with all of these warnings may cause serious
injury.
17. Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contain chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
3.0 Safety warnings
1. Read and understand the entire owner’s
manual before attempting assembly or
operation.
•
•
Lead from lead based paint.
Crystalline silica from bricks, cement and
other masonry products.
2. This wood lathe is designed and intended for
use by properly trained and experienced
personnel only. If you are not familiar with the
proper and safe operation of a wood lathe, do
not use it until the proper training and
knowledge have been obtained.
•
Arsenic and chromium from chemically
treated lumber.
Your risk of exposure varies, depending on
how often you do this type of work. To reduce
your exposure to these chemicals, work in a
well-ventilated area and work with approved
safety equipment, such as face or dust masks
that are specifically designed to filter out
microscopic particles.
3. Always wear approved safety glasses/face
shields while using this machine.
4. Make certain the machine is properly
grounded.
5. Before operating the machine, remove tie,
rings, watches, other jewelry, and roll sleeves
up past the elbows. Remove all loose clothing
and confine long hair. Do not wear gloves.
18. Do not operate this lathe while under the
influence of drugs, alcohol or any medication.
19. Keep tools sharp and clean for safe and best
performance. Dull tools can grab in the
workpiece and be jerked from the operator's
hands, causing serious injury.
6. Keep the floor around the machine clean and
free of scrap material, oil and grease.
7. Keep machine guards in place at all times
when the machine is in use. If removed for
maintenance purposes, use extreme caution
and replace the guards immediately.
20. Check the condition of the stock to be turned.
Make sure it is free of knots, warpage,
checked ends, improperly made or cured glue
joints and other conditions which can cause it
to be thrown out of the lathe.
8. Do not over reach. Maintain a balanced
stance at all times, so that you do not fall or
lean against rotating parts.
21. Securely fasten spur and live centers to the
material being used.
9. Make all machine adjustments or maintenance
with the machine unplugged from the power
source.
22. Check centers and tapers in the headstock
and tailstock to be sure they are free of dirt or
rust, and oil lightly before inserting centers.
10. Use the right tool. Do not force a tool or
attachment to do a job that it was not designed
to do.
23. Test each set-up by revolving the workpiece
by hand to ensure it clears the tool rest and
bed. Check the setup at the lowest speed
before increasing to operating speed.
11. Replace warning labels if they become
obscured or removed.
24. Use the correct cutting tool for the operation to
be performed and keep all tools sharp.
12. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.
25. Use low speeds for roughing and for long or
large diameter work. If vibration occurs, stop
the machine and correct the cause.
13. Give your work undivided attention. Looking
around, carrying on a conversation and "horse-
play" are careless acts that can result in
serious injury.
26. When sanding, remove the tool rest from the
machine, apply light pressure and use a slow
speed to avoid heat buildup.
14. Keep visitors a safe distance from the work
area.
27. When turning large diameter pieces, such as
bowls, always operate the lathe at low speeds.
See the speed recommendation chart in sect.
14.
15. Use recommended accessories; improper
accessories may be hazardous.
16. Read and understand warnings posted on the
machine and in this manual. Failure to comply

28. Do not attempt to engage the spindle lock pin
until the spindle has stopped. If leaving the
machine area, turn lathe off and wait until the
spindle stops before departing.
31. When stopping the lathe, never grab the part
or faceplate to slow it down. Let the work coast
to a stop.
32. Use only JET factory authorized replacement
parts and accessories; otherwise, the warranty
and guarantee are null and void.
29. Make no adjustments except speed changes
with the spindle rotating, and always
disconnect the machine from the power source
when performing maintenance to avoid
accidental starting or electrical shock.
33. Do not use this JET wood lathe for other than
its intended purpose. If used for other
purposes, JET, disclaims any real or implied
warranty and holds itself harmless from any
injury that may result from that use.
30. Provide for adequate space surrounding work
area and non-glare, overhead lighting.

7.0 Electrical connections
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating less
than 150 volts:
Electrical connections must
be made by
a
qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
8. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown
in B if a properly grounded outlet is not available.
The temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not permitted
in Canada. The green-colored rigid ear, lug, and
the like, extending from the adapter must be
connected to a permanent ground such as a
properly grounded outlet box.
The JWL-1440VS Lathe is rated at 115/230V
power, and is pre-wired for 115 volt. The lathe
comes with a plug designed for use on a circuit
with a grounded outlet that looks similar to the one
pictured in A, Figure 8.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the lathe, when operated
on 115 volt power, be connected to a dedicated
20 amp circuit with a 20 amp circuit breaker or
time-delay fuse marked “D”. When operated on
230 volt power, it is recommended that the lathe
be connected to a dedicated 15 amp circuit with a
15 amp circuit breaker or time-delay fuse marked
“D”. Local codes take precedence over
recommendations.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in D, Figure
8. The tool has a grounding plug that looks like the
plug illustrated in D. Make sure the tool is
connected to an outlet having the same
configuration as the plug. No adapter is available
or should be used with this tool. If the tool must be
reconnected for use on a different type of electric
circuit, the reconnection should be made by
qualified service personnel; and after reconnection,
the tool should comply with all local codes and
ordinances.
7.1 Grounding instructions
1. All Grounded, Cord-connected Tools:
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.

7.2 Voltage conversion
To switch the incoming power leads for 230 volt
operation:
Check with
a
qualified
1. Remove the junction box cover on the motor
and reconnect the leads according to the
diagram inside the cover. A similar diagram is
found at the back of this manual. (Note: In the
event of discrepancies, the diagram inside
junction box takes precedence.)
electrician or service personnel if the
grounding instructions are not completely
understood, or if in doubt as to whether the
tool is properly grounded. Failure to comply
may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
2. Remove the 120V plug on the end of the motor
cord and replace it with a UL/CSA listed plug
rated for 240V.

Alternatively, the lathe may be “hard-wired” to
the power source. If you are hard-wiring the
lathe to a panel, make sure a disconnect is
available for the operator. During hard-wiring
of the Lathe, make sure the fuses have been
removed or the breakers have been tripped in
the circuit to which the Lathe will be
connected. Place a warning placard on the
fuse holder or circuit breaker to prevent it
being turned on while the machine is being
wired.
4. Release knob (B) and it will seat itself with an
audible click when the headstock reaches a
positive lock position.
5. Tighten handle (A) by pulling it away from the
motor.
6. Rotate knob (B) clockwise until it engages the
threads.
Always tighten handle (A)
firmly before operating lathe.
7.3 Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary,
be sure it is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.

To remove headstock, tailstock or toolrest base
from bed, unscrew and remove either of the studs
(see N, Figure 3). After remounting these items on
the lathe, reinstall studs.
3. Pull knob outward and rotate headstock to
desired position. The headstock has seven
positive locking positions. NOTE: Be careful
not to pinch your fingers against the bed as
you rotate the headstock.
For most turning operations, except outboard
turning, the headstock is positioned at the left end
of bed, and the tailstock moved to accommodate
the workpiece.

8.4 Cam tightness
8.6 Tool rest extension
The clamping mechanisms of headstock, tailstock
and tool rest base are pre-set by the manufacturer,
and should not require adjustment.
The extension (J, Figure 13) mounts to the tool rest
base and offers greater reach for the tool rest when
turning off the bed using the headstock at an
angle, as shown.
If one of them does not tighten properly against the
bed when the locking handle is tightened, adjust it
as follows. (Figure 11 uses the tailstock as the
example.)
Make sure the clamp bushings (K, Figure 13) are
pulled apart sufficiently to accept the post of the
extension.

8.7 Locking handles
1. Remove stud from end of lathe bed, and slide
tailstock off.
Locking handles, such as H, Figure 12, are
adjustable. Simply lift out on handle, rotate it on the
pin, then release it, making sure it seats itself on
the pin.
2. Turn tailstock on its side, and tighten lock nut
(F, Figure 11) to increase cam pressure, or
loosen the nut to relieve cam pressure.
8.8 Spindle indexing
3. Mount tailstock on bed and lock it to verify
adjustment. Repeat as needed.
Indexing is used to create evenly spaced features
in a work piece, while keeping the lathe spindle
locked; for example, when cutting flutes on a
spindle blank with a hand-held router, while the
spindle blank is secured between lathe centers.
4. Reinstall stud.
8.5 Tool rest
A 12-inch tool rest is provided with your lathe. It is
designed to allow adjustment for height, position on
the bed, and angle to the work.
The JWL-1440VS lathe provides 36 indexing
positions. These are identified in the chart in
section 15.0.
Loosen locking handle on tool rest base (G, Figure
12) to slide base forward or back, and to angle it to
the bed. Tighten locking handle firmly before
operating lathe.
Loosen handle (H, Figure 12) to raise or lower tool
rest and angle it to the work. Tighten handle before
operating lathe.

from lathe.
Remove spindle index pin
before starting lathe.
5. Loosen quill lock handle (M, Figure 16).
6. Rotate the handwheel counterclockwise to
retract quill all the way, until the live center
comes out. Hold the center while doing this to
prevent it from falling.
IMPORTANT: Do not use index pin to lock spindle,
which will cause unnecessary wear to the pin. Use
spindle lock for this purpose.
8.9 Spur center: Installing/removing
The live center is installed into the headstock
spindle. The live center should first be mounted to
your workpiece, and then installed into the spindle.
See section 10.4.
1. Disconnect lathe from power source.
2. Clean the tapered end of the center, and the
inside of the headstock spindle, then push the
center into the headstock spindle.
3. To remove
a
live center, first remove
workpiece from lathe. Insert knockout rod
(Figure 15) through hole in handwheel and tap
the tapered end of the spur center.
Figure 16
8.11 Spindle lock
IMPORTANT: Hold the center by either
placing your thumb and forefinger on outside
diameter of spur center, or wrapping the center
with a rag. The center can be damaged if
allowed to fall.
Push spindle lock pin (P, Figure 17), and rotate the
spindle slightly until the pin goes entirely into the
recess. Continue to hold spindle lock pin in the
recess.

8.10 Live center: Installing/removing
The live center is installed into the tailstock quill.
1. Disconnect lathe from power source.
4. Install face plate onto threads of headstock
spindle and rotate clockwise as far as it will go.
2. Clean the tapered end of the center and the
inside of the tailstock quill, then push the
center into the quill. Test the insertion by
attempting to pull the center out of the quill by
hand. It should remain secure within the quill.
5. Face plate is now ready for turning.
6. To remove the face plate, engage spindle lock,
and turn face plate counterclockwise with face
plate wrench.
3. Always tighten the quill locking handle (M,
Figure 16), once the live center has been
properly positioned in the workpiece. Make

20) to set speed, which is displayed as RPM
(revolutions per minute) in the adjoining window
(C).
8.13 Checking center alignment
When the headstock is returned from outboard
position, the alignment between centers should be
checked.
1. Lock the headstock in normal spindle turning
position.
Do not start lathe at maximum
speed when a workpiece is mounted in the
lathe. Start at lower speed and gradually
increase to desired speed.
2. Slide the tailstock toward the headstock until
the centers almost touch (see Figure 18). Lock
the tailstock in position.
3. View the center points from top and side to
make sure they align.
4. If the centers do not align, unlock the
headstock and pivot it slightly. There should be
enough “play” in the headstock to adjust for
this alignment. Lock the headstock when
finished.
Figure 20
The JWL-1440VS contains a Reeves or “split-
pulley” system.
As speed is increased, via the speed change
handle, the spindle pulley widens and the belt
drops down to the smaller diameter between the
pulley halves. Conversely, the motor pulley, which
is spring-loaded so that it adjusts automatically to
the movement of the spindle pulley, gets narrower,
drawing the belt outward toward the larger
diameter. When the speed is decreased, the
pulleys act in opposite fashion.
Figure 18
9.0 Operating controls
Refer to Figure 19.
On/off switch (A): Pull to start lathe, push to stop.
The safety key (A1) can be removed to prevent
unauthorized use of lathe. The safety key must be
inserted to restart the lathe.
Change speed while the lathe
spindle is turning to avoid overstressing the
belt.
10.0 Operation
The information which follows is general in nature
and not intended to be a complete course in
woodturning. Nothing can replace the knowledge
gained by talking with experienced woodturners or
consulting books or trade magazines. Above all,
simple trial and error will aid in developing
proficiency in the craft.
10.1 Inspection
Figure 19
Before operating the lathe, check that everything is
in proper working order:
If a power outage should
occur during operation, the lathe will
immediately restart when power is resumed if
the start switch is still engaged. Push switch
immediately to OFF position in the event of a
power outage.
1. Level your machine; use the leveling feet to
help reduce vibration.
2. Check bearings; adjust only if endplay exists.
3. Check belt; it should be snug but not overly
tight.

4. Bed ways; keep clean, use steel wool to
remove any rust spots, and apply paste wax to
prevent buildup of rust and finishes.
5. Tool rest; use a mill file to remove nicks and
dings.
6. Spindle tapers; should be clean and free of
dust and chips for proper seating of tapers.
7. Tailstock; clean and lubricate quill and locking
device.
8. Lighting; proper lighting is essential to
eliminate shadows and reduce eye strain.
10.2 Turning Tools
If possible, select only quality, high-speed steel
turning tools. High-speed steel tools hold an edge
and last longer than ordinary carbon steel. As one
becomes proficient in turning, a variety of specialty
tools for specific applications can be acquired. The
following tools provide the basics for most
woodturning projects (see Figure 21):
Skews – 1-1/2" and 1" or 1-1/4", used to make
finishing cuts and details.
Large Roughing Gouge – 1" to 1-1/4", used to
eliminate waste wood.
Figure 21
Spindle Gouges – 1/4", 3/8", 1/2", used to turn
beads, coves and other details.
Basic Turning Tools
Deep Fluted Bowl Gouge – 1/4", 3/8" and 1/2",
used for turning bowls & plates.
Carbon steel tools can overheat easily and should
be cooled frequently. If the edge turns blue, it has
lost its temper and should be ground past the blue
area. High-speed steel tools are not as likely to
overheat, but can be damaged if allowed to get red
hot. High-speed steel tools should not be
quenched for cooling. Honing with a diamond lap
or slipstone will save trips to the grinder and keep
the edge fresh.
Square Scraper (Bedan) – 3/8” or 1/2", used to
create square shoulders.
Large Round Nose (Domed) Scraper – 1-1/2",
used to reduce ridges on interior of bowls, round
edges of bowls, etc.
Parting Tool - 1/8", used for scraping, making a
cut-off, or to set diameters for sizing.
10.3 Spindle Turning
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.
Spindle turning takes place between the centers of
the lathe. It requires a spur or drive center in the
headstock and a live or dead center in the tailstock.
A cup center rather than a cone center in the
tailstock will often reduce the risk of splitting the
stock.
For best results, use a slow speed grinder (1800
rpm) fitted with a 60-grit aluminum oxide wheel (for
shaping) and a 100-grit alum. oxide wheel (for final
sharpening and touchup). The grinder should be
located near your lathe and at a comfortable
height. A diamond dresser will keep the wheels
true and eliminate glazing.
Figure 22 shows the basic profile shapes in spindle
turning.
Never allow the tool to rest in one place on the
wheel, keep it moving and use a light touch.

10.4 Stock Selection
Never use a steel face
hammer and never drive the workpiece
onto the spur center while it is mounted in
the Lathe spindle.
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 so the
ends can be removed later. Larger stock should
have the corners removed to produce an octagon
making the piece easier to rough down to a
cylinder.
4. Make sure headstock is locked to lathe bed.
5. Clean tapered end of spur center and inside of
headstock spindle.
6. Insert tapered end of spur center (with the
attached workpiece) into headstock spindle.
1. With a combination square, or plastic center
finder for round stock, locate and mark center
on each end of the workpiece. Accuracy is not
critical on full rounds but extremely important
on stock where square sections are to remain.
Put a dimple in the stock with an awl or nail, or
use a spring-loaded automatic center punch.
7. Support the workpiece while bringing the
tailstock into position about 1-inch away from
end of workpiece. Lock tailstock to bed.
8. Advance tailstock quill with the handwheel in
order to seat the live center into the workpiece.
Use enough pressure to secure the workpiece
between the centers so that it won’t fly off, but
do not use excessive pressure.
2. Extremely hard woods may require kerfs cut
into the ends of the stock (Figure 23) using a
band saw, so the wood will accept the spur
center and the live center.
9. Tighten quill locking handle.
The tailstock quill is capable
of exerting excessive pressure against the
workpiece and the headstock. Apply only
sufficient force with tailstock to hold workpiece
securely in place. Excessive pressure can
overheat center bearings and damage both
workpiece and lathe.
10. Move tool rest into position. It should be
parallel to workpiece, just below the centerline
and approximately 1/8" to 1/4" from the
corners of the workpiece to be turned, as in
Figure 25. Tighten tool rest base to Lathe bed.
11. Rotate workpiece by hand to check for proper
clearance.
Figure 23
12. Start lathe at lowest speed and bring it up to
the appropriate RPM for the size of workpiece
used. Consult digital readout on the
headstock.
3. Drive the spur center about 1/4” into the
workpiece, using a wood mallet or dead blow
hammer as shown in Figure 24. Be careful that
you do not split the workpiece.

10.5.3 Coves
10.5 Cutting Techniques
10.5.1 Roughing Out
1. Use a spindle gouge. With the flute of the tool
at 90 degrees to the workpiece, touch the point
of the tool to the workpiece and roll in towards
the bottom of the cove. See Figure 27. Stop at
the bottom; attempting to go up the
opposite side may cause the tool to catch.
1. Begin with a large roughing gouge. Place the
tool on the tool rest with the heel of the tool on
the surface to be cut.
2. Slowly and gently raise tool handle until cutting
edge comes into contact with the workpiece.
3. Beginning about 2” from the tailstock end of
the workpiece, roll the flute (hollowed-out
portion) of the tool in the direction of the cut.
See Figure 26. Make long sweeping cuts in a
continuous motion to rough the piece down to
a cylinder.
4. Keep as much of the bevel of the tool as
possible in contact with the 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 work-piece, never start cutting at the end.
Figure 27
2. Move the tool over the desired width of the
cove.
3. With the flute facing the opposite direction,
repeat step 1 for other side of cove. Stop at
bottom of cut.
10.5.4 "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.)
Figure 26
5. Once the workpiece is roughed down to a
cylinder, smooth it with a large skew. Keep the
skew handle perpendicular to the spindle and
use only the center third of the cutting edge for
a long smoothing cut (touching one of the
points of the skew to the spinning workpiece
may cause a catch and ruin the workpiece).
2. Lightly mark the center of the "V" with the tip of
the skew.
3. Move the point of the skew to the right half of
the desired width of your cut.
4. With the bevel parallel to the right side of the
cut, raise the handle and push the tool in to the
desired depth, as shown in Figure 28.
6. Add details to the workpiece with skew, parting
tool, scraper or spindle gouge.
10.5.2 Beads
1. Make a parting cut for what is to be a bead to
the desired depth. Place the parting tool on the
tool support and move tool forward to make
the full bevel of the tool come into contact with
the workpiece. Gently raise handle to make cut
to the appropriate depth.
2. Repeat for other side of the bead.
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.
Figure 28
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.
metal screws are case hardened with deeper
and sharper threads than wood screws.)
If the mounting screws on the face plate interfere
with the workpiece, a glue or waste block can be
used:
10.5.5 Parting Off
1. Use parting tool.
2. Adjust lathe speed to lower RPM for parting
through a workpiece.
5. Make a block the same diameter as the face
plate, Figure 29. Both waste block and
workpiece should have flat surfaces for gluing.
3. Place tool on tool support and raise the handle
until it starts to cut and continue to cut toward
center of workpiece.
6. Glue the block to the workpiece. Avoid using
brown paper or newspaper between the waste
block and workpiece. It may work fine if you
are using scrapers, but a slight catch with a
bowl gouge can separate the two.
4. Loosely hold on to the piece in one hand as it
separates from the waste wood.
10.5.6 Sanding and Finishing
NOTE: When using a waste block, be careful with
the adhesive you select. Dry workpieces can be
bonded with ordinary white or yellow glue but must
be clamped to ensure a good bond. Green
workpieces require cyanoacrylate type glue.
Leaving clean cuts will reduce the amount of
sanding required. Move the tool support out of the
way, adjust the lathe to a low 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 on the
spindle. Progress through each grit without
skipping grits (for example, do not jump from 120
grit to 220 grit). 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 paper towel to
apply the finish. Remove excess finish before
restarting lathe. Allow to dry and sand again with
320 or 400 grit sandpaper. Apply second coat of
finish and buff.
10.6 Face Plate and Bowl Turning
Face plate turning is normally done on the inboard
side of the headstock over the bed. Larger
workpieces must be turned on the outboard side
(remove tailstock and tool support base, and slide
headstock to opposite end of bed).
Figure 29
10.6.2 Faceplate or Chuck?
While faceplates are the simplest, most reliable
method of holding a block of wood for turning,
chucks can also be used. As there are dozens of
chucks to choose from, the woodturner should first
consider all the different types of turning that will be
done, and read reports or discuss with other
turners who own chucks before making a decision.
10.6.1 Mounting Stock
Use of a face plate is the most common method for
holding a block of wood for turning bowls and
plates:
1. Select stock at least 1/8" to 1/4" larger than
each dimension on the finished workpiece.
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.
2. Always select the largest diameter face plate
that can be used for the workpiece to be
turned.
3. True one surface of the workpiece for
mounting against the face plate.
The most popular ones are four jaw scroll chucks
with a variety of jaws to accommodate different
size tenons. Most also come with a screw chuck as
well.
4. Using the face plate as a template, mark the
location of the mounting holes on the
workpiece, and drill pilot holes of the
appropriate size. Face plates are drilled for No.

from what appears to be the center of the top
of the workpiece.

waste wood for
a
while practicing turning
techniques. 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.
3. Slip the spur center into the headstock taper
and bring the tailstock with a live or ball
bearing center into position. Lock the tailstock
to the bed and advance the tailstock spindle in
order to seat the cup center into the
workpiece. Tighten the ram locking handle.
4. Turn workpiece by hand to ensure proper
clearance.
10.6.4 Checks and Cracks
5. Start lathe at lowest speed and bring it up to
the maximum safe speed for the size of work
to be turned. If the machine starts to vibrate,
lower the speed until vibration stops.
Green wood will check and crack. For best results,
leave logs in as long a length 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.
6. Rough out the outside of the bowl with the 1/2"
deep fluted bowl gouge, holding the handle of
the tool firmly against your hip. For best
control, use your whole body to move the
gouge through the workpiece.
As you turn bowls from green wood, make sure
7. As the bowl takes shape, work on the bottom
(tailstock end) to accommodate attaching a
face plate.
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.
8. Turn a short tenon (about 1/8" long) the size of
the hole in the faceplate. See Figure 30. This
will allow centering the workpiece when the
faceplate is attached.
10.6.5 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.
(NOTE: If you plan to use a chuck, turn a
tenon of the appropriate length and diameter
to fit your chuck.)
9. Stop the lathe, remove workpiece and attach
face plate or chuck (see section 10.6.1
"Mounting Stock").
10.6.6 Tools for Bowl Turning
The deep fluted bowl gouge is the most essential
and versatile tool for most bowl and plate turning.
The bowl gouge is heavier and easier to control
than other types of 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.
The surfaces of faceplate
and workpiece should mount flush to each
other.
10. Finish turning the outside of bowl with 1/2" or
3/8" bowl gouge. Leave additional material at
base of bowl for support while turning interior.
This will be removed later.
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.
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 occasionally left by an
inexperienced bowl gouge.

9. Begin the separation with a parting tool, but do
not cut all the way through yet.
10.7.2 To Shape Interior of Bowl
1. Stop lathe and move tailstock away. (You may
want to remove the center from the tailstock to
avoid bumping it with your elbow.)
10.7.3 Sanding and Finishing
1. Remove the tool support and adjust lathe
speed to approximately 500 RPM. Higher
speeds can build friction while sanding and
cause heat check in some woods.
2. Adjust tool support in front of the bowl just
below centerline, at a right angle to the lathe
ways.
3. Rotate workpiece by hand to check clearance.
2. Begin with fine sandpaper (120 grit) and
progress through each grit, using only light
pressure. Coarser sandpaper tends to 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.
4. Face off top of bowl by making a light shearing
cut across the top of workpiece, from rim to
center.
5. Place 1/2" bowl gouge on tool support at
center of the workpiece with the flute facing
top of bowl. The tool handle should be level
and pointed toward the four o'clock position, as
shown in Figure 31.
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.
4. Turn lathe back on and continue the
separation cut almost all the way through the
base. Stop at about 3" and use a small fine
tooth saw to separate the bowl from the waste.
5. Apply second finish coat and allow to dry
before buffing.
Figure 31
6. Use the left hand to control cutting edge of
gouge, while right hand swings tool handle
toward your body (Figure 31). 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 the tool goes
deeper into the bowl, progressively work out
toward the rim. It may be necessary to turn the
tool support into the piece as you get deeper
into the bowl.
(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 piece.
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 (Once the
piece is thin toward the bottom, you cannot
make it thinner at the rim). When the interior is
finished, move the 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

purpose grease into the zerk fitting on the motor
shaft (Figure 32) and the groove of the main
spindle (Figure 33).
11.0 Maintenance
Before doing maintenance on
the lathe, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch. Failure to comply may cause
serious injury.
11.1 General procedures
Maintenance on the lathe should be performed at
periodic intervals to ensure that the machine is in
proper working order, that all fasteners are tight,
and all necessary adjustments have been made.
Inspection and maintenance should be performed
at least twice a year, but more frequently if the
lathe receives constant use.
Figure 32
Clean and oil the lathe bed so that headstock,
tailstock and tool rest base will slide easily. Clean
any rust spots that may develop on the bed with a
commercial rust remover.
Use compressed air to blow out the interior of the
headstock, in order to keep sawdust and chips
from accumulating on belts and sheaves. Also blow
off debris that accumulates in the motor fan.
Frequently clean out the morse tapers on both
headstock and tailstock. Commercially available
taper cleaners may be acquired from tool stores.
Figure 33
Bearings are permanently lubricated and sealed,
and do not require further lubrication.
11.3 Belt and bearings replacement
Changing belt and bearings can be a difficult task,
and should be performed by a JET authorized
service center. Remove headstock and take it to a
service center for servicing.

15.0 Indexer Positions
How to use the chart
A diagram of the indexer is shown at right, as
viewed from the tailstock end of the Lathe. Points
A, B and C are the holes in the head casting. The
holes in the spindle collar may be considered as
numbered 1 through 12.
Example: You wish to rout 9 flutes on your spindle
blank. Locate the “9” in the “No. of Flutes” column;
each flute angle will be 40°. The index pin should
first be inserted into hole combination “A-1”. Make
your first flute at this position. Back off the index
pin and rotate the spindle until the index pin can be
inserted into hole combination “A-5”; this will be
followed by “A-9”. Succeeding flutes will be made
with the index pin in the B position: “B-3”, “B-7” and
so on
