Machine Description
A lathe removes material from a rotating workpiece
secured to the spindle with a chuck or faceplate. A
cutting tool is mounted in the tool post or tailstock
and moved against the spinning workpiece to
perform the cut.
This micro lathe is great for jewelers, model makers, or hobbyists who want to turn small parts,
but don't have the need (or space) for a full-sized
lathe. It features a 4" swing, 6" distance between
centers, variable-speed spindle, and a 3-jaw
chuck.

Additional Safety for Metal Lathes
Serious injury or death can occur from getting entangled in, crushed between, or struck by
rotating parts on a lathe! Unsecured tools or workpieces attached to 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.
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 PAR T S. 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
injuries from entanglement or flying objects. Always
ensure they are properly installed and positioned
before startup.
ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A chuck key or other 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 handrotating it through its entire range of motion.
NEW SETUPS. Test each new setup by standing
to the side of the lathe and starting spindle rotation
at the lowest speed 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 rate RPM of the chuck.
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. 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, NEVER leave lathe unattended, and CHECK all clearances before starting
lathe.
SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating
workpiece. Instead, use emery cloth with the aid
of a tool or backing board.
MEASURING WORKPIECE. To reduce risk of
entanglement, never measure a spinning workpiece.

SECTION 2: POWER SUPPLY
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 an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
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 specified circuit requirements.
For your own safety and protection of
Note: The circuit requirements listed in this man-
ual apply to 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 that the
circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current 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.)
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:

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 a qualified electrician or 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.
We do not recommend using an extension cord

To complete a typical operation, the operator
does the following:
1. Puts on safety glasses and a face shield, ties
back long hair, rolls up long sleeves, removes
loose clothing, jewelry, or gloves that could
get entangled in moving parts.
2. Examines the workpiece to make sure it is
suitable for turning, then securely mounts the
workpiece in a chuck, faceplate, or between
centers.
3. Mounts the tooling, aligns it with the workpiece,
then backs it away to establish a safe startup
clearance.
4. Clears all setup tools from the lathe.
5. Checks for safe clearances by rotating the
workpiece by hand at least one full revolution.
6. Starts spindle rotation.
7. Sets the correct spindle speed for the opera-
tion.

Chuck & Faceplate
Installation &
Mounting
This lathe is equipped with an M14-1.0 threaded
spindle nose. With this type of spindle, the chuck
or faceplate (not included) screws directly onto the
spindle nose.
Never use spindle speeds faster than the
chuck RPM rating or the safe limits of
your workpiece. Excessive spindle speeds
greatly increase the risk of the workpiece or
chuck being thrown from the machine with
deadly force!
Loose hair, clothing, or
jewelry could get caught
in machinery and cause
serious personal injury.
Keep these items away
from moving parts at all
times to reduce this risk.
Removal Device
Because a chuck may become damaged or damage the bedways if dropped, always use a support
or protective device during installation or removal.
Refer to the following figure for an example.
Plywood Protection
Plate for Chucks
Installed by Hand
Figure 15. Example of common device used
during chuck installation and removal.
This lathe ships with the 3-jaw chuck installed.
This is a scroll-type chuck where all three jaws
move in unison when the chuck key is used.
If the chuck cannot hold your workpiece, use a
faceplate (not included) with slots for T-bolts that
hold standard or custom clamping hardware. With
the correct clamping hardware, a faceplate offers
a wide range of uses, including machining nonconcentric workpieces, straight turning between
centers, and boring.

Model G0745 (Mfg. Since 11/13)
Chuck Installation &
Removal
To ensure accurate work, it is extremely important
that the spindle nose and chuck mating surfaces
remain clean during installation. Even a small
amount of dirt or debris can affect accuracy.
The chuck is properly installed when it threads
all the way onto the spindle nose (see Figure 16)
and evenly seated against the spindle shoulder.
6. Insert the spindle key and chuck key, as
shown in Figure 17, and tighten the chuck
snug against the spindle shoulder.
2. Use an appropriate device to protect the ways (refer to Installation & Removal Device on
Page 20).
3. Remove the cap screw that secures the end
cover, then open the end cover.
4. Use the spindle key and chuck key, as shown
in Figure 17, to loosen and remove the
chuck.
2. Use an appropriate device to protect the
ways during the installation process (refer
to Installation & Removal Device on Page
20).
3. Thoroughly clean, inspect, deburr, and lightly
oil all threads and mating surfaces.
4. Thread the chuck onto the spindle nose and
hand-tighten it.
5. Remove the cap screw that secures the end
cover, then open the end cover.

Reversing Jaws
The included 3-jaw scroll chuck features reversible hardened steel jaws (see Figure 18) that
move in unison to converge evenly against concentric workpieces.
Using the stamped numbers, the jaws are installed
in numerical order in the jaw guides (see Figure
20), so they will converge.

Figure 18. Chuck with reversible jaws.
When installing the jaws, it is important to make
sure they are installed correctly. Incorrect installation will result in jaws that do not converge evenly
and are unable to securely clamp a workpiece.
All of the tall ends of the jaws—or all of the low
ends—should face each other when installed (see
Figure 18). The jaws should be oriented so they
correctly hold the workpiece (refer to Figure 22
on Page 23).
Each end of a jaw is stamped with a number (1, 2,
or 3), as shown in Figure 19.

Scroll Chuck
Clamping
This 3-jaw scroll-type chuck has an internal scrollgear that moves all jaws in unison when adjusted
with the chuck key. This chuck holds cylindrical
parts on-center with the axis of spindle rotation
and can be rotated at high speeds if the workpiece
is properly clamped and balanced.
Never mix jaw types or positions to
accommodate an odd-shaped workpiece. The
chuck will spin out of balance and may throw the
workpiece! Instead, use an independent jaw chuck
or a faceplate (not included).
6. Insert jaw #1 into the same jaw guide.
7. Rotate outer ring so tip of scroll-gear lead
thread engages jaw. Pull the jaw; it should be
locked into the jaw guide.
8. Install remaining jaws in numerical order in
the same manner, starting to the right of the
jaw you just installed. The jaws should converge evenly at the center of the chuck when
properly installed.
Tip:To ensure smooth installation, make
sure the jaws are straight up and down and
do not bind in the scroll gear.
— If the jaws do not converge evenly, remove
them. Re-install the jaws sequentially 1–3,
and make sure each one engages with the
scroll-gear lead thread during its first rotation.

Tailstock
The tailstock is typically used to support long
workpieces at the opposite end of the spindle,
using a center. It can hold a drill chuck (not included) with a regular drill bit for boring holes. Unlike
boring done with a drill press where the workpiece
is fixed and the drill bit rotates, the drill bit in a
tailstock remains stationary while the workpiece
is rotated by the spindle.
The entire tailstock can be repositioned and
locked in place along the length of the bed with
the tailstock lock screw.
The tailstock quill features a handwheel that
moves it toward or away from the spindle in a precise manner; it is locked with the quill lock screw.

Carriage & Slide
Locks
The carriage and cross slide have screws that can
be tightened to provide additional rigidity during
operation, especially during heavy cuts.
See Figure 27 to identify the locations of the
locks for each device.
Tool Post
The tool post is mounted on top of the cross slide
and allows one tool to be loaded at a time.
1. Adjust the tool post screws so the cutting tool can fit underneath them (see Figure 28).
Cutting
Tool
Figure 28. Example of tool mounted in tool post.
Over-extending a cutting tool from the
tool post will increase the risk of tool
chatter, breakage, or tool loosening during
operation, which could cause metal pieces
to be thrown at the operator or bystanders
with great force. DO NOT extend a cutting
tool more than 2.5 times the width of its
cross-section (e.g., 2.5 x 0.5" = 1.25").

Spindle Speed
Using the correct spindle speed is important for
getting safe and satisfactory results, as well as
maximizing tool life.
The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect cutting
speed and they are a good educational resource.
To set the spindle speed for your operation, you
will need to: 1) Determine the best spindle speed
for the cutting task, and 2) configure the lathe
controls to produce the required spindle speed.
Determining Spindle Speed
Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed for
the workpiece material and the diameter of the
workpiece, as noted in the formula shown below.
*Recommended
Cutting Speed (FPM) x 12
Dia. of Cut (in inches) x 3.14
Spindle
Speed
=
(RPM)
*Double if using carbide cutting tool
Figure 32. Spindle speed formula for lathes.
Cutting speed, typically defined in feet per minute
(FPM), is the speed at which the edge of a tool
moves across the material surface.
Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take into
account the applicable variables in order to determine the best spindle speed for the operation.
Selecting Spindle Speed
Twist the emergency stop button clockwise to
reset it, then rotate the spindle speed dial (Figure
33) until the desired spindle speed is achieved.
Spindle Speed
Dial

A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.

The carriage handwheel backlash is adjusted with
the leadscrew supports (see Figure 39).
Cap Screws
Supports
Figure 39. Carriage adjustment screws and
leadscrew supports.
The cross slide backlash is adjusted by loosening
Phillips head screw (see Figure 38). When the
screw is tightened, the leadscrew nut draws the
leadscrew up, removing free-play.

screw.
To adjust the backlash, move the tool post out
of the way, or remove it. Then, rock the cross
slide handwheel back and forth, and tighten the
screw slowly until the backlash is approximately
0.002"–0.003" as indicated on the graduated dial.
To access the leadscrew supports, remove the
leadscrew cover. Loosen the four cap screws,
push the leadscrew supports towards the center
of the lathe, then tighten the cap screws. Turn the
handwheel—backlash should be approximately
0.002"–0.003" as indicated on the graduated
dial. If the adjustment is too tight, loosen the
cap screws, and re-adjust the supports until the
handwheel turns freely. Re-install the leadscrew
cover when finished.
If you end up adjusting the nut too tight, loosen
the screw, turn the handwheel back and forth until
it turns freely—then try again.

Gib Adjustment
The goal of adjusting the cross slide gib is to
remove sloppiness or free-play from the ways
without making the cross slide overly stiff and difficult to move.
In general, loose gibs cause poor finishes and
tool chatter. Over-tightened gibs cause premature
wear and make the handwheel difficult to turn.
V-Belt Tension &
Replacement
The V-belt stretches and wears with use. An
improperly tensioned V-belt will slip or poorly
transmit power from the motor. Check the tension
on a monthly basis to ensure optimal power transmission. Replace the V-belt if it becomes cracked,
frayed, or glazed.

Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is connected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual when connecting your machine to a power
source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
