Additional Safety Instructions for Lathes
READ and understand this
entire instruction manual
before using this machine.
Serious personal injury
may occur if safety and
operational information is
not understood and followed. DO NOT risk your
safety by not reading!
1. AVOIDING INJURY: Read and understand this manual before operating this machine.
2. SAFE CLEANING: Do not clear chips by hand. Use a brush to avoid lacerations, and never clear
chips while the lathe is turning, or entanglement may occur.
3. USING CORRECT TOOLING: Always select the right tool bit for the job, and make sure cutting
edges are sharp. Dull or incorrect bits can break and become a projectile causing severe injury.
4. USING CHUCK KEY CORRECTLY: Never walk away from the lathe with the key in the chuck. An
accidental start can throw the chuck key with great velocity causing severe injury.
5. SECURING A WORKPIECE: Make sure workpiece is properly held in chuck before starting lathe. A
workpiece thrown from the chuck will cause severe injury.
USE this and other machinery with caution
and respect. Always consider safety first,
as it applies to your individual working
conditions. No list of safety guidelines can
be complete—every shop environment is
different. Failure to follow guidelines could
result in serious personal injury, damage
to equipment or poor work results.
SAFETY
6. CHUCK SAFETY: Get assistance when installing large chucks. Large lathe chucks are very heavy
and awkward to hold and may cause injury from dropping or lifting incorrectly, so protect your
hands and the precision ground ways. Always use a chuck cradle or piece of plywood over the bed
and ways to prevent accidental damage.
7. WORKPIECE SUPPORT: Support a long workpiece if it extends from the headstock so it will not wobble violently when the lathe is turned on. A workpiece that extends more than 2.5 times its diameter
must be supported by a center or steady rest or it may be thrown from the lathe.
8. AVOIDING STARTUP INJURIES: Make sure workpiece, cutting tool, and tool post have adequate
clearance before starting lathe. Check chuck clearance and saddle clearance before starting the
lathe. Make sure spindle RPM is set correctly for part diameter before starting the lathe. Large
parts can be ejected from the chuck if the chuck speed is set too high.
9. AVOIDING OVERLOADS: Always use the appropriate feed and speed rates. Otherwise you may
break tooling or eject a workpiece causing severe injury.
10. AVOIDING ENTANGLEMENT INJURIES: Never attempt to slow or stop the lathe chuck by hand, and
tie back long hair, ponytails, loose clothing, and sleeves so they do not dangle.
11. MAINTAINING A SAFE WORKPLACE: Never leave lathe unattended while it is running, or coworkers
or passers by may be injured severely.
12. PREVENTING LATHE CRASHES: Disengage the automatic feed levers after completing a job.

The Model M1112 weighs approximately
1400 lbs. You will need power lifting
equipment and assistance to remove
this machine from the crate and position it. Inspect all lifting equipment
and make sure that all is in perfect
working order and is rated for the load
before attempting to lift and move this
lathe. Ignoring this warning may lead to
serious personal injury or death.
7. Shim between the lathe and cabinet base as required
to make the ways level at all four corner locations as
indicated with a machinist's level.
8. Fully tighten the six hex bolts to secure the lathe to
the cabinet base.
9. For best results, recheck the ways in 24 hours to
make sure the ways are still level and have not
twisted, and re-shim as required.
10. Install the backsplash with four M6-1 x 10 Phillips
head screws and flat washers.
NOTICE
If a lathe is not level, the ways can twist out of
alignment, and cutting operations may be affected.
Make sure that your level is a high-quality machinist's
level, and that all measuring surfaces are perfectly
clean. Recheck the lathe ways in a few weeks to make
sure the floor has not settled. Re-shim as required.

Page 17
M1112 12" x 36" Gunsmithing Lathe (Mfg. Since 4/08)
Cleaning Machine
The ways and other unpainted parts of your lathe are
coated with a waxy grease that protects them from
corrosion during shipment. Clean this grease off with a
solvent cleaner or citrus-based degreaser. DO NOT use
chlorine-based solvents such as brake parts cleaner,
lacquer thinner, or acetone—if you happen to splash some
onto a painted surface, you will ruin the finish.
Machine Placement
• Floor Load: Your lathe is a heavy load distributed
in a small footprint, so you must reinforce the floor
if required. The floor MUST be level, or the lathe
frame and ways may twist and distort over time.
• Working Clearances: Consider existing and anticipated needs, service panel access, length of rods
to be loaded into the lathe, and space for auxiliary stands, work tables or other machinery when
establishing a location for your lathe (see Figure 11
for dimensions).
• Lighting: Lighting should be bright enough to eliminate shadow and prevent eye strain.
• Electrical: Outlets must be located near each
machine, so power cords are clear of high-traffic
areas.
ALWAYS work in wellventilated areas far from
possible ignition sources
when using solvents to clean
machinery. Many solvents
are toxic when inhaled or
ingested. Use care when
disposing of waste rags
and towels to be sure
they DO NOT create fire
or environmental hazards.
NEVER use gasoline or
petroleum-based solvents
to clean your lathe.
SETUP
MAKE your shop “child safe.”
Ensure that your workplace
is inaccessible to youngsters
by closing and locking all
entrances when you are
away. NEVER allow untrained
visitors in your shop when

Mounting to Shop Floor
Although not required, we recommend that you mount
your new machine to the floor. Because this is an optional
step and floor materials may vary, floor mounting
hardware is not included. Generally, you can either bolt
your machine to the floor or mount it on machine mounts.
Both options are described below. Whichever option you
choose it will be necessary to use a precision level to
level your machine.
Bolting to Concrete Floors
Anchor studs, lag screw and anchor (Figure 12) are two
popular methods for anchoring an object to a concrete
flo or. We suggest you research the many options and
methods for mounting your machine and choose the one
that best fits your specific application.
Power Connection
Before the machine can be connected to the power
SETUP
source, an electrical circuit, power cord, plug, and
receptacle must be prepared per the ELECTRICAL section
in this manual, and all previous setup instructions in the
manual must be complete to ensure that the machine has
been assembled and installed properly.
NOTICE
Anchor studs are stronger and more
permanent alternatives to lag shield
anchors; however, they will stick out of
the floor, which may cause a tripping
hazard if you decide to move your
machine at a later point.

Tailstock
The tailstock alignment was set at the factory with the
headstock. However, we recommend that you take the
time to ensure that the tailstock is aligned to your own
desired tolerances.
To align the tailstock, do these steps:
1. Center drill a 6'' long piece of bar stock on both ends. Set it aside for use in Step 4.
2. Make a dead center by turning a shoulder to make
a shank. Flip the piece over in the chuck and turn a
60° point (see Figure 16). As long as it remains in
the chuck, the point of your center will be accurate
to the spindle axis.
Note: Keep in mind that the point will have to be
refinished whenever it is removed and returned to
the chuck.
Figure 16. Finished dead center.
SETUP
3. Place the live center in your tailstock.
4. Attach a lathe dog to the bar stock from Step 1 and mount it between the centers(as shown in Figure
17).
5. Turn approximately 0.010" off the diameter.
6. Mount a dial indicator so that the plunger is on the tailstock barrel (Figure 18).
7. Measure the stock with a micrometer. If the stock is
wider at the tailstock end, the tailstock needs to be
moved toward the cutter the amount of the taper
(Figure 18).
— If the stock is thinner at the tailstock end, the
tailstock needs to be moved away from the
operator by half the amount of the taper (Figure
19).

OPERATIONS
General
NOTICE
Complete the Test Run and Break-In procedure on
Page 17 before using this lathe for any cutting or
threading operations; otherwise, gear box damage
may o cc ur.
The Model M1112 will perform many types of operations
that are beyond the scope of this manual. Many of these
operations can be dangerous or deadly if performed
incorrectly.
The instructions in this section are written with the
understanding that the operator has the necessary
knowledge and skills to operate this machine. If at any
time you are experiencing difficulties performing any
operation, stop using the machine!
If you are an inexperienced operator, we strongly
recommend that you read books, trade articles, or seek
training from an experienced lathe operator before
performing any unfamiliar operations. Above all, your
safety should come first!
Spindle Speeds
The spindle speed or RPM is controlled by the speed
control levers (Figure 21).Use the chart in Figure 22 to
find the best spindle speed required for your task.
Always wear safety goggles when operating this lathe. Failure to comply may
result in a serious eye injury resulting
in blindness.
OPERATIONS
The chart to the right shows the various combinations of
knob positions for achieving a desired speed.
Example:
To select a spindle speed of 270 RPM, move the alpha
lever until the indicator arrow points to A. Move the
numeric lever so it points to

Mounting Chuck or
Faceplate
The Model M1112 is shipped with the 3-jaw chuck
installed. This is a scroll-type chuck, meaning that all
three jaws move in unison when adjusted.
The 4-jaw chuck, on the other hand, features
independent jaws. This chuck is used for square or
unevenly-shaped stock.
If either chuck cannot hold your workpiece, the castiron faceplate has slots for T-bolts that hold standard or
custom clamping hardware. With the correct clamping
hardware, this faceplate will hold non-cylindrical parts
such as castings.
The chucks and faceplate have a D-5 Camlock mount.
Please note that there are lines stamped into the cam
and on the chuck body ( Figure 24). A chuck key is used
to turn the locking cams.
PINCH HAZARD! Protect your hands
and precision ground bedways
with plywood when removing lathe
chuck! The heavy weight of a falling chuck can cause serious injury.
To remove the existing chuck, do these steps:
1. DISCONNECT LATHE FROM POWER!
2. Place a piece of plywood across the lathe ways and
position it just under the chuck. The board should be
at least 8" wide and 10" long.
3. Turn a cam with the chuck key until the cam line
OPERATIONS
aligns with the spindle line mark shown in Figure 24.
4. Turn the other cams in the same way. Make sure to
support the chuck with one hand as you align the last
cam. The chuck may come off at this point, so be
ready to support its weight.
5. Remove the chuck key.
— If the chuck is still tight on the spindle, tap the
back of the chuck with a rubber or wood mallet
while supporting the bottom of the chuck with a
chuck cradle.
— If the chuck does not immediately come off, rotate
the spindle approximately 60˚ and tap again. Make
sure all the marks on the cams and spindle are in
proper alignment.

To load a workpiece, do these steps:
1. With the chuck key, open the jaws so the workpiece
lays flat against the chuck face and jaw step or
fits in the through hole. For jaw and work holding
options, see Figure 27.
2. Slowly turn the workpiece, and turn the chuck
wrench until the jaws make contact with the
workpiece.
3. Turn the chuck by hand to make sure you have even
contact with all three jaws and the workpiece is not
off center.
• If the workpiece is off center, loosen the jaws and
adjust the workpiece.
• If the workpiece is seated correctly, tighten the
jaws.
Securely clamp your workpiece and
remove the chuck key! Thrown objects
from a lathe can cause serious injury or
death to the operator and to bystanders
many feet away.

Swapping Jaws
The three-jaw scroll chuck has removable hardened steel
jaws (Figure 28). The outside of the jaws are used to hold
the workpiece from the outer diameter.
Numbered from 1–3, the jaws must be used in the
matching numbered jaw guides, see (Figure29).
Note: The chuck need not be removed from the spindle to
swap the jaws.
To swap a set of jaws, do these steps:
1. DISCONNECT LATHE FROM POWER!
2. Place a piece of wood over the ways to protect them
from potential damage.
3. Turn the chuck key counterclockwise and back the
jaws out.
4. Clean the jaw mating surfaces and apply a film of
white lithium grease to the mating surfaces.
5. Set the old jaws aside in a safe place free of
moisture and abrasives.
6. Rotate the chuck key clockwise until you see the tip
of the scroll-gear lead thread just begin to enter jaw
guide #1 (see Figure 30).
7. Insert jaw #1 into jaw guide #1 and hold the jaw
against the scroll gear.
8. Rotate the chuck key clockwise one turn to engage
the tip of the scroll-gear lead thread into the jaw.
Pull on the jaw now and it should be locked into the
jaw guide.

Four-Jaw Chuck
Four-jaw chucks feature hardened steel jaws that are
adjusted independently. Each jaw can be removed
from the chuck body and reversed. Independent jaw
adjustment and re versal allows for a wide range of work
holding versatility.
To install the four-jaw chuck, refer to the Mounting
Chuck or Faceplate procedures on Page 22.
To load a workpiece in the four-jaw chuck, do these
steps:
1. Using the chuck key, open each jaw so the workpiece
will lay flat against the chuck face.
2. Support the workpiece.
3. Position and lock the tailstock, then turn the
tailstock quill so the dead center makes contact or
is close to the center point of your workpiece (see
Figure 32).
4. Turn each jaw until it just makes contact with the
workpiece.
5. In an opposing pattern, tighten each jaw in small
increments. After you have adjusted the first jaw,
continue tightening the opposing jaw. Check the
dead center alignment frequently to make sure
OPERATIONS
you have not wandered off your index point due to
applying too much pressure to a single jaw.
6. After the workpiece is held in place, back the
tailstock away and rotate the chuck by hand. The
center point will move up and down when the chuck
is rotated if the workpiece is out of center.
PINCH HAZARD! Protect your hands
and precision ground bedways
with plywood when removing lathe
chuck! The heavy weight of a falling chuck can cause serious injury.
Figure 31. Simple chuck cradle made of
scrap lumber.
Securely clamp your workpiece and

7. Make fine adjustments by slightly loosening one jaw
and tightening the opposing jaw until the workpiece
is precisely aligned.
8. Use a dial indicator to fine-tune your adjustments
(see Figure 33), and use a lower RPM when
machining heavy eccentric workpieces.
PROJECTILE HAZARD! Use a lower RPM when machining
heavy eccentric workpieces. Otherwise, the workpiece
can be ejected by the chuck and cause serious injury.
Faceplate
The faceplate can be used to turn non-cylindrical parts or
for off-center turning by clamping the workpiece to the
faceplate.
Figure 33. Centering workpiece.
To install the faceplate, refer to the Mounting Chuck or
Faceplate procedures on Page 22 to mount the faceplate.
To load a workpiece, do these steps:
1. Support the workpiece on the faceplate with a
minimum of three independent clamping devices
(see Figure 34). Failure to follow this step may lead
to deadly injury to yourself or bystanders. Take into
account rotation and the cutting forces applied to
the workpiece when clamping to the faceplate. Make
sure your clamping application will not fail!
Note: Depending on the workpiece, some additional
support or counter-balance may be needed.
2. Slide the tailstock to the workpiece.
3. Lock the tailstock and then turn the tailstock quill so
the dead center makes contact with the center point
of your workpiece.
4. Lock the tailstock quill when sufficient pressure is
applied to hold the workpiece in place.
OPERATIONS
Figure 34. Faceplate with properly
clamped workpiece in four locations.
Use a minimum of three independent
clamping devices when turning eccentric
workpieces. Failure to provide adequate
clamping will cause workpiece to eject,
which may cause serious injury or death.
Note: Use a lower RPM when machining heavy
eccentric workpieces.
5. Clamp the workpiece securely and counter-balance
as needed.

Centers
A tailstock center supports stock that is too long to be
supported by the chuck alone. The tailstock barrel and
live center have an MT#3 taper. Included with this lathe
is an MT#3 to MT#5 spindle sleeve. If you need to install
a center in the spindle when using the faceplate, you can
do so by using this adapter sleeve.
Before installing any center or arbor, make sure that the
mating surfaces are perfectly clean. These parts will last
longer and remain accurate if properly maintained. If oil
is present on the mating surfaces, the tapers will not
interlock.
To install the center, insert the end of the center into
the tailstock bore until it seats. Once the workpiece is
installed, the force of a mounted workpiece will fully seat
the t ape r.
When using a live center, the tailstock barrel should
protrude about
To remove the live center, back the tailstock barrel all
the way into the tailstock casting. The live center will
pop out. Be sure to catch it when it comes out to avoid
damaging the tip.
1
⁄2" and not more than 3" (see Figure 35).
Spindle Spider
OPERATIONS
Remove the spider screws when not in use. Always
disconnect the lathe from power when installing,
removing, or adjusting the spider screws. Ignoring
this warning can lead to personal injury or machine
damage.
Figure 35. Live center installed in
tailstock.
Your lathe is equipped with a set of spindle support bolts
known as the "spider" (Figure 36). Use the spider when
a long workpiece has the potential to wobble or vibrate
when it extends through the outboard side of the lathe.
The tips of the spider screws have brass wear pads that
hold the workpiece without causing indents in the finish.
When installed, make sure to always use the jam nuts to
lock each spider screw in position. Merely tightening the
spider screws against the workpiece and leaving the jam
nuts loose is not safe. The spiders screws may loosen up
during lathe operation and crash into the lathe end cover.

Steady Rest
The steady rest supports long, small diameter stock that
otherwise could not be turned because of deflection. The
steady rest fingers are fitted with bearings that maintain
consistent non-wearing support throughout the cut. The
steady rest can also be used in place of the tailstock to
allow for cutting tool access at the end of your workpiece.
To use the steady rest, do these steps:
1. Secure the steady rest to the bedway from below
with the locking plate, then snug the mounting bolt
(Figure 37).
2. Adjust the fingers until the bearings make contact
and support the workpiece. Do not over-tighten
the fingers or they will cause deflection in the
workpiece.
Mounting Bolt
Figure 37. Steady rest in place.
3. Oil the finger bearings and the rolling surfaces while
in use to assist in friction-free support.
Follow Rest
The follow rest is normally used with small diameter
stock to prevent the workpiece from “springing” under
pressure from the turning tool. The follow rest fingers are
fitted with bearings that maintain consistent non-wearing
support throughout the cut.
To use the follow rest, do these steps:
1. Secure the follow rest to the saddle with the two cap screws (Figure 38).
2. Adjust the fingers until the bearings make contact
and support the workpiece. Do not over-tighten the
fingers as to cause deflection in the workpiece.
3. Lubricate the finger bearings and the rolling surfaces
while in use to assist in low friction support.

Feed Direction Lever
NOTICE
NEVER attempt to shift a lever while the lathe is
running! And when shifting a lever, NEVER force it. If
the lever will not engage, rotate the chuck by hand
while keeping light pressure on the lever. As the
chuck rotates it aligns the gears and the lever will
engage.
Your lathe can cut left or right while feeding or threading,
and it can cut across both ways for facing operations. This
feed direction is controlled by the feed direction lever
shown in Figure 39.
When the selection lever is positioned as depicted in
Figure 39, the carriage will move to the right along
the bed or the cross feed will travel away from the
operator. The cross feed and longitudinal feed selection is
controlled on the apron.
Figure 39. Feed direction lever.
To reverse the direction of the feeding or threading
operation, stop the lathe, move the feed direction lever
completely to the right or left.
When the lever is positioned in the middle, no gear ratio
is selected, and the gear train feeding the apron is in
neutral.
OPERATIONS
Feed Rod Lever
The feed rod can be selected by moving the lever to
the left as in Figure 40. Use this position for all feed
operations.
When the lever is positioned straight up, no drive
mechanism is selected and the gear train feeding the
apron is in neutral.
When the lever is moved to the right, no gear ratio
is selected, and the gear train feeding the apron is in
neutral.

Gearbox Levers
NOTICE
NEVER attempt to shift a lever while the lathe is
running! And when shifting a lever, NEVER force it. If
the lever will not engage, rotate the chuck by hand
while keeping light pressure on the lever. As the
chuck rotates it aligns the gears and the lever will
engage.
The two levers (Figure 41) at the bottom of the headstock
change the feed rate or the number of threads cut perinch. The left-hand lever engages in alpha positions A, B, C, D, and E; and the right-hand lever engages in numeric
positions 1, 2, 3, 4, 5, 6, 7, and 8.
Use the feed rate chart shown in Figure 42 to position
the quick change gearbox levers.
Figure 41. Quick change gearbox.
Feed Rate Chart
The far left column in the feed rate chart (Figure 42)
shows which change gears must be installed so the chart
will be applicable.
For example: Using the metric chart to make a 0.158mm
per revolution longitudinal cut, refer to the row that has
this symbol: .
Then put the left-hand lever in the C position, and the
right-hand lever in the 4 position.
To perform a facing cut, use the chart the same way
but refer to the row that has this symbol: .
Note: When either of the two selector levers are left in
the down position, the drive train is disengaged and is in
neutral.

Carriage/Cross Feed
Lever
Longitudinal and cross slide powered motions are
controlled by the carriage/cross feed lever. The lever
pivots through two stops that require moving the lever
left and right as well as up and down. Moving this lever
upward activates the automatic longitudinal feed. Moving
the lever downward activates the cross slide (Figure 43).
Half-Nut Lever and Inch
Threading
The half-nut lever clamps and releases the half-nut, which
clamps around the leadscrew (Figure 44). The lever is
only engaged while cutting threads.
Note: If the apron feed lever is engaged, the half-nut
lever is blocked from use; and if the half-nut lever is
engaged the apron lever is blocked from use. If both
levers are engaged at the same time apron damage will
o c cu r.
After the carriage has been returned, the thread dial tells
you when to re-engage the half-nut and resume threading
(Figure 44).
Figure 43. Carriage/cross feed lever in
neutral position.
Half-nut
Lever
Dial
When the cap screw is loosened, the thread dial housing
pivots so its gear can be engaged or disengaged from the
OPERATIONS
lead screw. When engaged, the dial will turn when the
lead screw and spindle are turning.
When the half-nut lever is engaged, the dial stops turning.
By carefully engaging the half-nut as the appropriate line
or number passes by the indicator mark, a thread can be
re-entered for its next pass of the cutter without wiping
out the previous cut.
The thread dial chart shown in Figure 45 indicates when
to use the thread dial if inch threads are to be cut. If an
inch thread is divisible by 8, then you don't need not use
the thread dial. If cutting metric threads, you cannot use
the thread dial.

Page 35
M1112 12" x 36" Gunsmithing Lathe (Mfg. Since 4/08)
While other thread pitches may be achieved, the Model
M1112 is designed so that gear changes are not needed for
cutting inch threads. However, you will have to move the
feed direction lever to the direction of thread you want
to cut, and then move the feed rod lever to the right. To
get the needed threads in inches, you will then use the
standard thread chart (Figure 46) to determine which
positions to move the quick change levers.
Example:
If the desired threads are 11 threads per inch (Figure 46),
move the quick change gearbox levers to positions B and
5. As the thread dial chart shows, engage the half-nut
when the thread dial reads 1 or 3 and begin your first
cut.
When the cut is complete, disengage the half-nut and
manually return the carriage to the beginning of the cut.
Watch the dial. When the 1 or the 3 on the dial comes
around to the indicator mark, engage the half-nut. Begin
your second pass. Repeat this process until the desired
depth of cut is achieved.
Change Gears & Metric
Threading
This lathe can cut 29 different metric threads, but gear
changes are required to cut all of the listed metric
threads. These gear changes take place on the left hand

9. Use a 5mm hex wrench to loosen the set screw in
the hub of gear G, and pull the gear off of the shaft.
10. Replace change gears F and G with the gears that
will produce your desired metric thread pitch and
tighten the fasteners to hold the gears on the shafts.
OPERATIONS
11. Slide the appropriate middle gear against gear G
until they mesh with (0.002" to 0.004" backlash) and
tighten the cap screw.
12. Rotate the appropriate middle gear against gear F
until they mesh with (0.002" to 0.004" backlash) and
tighten the cap screw.
Example:
If the desired metric pitch is 1.25mm, move the quick
change levers to positions 1 and C. The "Combination
of Gears" column shows that the F position change gear
needs 50 teeth and the G position change gear needs 60
teeth (Figure 49). A diagram on the left side of the chart
shows that the 50 tooth change gear meshes with the 91
tooth middle gear and the 60 tooth change gear meshes
with the 86 tooth middle gear.
Remember, you cannot use the thread dial for the metric
threads. You must keep the half-nut lever engaged
throughout the whole threading process until the threads
are complete.

Gap Piece Removal
The Model M1112 comes equipped with a gap piece
below the spindle that can be removed for turning large
diameter parts or when using a large diameter faceplate.
To remove the gap piece, do these steps:
1. DISCONNECT THE LATHE FROM POWER!
2. Using a 14mm open wrench, remove the two
index pins by turning the hex nuts (see Figure 54)
clockwise to draw the pins out of the gap piece.
3. Using an 8mm hex wrench in an alternating pattern,
remove the five cap screws (Figure 54) that hold
the gap piece in place.
4. Tap the outside of the gap piece with a dead blow
hammer or wooden mallet to loosen, and with the
help of an assistant, remove the gap piece.
To reinstall the gap piece, do these steps:
NOTICE
The gap piece is installed, then
ground at the factory for precise fit
and alignment during lathe assembly.
Factors during the remaining assembly
apply additional forces to the gap;
therefore, replacing the gap to the
original position is very difficult and
sometimes impossible.

the oil for the first time after one month of operation,
and then at six month intervals. We recommend using
Mobil Vactra 2 Oil or an ISO 68 equivalent. The apron
reservoir holds 1 pint of oil.
Figure 55. Saddle, compound, and cross-
slide lubrication.
Headstock Drain Plug
Oil Port
Cross-Slide and Compound Slide
The ball oilers on the slides (Figure 55) should be oiled
the same as the saddle.
Headstock
The oil in the headstock should be changed immediately
after break-in. Then every six months, depending
on usage. Change the headstock and apron oil more
frequently if extreme machine use is common. We
recommend using Mobil DTE Light or an ISO 32 equivalent.

Gibs
NOTICE
When adjusting gibs, keep in mind that the goal of
gib adjustment is to remove unnecessary sloppiness
from the slide movement without causing them to
bind. Loose gibs may cause poor finishes on the
workpiece. Over-tightening may cause premature
wear.
There are three areas with gib adjustments on the Model
M1112: the cross-slide gib, the compound slide gib, and the
saddle gib.
Cross Slide Gib
The gib on the cross-slide (Figure 61) is adjusted by the
two screws located at each end. To adjust, loosen the
set screw located along the edge of the cross-slide. This
set screw is provided for locking the slide for certain
operations. After making the adjustments detailed below,
tighten the set screw until it just touches the gib.
The gib is wedge shaped and by loosening the screw
closest to the operator and then tightening the opposite
screw, the slide will become looser. Conversely, loosening
the screw farthest away from the operator and tightening
the closer screw will tighten the gib. Do not over tighten.
Move the cross slide and adjust the gib until you feel a
slight drag.
Compound Gib
The compound gib (Figure 62) is adjusted by the same
method as the gibs on the cross-slide, except the screw
closest to the operator (when the compound slide is
aligned with the cross slide) must be loosened and the
screw farthest from the operator tightened to make the
gib tighter.

Saddle Gib and Saddle Lock
The saddle is supplied with a square head bolt (Figure
63) on the front right hand side of the slide. This bolt
locks the saddle in place for increased rigidity when
making face cuts. Before making adjustments to the
saddle gib, make sure that this bolt is loose by turning it
counterclockwise.
It is important that this gib stay properly adjusted. A
loose gib will cause finish problems in a workpiece. A gib
adjusted too tightly will cause premature half-nut wear.
The gib for the saddle is located on the bottom of the
back edge of the slide (Figure 63). The tension on this
gib is maintained by four set screws with jam nuts. By
loosening the jam nuts and tightening the set screws, the
gib will tighten. Loosening the set screws will loosen the
gib. The gib strip is properly adjusted when a slight drag
is felt while moving the apron. Do not over-tighten.
Saddle Lock
Bolt
Figure 63. Saddle lock bolt and saddle gib
screws.
It is important the four set screws are tightened evenly.
When tightening the jam nuts, hold the set screw in
position with a hex wrench.
Half-Nut Adjustment
If the half-nut threads do not fully mesh with the
leadscrew, the quality of the workpiece threads may
suffer. If the half-nut clamps the leadscrew too tightly,
rapid half-nut wear and a non-release or delayed half-nut
release condition could occur, which can cause chuck
and carriage crash. It is far better to have a half-nut that
clamps slightly loose rather than having it clamp too tight.
To adjust the half-nut, do these steps:
1. Engage the half-nut lever, loosen the thread dial cap screw, and rotate the dial out of the way (Figure
64).
2. Loosen the lock nuts, and while rocking the carriage
handwheel back and forth slightly, tighten the
adjustment screws until snug to seat the gibs.

Spindle Bearing Preload
This lathe is shipped from the factory with the spindle bearing preload adjusted. If the spindle ever
develops a bit of end-play and the workpiece finish suffers, you can adjust the bearing preload to
remove the end-play and improve the workpiece finish. Adjusting the bearing preload requires using a
spanner wrench or a punch and hammer. You can either purchase the spanner wrench at a tool store or
fabricate one, using the diagram shown below in Figure 66.

To adjust the preload, do these steps:
1. Run the lathe for 20 minutes on high speed to bring
the headstock to a normal temperature.
2. DISCONNECT THE LATHE FROM POWER!
3. Remove the chuck, shift the spindle to neutral, then remove the outboard spindle cover (Figure 67).
4. Place the chuck key in the cam-lock socket and keep
the spindle from rotating.
5. Using a spanner wrench or hammer-and-punch,
loosen the outer spanner lock nut (Figure 68) by
turning it counterclockwise, then remove it.
6. Loosen the inner spanner nut one turn.

M1112 12" x 36" Gunsmithing Lathe (Mfg. Since 4/08)
7. Place a wooden block over the outboard end of the
spindle, hit it soundly with a small sledge or heavy
dead blow hammer. Your goal is to slide the spindle
forward just enough to introduce spindle end-play
that you can feel by hand.
8. Place a dial indicator on the cross slide and move
the carriage toward the headstock until the contact
point of the indicator touches the spindle face
(Figure 69).
9. Move the carriage an additional 0.100
headstock.
10. Insert the chuck key into a cam socket and prevent
the spindle from turning. Tighten the inner spanner
nut until you see the motion of the needle in the
dial indicator just barely stop moving (Figure 70).
During the spanner nut tightening process, rock the
spindle back and forth slightly with the chuck key to
make sure the spindle tapered roller bearings seat
properly in the tapered bearing races.
When the dial indicator needle stops moving,
there will not be any spindle end-play nor bearing
preload. It is essential that you find this point
without tightening the spanner nut too much and
inadvertently preloading the spindle bearings.
Since it can take great effort to turn the inner
spanner nut, you may find it difficult to know if you
have gone past the zero end-play point or not. You
may find it easiest to have someone watch the dial
for you while you tighten the inner spanner nut.
If you think you may have gone past the zero endplay point, take the time to unload the bearings as
described earlier, then re-tighten the inner spanner
nut until you know you have reached the correct
setting.

Figure 69. Dial indicator set up.
Figure 70. Adjusting spindle bearings.
0.16" Travel
When you are confident that you have adjusted the
inner spanner nut until zero spindle end-play and
preload exists, you now must move the spanner
inward an additional 0.001" to set the preload.
11. To set the preload, tighten the spanner nut an
additional 0.16" along its circumference. See Figure 71 for the example of this measurement.

12. Without causing the inner spanner nut to
tighten any further, install and tighten the
outer spanner nut against the inner nut.
Do not overtighten the outer spanner nut
because additional preload can force the
bearings even tighter against the races in
the headstock and cause the headstock to
compress, crack, or cause bearing failure.
13. Position the gasket correctly, and re-install
the outboard spindle cover.
To confirm that the bearings are correctly
preloaded, do these steps:
1. Make sure all safety precautions have been
taken and set up steps are complete to make
the lathe fully operational.
2. Install the chuck and tighten the jaws.
3. Set the spindle speed to its highest setting.
4. Connect the lathe to power and turn the
lathe spindle ON.
5. Let the lathe run for 20 minutes.
6. Turn the spindle OFF, disconnect lathe
from power, and check the temperature of
the spindle.
— If the spindle nose is slightly warm to the
touch, you have correct bearing preload.
— If the spindle nose is hotter than you
can comfortably keep your hand on, the
preload is too tight and you must repeat
bearing preload adjustment procedure.

Woodstock International, Inc. will repair, replace, or arrange for a dealer refund at its expense and
at its option, the Shop Fox machine or machine part, which in proper and intended use has proven to
be defective, provided that the original owner returns the product prepaid to an authorized warranty
or repair facility as designated by our Bellingham, Washington office with proof of their purchase of
the product within two years, and provides Woodstock International, Inc. reasonable opportunity to
verify the alleged defect through inspection. If it is determined there is no defect, or that the defect
resulted from causes not within the scope of Woodstock International Inc.'s warranty, then the original
owner must bear the cost of storing and returning the product.
This is Woodstock International, Inc.’s sole written warranty and any and all warranties that may be
implied by law, including any merchantability or fitness, for any particular purpose, are hereby limited
to the duration of this written warranty. We do not warrant that Shop Fox machinery complies with
the provisions of any law, acts or electrical codes. We do not reimburse for third party repairs. In no
event shall Woodstock International, Inc.’s liability under this limited warranty exceed the purchase
price paid for the product, and any legal actions brought against Woodstock International, Inc. shall be
tried in the State of Washington, County of Whatcom. We shall in no event be liable for death, injuries
to persons or property or for incidental, contingent, special or consequential damages arising from the
use of our products.
