operation of the equipment, and/or a situation that may cause damage
to the machinery.

Standard Safety Instructions

SAFETY

1. Thoroughly read the Instruction Manual before operating your machine. Learn the applications,
limitations and potential hazards of this machine. Keep the manual in a safe and convenient place
for future reference.

2. Keep work area clean and well lighted. Clutter and inadequate lighting invite potential hazards.

3. Ground all tools. If a machine is equipped with a three-prong plug, it must be plugged into a

three-hole grounded electrical receptacle or grounded extension cord. If using an adapter to aid in
accommodating a two-hole receptacle, ground using a screw to a known ground.

4. Wear eye protection at all times. Use safety goggles with side shields or safety goggles that meet
the appropriate standards of the American National Standards Institute (ANSI).

5. Avoid dangerous environments. Do not operate this machine in wet or open flame environments.
Airborne dust particles could cause an explosion and severe fire hazard.

6. Ensure all guards are securely in place and in working condition.

7. Make sure switch is in the OFF position before connecting power to machine.

8. Keep work area clean, free of clutter, grease, etc.

9. Keep children and visitors away. Visitors must be kept at a safe distance while operating unit.

10. Childproof your workshop with padlocks, master switches or by removing starter keys.

11. Stop and disconnect the machine when cleaning, adjusting or servicing.

-7-

M1112 12" x 36" Gunsmithing Lathe (Mfg. Since 4/08)

12. Do not force tool. The machine will do a safer and better job at the rate for which it was
designed.

13. Use correct tool. Do not force machine or attachment to do a job for which it was not designed.

14. Wear proper apparel. Do not wear loose clothing, neck ties, gloves, jewelry, and secure long hair

away from moving parts.

15. Remove chuck keys, rags, and tools. Before turning the machine on, make it a habit to check

SAFETY

that all chuck keys and wrenches have been removed.

16. Keep proper footing and balance at all times.

17. Lock the mobile base from moving before feeding the workpiece into the machine.

18. Do not leave machine unattended. Wait until it comes to a complete stop before leaving the

area.

19. Perform machine maintenance and care. Follow lubrication and accessory attachment
instructions in the manual.

20. Keep machine away from open flame. Operating machines near pilot lights or open flames
creates a high risk if dust is dispersed in the area. Dust particles and an ignition source may cause
an explosion. Do not operate the machine in high-risk areas, including but not limited to, those
mentioned above.

21. If at any time you are experiencing difficulties performing the intended operation, stop using the
machine! Then contact our technical support or ask a qualified expert how the operation should be
performed.

22. Be aware that certain materials may cause an allergic reaction in people and animals,
especially when exposed to fine dust. Make sure you know what type of material dust you will be
exposed to and the possibility of an allergic reaction.

23. Habits—good and bad—are hard to break. Develop good habits in your shop and safety will
become second-nature to you.

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.

M1112 12" x 36" Gunsmithing Lathe (Mfg. Since 4/08)

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.

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.

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.

to concrete floors.

To connect the power cord, do these steps:

1. Make sure the power cord is NOT connected to

power.

2. Open the electrical cabinet and identify the L and
N terminals, and the grounding plate (PE) at the
bottom left of the cabinet (see Figure 13).

3. Attach insulated crimp-on wire terminals to the

wires of the power cord.

4. Securely connect the incoming ground to the PE
terminal and the two incoming hot leads to the L
and N terminals.

5. Close and secure the electrical cabinet.

Before connecting the machine to
power, always make sure the reset
button on the control panel is pushed
in to avoid unexpected start-ups.

Test Run & Break-In

The purpose of the test run and break-in is to make sure
the lathe and safety features operate correctly, and
that the lathe can enter service quickly without bearing
damage if heavy work loads are immediately anticipated.

To begin the test run & break-in procedure, do these
steps:

1. Make sure the lathe is lubricated and the headstock
oil level is full. Refer to Lubrication on Page 40.

2. Make sure the chuck is correctly secured to the
spindle. Refer to Mounting Chuck and Faceplate on
Page 22 for details.

3. Disengage the half-nut lever and the feed lever
(Figure 14).

NOTICE

NEVER shift lathe gears when lathe
is operating, and make sure both the
half-nut lever and the feed lever are
disengaged before you start the lathe!
Otherwise the lathe will feed the apron
into the chuck or tailstock causing
severe lathe damage.

— If you hear squealing or grinding noises,

turn the lathe OFF immediately and correct
any problem before further operation.

— If the problem is not readily apparent, refer

to Troubleshooting on Page 43.

9. Push the emergency stop button.

— If the lathe does not stop, turn the lathe

OFF with the spindle rotation ON/OFF
lever, and disconnect the lathe from power.
Refer to Troubleshooting on Page 43 for
correction.

10. Return the spindle rotation ON/OFF lever
to STOP, reset the emergency stop button,
restart the lathe, and let the lathe run for a
minimum of 10 minutes in both directions.

11. Turn the lathe OFF, and move the speed
levers to C and
200 RPM. Run the lathe in both directions for
10 minutes.

12. Repeat Step 9 for the remaining RPM ranges,
progressively increasing in RPM. When these
steps are complete, the lathe is broken in.

13. Drain and refill the lubricant in the
headstock with Mobil DTE Light or ISO 32 an
equivalent. Refer to Lubrication on Page 40

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).

SPINDLE SPEED

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

I (Figure 21).

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.

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.

2. Place a piece of plywood across the lathe bed, wipe

clean the spindle nose taper (Figure 25) and the
mating surface on the chuck with a rag.

3. If stamped with chuck and spindle timing marks
(Figure 26), align the marks and the camlock studs
in the back of the chuck with the holes on the
spindle face, and slide the chuck onto the spindle.

4. While supporting the weight of the chuck, turn
one cam with the chuck key until the cam line is
between the two V's on the spindle. Do not tighten
at this time.

5. Rotate the spindle and repeat Step 4 on the opposite
cam.

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.
