Grounding Instructions
Caution: This tool must be grounded while in use to protect the operator from electric shock.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface that is green with or without yellow stripes, is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension
cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.
Repair or replace a damaged or worn cord immediately.
115 Volt Operation
As received from the factory, your lathe is ready to run at 115 volt operation. This lathe is intended for
use on a circuit that has an outlet and a plug that looks like the one illustrated in (A). A temporary
adapter, which looks like the adapter as illustrated in (B), may be used to connect this plug to a two-pole
receptacle, as shown in (B) if a properly grounded outlet is not available. The temporary adapter should
only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is
not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be
connected to a permanent ground such as a properly grounded outlet box, as shown in (B).

Speed Change
Large Domed Scraper - used to reduce ridges
on the interior of bowls, round edges of bowls,
etc, see Figure 12.
1. Disconnect the machine from the power
source!
Parting Tool - used to cut directly into the
material, or to make a cut off. Also used for
scraping and to set diameters, see Figure 12.
2. Loosen the locking handle (A, Fig. 11).
3. Lift up on the tensioning handle (B, Fig. 11)
to remove tension from the poly v-belt. You
can now position the belt in the desired
speed range. It is pictured in the low speed
pulley range. Note: The “High” speed
range (0-3200) provides maximum speed,
where as the “Low” speed range (0-1200)
will provide maximum torque.
For safety and best performance, keep tools
sharp. If a tool stops cutting, or requires
excessive pressure to make a cut, it needs to be
sharpened.
A
number of brand name
sharpening jigs and fixtures are available,
however, a woodturner should learn to sharpen
tools freehand.
4. Lower the tensioning handle so that the
weight of the motor provides the needed
tension and tighten the locking handle.
AC Inverter does not require any programming.
It is pre-programmed from the factory. The
buttons and knob on the face of inverter should

Mounting Workpiece Between Centers
Spindle turning takes place between the centers
of the lathe. It requires a spur center in the
headstock and a live center in the tailstock.
1. With a ruler locate and mark the center on
each end by going corner to corner, see
Figure 13. Accuracy is not critical on full
rounds but extremely important on stock
where square sections are to remain. Put a
dimple in each end of the stock with an awl,
or nail.
2. Extremely hard woods may require kerfs cut
into the spur drive end of stock, see Figure
13. You may need to drive the spur center
into the stock with a wood mallet. Note:
Never drive stock onto spur while it is
mounted in the lathe spindle.
3. Install workpiece by inserting the attached
spur center into the spindle taper on the
headstock.
4. Bring tailstock into position, lock it to the
bed, and advance quill with the handwheel
in order to seat the live center into the
workpiece. Lock the quill in place. Make
sure the live center point is centered on your
mark.
5. Move tool rest into position. It should be
parallel to workpiece, approximately at the
centerline, and approximately 1/8" from the
closest part of the workpiece. Lock tool rest
body and tool rest in place.
6. Rotate workpiece by hand to check for
proper clearance from tool rest. Note:
You may want to trim off the corners of a
square workpiece to make turning a little
easier, see Figure 14.
7. Start lathe at lowest speed and bring it up to
the appropriate RPM for the size of stock,
see Figure 7 page 10.
The position of the tool rest can be varied to suit
the work and operator. After you become
experienced with setting the tool rest changing
the position will become second nature for the
workpiece and comfort of the user.

Stock Selection
Stock for spindles should be straight grained
and free of checks, cracks, knots and other
defects. It should be cut 1/8" to 1/4" larger than
the finished diameter and may require additional
length to remove ends if required. Larger stock
should have the corners removed to produce an
octagon making the piece easier to rough down
to a cylinder, see Figure 14.
Roughing Out
1. Use a large roughing gouge and begin
cutting about 2” from the tailstock end of the
workpiece. Place the tool on tool rest with
heel of the tool on surface to be cut.
2. Slowly and gently raise tool handle until
cutting edge comes into contact with the
workpiece. Work to the right towards the
end of the workpiece. You never want to
start at the end of a workpiece.
3. Now continue to work the rest of the
workpiece.
Roll the flute (hollowed-out
portion) of the tool in the direction of the cut,
see Figure 15. Make long sweeping cuts in
a continuous motion to rough the piece
down to a cylinder. Keep as much of the
bevel of tool as possible in contact with
workpiece to ensure control and avoid
catches. Note: Always cut down-hill, or
from large diameter to small diameter.
Always work toward the end of a workpiece,
never start cutting at the end.
4. Once the workpiece is roughed down to a
cylinder, smooth it with a large skew. Place
the cutting point near the center of the chisel
and high on the workpiece, see Figure 16.
Touching one of the points of the skew to
the spinning workpiece may cause a catch
and ruin the workpiece.
5. Add details to the workpiece with skew,
spindle gouge, etc.
14

Coves
2. Repeat for other side of the bead.
1. Use a spindle gouge. With the flute of the
tool at 90 degrees to workpiece, touch the
center of the cutting edge to the workpiece
and roll in towards the bottom of the cove.
Stop at the bottom; attempting to go up the
opposite side may cause the tool to catch.
3. Using a small skew or spindle gouge, start in
the center between the two cuts and cut
down each side to form the bead. Roll the
tool in direction of cut.
2. Move tool over the desired width of cove.
3. With the flute facing the opposite direction,
repeat step 1 for other side of cove. Stop at
bottom of cut, see Figure 18.
“V” Cuts
1. Use the long point of the skew. Note: Do
not press the long point of the skew directly
into the workpiece to create the "V"; this will
result in a burned, or burnished "V" with
fibers being rolled up at both sides.
2. Lightly mark the center of the "V" with the tip
of the skew.
3. Move the point of skew to the right half of
the desired width of your cut, see Figure 19.
4. With the bevel parallel to the right side of the
cut, raise the handle and push the tool in to
the desired depth.
5. Repeat from the left side. The two cuts
should meet at the bottom and leave a clean
"V" cut.
6. Additional cuts may be taken to add to either
the depth or width of the cut.
Parting
1. Place parting tool on tool rest and raise the
handle until it starts to cut and continue to
cut to the desired depth.
2. If the cut is deep a clearance cut should be
made along side the first cut to prevent the
tool tip from burning.
Beads
1. Place parting tool on tool rest and move tool
forward to make the full bevel of tool come
in contact with workpiece. Gently raise
handle to make cut to appropriate depth.

Sanding & Finishing
Leaving clean cuts will reduce the amount of
sanding required. Adjust lathe to a finishing
speed, and begin with fine sandpaper (120 grit
or finer). Coarser sandpaper will leave deep
scratches that are difficult to remove, and dull
crisp details. Fold the sandpaper into a pad; do
not wrap sandpaper around your fingers or the
workpiece.
To apply a finish, the workpiece can be left
on the lathe. Turn off lathe and use a brush, or
cloth to apply the finish. Remove excess finish
before restarting lathe. Allow to dry and sand
again with 320, or 400 grit sandpaper. Apply
additional coats of finish and buff.
Face Plate & Bowl Turning
Face plate turning is normally done on the
inboard side of the headstock over the bed, see
Figure 20. You must move headstock to the
end of the lathe bed for larger workpieces.
Mounting Stock
Use of a face plate is the most common method
for holding a block of wood for turning bowls,
and plates, see Figure 21.
1. Select stock at least 1/8" to 1/4" larger than
the dimension on the desired finished
workpiece.
2. True one surface of workpiece for mounting
against the face plate. It is best to leave
extra stock against the face plate that can
be cut off when the workpiece is finished.
3. Using the face plate as a template, mark the
location of the mounting holes, and drill pilot
holes of the appropriate size.
If the
mounting screws on the face plate interfere
with the workpiece, a waste block can be
mounted to the face plate and then the
waste block mounted to the workpiece by
gluing or screwing, see Figure 21.
4. Both waste block and workpiece should
have good flat surfaces.
5. Push in the spindle lock and thread face
plate and workpiece onto spindle. Tighten
set screws in face plate when secure.

gouges. It also allows removal of wood much
faster and with less vibration than other gouges.
Most average sized bowl work can be
accomplished with a 3/8" or 1/2" bowl gouge. A
1/4" bowl gouge is best suited for smaller bowls
and light finishing cuts. Larger 3/4" and 1" bowl
gouges are only used for extremely large pieces.
Face Plate or Chuck
While faceplates are the simplest, most reliable
method of holding a block of wood for turning,
chucks can also be used. A chuck is not a
requirement but is handy when working on more
than one piece at a time. Rather than removing
screws, you simply open the chuck and change
workpieces. The most popular ones are four
jaw scroll chucks with a variety of jaws to
accomodate different size tenons. Most also
come with a screw chuck as well.
Large domed scrapers can also be used to help
clean up the interior surfaces of bowls. A light
touch with the scraper slightly tilted will eliminate
some of the ridges left by a bowl gouge.
Wood Selection
Firewood is the cheapest, most widely available
stock to use while learning to turn bowls.
Develop skill with each tool before attempting to
make a finished piece. It is best to start with
dry wood, without worrying about drying or
distortion. Once turning becomes comfortable,
try green wood which cuts very easily. As the
turner gains experience, he or she will find
extraordinary grain and figure in the form of
burls, crotches and bark inclusions.
Checks & Cracks
Green wood will check and crack. For best
results, leave logs in as long lengths as you can
handle. As the material starts to dry, surface
cracks will develop on the ends of the log. Cut
off two to three inches and you should find good,
sound wood. Also cut the log in half along the
pith to avoid having it in the finished piece.
Most checks radiate from the pith. As you turn
bowls from green wood, make sure you maintain
a consistent wall thickness throughout the piece.
Leaving a piece thick in some areas and thin in
others will cause the wood to dry unevenly and
promote checks and cracks.
Distortion
Distortion is a problem associated with turning
green wood. It will vary from one type of wood
to the next. Typically, fruitwoods tend to distort
more than others. It also varies with the time of
year the tree was cut and how the logs are
stored.
Tools for Bowl Turning
The deep fluted bowl gouge is the most
essential and versatile tool for most bowl and
faceplate style turning. The bowl gouge is
heavier and easier to control than other types of

material at base of bowl for support while
turning interior. This will be removed later.
2. Drive spur center into the top of workpiece
with a wood mallet.
3. Slip spur center into headstock taper and
bring the tailstock, with a live center into
position. Lock tailstock to bed and advance
spindle in order to seat the cup center into
workpiece, see Figure 22. Tighten quill
lock.
4. Position tool support just below the
centerline and about 1/4" from the
workpiece.
Note: For larger outboard
turning, an optional outboard turning stand is
used to place the tool support, see your JET
distributor.
5. Turn workpiece by hand to ensure proper
clearance.
6. Start lathe at lowest speed and bring it up to
the maximum safe speed for the size of
work to be turned, see Figure 7 on page 10.
If the machine starts to vibrate, lower the
speed until vibration stops.
7. Rough out the outside of the bowl with the
1/2" deep fluted bowl gouge, holding the tool
firmly against your hip. For best control,
use your whole body to move the gouge
through the workpiece.
8. As the bowl takes shape, work on the
bottom (tailstock end) to accomodate
attaching a face plate, see Figure 22.
9. Turn a short tenon (about 1/8" long) the size
of the hole in the faceplate, see Figure 22.
This will allow centering the workpiece when
the faceplate is attached. Note: If you
plan to use a chuck, turn a tenon of
appropriate length and diameter to fit your
chuck.
10. Stop the lathe, remove workpiece and attach
face plate, or chuck.

To Shape Interior of Bowl
speed can build friction while sanding and
cause heat check in some woods.
1. Stop lathe and move tailstock away.
Remove center from tailstock to prevent
bumping it with elbow.
2. Begin with fine sandpaper 120 grit and
progress through each grit, using only light
pressure.

leave deep scratches that are hard to
eliminate. Use power-sanding techniques
to avoid concentric sanding marks around
your finished piece. Avoid rounding over the
rim and foot with sandpaper. Try to keep
details crisp. Finish sanding with 220 grit.
3. Rotate workpiece by hand to check
clearance.
4. Face off top of bowl by making a light
shearing cut across the workpiece, from rim
to center.
3. Remove sanding dust with tack rags, or
compressed air and, with lathe turned off,
apply first coat of finish. Let stand for
several minutes, wipe off excess. Allow to
dry before sanding again with 320 or 400 grit
sandpaper.
5. Place 1/2" bowl gouge on tool rest at center
of the workpiece with the flute facing top of
bowl. The tool handle should be level and
pointed toward four o'clock, see Figure 23.
4. Turn lathe back on and make a separation
cut through the base. Stop at about 3" and
use a small fine tooth saw to separate the
bowl from the waste.
6. Use left hand to control cutting edge of
gouge, while right hand swings tool handle
around toward your body, see Figure 23.
The flute should start out facing top of
workpiece, and rotate upward as it moves
deeper into the bowl to maintain a clean
even curve. As tool goes deeper into bowl,
progressively work out toward rim. It may be
necessary to turn the tool rest into the work
piece as you get deeper into the bowl.
5. Apply additional finish coats and allow to dry
before buffing.
Note:
Try to make one, very light
continuous movement from the rim to the
bottom of the bowl to ensure a clean,
sweeping curve through the workpiece.
Should there be a few small ridges left, a
light cut with a large domed scraper can
even out the surface.
7. Develop wall thickness at the rim and
maintain it as you work deeper into the bowl.
When the interior is finished, move tool
support to exterior to re-define bottom of
bowl. General rule of thumb: the base
should be approximately 1/3 the overall
diameter of the bowl.
8. Work the tight area around faceplate or
chuck with 1/4" bowl gouge.

Adjusting Clamping Mechanism
The clamps are pre-set at the factory and should
not need any adjustment.
However, if
adjustment is needed remove the stud (A, Fig.
24). Loosen the locking handle and slide the
headstock, tailstock or tool rest to the edge of
the bed and slightly turn the hex nut (B, Fig. 24).
Slide back into position and test the handle to
make sure it securely locks.
Changing the Belt and Bearings
Changing belt and bearings can be a difficult
task, and should be performed by a JET
authorized repair station. Remove headstock
and take into a repair station for servicing.
1. Disconnect the machine from the power
source!
2. Loosen the locking handle (C, Fig. 25), and
lift up on the tensioning handle (D, Fig. 25)
to remove tension from the poly v-belt.
3. Open door (E, Fig. 25), and remove the belt
(F, Fig. 25) from the lower pulley.
4. Loosen two set screws in the handwheel (G,
Fig. 25) and remove.
5. Loosen socket head cap screw enough to
unthread the clamping nut (H, Fig. 25).
6. Loosen two set screws in the right hand
pulley (I, Fig. 25).
7. Loosen set screw in the collar (J, Fig. 26)
8. Use a wood dowel, or aluminum stock to
knock spindle towards the tailstock. Use a
material that is softer than the spindle so
you do not mushroom end of spindle. Go
only far enough to remove belt from spindle,
see Figure 26.
9. Now you can replace the belt or bearings.
There are two bearings #5, and 10 that can
be seen in “Headstock Assembly,” page 24.
10. To reassemble reverse the procedure.
Note:
When reinstalling clamping nut
thread it on to the spindle until its snug.
Then back off slightly and tighten the socket
head cap screw.
