HEALTH & SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that
you, as the user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and
understood this manual.
Most important you must know how to safely start and stop this machine, especially in an
emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the machine
during use will reduce your concentration. Mess on the floor creates a trip hazard. Any
liquid spilt on the floor could result in you slipping.
Find a suitable location. If the machine is bench mounted; the location should provide good
natural light or artificial lighting as a replacement. Avoid damp and dust locations as it will
have a negative effect on the machine’s performance.
If the machine is portable; do not expose the tool to rain. In all cases do not operate power
tools near any flammable materials.
Beware of electric shock. Avoid contact with earthed surfaces; because they can conduct
electricity if there is an electrical fault with the power tool. Always protect the power cable
and route it away from danger.
Keep bystanders away. Children, onlookers and passers by must be restricted from entering
the work area for their own protection. The barrier must extend a suitable distance from the
tool user.
Unplug and house all power tools that are not in use. A power tool should never be left
unattended while connected to the power supply. They must be housed in a suitable
location, away locked up and from children.
Do not overload or misuse the tool. All tools are designed for a purpose and are limited to
what they are capable of doing. Do not attempt to use a power tool (or adapt it in any way)
for an application it is not designed for. Select a tool appropriate for the size of the job.
Overloading a tool will result in tool failure and user injury: This covers the use of
accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous because they can
become entangled in moving machinery: This can also result in parts of body being pulled
into the machine.
Clothing should be close fitted, with any long hair tired back and jewellery and neck ties
removed. Footwear must be fully enclosed and have a nonslip sole.
6
5.
HEALTH & SAFETY INFORMATION
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can all be
dangerous if not suitably protected against. If the work involving the power tool creates dust
or fumes; wear a dust mask. Vibration to the hand, caused by operating some tools for
longer periods must be protected against. Wear vibration reducing gloves and allow long
breaks between uses. Protect against dust and swarf by wearing approved safety goggles or
a face shield. These are some of the more common hazards and preventions; however,
always find out what hazards are associated with the machine/work process and wear the
most suitable protective equipment available.
Do not breathe contaminated air. If the work creates dust or fumes; connect the machine (if
possible) to an extraction system either locally or remotely. Working outdoors can also help
if possible.
Move the machine as instructed. If the machine is hand held, do not carry it by the power
supply cable. If the product is heavy; employ a second or third person to help move it safely
or use a mechanical device. Always refer to the instructions for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance and you
falling. This could be from a height or onto a machine and will result in injury.
Maintain your tools correctly. A well maintained tool will do the job safely. Replace any
damaged or missing parts immediately with original parts from the manufacturer. As
applicable; keep blades sharp; moving parts clean, oiled or greased; handles clean; and
emergency devices working.
Wait for the machine to stop. Unless the machine is fitted with a safety brake; some parts
may continue to move due to momentum. Wait for all parts to stop; then unplug it from the
power supply before making any adjustments, carrying out maintenance operations or just
finishing using the tool.
Remove and check setting tools. Some machinery requires the use of additional tools or keys
to set, load or adjust the power tool. Before starting the power tool always check to make
certain they have been removed and are safely away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power supply, make
sure the switch is in the OFF position. If the machine is portable; do not hold the machine
near the switch and take care when putting the machine down; that nothing can operate the
switch.
Carefully select an extension lead. Some machines are not suitable for use with extension
leads. If the tool is designed for use outdoors; use an extension lead also suitable for that
environment. When using an extended lead, select one capable of handling the current
(amps) drawn by the machine in use. Fully extend the lead regardless of the distance
between the power supply and the tool. Excess current (amps) and a coiled extension lead
will both cause the cable to heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never operate a
power tool if you are under the influence of drugs (prescription or otherwise), including
alcohol or if you are feeling tired. Being disorientated will result in an accident.

10. BASIC WOOD TURNING
The following pages of this manual explain and illustrate
the correct use of the turning tools, the tool rest and
other information to help you.
FIG.7
10.1 SPINDLE TURNING - FIGS. 7 - 10
Select a piece of wood 50x50x300mm (approx.) Draw
diagonal lines on each end the piece of wood to locate
the centres (Fig.7).
In both ends of the piece of wood drill a 1.5mm hole,
7mm deep into the centre. Now secure the workpiece in a
soft jaw vice. Put the point of the drive spur into the
drilled hole and tap the spur in securely (Fig.8).
Now remove the spur and check the prongs have left an
imprint.
Ensure that both the drive spur and live centre are clean
and insert them into the lathe (see page 7). Place the
workpiece between the centres and close up the tailstock
(Fig.9) making sure the marked end goes the tailstock
end.
Select the required tool rest position approx 3mm away
from the corners of the wood and 3mm above the centre
line (Fig.10) and lock the tool rest into position. Now
select the appropriate speed (see Page 8), rotate the
workpiece to check the corners do not foul the tool rest.

10.2 USING WOODWORKING CHISELS - FIG. 11
Professional woodturning chisels have handles
approximately 250mm long. This provides the operator
with good grip and leverage. A sharp chisel will be much
easier to work with and will give the job a cleaner finish.

10.3 THE THEORY OF TURNING - FIGS. 12 - 13
There are two types of turning chisel. These are:
1. Those intended primarily for cutting,
2. Those used only for scraping.
The cutting chisels are the gouge, skew and parting type.
These are sharpened to a razor edge by honing on both
sides.
The scraping chisels are the flat nose, round nose and
spear point. These are not honed on the flat sides - the
wire edges produced by scraping are left on to aid in the
scraping process (Fig.12). Shows the two types of chisel.
CUTTING AND SCRAPING:
To make a cut, the chisel should be held so that the sharp
edge actually digs into the revolving workpiece, shavings
should now peel off. To scrape, the chisel should be held
at a right angle to the surface of the workpiece, fine
pieces of wood will be produced when scraping instead
of shavings (Fig.13).
Many operations require the cutting chisel to be used for
scraping but scraping chisels are very rarely used for
cutting. Scraping will blunt/dull a chisel much faster
especially when using razor sharp cutting chisels.
Cutting is much faster than scraping and produces a much
smoother finish. Cutting is more difficult than scraping,
but scraping is more precise and easier to control.
14
FIG.12
FIG.13
10. BASIC WOOD TURNING
10.4 KNOWING WHEN TO CUT AND WHEN TO
SCRAPE - FIG. 14
There are two different approaches to the work when
turning. The first is towards a circumference of the
workpiece (eg. When turning down the outer surface of a
cylinder or the inner wall of a hollow round box). Using
this method, the surface being turned travels under the
edge of the chisel like an endless belt. The second
approach is towards the diameter of the workpiece (as
when turning the face when faceplate turning, or the side
of a large shoulder when spindle turning) using this
method the surface being turned rotates like a disc under
the chisel edge. Some jobs will require both methods
being used (Fig.14).
Either a cutting or scraping action may be used when the
method used is towards the circumference – the shaving
will come off like the peel from a potato.
Only scraping can be used when the method used is
towards the diameter. The reason for this is obvious when
you consider that faceplate turning nearly always requires
the removal of wood across the grain. Wood does not
peel easily when turning across the grain and any attempt
made to use cutting methods will probably result in
damage to the workpiece and the chisel being thrown by
the workpiece.
It therefore follows that a cutting action is used for
general spindle turning operations, while the majority of
faceplate turning is carried out by the scraping method.
When both methods are to be used, you will have to
judge by the feel of the workpiece when to stop cutting
and start scraping. NEVER try to cut when it becomes
difficult to hold the chisel against the wood grain.

10. BASIC WOOD TURNING
10.5 POSITIONING THE TOOL REST FOR
CIRCUMFERENCE TURNING - FIGS 15 - 20
When turning, the object is to pierce the outer surface of
the wood to a desired depth, then to hold the chisel
steady with the bevel edge parallel to the work
circumference, so that the chisel will peel off a shaving at
this desired depth. The only sure method of holding the
chisel steady is to rest the bevel against the workpiece,
the tool rest will act as a fulcrum to support the chisel
against the downward force of the revolving workpiece
(Fig.15).
If the tool rest is positioned too low, so that the chisel
bevel is held out from the workpiece, (Fig.16) the cutting
edge of the chisel will continue to dig deeper into the
workpiece until the “bite” becomes so deep that you
have difficulty holding the chisel, then the chisel will
begin to bounce or chatter against the workpiece.
If the tool rest is positioned too low, the chisel will be
held extremely high to position the bevel of the chisel
against the workpiece (Fig.17) then the tool rest will lose
its value as a fulcrum and the downward force of the
revolving workpiece will kick the chisel back and possibly
out of your hands.
If the tool rest is positioned too high and the chisel is
correctly positioned for cutting it will strike near the top
of the workpiece where the direction of the force exerted
by the workpiece is almost horizontal and will again
result in kickback (Fig.18).

10. BASIC WOOD TURNING
If the tool rest is positioned too far away from the
workpiece as shown in (Fig.19), the chisel, when correctly
held will again be too high on the workpiece. You will also
find that you have less leverage on your side of the tool
rest and it will be very difficult to hold the chisel.
With a large diameter workpiece, the tool rest can be
above the workpiece centre line and further out from the
surface of the workpiece than normal (Fig.20).
With a small diameter workpiece, the tool rest should be
closer to the surface workpiece than normal. As the
workpiece gets smaller the rest should be repositioned
(Fig.21).
10.6 POSITIONING THE TOOL REST FOR
CIRCUMFERENCE SCRAPING - FIGS. 21 - 24
When scraping, the position of the tool is not as critical as
it is for cutting operations. The chisel is normally held
horizontally, although it can be held at an angle to reach
difficult places. The wire edge of the chisel does the
scraping. Fig.22 and 24 show the result of a chisel being
too low or too high. Fig.23 shows the chisel positioned
correctly on the tool rest.

10.7 POSITIONING CHISEL AND TOOL REST FOR
DIAMETER SCRAPING - FIGS. 25 - 26
When diameter scraping, the area to the right of the centre
is moving upward (Fig.25). If the chisel is placed in this area
it will simply be carried up and off the tool rest, possibly
out of your hands. So all diameter approach operations
MUST be done at the left of the centre.
Three different chisel contact points are shown (Fig.26).
Note that when the chisel is positioned above or below the
workpiece centre, the work surface sweeps past the chisel
edge at an angle and will tend to carry the chisel in one
direction along the tool rest.
Only when the chisel contacts the workpiece centre line
does the workpiece pass squarely under the edge of the
chisel. This then is the position in which it is easiest to hold
the chisel steady. To obtain the position place the rest
approximately 3mm below the centre.

10.8 USING THE GOUGE CHISEL - FIGS. 27 - 28
Three gouges 6, 12, 18mm sizes are usually sufficient for
home workshop turning, but other sizes are available (refer
to Draper Catalogue). A gouge chisel is normally used for
rough circumference turning or turning raw stock down to
a cylinder of workable size. It is best used for rapid removal
of the workpiece, but will not produce such a smooth
finish, but with practice it can be used for cutting coves, for
shaping long cuts and is also useful for scraping.
When used for cutting, the gouge is always held with the
convex side down and should be rolled approximately 30°
to 45° in the direction in which it is being advanced along
the rest, the cutting edge would be a little in advance of
the handle, Figs. 27 & 28.

10. BASIC WOOD TURNING
10.9 USING A SKEW CHISEL - FIGS. 29 - 32
Two skew chisels 12, 25mm are all that are required for
general use although other sizes are available (refer to
Draper Catalogue). This chisel is used mostly for making
finished cuts, to cut vees and beads and square shoulders.
When correctly used, it will produce the best finish that
can be obtained with a chisel. It should not be used for
scraping as this will quickly dull it.
For finish cutting, the skew should be held with the
cutting edge considerably in advance of the handle and
should be bevel against the work. Good practice is to
place the skew well over the workpiece and pull it back
until the edge begins to cut; then swing the handle into
position to advance the cut. Both the toe and the heel of
the skew can be used for making light cuts; but do not
penetrate the wood too deeply without cutting clearances
as you may burn the tip of the tool. Refer to Figs.29, 30,
31, 32 & 33.

10. BASIC WOOD TURNING
10.10 USING A PARTING CHISEL - FIGS. 34 - 35
FIG.34
A parting chisel has one primary purpose - to cut straight
into the workpiece as deep as desired, or all the way
through the workpiece to make a cut off. This is a very
narrow chisel, approximately 3mm wide and is shaped to
cut its own clearance, so the cutting edge will not burn.
But when used as a scraper, it should be backed off at
regular intervals to prevent overheating. See Fig.34, 35.
FIG.35
10.11 USING SCRAPING CHISELS - FIGS. 36 - 38
Finally, three more types of chisel should complete the list
of chisels for the average craftsman, these are 12mm
spear point, 12mm round nose and 26mm flat nose. Each
of these chisels may be purchased in various sizes, (refer to
the Draper Catalogue) for special jobs. All of these are
very useful for diameter scraping (see Figs.36, 37, 38)
operations and for circumference scraping when cutting
methods cannot be employed.
The spear point chisel is used for fine scraping and
delicate operations such as the forming of beads, parallel
grooves and shallow vees. Edges and bowl contours can
be rounded with the round nose chisel. Any flat surface
can be scraped with the flat nose chisel.
