Faceplate: The metal disc that threads onto the

headstock spindle.

Faceplate Turning: Turning situation in which

the grain of the turning stock is at right angles
to the lathe bed axis.

Backing Block: A sacrificial piece of wood glued

to the base of the workpiece and screwed to
the faceplate. Often used to prevent mount­ing marks from appearing on the completed
workpiece.

Headstock: The cast metal box to which the

motor is attached and contains the spindle,
bearings, belts, and electrical components for
operating the lathe.

Index Head: The mechanism that allows the

headstock spindle to be locked at specific
intervals for layout or other auxiliary tasks.

Outboard Turning: Turning of workpiece with

the headstock situated at the far end of the
lathe so the work done is not over the bed of
the lathe.

Roughing Out: Taking stock from square billet to

round blank.

Spindle: This term has two meanings. First, it

refers to the threaded shaft in the headstock
to which the faceplate is attached. Second, it
refers to any work that is spindle-turned.

Spindle-Turning: Work performed where the

grain and length of the workpiece are parallel
to the axis of the bed.

Additional Safety for Wood Lathes

Serious injury or death can occur from getting entangled in, crushed between, or struck
by rotating parts on a lathe! Rotating workpieces can come loose and strike operator or
bystanders with deadly force if they are improperly secured, rotated too fast, or are not strong
enough for the rotational forces required for turning. Improper tool setup or usage can cause
tool kickback or grabbing, resulting in impact injury or entanglement. To reduce the risk of
operator (or bystander) injury or death, anyone operating this machine MUST completely heed
the hazards and warnings below.

CHECK WORKPIECE INTEGRITY. Verify each

workpiece is free of knots, splits, nails, or foreign
material to ensure it can safely rotate on spindle
without breaking apart or causing tool kickback.

PROPERLY PREPARE WORKPIECE.
Before mounting, cut off waste portions to
balance workpiece for safe rotation and remove
large edges that can catch on tooling.

SECURE LOCKS. Verify tool rest, headstock,
and tailstock are secure before turning lathe ON.

SECURE WORKPIECE. Use proven setup
techniques and always verify workpiece is
well-secured before starting lathe. Only use
high-quality fasteners with non-tapered heads for
faceplate attachment.

ADJUST TOOL SUPPORT. An improperly sup­ported tool may be grabbed or ejected. Adjust tool
rest approximately

1

⁄8" above workpiece center line to provide proper
support for turning tool. Firmly hold turning tool
with both hands against tool rest.

1

⁄4" away from workpiece and

WEAR PROPER PPE. Always wear a face shield
and safety glasses when operating lathe. Do not
wear gloves, necktie or loose clothing. Keep long
hair away from rotating spindle.

USE CORRECT SPEEDS. Select correct spindle
speed for workpiece size, type, shape, and
condition. Use low speeds when roughing or when
turning large, long, or non-concentric workpieces.
Allow spindle to reach full speed before turning.

AVOID TOOL KICKBACK. This occurs when
turning tool is grabbed or ejected from workpiece
with great force. Commonly caused by poor
workpiece selection/preparation, improper tool
usage, or improper machine setup or tool rest
adjustment.

SAFELY PERFORM ROUGHING. Use correct
tool. Take light cuts, use low speeds, and firmly
support tool with both hands.

USE SHARP TOOLS. Sharp tools cut with
less resistance than dull tools. Using dull tools
increases the risk of tool kickback or grabbing.

TEST NEW SETUPS. Test each new setup by
starting spindle rotation at lowest speed and
standing to side of lathe until workpiece reaches
full speed and you can verify safe rotation.

REMOVE ADJUSTMENT TOOLS. Remove all
chuck keys, wrenches, and adjustment tools
before turning lathe ON. These items can become
deadly projectiles when spindle is started.

CHECK CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by
hand-rotating it through its entire range of motion.

-10 -

SAFELY STOPPING ROTATION. Always allow
rotating workpiece to stop on its own. Never put
hands or another object on workpiece to stop it.

SAFELY MEASURE WORKPIECE. Only measure
workpiece after it has stopped. Trying to measure
a spinning workpiece increases entanglement
risk.

SANDING/POLISHING. To reduce entanglement
risk, remove tool rest before sanding. Never
completely wrap sandpaper around workpiece.

Model G0766 (Mfd. Since 07/15)

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: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con­sult an electrician or qualified service personnel to
ensure 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
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.

Extension cords cause voltage drop, which can
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
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

Grounding Requirements

This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.

This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

No adapter should be used with plug. If

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.

There are many ways to remove this rust preven­tative, but the following steps work well in a wide
variety of situations. Always follow the manufac­turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Site Considerations

Weight Load

Refer to the
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work­piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main­tenance and service described in this manual.

See below for required space allocation.

Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con­crete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.

Anchoring to Floor

Anchoring machinery to the floor prevents tipping
or shifting and reduces vibration that may occur
during operation, resulting in a machine that runs
slightly quieter and feels more solid.

If the machine will be installed in a commercial or
workplace setting, or if it is permanently connect­ed (hardwired) to the power supply, local codes
may require that it be anchored to the floor.

If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we rec­ommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.

Workpiece Inspection Adjusting Headstock

Some workpieces are not safe to turn or may
require modification before they are safe to turn.

Before turning, inspect all workpieces for the
following:

• Workpiece Type:
This machine is intended for turning natural

wood products. Never attempt to turn any
composite wood materials, plastics, metal,
stone, or rubber workpieces; turning these
materials can lead to machine damage or
severe injury.

• Foreign Objects:
Nails, staples, dirt, rocks and other foreign

objects are often embedded in wood. While
cutting, these objects can become dislodged
and hit the operator, cause tool grab, or break
the turning tool, which might then fly apart.
Always visually inspect your workpiece for
these items. If they can't be removed, DO
NOT turn the workpiece.

The Model G0766 headstock is equipped with a
cam-action clamping system to secure it to the
lathe bed. When the lever is tightened, a locking
plate lifts up underneath the bed and secures
the tailstock in place. The headstock can be
positioned anywhere along the lathe bed.

To position headstock along length of bed:

1. DISCONNECT MACHINE FROM POWER!

2. Loosen headstock lock lever (see Figure 16).

• Large/Loose Knots:
Loose knots can become dislodged during

the turning operation. Large knots can cause
a workpiece to completely break in half
during turning and cause machine damage
and injury. Choose workpieces that do not
have large/loose knots.

• Excessive Warping:
Workpieces with excessive bowing or twist-

ing are unstable and unbalanced. Never turn
these workpieces at high speed, or instability
will be magnified and the workpiece can be
ejected from the lathe causing injury. Only
turn concentric workpieces!

Headstock Lock

Lever

Figure 16. Headstock lock lever location.

3. Slide headstock to desired location on bed,

and use headstock lock lever to secure head­stock in position.

Note: The large clamping hex nut underneath

the headstock will require occasional adjust­ing to ensure proper clamping pressure of
the headstock to the bed. Turn this hex nut
in small increments to fine tune the clamping
pressure as needed.

Always operate lathe with headstock firmly
locked to bed. Otherwise, serious personal
injury may occur, as workpiece or faceplate
could shift during operation or be ejected
from lathe.

Model G0766 (Mfd. Since 07/15)

Tool Rest

Adjusting Tailstock

The tailstock adjusts in the same manner as the
headstock.

To position tailstock along length of bed:

1. Loosen tailstock lock lever and move tailstock

to desired position along bed, as shown in
Figure 17.

Tailstock Lock

Lever

Figure 17. Tailstock lock lever location.

2. Re-tighten tailstock lock lever to secure

tailstock to bed.

Note: The large clamping hex nut underneath

the tailstock will require occasional adjusting
to ensure proper clamping pressure of the
tailstock to the bed. Turn this hex nut in small
increments to fine tune the clamping pres­sure as needed.

Always operate lathe with tailstock firmly
locked to bed. Otherwise, serious personal
injury may occur by tailstock moving during
operation and workpiece being ejected at
high speed.

Adjusting Tool Rest

The tool rest assembly consists of two compo­nents: the tool rest base (or banjo) and the tool
rest. The tool rest base moves forward/backward
and along the length of the lathe bed. The tool
rest rotates and moves up and down in the tool
rest base. Locks for both components allow you
to secure the tool rest in position as needed after
making these adjustments.

When adjusting the tool rest, position it as close
as possible to the workpiece without actually
touching it. This maximizes support where the
cutting occurs and minimizes leverage, reducing
the risk of injury if a "catch" occurs.

Many woodturners typically set the height of the
tool rest
workpiece, depending on their height, the type of
tool they're using, and the type of operation they're
performing. As a rule of thumb: For most (spindle)
turning operations, the cutting tool should con­tact the workpiece slightly above centerline. For
most inside (bowl) turning operations, the cutting
tool should contact the workpiece slightly below
centerline.

Keeping all these factors in mind, your main goal
when adjusting the tool rest should be providing
maximum support for the type of tool being used,
in a position that is safe and comfortable for you.

Improperly supported or positioned cutting
tools can "catch" on workpiece, ejecting
tool from your hands with great force. To
reduce this risk, always ensure tool rest is
properly positioned for each type of opera­tion, cutting tool is firmly supported against
tool rest BEFORE cutting, and cutting tool
is properly positioned to cut at the correct
angle for tool and operation type.

To position tool rest forward/backward and
along the length of the bed:

2. Re-tighten tool rest base lock lever to secure

tool rest assembly in position.

1. Loosen tool rest base lock lever and move
tool rest assembly to desired position on
lathe bed, as shown in Figure 18.

Note: To maximize support, the tool rest

base should always be locked on both sides
of the bed. Never pull the tool rest so far back
that it is only secured on one side.

Always operate lathe with tool rest assem­bly firmly locked in position. Otherwise,
serious personal injury may occur by tool
being pulled from operator's hands.

To adjust angle or height of tool rest:

1. Loosen tool rest lock handle (see Figure 18).

Spindle Turning

Indexing

Indexing on a lathe is typically used for workpiece
layout and other auxiliary operations that require
equal distances around the workpiece circumfer­ence, such as clock faces or inlays.

By inserting the indexing pin into one of the four
outer indexes of the Model G0766 spindle housing
and engaging one of the 12 inner indexes in the
spindle, the workpiece can be positioned in 10°
increments, as shown in Figures 30–31.

⁄4".

Do not press the workpiece too firmly with
the tailstock or the bearings will bind and
overheat. Do not adjust the tailstock too
loosely or the workpiece will spin off the
lathe. Use good judgment and care, other­wise, serious personal injury could result
from the workpiece being ejected at high
speeds.

11. Properly adjust tool rest to workpiece (see
Adjusting Tool Rest on Page 22).

12. Before beginning lathe operation, rotate
workpiece by hand to ensure there is safe
clearance on all sides.

Keep lathe tool resting on tool rest the
ENTIRE time it is in contact with workpiece
or when preparing to make contact between
lathe tool and workpiece. Otherwise, spin­ning workpiece could force lathe tool out
of your hands or entangle your hands with
workpiece. Failure to heed this warning
could result in serious personal injury.

Spindle Turning Tips:

• When turning the lathe ON, stand away from
the path of the spinning workpiece until the
spindle reaches full speed and you can verify
that the workpiece will not come loose.

• Use the slowest speed when starting or stop­ping the lathe.

• Select the right speed for the size of workpiece
that you are turning (refer to Figure 25 on
Page 26).

• Keep the turning tool on the tool rest the
ENTIRE time that it is in contact with the
workpiece.

• Learn the correct techniques for each tool
you will use. If you are unsure about how to
use the lathe tools, read books or magazines
about lathe techniques, and seek training
from experienced and knowledgeable lathe
users.

Faceplate Turning

Faceplate Turning

Faceplate turning is when a workpiece is mounted
to the faceplate, which is then mounted to the
headstock spindle, as shown in Figure 36. This
type of turning is usually done with open-faced
workpieces like bowls or plates.

Figure 36. Typical faceplate turning operation.

Eye injuries or respiratory problems can
occur while operating this tool. Wear per­sonal protective equipment to reduce your
risk from these hazards.

Mounting Workpiece on Faceplate

1. Mark workpiece center in same manner as

described in Spindle Turning (see Page 28).

Note: Cut off corners of workpiece to make it

as close to "round" as possible, as described
in Spindle Turning, Step 5 (see Page 29).

2. Center faceplate on workpiece and attach it
(see Figure 37) with wood screws.

-30-

Figure 37. Typical attachment of faceplate to

workpiece.

Model G0766 (Mfd. Since 07/15)

NOTICE

Only use screws with non-tapered heads
(see Figure 38) to attach faceplate to the
workpiece. Screws with tapered heads can
split faceplate or snap off during operation.

Correct Incorrect

Mounting Workpiece to Backing
Block

1. Make backing block from a suitable size

piece of scrap wood.

Note: Faces of backing block must be flat

and parallel to each other, or uneven surfac­es will cause workpiece to spin eccentrically,
causing unnecessary vibration and runout. It
is best to mount backing block to faceplate
and turn other surface flat prior to mounting.

2. Locate and mark center of workpiece and
backing block.

1

3. Drill a

⁄4" hole through center of backing block.

Figure 38. Correct and incorrect screw types.

3. Thread and secure faceplate onto headstock
spindle (refer to Installing Faceplate on
Page 26).

— If wood screws cannot be placed in

workpiece, faceplate can be mounted to a
backing block attached to workpiece (see

Mounting the Workpiece to a Backing
Block).

4. Look through hole in backing block to line up

center with workpiece and glue and clamp
backing block to workpiece.

Note: Allow glue to cure according to manu-

facturer's instructions.

5. Follow Steps 1–3 under Mounting
Workpiece on Faceplate (see Page 30) to

attach backing block to faceplate.

Outboard Turning

Outboard turning is a variation of faceplate
turning and is accomplished with the headstock
positioned so the faceplate is not directly over the
bed, allowing a larger turning capacity than the
swing specification of the lathe.

The only way to rotate the headstock on this
machine is to remove it from the bed first, which
can be a heavy and cumbersome task. A much
simpler alternative to removing the headstock is
to remove the tailstock and slide the headstock
to the other end of the bed. This will position the
spindle so it is not directly over the bed whereby
outboard turning can safely be accomplished.

Model G0766 (Mfd. Since 07/15)

-31-

To outboard turn:

1. DISCONNECT MACHINE FROM POWER!

Sanding/Finishing

2. Remove tailstock and tool base from machine

by removing hex nuts and clamp washers
located underneath assemblies, then lifting
them from lathe bed.

3. Loosen headstock, then move it all the way to
tail end of lathe bed, as shown in Figure 39.

Figure 39. Example of lathe prepared for

outboard turning.

After the turning operations are complete, the
workpiece can be sanded and finished before
removing it from the lathe, as shown in Figure 40.

Figure 40. Typical sanding operation.

Note: Whenever sanding or finishing, move tool

rest holder out of the way to increase personal
safety and gain adequate working room.

4. Re-tighten headstock to bed.

When outboard turning, ALWAYS use a
floor-mounted tool rest and keep tool in
contact with rest during all turning opera­tions. Failure to do so could cause tool to be
pulled out of operator's control and ejected
at high speed.

Sandpaper

Workpiece

Wrapping sandpa­per completely around
workpiece could pull
your hands into mov­ing workpiece and may
cause serious injury.
Never wrap sandpa­per or finishing materi­als completely around
workpiece.

Model G0766 (Mfd. Since 07/15)

Selecting Turning

Tools

Lathe tools come in a variety of shapes and sizes,
and usually fall into five major categories.

• Gouges—Mainly used for rough cutting,
detail cutting, and cove profiles. The rough
gouge is a hollow, double-ground tool with
a round nose, and the detail gouge is a hol­low, double-ground tool with either a round or
pointed nose.

• Scrapers—Typically used where access for
other tools is limited, such as hollowing oper­ations. This is a flat, double-ground tool that
comes in a variety of profiles (round nose,
spear point, square nose, etc.) to match
many different contours.

Figure 43. Example of a round nose scraper.

• Parting Tools—Used for sizing and cut­ting off work. This is a flat tool with a sharp
pointed nose that may be single- or double­ground.

Figure 41. Example of a gouge.

• Skew Chisel—A very versatile tool that can
be used for planing, squaring, V-cutting,
beading, and parting off. The skew chisel is
flat, double-ground with one side higher than
the other (usually at an angle of 20°–40°).

Figure 42. Example of a skew chisel.

Figure 44. Example of a parting tool.

• Specialty Tools—These are the unique,
special function tools to aid in hollowing, bowl
making, cutting profiles, etc. The Swan Neck
Hollowing Tool shown on Page 34 is a good
example of a speciality tool.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected 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.
