7.0 Electrical connections
The JWL-1221SP JET lathe is rated for 115 volt
operation. It is supplied with a plug designed for
use on a circuit with a grounded outlet that looks
like the one pictured in A, Figure 7-1.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the lathe be connected to a
dedicated 10 amp circuit with a circuit breaker or
time-delay fuse. Local codes take precedence
over recommendations.
7.1 GROUNDING INSTRUCTIONS
1. All Grounded, Cord-connected Tools:
This tool must be grounded. 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
10
replacement of the electric cord or plug is
necessary, do not connect the equipmentgrounding 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. 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.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating less
than 150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
7-1. 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.

8.0 Adjustments
Make sure all levers and
locking handles are tightened be fore operating
the lathe.
8.1 Tool rest
Refer to Figure 8-1:
The tool rest assembly is designed to allow
adjustment for height, position on the bed, and
angle to the work.
Loosen locking handle (A) on tool rest base to slide
base forward or back, and to angle it to the bed.
Tighten locking handle firmly before operating
lathe.
Loosen small handle (B) to raise or lower tool rest
and angle it to the work. Tighten handle before
operating lathe.
Figure 7-1
7.2 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 to use one 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. Table 2 shows correct size
11
Figure 8-1
8.2 Tailstock
8.3 Speed Change
Refer to Figures 8-2 and 8-3:
Loosen locking lever (C) and slide tailstock into
position. Retighten locking lever.
Do not position edge of
tailstock off end of bed. This will reduce
clamping surface and may increase risk of
injury.
To remove tailstock, loosen lever (C) and slide
tailstock off end of bed.
Handle (D) locks and unlocks tailstock quill. (The
handle is adjustable – lift up on handle and rotate it
on pin, then release, making sure it seats itself on
the pin.)
Handwheel (E) advances and retracts quill.
NOTE: If quill is well advanced and won’t respond
to handwheel rotation, push quill toward
handwheel until it engages.
Figure 8-2
The clamping system has been properly adjusted
by the manufacturer. If in the future it does not
properly lock tailstock in position, remove tailstock
from bed, and turn it over. Adjust cam lock nut
(Figure 8-3) as needed.
Refer to Figures 8-4 and 8-5.
The lathe has six speeds, determined by which pair
of pulley steps is chosen. See Figure 8-4. A speed
chart is affixed to the inside of the upper access
door.
Figure 8-4
To move belt to a different pulley:
1. Open upper and lower pulley access doors.
2. Relieve belt tension by pulling handle (F,
Figure 8-5) while pushing up lever (G).
3. Move belt to desired pulley set. Make sure belt
is properly seated in both pulleys, and both
pulleys are aligned (belt is vertical, not
slanted).
4. Push lever (G) down to tighten belt, and close
access doors.
Figure 8-3
Keep access doors closed
during operation.

8.4 Index pin
Refer to Figure 8-6.
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.
Your lathe provides 24 indexing positions. These
are identified by inscribed numbers on the spindle
pulley (H, Figure 8-6)

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 conversation with experienced
woodturners, or consulting books or trade articles.
Above all, simple trial and error will aid in
developing proficiency in the craft.
10.1 Inspection
Before operating the lathe, check that everything is
in proper working order:
1. Machine is on a level surface.
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 support; 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.
See Figure 9-1.
On/off switch: Pull up to start lathe, push down to
stop.
To prevent unauthorized use of lathe, turn it off and
pull out the safety key (A). Store key in a safe
place, inaccessible to children. Key must be
reinserted to start lathe.
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 10-1):
8
13
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.
Spindle Gouges – 1/4", 3/8", 1/2", used to turn
beads, coves and other details.
Deep Fluted Bowl Gouge – 1/4", 3/8" and 1/2",
used for turning bowls & plates.
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.
height. A diamond dresser will keep the wheels
true and eliminate glazing.
Never allow the tool to rest in one place on the
wheel, keep it moving and use a light touch.
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.
10.3 Spindle Turning
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.
Figure 10-2 shows the basic profile shapes in
spindle turning.
Figure 10-1
Basic Turning Tools
For safety and best performance, keep tools s harp.
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.
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
Figure 10-2
10.3.1 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 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.
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.
2. Extremely hard woods may require kerfs cut
into the ends of the stock (Figure 10-3) using a
band saw, so the wood will accept the spur
center and the live center.
14
Figure 10-3
3. Drive the spur center about 1/4” into the
workpiece, using a wood mallet or dead blow
hammer as shown in Figure 10-4. Be careful
that you do not split the workpiece. Never use
a steel face hammer and never drive the
workpiece onto the spur center while it is
mounted in the Lathe spindle.
The tailstock ram is capable of
exerting excessive pressure against the workpiece
and the headstock. Apply only sufficient force with
the tailstock to hold the workpiece securely in
place. Excessive pressure can overheat center
bearings and damage both workpiece and Lathe.
10. Move tool support into position. It should be
parallel to the workpiece, just below the
centerline and approximately 1/8" to 1/4" from
the corners of the workpiece to be turned, as
in Figure 10-5. Tighten support base to Lathe
bed.
Figure 10-5
Figure 10-4
4. Make sure the headstock is locked to the
Lathe bed.
5. Clean the tapered end of the spur center and
the inside of the headstock spindle.
6. Insert the tapered end of the spur center (with
the attached workpiece) into the headstock
spindle.
7. Support the workpiece while bringing the
tailstock into position about 1” away from the
end of the workpiece. Lock the tailstock to the
bed.
8. Advance the tailstock spindle 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.
9. Tighten the spindle locking handle.
11. Rotate workpiece by hand to check for proper
clearance.
12. Start lathe at lowest speed and bring it up to
the appropriate RPM for the size of workpiece
used. Consult the machine’s digital readout.
10.3.2 Cutti ng Techni ques
Roughing Out
1. Begin with a large roughing gouge. Place the
tool on the tool support 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 10-6. Make long sweeping cuts in
a continuous motion to rough the piece down
to a cylinder.
Figure 10-6
15
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.
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).
6. Add details to the workpiece with skew, parting
tool, scraper or spindle gouge.
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.
Coves
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 10-7. Stop
at the bottom; attempting to go up the
opposite side may cause the tool to catch.
"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 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 10-8.
Figure 10-8
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 Off
1. Use parting tool.
2. Adjust lathe speed to lower RPM for parting
through a workpiece.
3. Place tool on tool support and raise the handle
until it starts to cut and continue to cut toward
the center of the workpiece.
4. Loosely hold on to the piece in one hand as it
separates from the waste wood.
Figure 10-7
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.
Sanding and Finishing
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.
16
Turn off the 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.
10.4 Face Plate and Bowl Turning
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.
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.
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.
12 screws. (Phillips and square drive screws
will hold up better than slotted screws. Sheet
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:
5. Make a block the same diameter as the face
plate, Figure 10-9. Both waste block and
workpiece should have flat surfaces for gluing.
be clamped to ensure a good bond. Green
workpieces require cyanoacrylate type glue.
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 firs t
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.
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 accommodate different
size tenons. Most also come with a screw chuck as
well.
Wood Selection
Firewood is the cheapest, most widely available
stock to use while learning to turn bowls. Simply
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.
Checks and Cracks
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.
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.
Figure 10-9
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.
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
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.
17
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. 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.
10.5 Bowl Turning Techniques
To Shape Outside of Bowl
1. Odd shaped burls, crotches and other irregular
shaped blanks require special preparation
before mounting in a chuck or onto a
faceplate. Remove the bark, if there is any,
from what appears to be the center of the top
of the workpiece.
2. Drive spur center into the to p of the workpiece
with a mallet or dead blow hammer.
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.
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.
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.
7. As the bowl takes shape, work on the bottom
(tailstock end) to accomodate attaching a face
plate.
8. Turn a short tenon (about 1/8" long) the size of
the hole in the faceplate. See Figure 10-10.
This will allow centering the workpiece when
the faceplate is attached.
Figure 10-10
(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 sect. 10.4, "Mounting
Stock").
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.
To Shape Interior of Bowl
1. Stop the lathe and move tailstock away. (You
may want to remove the center from the
tailstock to avoid bumping it with your elbow.)
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.
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 10-11.
18
Figure 10-11
6. Use the left hand to control cutting edge of
gouge, while right hand swings tool handle
around toward your body (Figure 10-12). 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
with 1/4" bowl gouge.
9. Begin the separation with a parting tool, but do
not cut all the way through yet.
Sanding and Finishing
1. Remove the tool support and adjust lathe
speed to approximately 500 RPM. High speed
can build friction while sanding and cause heat
check in some woods.
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.
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.
11.0 Maintenance
11.1 General maintenance
Periodically inspect lathe for loose fasteners, worn
electrical cables, proper belt tension, belt wear, or
any other situation that might affect operation or
create a safety risk.
Wipe down the lathe after each use, and blow out
chips and dust using compressed air (wear eye
and respiratory protection!).
Periodically apply a light coat of oil to exposed
metal surfaces: headstock spindle, tailstock quill,
bed surface, and tool rest post. Protect the bed
from rust by applying paste wax or a commercially
available rust protectant.
Bearings are permanently lubricated and sealed.
They do not require further lubrication.
11.2 Belt replacement
Refer to Figures 11-1 through 11-4:
1. Disconnect lathe from power.
2. Release belt tension (see Figure 8-5), and
open pulley access doors.
3. Remove spur center and faceplate.
4. Engage spindle lock, and loosen both set
screws (A, Figure 11-1) in handwheel with
3mm hex key. Unscrew handwheel (B) from
spindle. (Note: Left-hand threads; turn
clockwise to remove.)
5. Disengage spindle lock.
6. Loosen both setscrews (C) in spindle pulley.
Figure 11-1
7. Remove three button head screws to loosen
cover (D, Figure 11-2). NOTE: W hen cover is
loosened, the spindle lock assembly (E) may
pop out with its spring. Be careful not to lose
these parts.
19
Figure 11-2
8. Use a rubber mallet, or hammer against a
block of wood, to tap spindle toward tailstock
(Figure 11-3). Note: The right side bearing will
slide out with the spindle.
Never use a steel face
hammer directly against the spindle.
Figure 11-3
9. Continue pulling spindle toward tailstock until it
clears left hole in headstock and offers enough
room to remove belt (Figure 11-4).
10. Remove belt through lower access door.
11. Reverse above procedure to install belt and reposition spindle.
Figure 11-4
NOTE: Make sure when reinstalling:
• to place cover (D, Figure 11-2) onto
spindle before inserting spindle into
headstock.
• to insert spindle lock with its spring (E,
Figure 11-2) before tightening cover.
• that right-side bearing is properly seated in
its recess in the headstock.
• that spindle pulley is aligned with motor
pulley.
• not to overtighten handwheel.
