About These Machines
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 lathes
are a refined culmination of human ingenuity
and knowledge embodied into the design and
synergy of many different 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 carry on
the tradition. As the operator of a South Bend
Lathe, you join the ranks of some very famous
and important customers, such as Henry Ford,
who used his South Bend lathe to help him
change the world.
Capabilities
This Heavy 10™ Gearhead Lathe is built for
daily use. 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.
Features
This Heavy 10™ Gearhead Lathe is packed with
standard features and equipment, including a
powered carriage and cross feed, 3-jaw chuck, jog
button, and spindle spider for outboard projects.
Spindle speeds are controlled by convenient
headstock levers, which allow the operator to
quickly set the spindle speed within the available
range of 55–2200 RPM.
The bed of the lathe is constructed with FC30
cast iron that is 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 gearbox features quick-change gear knobs,
and the feed rod includes a slip clutch that
disables automatic carriage feed when it contacts
the feed stop or in the event of a crash.
To further ensure a high degree of accuracy, this
lathe is equipped with German spindle bearings.
The spindle is a D1-4 camlock with an MT#5
taper and 1.358" bore. The tailstock has an MT#3
taper and 3
1⁄8" of quill travel.

Model SB1007 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
Owner’s Manual: All machinery and machining
equipment presents serious injury hazards
to untrained users. To reduce the risk of
injury, anyone who uses THIS item MUST
read and understand this entire manual
before starting.
Personal Protective Equipment: Operating or
servicing this item may expose the user
to flying debris, dust, smoke, dangerous
chemicals, or loud noises. These hazards
can result in eye injury, blindness, long-
term respiratory damage, poisoning,
cancer, reproductive harm or hearing loss.

moving parts during operation may cause
severe entanglement, impact, cutting,
or crushing injuries. Reduce this risk by
keeping any included guards/covers/doors
installed, fully functional, and positioned
for maximum protection.

South Bend Tools
For Machines Mfd. Since 12/21 Model SB1007
-11-
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.

For Machines Mfd. Since 12/21
South Bend Tools
Model SB1007 SAFETY
Additional Metal Lathe Safety
Clothing, Jewelry & Long Hair. Tie back long
hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get
caught on rotating parts and pull you into
lathe.
Rotating Parts. Always keep hands and body
at a safe distance from rotating parts—
especially those with projecting surfaces.
Never hold anything against rotating
workpiece, such as emery cloth, that can
pull you into lathe.
Guarding. Guards and covers protect against
entanglement or flying objects. Always
ensure they are properly installed while
machine is running.
Adjustment Tools. Remove all chuck keys,
wrenches, and adjustment tools before
turning lathe ON. A tool left on the lathe
can become a deadly projectile when
spindle is started.
Safe Clearances. Before starting spindle, verify
workpiece has adequate clearance by
hand-rotating it through its entire range of
motion.
New Setups. Test each new setup by starting
spindle rotation at the lowest speed and
standing to the side of the lathe until
workpiece reaches full speed and you can
verify safe rotation.
Spindle Speeds. Using spindle speeds that
are too fast for the workpiece or clamping
equipment can cause rotating parts to come
loose and strike nearby people with deadly
force. Always use slow spindle speeds with
large or non-concentric workpieces. Never
exceed rated RPM of the chuck.
Chucks. Chucks can be heavy and difficult to
hold. During installation and removal,
protect your hands and precision bed ways
by using a chuck cradle or piece of plywood
over the bed ways.
Long Stock Safety. Long stock can whip
violently if not properly supported. Always
support any stock that extends from the
chuck/headstock more than three times its
own diameter.
Clearing Chips. Metal chips can be razor sharp.
Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.
Secure Workpiece. An improperly secured
workpiece can fly off spindle with deadly
force. Make sure workpiece is properly
secured before starting the lathe.
Stopping Spindle. Always allow spindle to
completely stop on its own, or use a brake,
if provided. Never put hands or another
object on a spinning workpiece to make it
stop faster.
Crashing. A serious explosion of metal parts
can occur if cutting tool or other lathe
component hits rotating chuck or a
projecting part of workpiece. Resulting
metal fragments can strike nearby people
and lathe will be seriously damaged.
To reduce risk of crashing, ALWAYS
release automatic feeds after use, NEVER
leave lathe unattended, and CHECK all
clearances before starting lathe.
Tool Selection. Cutting with incorrect or dull
tooling increases risk of injury from broken
or dislodged components. Always use sharp
tooling that is right for the job.
Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating
parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects can also strike
nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone operating
this machine MUST completely heed the hazards and warnings below.

South Bend Tools
For Machines Mfd. Since 12/21 Model SB1007

SAFETY
Additional Chuck Safety
Entanglement. Entanglement with a rotating
chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt
to slow or stop the lathe chuck by hand,
and always roll up long sleeves, tie back
long hair, and remove any jewelry or loose
apparel BEFORE operating.
Chuck Speed Rating. Excessive spindle speeds
greatly increase the risk of the workpiece or
chuck being thrown from the machine with
deadly force. Never use spindle speeds faster
than the chuck RPM rating or the safe limits
of your workpiece.
Using Correct Equipment. Many workpieces can
only be safely turned in a lathe if additional
support equipment, such as a tailstock or
steady rest, is used. If the operation is too
hazardous to be completed with the lathe or
existing equipment, the operator must have
enough experience to know when to use a
different machine or find a safer way. If you
do not have this experience, seek additional
training (outside of this manual) from
experienced lathe operators, books, or formal
classes.
Trained Operators Only. Using a chuck
incorrectly can result in workpieces coming
loose at high speeds and striking the
operator or bystanders with deadly force.
To reduce the risk of this hazard, read
and understand this document and seek
additional training from an experienced
chuck user before using a chuck.
Chuck Capacity. Avoid exceeding the capacity
of the chuck by clamping an oversized
workpiece. If the workpiece is too large to
safely clamp with the chuck, use a faceplate
or a larger chuck if possible. Otherwise, the
workpiece could be thrown from the lathe
during operation, resulting in serious impact
injury or death.
Clamping Force. Inadequate clamping force
can lead to the workpiece being thrown
from the chuck and striking the operator
or bystanders. Maximum clamping force
is achieved when the chuck is properly
maintained and lubricated, all jaws are
fully engaged with the workpiece, and the
maximum chuck clamping diameter is not
exceeded.
Proper Maintenance. All chucks must be properly
maintained and lubricated to achieve
maximum clamping force and withstand
the rigors of centrifugal force. To reduce
the risk of a thrown workpiece, follow all
maintenance intervals and instructions in
this document.
Disconnect Power. Serious entanglement or
impact injuries could occur if the lathe is
started while you are adjusting, servicing, or
installing the chuck. Always disconnect the
lathe from power before performing these
procedures.

Power Supply
Requirements
Electrocution or fire
may occur if lathe is not
correctly grounded and
attached to the power
supply. Use a qualified
electrician to ensure a safe
power connection.
Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.
To minimize the risk of electrocution, fire,
or equipment damage, installation work and
electrical wiring must be done by a
n electrician
or qualified service personnel
in accordance with
applicable electrical codes and safety standards.
Availability
The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.
The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.
If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.
Full-Load Current Rating
Full-Load Rating at 240V.................. 6.2 Amps
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and
meets the following requirements:
For your own safety and protection of property,
consult an electrician if you are unsure about
wiring practices or applicable electrical codes.
Note: The circuit requirements in this manual
are for
a dedicated circuit—where only one
machine will be running at a time. If this
machine will be connected to a shared circuit
where multiple machines will be running at
the same time, consult a qualified electrician to
ensure the circuit is properly sized.
A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit
must be safely sized to handle the full-load
current that may be drawn from the machine for
an extended period of time. (If this machine is
connected to a circuit protected by fuses, use a
time delay fuse marked D.)
Nominal Voltage ........ 208V, 220V, 230V, 240V
Cycle .............................................................60 Hz
Phase ..............................................Single-Phase
Circuit Rating................................................ 15A
Plug/Receptacle ...............................NEMA 6-15
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power until
instructed later in this manual.

Grounding Requirements
This machine must be grounded! In the event
of
certain types of malfunctions or breakdowns,
grounding provides a path of least resistance
for electric current
in order to reduce the risk of
electric shock.
This machine is equipped with a power cord
that has
an equipment-grounding wire and a
grounding plug
(similar to the figure below).
The plug
must only be inserted into a matching
receptacle (outlet)
that is properly installed and
grounded in accordance with all local codes and
ordinances.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding wire.
If repair or replacement of the power cord or
plug is necessary, do not connect the equipment-
grounding wire to a live (current carrying)
terminal.
Check with an electrician or qualified service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the tool is properly grounded.
If you ever notice that a cord or plug is
damaged or worn, disconnect it from power, and
immediately replace it with a new one.
Extension Cords
Minimum Gauge Size............................14 AWG
Maximum Length (Shorter is Better) ....50 ft.
We do not recommend using an extension cord
with this machine. If you must use one, only
use it if absolutely necessary and only on a
temporary basis.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine
must contain a ground wire, match the required
plug and receptacle listed in the
Circuit
Requirements
for the applicable voltage, and
meet the following requirements:
Grounding Prong
Current Carrying Prongs
6-15 PLUG
GROUNDED
6-15 RECEPTACLE
FigureFigure 8. NEMA 6-15 plug and receptacle.. NEMA 6-15 plug and receptacle.
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with all
local codes and ordinances.

Model SB1007 PREPARATION
The unpainted surfaces are coated
at the factory
with a heavy-duty rust preventative that
prevents corrosion during shipment and
storage.
The benefit of this rust preventative is that it
works very well. The downside is that it
can be
time-consuming
to thoroughly remove.
Be patient and do a careful job when
cleaning
and removing the rust preventative
. The time
you spend doing this will reward you with
smooth
-sliding parts and a better appreciation
for the proper care of
the unpainted surfaces.
Although there are many ways to successfully
remove the rust preventative, the
following
process works well in most situations
.
Before cleaning, gather the following:
• Disposable
rags
• Cleaner/degreaser
(certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
• Safety
glasses&disposablegloves
Note:
Automotive degreasers, mineral spirits, or
WD•40
canbeusedtoremoverustpreventative.
Before using these products, though, test them
on an inconspicuous area of a painted surface to
make sure they will not damage it.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. Coatallsurfacesthathaverustpreventative

with a liberal amount of your cleaner or
degreaser and let them soak for a few
minutes.
3. Wipe off the surfaces. If your cleaner or
degreaser is effective, the rust preventative
will wipe off easily.
Note:
To clean off thick coats of rust preventative
on flat surfaces, such as beds or tables, use
aPLASTICpaintscrapertoscrapeoffthe
majority of the coating before wiping it off
withyourrag.(Donotuseametalscraperor

it may scratch the surface.)
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant or light oil to
prevent rust.
GAS
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used for
cleaning. Avoid using these
products to remove rust
preventative.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.
