INTRODUCTION
About This Machine
Foreword
"The screw cutting engine lathe is the oldest and
most important of machine tools and from it all
other machine tools have been developed. It was
the lathe that made possible the building of the
steamboat, the locomotive, the electric motor, the
automobile and all kinds of machinery used in
industry. Without the lathe our great industrial
progress of the last century would have been
impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathe represented in this manual is a
modern day version of the screw cutting lathes
that trace their roots back to the 1700's, which
were themselves technological improvements of
the bow lathe that can be traced back thousands
of years to the ancient Egyptians.
Now, almost 300 years later, these modern
"screw cutting" lathes are not just a piece of
refined machinery, but a culmination of human
ingenuity and knowledge embodied into the
design and synergy of thousands of interworking
parts—some of which represent the life's work
and dreams of many inventors, mechanical
engineers, and world-class machinists—including
the likes of Leonardo da Vinci, Henry Maudsley,
and the founders of South Bend Lathe, John and
Miles O'Brien.
And now the torch is passed to you—to take
the oldest and most important type of machine
tool—and carry on the tradition. As the operator
of a South Bend Lathe, you now join the ranks
of some very famous and important customers,
such as Henry Ford, who used the machines he
purchased to help him change the world.
Capabilities
This 16-Speed Toolroom Lathe is built for daily
use in a busy industrial setting. Loaded with
many nice features and high-precision parts, this
lathe excels at making fine tools, dies, thread
gauges, jigs, and precision test gauges—however,
it is by no means delicate. Thick castings, heavy
weight, and quality construction throughout
provide the necessary brawn for demanding
production and manufacturing tasks.
South Bend Precision Toolroom Lathe
(Circa 1958)
Features
These 16-Speed Gearhead Lathes are packed
with standard features and equipment, such
as a complete coolant system, easy-to-clean
chip drawer, one-shot way lubrication system,
included steady and follow rests, chuck guard,
adjustable work lamp, foot brake, powered
cross feed, 3- and 4-jaw chucks, faceplate, and
premium Allen-Bradley contactors, thermal
relays, and fuse system.
Spindle speeds are controlled by convenient
headstock levers, which allow the operator to
quickly set the spindle speed within the available
range of 50–2570 RPM.
The beds of these lathes are constructed with
Meehanite castings that are hardened and
precision-ground in the traditional three V-way
prismatic design—long used on South Bend
Lathes for its accuracy, durability, and rigidity.
The headstocks feature quick-change gear levers
and the carriages include an adjustable clutch
that disables automatic carriage feed when it
contacts the included feed stop or in the event of
a crash.
To further ensure a high degree of accuracy,
these lathes are equipped with Japanese spindle
bearings. The spindles are D1-5 camlock with an
MT#5 taper and 1.57" bore. The tailstocks have
an MT#3 taper and 4.5" of quill travel.

Safety Foot Brake
This lathe is equipped with a foot brake (see
Figure 9) to quickly stop the spindle instead of
allowing the spindle to coast to a stop on its own.
Pushing the foot brake while the spindle is ON
cuts power to the motor and stops the spindle.
After the foot brake is used, the spindle lever
must be returned to the OFF (middle) position
to reset the spindle switches before re-starting
spindle rotation.

14" TURN-X®Toolroom Lathe SAFETY
Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are as follows:
Death or catastrophic
harm WILL occur.
Moderate injury or fire
MAY occur.
Death or catastrophic
harm COULD occur.
Machine or property
damage may occur.
Basic Machine Safety

SAFETY
Entanglement: Loose clothing, gloves, neckties,
jewelry or long hair may get caught in
moving parts, causing entanglement,
amputation, crushing, or strangulation.
Reduce this risk by removing/securing
these items so they cannot contact moving
parts.
Mental Alertness: Operating this item with
reduced mental alertness increases the
risk of accidental injury. Do not let a
temporary influence or distraction lead to a
permanent disability! Never operate when
under the influence of drugs/alcohol, when
tired, or otherwise distracted.
Safe Environment: Operating electrically
powered equipment in a wet environment
may result in electrocution; operating near
highly flammable materials may result in a
fire or explosion. Only operate this item in
a dry location that is free from flammable
materials.
Electrical Connection: With electically powered
equipment, improper connections to the
power source may result in electrocution
or fire. Always adhere to all electrical
requirements and applicable codes when
connecting to the power source. Have all
work inspected by a qualified electrician to
minimize risk.
Disconnect Power: Adjusting or servicing
electrically powered equipment while it
is connected to the power source greatly
increases the risk of injury from accidental
startup. Always disconnect power
BEFORE any service or adjustments,
including changing blades or other tooling.
Secure Workpiece/Tooling: Loose workpieces,
cutting tools, or rotating spindles can
become dangerous projectiles if not
secured or if they hit another object during
operation. Reduce the risk of this hazard
by verifying that all fastening devices are
properly secured and items attached to
spindles have enough clearance to safely
rotate.
Chuck Keys or Adjusting Tools: Tools used to
adjust spindles, chucks, or any moving/
rotating parts will become dangerous
projectiles if left in place when the machine
is started. Reduce this risk by developing
the habit of always removing these tools
immediately after using them.
Work Area: Clutter and dark shadows increase
the risks of accidental injury. Only operate
this item in a clean, non-glaring, and well-
lighted work area.
Properly Functioning Equipment: Poorly
maintained, damaged, or malfunctioning
equipment has higher risks of causing
serious personal injury compared to
those that are properly maintained.
To reduce this risk, always maintain
this item to the highest standards and
promptly repair/service a damaged or
malfunctioning component. Always follow
the maintenance instructions included in
this documentation.
Unattended Operation: Electrically powered
equipment that is left unattended while
running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.
Health Hazards: Certain cutting fluids and
lubricants, or dust/smoke created when
cutting, may contain chemicals known to
the State of California to cause cancer,
respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.
Difficult Operations: Attempting difficult
operations with which you are unfamiliar
increases the risk of injury. If you
experience difficulties performing the
intended operation, STOP! Seek an
alternative method to accomplish the
same task, ask a qualified expert how the
operation should be performed, or contact
our Technical Support for assistance.

14" TURN-X®Toolroom Lathe SAFETY
Additional Metal Lathe Safety
Clearing Chips. Metal chips can easily cut bare
skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag. Use a
brush or vacuum to clear metal chips.
Stopping Spindle by Hand. Stopping the spindle
by putting your hand on the workpiece
or chuck creates an extreme risk of
entanglement, impact, crushing, friction, or
cutting hazards. Never attempt to slow or
stop the lathe spindle with your hand. Allow
the spindle to come to a stop on its own or
use the brake.
Crashes. Aggressively driving the cutting tool
or other lathe components into the chuck
may cause an explosion of metal fragments,
which can result in severe impact injuries
and major damage to the lathe. Reduce this
risk by releasing automatic feeds after use,
not leaving lathe unattended, and checking
clearances before starting the lathe.
Make sure no part of the tool, tool holder,
compound rest, cross slide, or carriage will
contact the chuck during operation.
Coolant Safety. Coolant is a very poisonous
biohazard that can cause personal injury
from skin contact alone. Incorrectly
positioned coolant nozzles can splash on
the operator or the floor, resulting in an
exposure or slipping hazard. To decrease
your risk, change coolant regularly and
position the nozzle where it will not splash
or end up on the floor.
Tool Selection. Cutting with an incorrect or
dull tool increases the risk of accidental
injury due to the extra force required for
the operation, which increases the risk of
breaking or dislodging components that
can cause small shards of metal to become
dangerous projectiles. Always select the
right cutter for the job and make sure it is
sharp. A correct, sharp tool decreases strain
and provides a better finish.
Speed Rates. Operating the lathe at the wrong
speed can cause nearby parts to break or the
workpiece to come loose, which will result in
dangerous projectiles that could cause severe
impact injuries. Large or non-concentric
workpieces must be turned at slow speeds.
Always use the appropriate feed and speed
rates.
Chuck Key Safety. A chuck key left in the chuck
can become a deadly projectile when the
spindle is started. Always remove the chuck
key after using it. Develop a habit of not
taking your hand off of a chuck key unless it
is away from the machine.
Safe Clearances. Workpieces that crash into
other components on the lathe may throw
dangerous projectiles in all directions,
leading to impact injury and damaged
equipment. Before starting the spindle,
make sure the workpiece has adequate
clearance by hand-rotating it through its
entire range of motion. Also, check the tool
and tool post clearance, chuck clearance, and
saddle clearance.
Long Stock Safety. Long stock can whip violently
if not properly supported, causing serious
impact injury and damage to the lathe.
Reduce this risk by supporting any stock
that extends from the chuck/headstock more
than three times its own diameter. Always
turn long stock at slow speeds.
Securing Workpiece. An improperly secured
workpiece can fly off the lathe spindle with
deadly force, which can result in a severe
impact injury. Make sure the workpiece is
properly secured in the chuck or faceplate
before starting the lathe.
Chucks. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or
hands if mishandled. Get assistance when
handling chucks to reduce this risk. Protect
your hands and the precision-ground ways
by using a chuck cradle or piece of plywood
over the ways of the lathe when servicing
chucks. Use lifting devices when necessary.
