INSTRUCTIONS FOR UNCRATING AND SETTING UP A SHELDON LATHE
All Sheldon Lathes come completely assembled, tightened up, and ready to be placed on the floor, oiled, and put to
work. They come crated with bench legs, floor legs or pedestal base, and motor drives (if any) attached, with all
machined and hand scraped parts protected with rust preventative, un-machined parts painted, the entire lathe wrapped
in a water and grease-proof cover, and strongly braced and crated. In each crate is a box of "Standard Equipment."
When uncrating, first remove inside cross braces, then remove bottom outside cross braces, loosen upright boards
completely around the base, and lift the crate off the lathe. Great care should be taken in loosening crate, as a slip of the
hammer or bar can do serious damage to the lathe.
With lathe uncrated, next open your box of "Standard Equipment" and check items included against the "Standard
Equipment" listed on packing list. After all parts are accounted for, crating materials may be removed, and you are ready
to move your lathe into working position.
In selecting the proper location for your lathe, remember (1) That operation is from the apron side of lathe; allow at least
40" to 48" operator clearance in front of the lathe. (2) That the best working light should shine over the operator's
shoulders and should be ample. (3) That lathe must be on a solid (concrete if possible) foundation. If on wood floor,
flooring should be braced, if necessary to prevent sagging or settling because the lathe must be set solidly, squarely, and
rigidly, and must be level if it is to work accurately. (4) That allowance should be made back end and overhead for later
addition of taper attachments, overhead motor drive, or other accessories. End clearance of the headstock should be
provided, where possible, if bar stock is to be fed through the spindle. Where the placing of more than one lathe is
contemplated, arrangement in oblique rows will save much floor space, as long bar stock for each machine can be fed
from stock rests placed behind the adjacent lathe. (5) Bench lathes should be mounted on a heavy rigid and level bench
which should be about 28" high.
Before permanently anchoring the lathe to the floor or bench, be sure that the bed is absolutely level. Remember, no
lathe can do accurate work unless it is solidly anchored and level both along and across the bed. Shim up any low points
in floor or bench using sheet steel or other non-compressible material. After tightening anchor bolts check again for
level. Use a precision level.

BOLTING DOWN AND LEVELING YOUR LATHE
PROCEDURE FOR BOLTING DOWN LATHE
LEVELING THE LATHE
If your floor is concrete, anchor bolts are
recommended .....if on wood, lag screws. Anchor bolts
or lag screws are not supplied with the lathe.
To accurately level your lathe, a precision
machinist's level must be used. In the construction of
your lathe, the alignment tolerances were held to tenths
of thousandths of an inch. It is important that you hold
these same tolerances in leveling. A carpenter's level
or a combination square level will not give you the
accuracy required.
A precision ground bulb level
graduated in .0005" per foot is recommended.
Since the anchor bolts and lag screws must be
accurately located in the floor, pre-drilling is not
recommended.
Neither dimensional drawings nor
templates give the accurate center distances required
between bolt holes. These can only be obtained by
setting the lathe in its exact location and spotting the
center of the bolt holes in the floor.
(Mark one end of the level with a piece of chalk so
that the level always points in the same direction when
you are taking your readings.)
CONCRETE FLOORS
Back-off all of the leveling screws to be sure that
both pedestal legs are setting solidly on the floor.
Place the lathe in the location desired, selecting a
smooth surface where there are no signs of the concrete
floor sagging. Mark the holes to be drilled for the
headstock pedestal leg first. Move the lathe aside.
Since a 1/2" anchor should be used, drill the holes
approximately 7/8" x 1-1/2" deep. Drive in the anchors,
and replace the lathe. Partially screw in the hold down
bolts in order to hold the lathe in place while marking the
holes to be drilled for the tailstock pedestal.
Now place the level across both V-ways at the
headstock end of the bed. The tops of the V-ways are
precision ground to facilitate leveling, and additional
parallel blocks are not required. Adjust the two outside
leveling screws in the headstock pedestal to obtain a
"zero" reading on the level.
Move the level to the tailstock end of the bed,
adjusting the two outside leveling screws in the tailstock
pedestal to obtain the same reading as on the headstock
end.
Again, lift or move the lathe aside and drill the
tailstock holes. When these anchors are in place, the
lathe can be lifted back into position. Partially screw in
all of the hold down bolts. The lathe is now ready for
leveling.
It will be necessary to repeat this procedure several
times, making necessary minor adjustments. You will
find that adjustments at one end of the lathe will affect
the level of the other. When both ends of the lathe bed
are level, turn down the two center leveling screws until
they rest under a slight tension on the floor. This
tension should not be sufficient to change the level
reading.
WOODEN FLOORS
On wooden floors it is desirable to bolt steel plates
to the floor at the approximate location of the six hold
down and leveling screw bosses on the pedestal legs.
The steel plates should be at least 6" square and 1/4"
thick. They will provide a good firm support on which to
level the lathe and will also tend to eliminate some of
the vibration inherent in wooden floors.
Although the lathe should now be accurately
leveled, it is important to recheck the level both along
the flat way and across the bed. Very few, if any, minor
adjustments should have to be made.
Spot the hold down holes in the same way
suggested for concrete floors. Drill deep enough to
accommodate 1/2" x 6" lag screws. Spot the lathe in
place and partially tighten down on the lag screws. The
lathe is now ready for leveling.
FUTURE LEVELING
The level of your lathe should be checked at least
once a month. You will probably find it desirable to
check the lathe level as part of each new job set-up.

OUTLINE FOR REPLACEMENT OF V-BELTS
Motor drive to countershaft:
Release belt tension by rotating tension nut provided and simply slip belt off over left end of pulley.
Lower Countershaft to Upper Countershaft:
Release belt tension by raising cam lever control and rotate belt off last right step of pulley.
A - Spindle
B - Thrust Nut
C - Feed Gear
D - Spacer Collar
E - Rear Bearing Cap
F - Threaded Keeper Collar
G - Double Groove Sheave
H - Large Face Gear
I - Front Bearing Cap
J - Nose Cap
(Thread Protector)
Spindle Belts:
1. (a) Release belt tension by adjusting nuts of support located in front upper left hand corner of underneath drive
cabinet.
(b) Release set screws in countershaft collars and pulleys - slide countershaft to extreme right and remove belts.
2. Remove socket head screws from end caps and remove caps.
3. Remove set screw in thrust nut left end of spindle (taking care not to overlook the brass pad, which bears against
threaded portion of spindle.) Remove thrust nut.
4. Slide keyed gear and keyed collar off rear of spindle. IMPORTANT: REMOVE HI-PRO KEY.
5. Remove three set screws from narrow width threaded keeper collar which is located next to gear within the bowl
of headstock. (Again, do not overlook brass pad beneath set screws.) Unscrew keeper collar maximum amount
away from headstock sheave. The pulley assembly is not keyed to spindle.
6. Place two blocks of wood, one on either side of spindle between the large face gear and headstock casting.
(Wood will act as a pad to protect face gear and lockpin from damage as spindle is pressed from headstock in
the direction of the tailstock.) Replace thrust nut on spindle to protect threads - then hold a piece of tubing (with
large enough hole to clear end of spindle) against thrust nut to act as pad when driving spindle toward tailstock.
7. Drive spindle towards tailstock. (Two press fits act as resistance; one the large face gear, the other, the rear
bearing inner ring.)
8. As spindle is driven toward tailstock, unscrew keeper collar, progressively, until free from threaded portion of
spindle.
9. Lift pulley assembly out of headstock bowl, replace old "V" belts with pair of new "V" belts.

OUTLINE FOR REPLACEMENT OF V-BELTS (Cont'd)
10. Clean all assemblies.
CAUTION: Inner race of front bearing should be seated against shoulder on spindle to insure that
no dirt or grit will interfere with proper seating of bearing when headstock is reassembled.
11. Reassemble spindle assembly from front to rear.
(a) Place spindle nose cap on spindle to protect nose threads.
(b) Line up keyway of large face gear with key in spindle. By bucking up against the large face gear and
tapping against the spindle nose cap, the gear may be worked into place. The large gear will seat on the
spindle shoulder.
(c) Spindle pulley should be butted against large face gear lightly, allowing approximately .005" clearance, and
secured in place by keeper collar with set screws bearing on the small brass pads.
(d) The rear bearing may now be lightly tapped into place, or drawn into place by use of the thrust nut and
spacers.
(e) Replace HI-PRO key, collar, keyed gear, and thrust nut.
(f) Replace front and rear bearing caps. ("S" witness mark goes on bottom.)
(g) Adjust thrust nut to eliminate end play. (Secure with set screws and brass pads.)
12. Connect belts to pulley on underneath drive countershaft, tightening set screws and making sure that belt is in
alignment.
13. Adjust belt tension.
14. Lubricate spindle bearings before operating. Use S.A.E. No. 10 lubricating oil.
IMPORTANT NOTE FOR ORDERING PARTS
When ordering replacement parts, and
in all correspondence pertaining to a
lathe, reference should always be made
to the serial number, which is found on
the front flatway of the bed at the tailstock end.

It's easy to cut metric threads on your new Sheldon lathe. To set-up for metric thread cutting it is necessary to remove
some of the standard end gears and replace with special gears furnished with the metric attachment.
By using the metric threading chart above, you will be able to determine which special gear to mount on the reverse plate
stud (A), as well as determine relative position of the gear box tumbler levers (L) and (R). The metric illustration above
shows set-up for cutting 2.50 m/m pitch thread. A 40 tooth gear has been mounted on the reverse plate stud (A) in place
of the 44 tooth gear used in the English system. The left gear box tumbler lever (L) has been engaged in plunger hole
marked “B”. The right tumbler lever (R) has been engaged in plunger hole “1”. The intermediate gear (C) used on the
English system has been replaced by mounting a compound gear (127 & 110 tooth) on the intermediate gear shaft (110
tooth gear on outside.) The Knurled spacer bushing (D) on the gear box shaft has been interchanged with the 44 tooth
gear mounted on the same shaft - so that the gear is now in line with the 110 tooth gear with which it meshes.
To cut other size metric threads, refer to the metric threading chart, then install the correct gear on the reverse plate stud
as well as move the gear box tumbler levers as indicated.
When cutting metric threads, it is not possible to use the thread chasing dial in the conventional manner. Once the half
nuts are engaged, they should remain engaged until the thread being cut is completed. The tool is disengaged from the
work at the end of the cut, then the motor Is reversed, bringing the cutting tool back to the start for the next cut.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
