of the strap and coffer
type. Castings are available for the base, table, cylinder, piston, covers, steamchest, steamchest cover, eccentric strap

and flywheel. There are 23 drawings plus a parts list and all are of A4 size. The drawings have both metric and
imperial dimensions. Except that all drill sizes are given in metric as these are now the preferred size.
The engine does look very interesting when in motion, there are levers gyrating all over the place. It is also very free
running and only requires a wisp of air to get it running. How many of these engines were built full size is unknown,
but an engine was exhibited at the great exhibition in 1851 where it drove textile machinery. There is also a reference
to the engine in the “Engineer” in 1862. Still with the same cylinder arrangement, but with a different drive
mechanism. The model was serialised in Engineering In Miniature in August
1994 to May 1995.
Steeple Engine
A Steeple engine (illustrated right) is so called because of the resemblance of the
piston rod extension to a church steeple. It is sometimes confused in model
engineering circles to a table engine, but the difference is quite easy to see. The
cylinder in a table engine literally sits on a table. With the crankshaft below the
table. With a steeple engine the cylinder sits at floor level and the crankshaft
passes over the cylinder. This is apart from marked differences between the
piston and connecting rod arrangements.
Steeple engines were an early attempt to get away from the beam engine
arrangement. The first steeple engines were designed by Napier in the 1830s for
use in paddle boats. The cylinder went in the bottom of the boat, the crankshaft
was at deck level, and the upper section was housed in a deck house.
The model is based on a land engine of the 1860s. The flywheel construction is
quite interesting. Full size the boss and rim were cast around wrought iron spokes
laid in the foundry mould. This is not possible in a model, so the boss is built up
and the rim is a gunmetal casting that can be machined all round. The spokes are rods Loctited in position. The lathe is
used as a jig to hold them in position while the Loctite cures.
The model has a 9” (229mm) diameter flywheel. The base, flywheel rim, main frame, cylinder, steamchest and
eccentric strap are gunmetal castings. The other parts are machined from mild and stainless steel bar stock.
A full set of 22 A4 drawings are available plus a parts list. The drawings have both imperial and metric dimensions.
The engine is a delight to watch in motion and an interesting project to build. Construction is possible on a 3 ½”
(90mm) gap bed lathe. The gap being needed for the flywheel. This engine is also available as a ready to run model or
fully machined kit. This engine was serialised in Engineering in Miniature from January 2000 to August 2000.
Stockport Engine
I first came across the inspiration for this engine some years ago in a book
published in the 1890s on gas engines. An illustration in the book showed a
small 3/4hp gas engine made by J.E.H. Andrew & Co in their Stockport
works. They also produced very large horizontal gas engines. The engine
was unusual in that it had a steeped piston the larger upper portion
compressed the mixture and the lower smaller diameter part of the piston was
where the charge was ignited by hot tube ignition.
As I only had an external elevation and was unable to find out anything more
about the engine I put it to one side, but I liked the appearance of the engine
so decided to modify the engine to work as a vacuum engine. These engines
are also called atmospheric hot air engines, flame gulpers and flame lickers.
The engine works with an external flame which is sucked into the engine
when a slide valve opens, the cylinder fills with hot air, the valve shuts then
the hot air is condensed and atmospheric pressure drives the piston down and
the process is then repeated. They produce little power but make a good
noise and run well and are easy to make. It is designed to run on Butane gas
and details of the burner arrangements are given in the drawings.
The flywheel and base are supplied as iron castings, the cylinder and piston
are continuous cast iron bar. The column is a piece of steel tube and the top of the column is machined from a block

of steel. Also supplied is material for the carbon/graphite valve and the springs and a laser cut blank for the
crankshaft. The ordinary bar material is not supplied. There are 22 drawings of A4 size dimensioned in both metric
and imperial and the castings and all materials including the springs are supplied in the kit. The engine can be
machined on a lathe of the Myford series 7 size or even smaller as the flywheel is only 150mm (6”) diameter and the
engine was serialised in Model Engineer from 5th June 2009 for three consecutive issues then alternate issues.
Trapezium Connecting Rod Engine
This example of a trapezium connecting rod engine is attributed to
Professor Realeaux, who was professor of Kinematics at Charlotenburg
University Berlin and was taken from a Dutch textbook published in the
1890s. As can be seen the connecting rod is in the form of a trapezium and
completely encompasses the cylinder. The motion is most interesting and
makes for an attractive model. It would probably have been in the range of
5 to 25 NHP range. Alas few details are given in the text. I have presumed
a 9ft (2.7metre) flywheel, which conveniently at 1/12 scale gives a 9”
(228mm) flywheel.
The base and brackets are aluminium castings. Gunmetal castings are used
for the cylinder, covers, steam-chest and eccentric strap. The flywheel is
cast iron. The connecting rod yokes are mild steel fabrications. The valve
is of the slide valve type. To support the crankshaft there is an outrigger
bearing.
There are 20 A4 drawings which have both imperial and metric dimensions, also included is a parts list.
Construction is quite straightforward and can be performed on a 3 72” (90mm) lathe such as the Myford series 7, with
a gap bed. Though not essential a milling machine does make some operations easier.
The model was serialised in Engineering In Miniature from July 1997 to February 1998.
Tuxford's Double Side Rod Engine
This model of Tuxford’s Double Side Rod Engine was developed from a small
engraving in a book published in the 1880s. The engine can be viewed as
midway between a Table engine and an Oscillating engine. As with the table
engine there is a table, but the cylinder is placed under the table. The piston rod
drives upwards to a cross beam. From the crossbeam rods drop down to
crossheads sliding on guides attached to the side of the cylinder. Pivoted from
the crossheads are connecting rods which rise upwards to the crankshaft.
Because of this arrangement the crankshaft has to have a very long crankpin the
full width of the cylinder. The reason for this arrangement was to obtain a
compact engine but with the long connecting rods of the true table engine.
Though more compact than the Table engine it was not as simple as the
Oscillating engine.
There was no size or scale given but if we assume a 9ft (2.7metre) flywheel this
would give us a 1/12 scale and a 9” (228mm) flywheel for the model. There are
26 drawings in the set all A4 size, and are dimensioned in both imperial and metric.
The imperial dimension appears first with the metric dimension underneath. You will notice that the metric dimensions
are not exact conversions from the imperial, I have tried to use standard metric stock sizes where possible.
The construction of the engine has some interesting operations, and the whole builds up into an attractive engine of
quite small size, but without any tiny parts. The number of castings have been kept to the minimum and consist of just,
flywheel pulley wheel, base and cylinder.
When built up the engine runs quite smoothly with a majestic motion, the movement of the engine is most attractive to
watch. I hope you enjoy building and running the engine.
The engine was serialised in Engineering In Miniature from January 1996 to September 1996.

Waller's Table Engine
The first table engine is credited to Henry Maudslay in 1805, and the type was built by many manufacturers during the
nineteenth century. This example is a later one from the 1880s. Details came
from a book published in the 1880s and the author was a director of George
Waller and Co. There was a short note on the engine in the text and the
wording was such that it indicated that the engine was still available at that
date. It was also stated that while horizontal engines were cheaper in first
cost, the table engine took up a small amount of floor space and did not
often get out of order.
The design follows the classical architectural style, though slightly less
ornate than some earlier examples. As with all table engines it has a majestic
stately motion, a pleasure to watch. It is quite easy to build the majority of
nuts being of 8BA (M2.2) size.
There was no indication of size on the engraving but if we take the flywheel
as 9ft (2.743M) and a scale of 1/12 we arrive at the convenient size of 9”
(228mm). The design is such that the base and table can easily be machined
from mild steel blanks. As can the columns, and an interesting feature being
that two of the columns form the steam and exhaust pipes. A is used for the
flywheel.
The cylinder is described in the article as a fabricated design, however a
gunmetal casting is now available and a cast eccentric strap.
Drawings are available as a set of 27 of A4 size. They have dimensions in
both imperial and metric.
The engine can be built on a 3 1/12” lathe and though not essential a milling
machine is also useful. The engine was serialised in “Engineering In Miniature” from March 1998 to February 1999.
Whitmore and Binyon Fixed Engine
I came across this engine through the good offices of a friend who knowing my interest in unusual engines let me have
a copy of an engraving he had.
The engine was designed by
Whitmore and Sons of Wickham
Market, Suffolk, and was exhibited
at the International Exhibition at
South Kensington in 1862, (not to
be confused with the Great
Exhibition of 1851), where it
gained an exhibition prize medal.
The company in 1868 changed its
name to Whitmore and Binyon.
The company was founded by
Nathaniel Whitmore in 1780 as a
smithy for hand tools and
agricultural machinery.
The main purpose of the unusual
design was to drive direct by belt
the vertical spindles of the old style
flour mills. The engine engraving
shows two pulley wheels but an
engraving of the mill shows the
engine driving three stones.
The base of the engine is a great cast iron drum within which is the flywheel, four Corinthian columns support an
entablature which carries the upper bearing. An additional bearing above the pulley wheels was bolted to the mill
framework. This is not shown on the model. The flywheel is 215mm (8 ½") diameter and machinable on most model

engineers lathes such as the Myford ML7 series. The flywheel is supplied as an iron casting and the cylinder is a
gunmetal casting. Due to the shape of the base it has not been possible to produce it as a casting so it is made up from
a series of laser cut laminations. These have most of the holes already formed so it is quite simple to bolt it together
with a few spacers to for a rigid construction. The pulleys due to their slim design are also laser cut fabrications.
The drive to the crankshaft is by horizontal steeple motion which makes for a fascinating engine to watch when in
motion.
The design was serialised in Engineering in Miniature in late 2007 to early 2008.
35 A4 drawings are supplied with the castings and all are available from Polly Model Engineering.
Woodroffe's "Verto" Engine 1880
Woodroffe and Co’s “Verto” engine was built at the
Albion works, Rugeley, Staffordshire in the 1880s and
90s. It was available in a range of sizes from 1 to 5 horse
power. It was a general purpose engine used as a power
source in many industries. It came in three forms, as an
engine on its own (below), as engine and boiler mounted
on a fixed base, which also doubled as a water tank, and
as an engine and boiler mounted on a travelling base
(right).
The model is also available in the same three forms. The
model is quite small, the boiler being 9” (127mm) high,
the flywheel is 4” (102mm) diameter.
The engine is shown with a boiler feed pump (above). But due to
the smallness of the set up. If continuous running on steam was
desired it would be better to disconnect the pump and feed the
boiler from a separate water supply.
The wheels are interesting, full size the spokes were built up
from strip material. A similar method is used for the model.
Gunmetal castings are available for the base, engine column,
engine base and cylinder. The flywheel is cast iron. The rest of
the engine is made from bar material. There are 46 A4 drawings
in the set giving details of all three forms of the engine. Both
metric and imperial dimensions are shown on the drawings.
The model was built on a Myford ML7R lathe. A milling
machine will also be found very useful in building this engine.
The model was serialised in EIM from September 2000 to July
2001.

Ferrabee’s Pillar Engine 1862
New October 2016
I was looking through some old technical
books and came across an engine
exhibited at the International Exhibition
of 1862 (not to be confused with the
Great Exhibition of 1851). I rather liked
the look of it so decided to make a
model. It was built by a company called
Ferrabee. It was founded in 1818 by
John Ferrabee at the Phoenix Ironworks,
Stroud, Gloucestershire. Later being run
by his sons James and Henry. It later
became George Waller and Co. They
produced cloth making machiner, water
wheels, agricultural machinery and
steam engines.
In 1830 they made the first grass cutting
machine, the invention of a local
mechanic Edwin Budding.
The frame for the engine is a hollow
Tuscan column or pillar, the flywheel is in
the middle of the column supported on
bearings at the top of the column and
passing through a slot cut in the top of
the column.
The cylinder is bolted to the side of the
column and works onto an overhung
crank. There is a pump on the opposite
side of the column worked by an
eccentric on the crankshaft. The bottom
of the column is blanked off part way
down to form a condenser tank in the
base, into which the engine exhaust is
directed, though I very much doubt
anybody will want to run the model with
a working condenser.
I only had one engraving to work from, I decided on a flywheel of 200mm diameter which is
within the range of most model engineer’s lathes, I have no idea of the size of the prototype
engine, but imagine a flywheel of approximately 2 metres diameter, which gives a 1/10 scale.
Iron castings are available for the flywheel, entablature and base. Laser cut parts include
beads for the column, guide frame sides and front, rocker arm and pump hanger, eccentric
strap, governor arms, governor links, governor lever and throttle link. Polly Model
Engineering also supply the column.
A parts list is included, along with a full set of 33 drawings all A4 size, they have dual
dimensions in metric and imperial. The building of the model was described in Model
Engineer magazine.

5. Our Own Stationary Engine Kits
5.1 R&B Gas Engine
This is the biggest engine which we do, available with 12" flywheel as standard and optional second
flywheel or can be fitted with smaller 9" flywheels.
Size and Weight: 2 ¼” bore x 2 ¾” stroke, finished weight 60 lbs.
This is an open crank internal combustion engine of
robust proportions and is conservatively stressed with
large bearing areas. It is capable of hard work and is
suitable for driving workshop machinery, dynamos,
water pumps, etc. The governor if fitted can hold
speed within 5%.
The engine is based on typical designs of circa 19001930 and may be run on natural gas, butane or
propane. If fitted with a carburettor the engine will run
equally well on petrol (gasoline). Ignition is by coil and
battery but a magneto can be fitted if so desired.

5.2 Atmospheric Gas Engine (AGE)
The atmospheric gas engine is a copy of a model engine circa 1885 when it was designed and run off coal
gas with open flame ignition.
Engine size: Bore 1” Stroke 1” : Twin 5” diameter flywheels
It has a fascinating operating cycle. Briefly, as the piston
progresses down the bore a mixture of gas and air is drawn in;
ignition is provided by an external flame sucked though a port
halfway down the side of the cylinder. Then follows a half stroke
of power and exhausting.
Thus, as there is no compression, this is a true “atmospheric”
engine.
These days it is no longer possible to obtain coal gas for which
the engine was designed, however acetylene (welding gas) has
a similar wide ignition range and this engine runs well on it.
Butane and propane are also suitable, but as they have only a
relatively narrow ignition range, they are not so easy to use.

5.3 Scott Vacuum Engine (Flame Gulper)
A really practical kit with a comprehensive list of parts
and materials designed for ease of making, ideal for
beginners or as a quickie in the middle of longer term
projects.
This type of (hot air) engine, sometimes known as a
flame gulper or licker were produced in the latter part
of the 19th century with ratings from 1/20 th to 1/2HP.
One such engine is listed in the 1904/5 Bassett-Lowke
catalogue as the “Lowne” patent atmospheric engine.
The engine works by drawing hot gases from a flame
via a valve into the cylinder as the piston descends.
Near the bottom of the stroke the valve shuts, the hot
gases condense and produce a vacuum. Atmospheric
pressure on the underside of the piston pushes it up
causing the power stroke.
The engine is hopper water cooled and has a 1 5/16”
bore with a stroke of 2”. Construction is relatively simple and fairly quick to build. It can be made on a lathe
with a centre height of 2 5/8” (65mm) or over. Castings are all cast ironl and ball bearings are used in the
big end, cam followers and main bearings. It runs well from cold but it is quicker if warm water is used in
the jacket. The power output is quite high for an engine of this type and it may be used to drive pumps,
dynamos or Meccano models. Speed can effectively be governed by the strength of the cam follower
spring as the follower tends to lift off the cam in a similar way to a hit and miss governor as used on gas
engines. Speed is also variable depending on flame setting and the cam timing.
The valve is made from carbon impregnated with graphite to withstand the flame temperature without
distortion. As the valve slowly wears, graphite is liberated in fine powder form which is sucked into the
cylinder subsequently lubricating the piston and bore.
Firing is usually by alcohol, but a gas burner can be fabricated and a rechargeable gas tank is available.
The kit includes castings, drawings, materials, ball races, special carbon/graphite valve material, springs
and screws. Drawings for the alcohol and gas burners are provided but no burner materials.

model. Simply controlled by throttling the water output.
Locomotive and Traction Engine Nameplates and Numberplates
We regularly produce machined nameplates for our Polly locomotive customers and
these nameplates can be made in sizes to suit other narrow gauge models in 5” and
7 ¼” gauge or to suit traction engines. The thickness of the brass plate used, gives
the impression of a substantial cast plate, something which cannot be achieved with
an etched plate. We are also able to supply some cast numberplates for GWR
locomotives and some other plates. Please enquire with your requirements. Since
plates are made to order, there may be a significant lead time.

10. Fittings
Polly Model Engineering and Bruce Engineering are famous throughout the world for supply of high quality
injectors and other steam fittings. Many of these items are craftsman made to the highest standards
achievable. Indeed many customers request products from particular craftsmen. Whilst we attempt to
maintain stocks of such items and are always developing new products and seeking new suppliers, delays
in shipment are sometimes inevitable if customers have very specific requirements. Due to the different
sources of supply fittings may vary in appearance and differ from those illustrated. If customers require
matching fittings, it is advisable to order them as a set. In some cases, we may be able to supply matching
handles for different styles of valve. Some specialist fittings are available for models in the Practical Scale
range. In particular a wide range of GWR fittings, as diverse as fine scale handrail stanchions and driver’s
seat castings are available.

Boilers, Boiler kits and Flanged Plates
We are currently unable to directly supply boilers or boiler kits. However, for our own designs of locomotive
we can normally make recommendations of suitable professional boiler makers.
Please bear in mind that demand for boiler making is high and lead times are correspondingly long. Place
your order sufficiently early to ensure your boiler is ready when you need it.

Nuts. Bolts, Caphead Bolts, Grubscrews
We stock a wide range of BA fastenings in popular sizes with hexagon (inc. small head), roundhead and
countersunk heads. A limited range of cap head (socket head or allen screws) bolts, BA and metric
studding is stocked in brass, steel and stainless steel studding. With the general adoption of metric
fasteners for industrial application, it is becoming increasingly difficult and expensive to obtain BA fasteners.
Although it is our intention to stock BA fasteners for as long as they are obtainable and there is customer
demand, we have for some time stocked a range of metric fasteners. The drawback of metric fasteners in
the small sizes has historically been the large size of the hexagon heads which made them generally
unsuitable for model use. We are pleased now to be able to offer a range of metric fasteners, specially
manufactured for model engineers. The small size hexagons are most appropriate for our models and a
wide range of special screws, including slotless ‘rivet head’ screws, dome nuts, etc., are available.
See tables on following pages for available sizes.

N.B. All our stock ‘bolts’ are technically screws, as they are threaded right up to the head.
Generally small BA and metric bolts are very difficult to source and many model engineers wrongly
assume that hexagon headed screws are in fact bolts, expecting screws to have slotted heads!

Metric Screws and nuts, specially produced for model engineers. High quality
rolled threads, with small size hexagon (choice of standard or high head bolts).
These nuts and bolts are precision made fasteners specially made in Germany for
model engineers. They should not be confused with lower cost industrial fasteners
which do not offer such clean hexagons or inferior machined thread screws of
doubtful strength.
Packs are marked with size of the bolts – e.g. M3 x 15, indicating the thread size and the length in mm.

Silver Solder
We have always sought to supply the highest quality silver
solders available, including the most popular Easyflo 2 from
Johnson Matthey. During 2010, EF2 was discontinued.
AG303 also a cadmium bearing alloy having a similar
temperature range to EF2 is also discontinued. Silverflo 24,
Silverflo 40 and Silverflo 55 rods are stocked, with SF55
being the closest substitute for EF2. Fluxes stocked, Easyflo,
Tenacity 4A and Stainless flux. Argobraze 56 is a special
silver solder particularly suited for stainless steel in arduous
environments such as superheater headers, where EF2 or
similar may fail after a time.

Stainless steel springs
in a variety of diameters and wire gauges, to give spring rates suitable for safety valves,
axlebox springs etc. Table below gives sizes and spring rate (lbs per inch of deflection).
Use the table below to determine the spring required. The first four columns give the
physical size of the spring and enable you to determine whether the spring will fit in its
intended place. The fifth column gives the force in pounds per inch deflection. It is thus
easy to assess what the force exerted by the spring will be and what the effect of further
deflections will be. Clearly when considering compressed springs care has to be taken
that the spring does not become ‘coil bound’.
Available in 1 ft lengths (305mm).

12. Books
We stock a wide range of model engineering related books, including many classics. ‘The Model
Engineer’s Reference Book’ is a must for every model engineer. Martin Evan’s Treatise on Miniature
Locomotive Construction is a valuable reference book for loco builders and the various books on building
Stuart stationary engines are essential to novice builders of those models. George Thomas’ work on
toolmaking is legendary and even for those who ‘want to get on with the job’ the books are worth reading.
Take time to peruse our collection of books at the major exhibitions where space allows us to display them.

16. Practical Scale
The fine scale range of locomotive designs offered by Polly Model Engineering. These designs
should not be confused with the well known locomotive kits. Designs are exclusive to Polly and
include models in the popular scales of 3 ½”, 5” and 7 ¼” gauge.
The general aim of Practical Scale has been to provide designs suitable for the 21st Century
where aspirations for fine scale models are very high, but experience, skill and facilities are not
always available. Designs are produced by reputable designers with the majority being published
in the model engineering press. We specialise in GWR designs, but the range includes locos
from other railways, including SR, HR and MR. We offer a number of GWR standard parts also
suitable for designs other than those listed. Wheel castings etc for other designs are also
available, please enquire.
The most well known of our designs is Penrhos Grange in 5” gauge, designed by Neville Evans
and although an impressive GWR 4-6-0, this loco is relatively simple to build. In addition to the
drawings and castings which might normally be supplied, there are a wide range of lost wax
castings, laser cut parts and some machined parts available. The aim has been to produce a
model of fine scale appearance with practical simplifications in those less visible areas. Subject
to availability, machined cylinders and other parts may be available for builders lacking facility,
time or skill. The tender designed for the Grange is applicable to many other GWR locos and
building is greatly facilitated by the availability of CNC profiled, drilled and formed platework. This
combined with the high quality castings, laser cut frames etc considerably reduces the work
involved in building a high quality model. In addition to the Collett tenders in 3500 and 4000
gallon form, we have the 3500 gallon Churchward model designed by Ian Roberts, again with the
CNC cut platework. The 7 ¼” Churchward tender designed in collaboration with David Aitken
takes modelling to new standards
The Highland locos again by Neville Evans are proven designs with several models having been
displayed in national exhibitions in recent years. These models are slightly more conventional in
the expectations of skill from the builder, but nonetheless a range of lost wax castings, laser cut
parts etc is available. Several examples of the Schools loco in 5” gauge have been completed
and this powerful 4-4-0 is ideal for those SR enthusiasts wanting to build a genuine 3 cylinder
version. The latest of Neville’s designs the Fair Rosamund GWR 0-4-2T in 5” gauge is an
attractive reasonably easy to build small tank engine. As at the time of writing (Jan 2011) the first
model was nearing completion.
The 3 ½” gauge SR Q1 is a simple model for those wanting to build a scale model without the
need for a large number of expensive castings. Although much simplified the model captures the
character of the prototype and laser cut profiles are available to realise the shape of the boiler and
firebox cladding.
Pete Rich’s fine scale drawings include a wealth of detail enabling the more discriminating
modeller to faithfully replicate in miniature a number of GWR designs. The principal designs are
the Castle/Star, the Saint and the Dean Single/Armstrong 4-4-0. The standardisation of GWR
designs is such that a number of other designs can be built and some additional drawings are
available. Most of Pete’s drawings are for 5” gauge.
For 7 ¼” gauge we offer the Collett Goods 0-6-0 tender loco, which is a very finely scaled model
serialised in EIM. A vast range of parts is available, including a number of machined and part
machined parts. Also in 7 ¼” we have drawings and parts for the production of a fine scale GWR
1400 class loco designed to similar standards.

17. Standard GWR Parts for 5” and 7 ¼” gauge
Polly Model Engineering has long been involved in the design and development of finescale GWR
locomotives and many of the ‘standard’ GWR parts are applicable to other models. Illustrated in
this section you will find some of these items.
17, 1 GWR Buffers
17.1.1 Parallel Buffers 5” & 7 ¼” gauge
Applicable to later GWR and BR era locomotives, these
buffers are supplied as assembled, working spring buffers.
The heads are CNC profiled to the correct shape and the
design is such that there is no
projection of the buffer shank
through the buffer beam when
compressed. A large spigot on the
backplate engages in the buffer plate to provide positive location.
5” buffers £49.50 pr, 7 ¼” gauge £59.50 pr
Lost wax cast step plates are available to complete (£9.95 pr 5” & £12.40 pr 7 ¼” gauge).
17.1.2 Taper Buffers (Collett) 5 “ gauge
These buffers shown on many Collett works drawings are available
as a set of lost wax castings and CNC turned parts. The step plate
is cast into the stock. As with the parallel buffers there is no
projection of the buffer shank through the buffer plate. Complete set
of parts £65.90 per pair.
Collett Taper Buffer
17.1.3 Taper Buffers (Dean) 5” gauge
These more slender type buffers are fitted to earlier locos. Lost wax castings for buffer stocks to
suit Pete Rich designs such as the Dean Single are available - £9.25 each.
17.2. GWR Handrail Stanchions 5” and 7 ¼” gauge
We produce a comprehensive range of handrail stanchions based upon the profiles shown on the
Swindon drawing. In addition to the standard pillars, the special front smokebox door type is
produced and available singly. The short type as used on tenders and pannier tanks, etc are
available blind as well as through type. See hand rail stanchions P40.

17.3. GWR Injector Steam Valves
A pair of these distinctive valves on the turret of any GWR
engine sets it apart from the model with standard proprietary
valves. Valves for both gauges are fitted with Tufnol handles
5” gauge (1/4” x 40 tpi)
£28.50 each
7 ¼” gauge (9/32”x 40 or 5/16” x 32 tpi) £43 each
17.4. GWR Cylinder Relief Valve
A prominent feature of outside cylinder GWR locos, these working valves are
scaled from the full size.
5” gauge threaded ¼ x 40 tpi £15.50 each
7¼” £22.00 each
17.5 GWR Plunger type Cylinder Draincocks
Available for 5” and 7 ¼” gauge
5” gauge set of 3 £40 (illustrated) 3/16 x 40
7 ¼” gauge set of 3 £60 threaded 3/16 x 40
7 ¼” gauge available right angled or 30 degree type.
17.6 GWR Loco Wheels
Standardisation on the GWR meant that wheels for a wide variety of classes of locomotive could
be interchanged. For example, the 5’ 8” wheel used on the Grange, was in fact the wheel
previously used on the Moguls and similar wheels were used on the large prairie locos, Manors
and on 47xx class. Thus the wheel we produce for Penrhos Grange has potential for many other
models The Fair Rosamund (late version) trailing wheel casting is in fact the same as the trailing
wheel on the large prairie and with the leading wheel being similar to a bogie wheel a full set of
wheels for a 41/51/61 prairie is available. The early Castle wheel is again the same as the early
4-4-0 County wheel and so it goes on. In many cases wheel designs changed over the years,
particularly in respect of strengthened wheels with crankpins on a web between the spokes. For
Hall and Modified Hall we can provide both styles.
We have a wide range of patterns available for many standard GWR wheels in both 5” gauge and
7 ¼ gauge and further wheels are added as the months go by. So even if we do not list the model
you are considering, enquire as to how we can help. We have recently produced new patterns for
7 ¼ gauge bogie wheels, both 3’ and 3’2” sizes and the
driving & coupled wheels for the GWR 2-8-0 heavy
freight locos & wheels for both 57 and 94 panniers.

17.7 GWR Brake Valves
Brake valves are a distinctive feature of any loco backhead and the GWR had a
few standard styles. For some time, we have supplied a 5” gauge valve with
large ejector control suitable for Penrhos Grange etc. Currently we have valves
for 7 ¼” gauge under development. Whilst the
development of these valves has been triggered
by the need for the Collett Goods, the valve will
also be appropriate for other locos fitted with
loco steam brakes and vacuum train brakes. We
also intend to produce a GWR straight vacuum
brake valve in 7 ¼” gauge.
17.8 Cab Front Windows
GWR Cab front windows evolved quickly and even
though designs varied over the years from the
early 1900’s, all are recognisable as GWR style.
Very early windows (such as can be seen on Lode
Star in the NRM) are fitted with conventional door
type hinges, whereas some are fitted with top and
bottom pivots. However the
most elaborate are fitted
with fixed frame cast
windows with opening cast
frames and hinges built into
the frame.
We produce
windows to suit a variety of
classes of loco in all these styles for both 5” and 7 ¼” gauge locos. There
are some standard sizes which were fitted to a number of classes, but it
should be remembered that in building model cabs we invariably use
thicker than scale plate and this restricts the space available for window
frames. So although we can produce windows to the works drawings, it
may not be feasible to fit them to a particular model and some compromise
is necessary. Windows are normally supplied glazed with acrylic material and operating hinges
and handles.
17.9 GWR Standard Cab Side Windows
GWR cab side windows are fitted with blind bolts through the cabside
sandwiching the glazing between the frame and the cabside. Our windows in
5” and 7 ¼” gauge replicate this construction with the 7 ¼ gauge windows
closely corresponding to their full size counterparts. To avoid the risk of the
glazing ‘popping’ out, the design for the 5” gauge windows is modified such
that it is not visible on the assembled window, yet the glazing is more
positively retained.
17.10 Cab Seats
Cab seats as illustrated in the Grange cab above, provided little comfort in full size for the
driver/fireman but they do add to the appearance of a cab. Sets of lost wax castings available:
7 ¼ gauge - £32 and 5” gauge - £22 per seat including brackets.

17.12 CNC cut plate work for other models
As you will see throughout this catalogue, we produce a range of CNC cut and drilled brass
platework to suit the range of models which we supply. In addition we have developed platework
for a number of popular models not in our range. For example we can supply an extensive range
of platework to suit Martin Evans Torquay Manor, although we do not supply drawings and
castings for that model. Similarly, we are able to supply platework to suit GWR King in 5” and 7
¼” gauge together with tender tank parts for a comprehensive range of GWR tender types.

18. GWR “Penrhos Grange”
for 5” gauge Designed by Neville Evans
Penrhos Grange is recognised as the model which significantly
changed the perception of model engineering in the 21st
Century.. In the past committed craftsmen have built some
wonderful models but such models have been beyond the skill
of an average model engineer. Present day aspirations are
higher than ever, but skill levels may be more limited and this is
reflected in the popularity of kit-built locos. Penrhos Grange is
not a kit loco, and may be built in a conventional manner with
drawings and castings available. However, if required much
more can be available, as shown in the list below. Drill marked laser cut frames and other parts help to
quickly establish a square foundation for the loco. The option of machined cylinders and wheels often
appeals to builders with limited facilities, skills or time. The wide range of lost wax castings further reduce
skill and machining effort required to realise a fine scale model. The simplifications of such things as drag
beam construction are hard to discern from the finished model which bears a close resemblance to the
prototype. The availability of CNC cut, drilled and formed platework appeals not just to Grange customers
but to many other builders of GWR locomotives who realise how long it takes to get all the rivet holes in the
right place and ensure the many parts of a tender or cab fit together correctly.
The model has been described in Model Engineer, but care must be taken as the designer’s first intent was
to develop a Grange using available parts. The present design evolved during publication of the series.
For tender details see section 6.1 or 6.2.
All drawings are full size for 1 1/16” to one foot., Full set of loco drawings £80 inc vat.

20. Fair Rosamund GWR 0-4-2 tank loco
A new design in 5” gauge by Neville Evans
serialised in Model Engineer.
The first model of this attractive, early GWR 517 class tank loco has been built by Derek
Tulley, who successfully completed Neville’s School’s class loco in 2009. Although
Neville sadly died shortly before the model was completed, drawings for this design are
now fully available, completed from the working drawings provided by Neville. All major
castings are available, together with laser cut frames, buffer beams, motion plate, etc and
many of our standard GWR parts are suitable to complete this model.

22. GWR Loco Designs by Pete Rich
Pete Rich is a respected loco designer, having designed and built a number of award winning locomotives.
Numerous examples of his Castle and Star have been built. His Dean Single and Armstrong 4-4-0 design
is currently being serialised in Model Engineer. Pete’s drawings contain a wealth of historical information
regarding the prototype locomotives, their liveries and modifications. These designs are not for beginners
but the prototypical accuracy of the drawings should enable builders to achieve very high standards. The
availability of castings is developing in collaboration with Pete.
22.1 Saint 4-6-0
This is the foundation 2 cylinder design and the set of available drawings cover most details of the
locomotive. GA’s and frame plans for other 2 cylinder locomotives having common parts with the Saint are

23. GWR Tenders
Polly is renowned for the range of popular GWR tenders which we produce. Most tenders are available in
both 5” gauge and 7 ¼” gauge and with some popular 7 ¼” designs being in 1.5” to the foot, rather than the
fine scale 1.54” to the foot, we can supply tender tanks to both scales.
Designs available range from the later Dean tenders from the late 19th Century, through the most numerous
Churchward tenders, the various sizes of Collett flush bottom tenders to the final design of the Hawksworth
welded tank slab sided tender. We are thus in a position to supply tender parts and tank, for virtually any
popular great western design loco. Although we can supply parts for tender chasses, in many cases our
tender tanks can be supplied to fit to your own chassis if that has already been produced.
All tenders are designed to provide an accurate prototypical appearance, but necessarily the 5” tenders
involve some simplification of the internal structures, which in no way detracts from the appearance of the
finished tender. Our flush bottom tanks are generally simpler in construction than those with a longitudinal
sump between the frames and our 7 ¼” Churchward 3500 gallon tender is the most accurate and complex
or our models. For those wanting a simpler but prototypically accurate tender to run behind a Collett Goods
loco for example, the Collett 3000 gallon tender fits the bill.
GWR standardisation meant that tenders could be interchanged between locomotives, sometimes creating
unlikely pairings. For models, especially in 5” gauge, the choice of tender may to some extent be
influenced by practicality for driving. Lower tenders such as the Chruchward 3500 or the smaller Collett
flush bottom tenders are obviously easier to lean over for driving, but would clearly be inappropriate behind
a King where there is no alternative to the Collett 4000 gallon tender. Should you require any advice
regarding prototypical tender pairings, practicality for driving or complexity of the model, please do not
hesitate to contact us, scale@pollymodelengineering.co.uk
Chassis parts include laser cut frames, stretchers, drag beam, buffer beams and where appropriate
specialised bracket profiles. Wheel castings are fine sand castings based on full sized designs. Lost wax
castings enable us to produce smaller parts with a high degree of detail, requiring little finishing.
Tender tank are produced as sets of CNC cut and drilled parts, with our unique scoring of the brass
facilitating precision bending without any specialised facilities. The majority of GWR tenders had vast
number of snap head rivets, contributing much to the characteristic appearance of GWR locos from the first
World War onwards. Prior to this time, craftsmen in the works laboriously flushed off rivets. Our drilled
parts facilitate getting the rivets in the right place in clean straight lines and much reduce the time taken to
produce a fine scale model. Most of our tenders require very little if any angle in their construction, folded
flanges facilitating accurate assembly. Where appropriate, tender tanks include coal doors, toolboxes etc.
Tool boxes provided as scored flat parts, are easily folded to shape and parts are included to make the
hinges for lids.
Spun water scoop domes for the larger tanks and lost wax cast domes for the smaller tanks, together with a
range of castings for water gauges, vents, fire iron supports, etc, provide the finishing touches.

CNC cut drilled and formed platework
As described in Engineering in Miniature, designed in collaboration with David Aitken, this tender tank is no
doubt the finest scale model yet specified. The model design derives from works drawings and careful
study of surviving tenders, particularly those in the National Railway Museum. With our computer aided
design systems and CNC machines, we have gone to great lengths to take much of the tedious work out of
the project. All platework for the tank is CNC cut and precision drilled to ensure a good fit. Forming of the
corners and top flare are among the most challenging operations for the model engineer and our preformed sides eliminate this problem. In total there are some 10 000 rivet holes pre-drilled in the platework
and appropriate rivets can be supplied. A small amount of internal angle is required to complete the tank,
but external angles are supplied as CNC cut and scored components which fold to the precise dimensions.
Illustrations on this page show the tender built to run behind our 2251 Class Collett Goods
Complete set of CNC cut and drilled brass plate work - £1350
This includes parts for tool boxes, sand boxes, filler, shovelling plate, sides and coal space CNC formed
etc. Dome, vents, water gauge listed above can be used to complete the tank. Half round beading, rivets
and other materials also available.

23.5 GWR Collett
4000 gal Tenders
for 7 ¼ Gauge
A tender fit for a
King!
Following on from the success
of our other tenders and
particularly the CNC
cut/drilled/formed tender
tanks, we have developed a
tender tank to suit 7 ¼ gauge
models.
Drilling of thousands of holes in neat rows, precisely cutting platework with fits and neatly forming
flares and corners is one of the more tedious aspects of fine scale modelling. Our tender tanks do
not take all of the skill out of making fine scale models, but they do take a lot of the drudgery out
of the process. This enables skilled workers to more quickly produce high quality models and
gives those with less experience a very good start. The 4000 gallon tank kit is developed from
our experience of the 5” gauge version, but is more complete including parts for the shovelling
plate, fire iron rack, etc. In total there are approaching 100 pieces of cut/drilled brass. The sides
are cnc formed to ensure accuracy of the corner bends and flares. The other parts of the kit,
including coal doors, toolboxes, etc are scored for simple bending without specialist equipment,
but for those builders requiring it, we can form these parts for a small extra cost.
Price of tender tank brass parts including formed tender tank sides £1200 inc VAT.
Additional cost for bending other components £150
Other parts such as spun waterscoop dome available as per Churchward tender.
Tender chassis parts have a lot in common with the Churchward tenders, so wheels, horns, scoop
castings, etc can be utilised. In response to demand, we have recently introduced frame
components for the Collett tenders and these are listed on the next page (in common with the
3000 gallon tender).
King builders in particular may note that although we do not supply drawings for a King, we are
able undertake manufacture of platework parts to suit your requirements particularly for GWR
models. A number cab platework sets have already been delivered to customers, including
custom designed opening front windows, fire iron tunnel parts and glazed cab side windows.

23.6 GWR Collett 3000 gal Tenders
for 7 ¼ Gauge
A batch of flush bottomed 3000 gallon tenders were built to suit the 2251 Collett Goods locos
although as there were about three times as many locos as new tenders, the locos frequently ran
with older tenders (e.g. the 3500 Churchward design). Following on from our successful
production of the 4000 gallon tank for the King, we now introduce this 3000 gallon version, based
very much on works drawings and observations of surviving tenders. However, with these Collett
tenders we have deliberately simplified the out of sight tank bottom such that the soleplate and
tank bottom are flush. This is not visible from outside the tender and materially reduces the
complexity of assembly for the model engineer.
Since wheels, axleboxes, horns etc are common with other tenders, it is easy for the model
engineer to build a suitable chassis using our castings. We plan to produce specific laser cut
frames in the near future such that everything for this tender will be available from Polly.

23.7 GWR Hawksworth 4000 gal Tenders
To complete the range of popular GWR tenders, we have in preparation the Hawksworth 4000
gallon tender as would commonly run with Modified Hall locos and sometimes castles and
Halls.
Initially we are producing drawings for a 5” gauge version and if there is sufficient interest we may
produce a 7 ¼ gauge design. The design is derived from Swindon drawings of which we have a
large number and reference to surviving prototypes such as the example shown above behind
6998 Burton Agnes Hall at Didcot.
Many of the castings of the Hawksworth tender are common with the other tenders, including
wheels, axlboxes, horns, etc. Laser cut frames with the distinctive cut outs will be available
together with a comprehensive set of brass parts for the tank. The tank of the prototype is of
course a fully welded structure, but the model is assembled with a modest number of screw
fixings prior to soft soldering. The screw fixings are flushed off prior to finishing to create the
impressive plain sides of this large tender.

24. GWR 2251 Class 0-6-0 Collett Goods 7 ¼” gauge
Designed by David Aitken
This fine scale 7 ¼” gauge loco has been designed with reference to the Swindon works drawings and
close examination of the surviving prototype 3205 on the South Devon Railway.
Serialisation of the construction of the loco commenced in Engineering in Miniature (September 2006) and
our model shown above was awarded a First Certificate at the Doncaster National Model Engineering and
Model Show in May 2016. In order to facilitate fast build of this loco, many laser cut, lost wax cast and CNC
machined parts are available. Whilst drawings, castings and most parts are normally available, availability
of machined parts cannot be guaranteed.

28. 5” gauge “STOWE”
SR Schools Class 4-4-0
Designed by Neville Evans
Derek’s Schools loco
on display at Bristol
2009
This design by Neville Evans has been serialised in Model Engineer. Several completed models are now
running with a number of others being built. As a powerful 3 cylinder locomotive in a compact outline (the
full size locos having been designed to cope with the restricted loading gauge), the complexity of this model
makes it more suitable for the experienced model engineer. Builders are encouraged to refer to the articles
in Model Engineer for further detail of the construction, particularly that of the tender.
All drawings are full size for 1 1/16” to one foot.

29. Bulleid Q1 in 3 ½” Gauge
Recently serialized in Model
Engineer, this simplified design by
Nick Feast, of the well-known S R
loco has already proved itself over
the last couple of years on the
Bournemouth track. Castings and
laser cut parts are available to start
building this loco now. The
characteristic Bulleid wheels and the
shape of the boiler cladding are
easily produced.
The model is easy to build with
basic workshop facilities and due to
its size is easily handled.
Publication of this model commenced in June 2009
in Model Engineer. A full set of drawings is
available. The designer has completed one model
and is building a second from his own plans. In
due course, as the drawings are amended, revised
sheets will be issued. The following basic parts are
available and builders may well fabricate other
parts themselves. Further parts are expected to be
added to the list over coming months. Please
enquire for boilers and boiler fittings and other stock components.

30. Designs by Ken Swan
Polly is pleased to be officially appointed to distribute drawings and castings for the popular
proven designs of Ken Swan. The models are based on well known narrow gauge prototypes and
Ken’s drawings are renowned for their accuracy. As agreement has only just been reached with
Ken for the distribution of these designs, prices are yet to be defined. Such is our enthusiasm for
Ken’s 0-6-0 Koppel, our MD Andy Clarke is building one for himself. This may well mean that
rather more laser cut and machined parts can be made available if there is a sufficient demand.
30.1 Wren
This delightful small 0-4-0
tank engine is relatively
simple to build, yet
sufficiently powerful to be
welcome on most 7 ¼”
gauge railways.
A set of 29 large format
drawings is available - £135
or individual sheets £10 ea.
Availability of castings, laser
cut parts, etc will be added
as they become available.
Forty original Kerr Stuart drawings have been used as guidance in designing this
model which is to a scale of 3 ¾” to the foot.
Externally, the model is almost an exact copy of the prototype with the absolute
minimum of modeller’s licence. Internally, some changes have had to be made
to simplify moulding and machining problems, also to allow the model to be a
successful working steamer capable of withstanding hard and heavy work on the
track.
One of the prototypes (Works No. 4328 was fitted with a crosshead driven feed
pump, this valuable operating feature is incorporated into the model.
Although being almost 1/3rd full size, the size and weight of this model is very
modest and should not prove too difficult to load and transport in the average
estate type of family car.

30.2 0-4-0 Rack Koppel
This unusual model,
incorporates a working
pinion drive which
engages in a rack
between the tracks,
enabling the loco to
cope with severe
gradients. Ken’s rack
0-4-0 Koppel with its
counter-rotating
flywheel is well known
and models can be seen
in operation on the
miniature cog railway at
Beamish museum. The
cog loco shares a lot of
components with the
more conventional
adhesion locos.
The picture to the right shows Ken’s
own model on the Beamish Cog
Railway.
A set of drawings for the model
comprises 22 large format sheets is
available. Castings and specialised
material for the model will be made
available shortly and added to this
catalogue.

30.5 Six Coupled Koppel 7 ¼ Gauge
The O-6-0 adhesion Koppel was partly serialised in Engineering in Miniature, but it was not
possible for the series to be completed. Working with an enthusiastic builder and with Ken’s
support, Polly has completed the development.
Ken’s model is a fine scale model of the simplified 0-6-0 Koppel which we produce as a 5” gauge
kit loco.
The SIX Coupled Koppel is based on a standard Orenstein and Koppel 20 HP well tank
locomotive which first appeared in 1899 carrying the works plate 513. The design continued to be
manufactured with a few detailed differences until works number 12669 was turned out in 1935. It
is believed that 45 out of the 65 0-6-0 locomotives were built with Walschaerts valve motion - the
valve gear chosen for the model
During the 0-6-0 production period over 600 0-4-0 Koppels were produced. They had the same
hauling capacity as the six coupled 20 HP locomotive being identical in all other ways. Wheel
configuration was a question of economics for the owners. If the permanent way was short, the
cost of heavier section rail was more acceptable and a cheaper 0-4-0 locomotive was purchased.
Outwardly there are significant differences between the Rack and Six Coupled Adhesion
locomotive, but true to Orenstein and Koppel’s approach, both models use the same tried and
tested cylinder, wheel, valve and boiler components. Ken Swan’s own locomotive has been
passenger hauling on the Beamish Model Engineers Group site at Beamish for over 24 years and
does so to this day.
Working in collaboration with Polly Model Engineering Walter Ogden, member of the Hereford and
Bristol Societies of Model Engineers, is building the first model. Having constructed a prize
winning rack Koppel version of Ken Swan’s design he was very impressed by the locomotive and
decided make this his next project. Polly Model Engineering will make available a range of laser
cut parts for the frames and superstructure, in addition to the castings and specialized parts and
drawings.

31. Designs by D.A.G.Brown
Polly is pleased to have been appointed exclusive distributor for Anna, a well proven design
published by Derek Brown in the Model Engineer Magazine.
31.1 Manning Wardle Locomotive Anna
This model, in 7 ¼ in. gauge, was described in 24 issues of Model Engineer starting in April
2004 and finishing in February 2006. A further 10 issues from July 2007 to April 2008 dealt
with the construction of the prototype model in D A G Brown’s workshop and highlighted the
solutions to some of the more difficult problems encountered.
For the benefit of would-be constructors, a couple of hundred photographs of the construction
process are freely available on a CD (for good resolution). A set of 35 drawings from CAD
drawings to a very high standard form the start of the building process; these are mainly on A2
paper size, which renders them much clearer than the published versions. All known errors
have been eliminated during the process of building the original and in liaison with others
during their labours. Almost all of these have been quite trivial and many are merely a matter
of clarification.
A set of 71 castings is available, as are a couple of hundred laser-cut components in both mild
steel and 12% chrome steel; these make life a whole lot simpler when it comes to sourcing
suitable material and accuracy is guaranteed. In the list these are grouped into manageable lots
or sets for particular sections of the build. In addition, stocks are kept of piston rings, springs
of all types, firebox spun bezels and wire-cut expansion links and die blocks in gauge plate.
For those who do not wish to build their own boilers, we have a liaison with a couple of
reputable trade boiler builders, both of whom have taken orders from current constructors
