Safety Instructions for the Tenoning Jig
7. ADJUSTING JIG. Unplug the table saw
before installing or adjusting the jig, saw, or
workpiece.
8. TENON MATERIAL SELECTION. Select
clean tenon locations that are low in mois-
ture content, and use workpieces that are
free of knots, staples, nails, and imbedded
stones. Run warped stock through a jointer
before you use the tenoning jig.
9. WORK AREA CLEANLINESS. Keep the
jig and table surface free of wood bits and
tools.
10. ACCESSORIES. Make sure other acces-
sories used on the table saw allow the
tenoning jig to operate freely with unbinding
travel.
11. BLADE GUARD. Reinstall the blade guard
and any other safety features on the table
saw when the tenoning jig is removed and
not used anymore.
12. EXPERIENCING DIFFICULTIES. If at any
time you are experiencing difficulties per-
forming the intended operation, stop using
the machine! Contact Tech Support at
[phone].
1. OPERATION MANUAL. READ and
UNDERSTAND the operation manual for
the table saw before using this jig!
2. KICKBACK. Be familiar with kickback.
Kickback happens when the workpiece is
thrown towards the operator at a high rate
of speed. Until you have a clear under-
standing of kickback and how it occurs, DO
NOT operate the table saw!
3. REACHING OVER SAW BLADE. Never
reach behind or over the blade with either
hand while the saw is running. If kick-
back occurs while reaching over the blade,
hands or arms could be pulled into the
spinning saw blade.
4. OPERATOR POSITION. Never stand or
have any part of your body directly in-line
with the cutting path of the saw blade.
Avoid awkward operations and hand posi-
tions where a sudden slip could cause your
hand to move into the spinning saw blade.
5. SECURING WORKPIECE. ALWAYS
securely clamp the workpiece in the tenon-
ing jig, and MAKE SURE all fasteners are
tight before you make a cut.
6. JIG CONTROL. Hold both tenoning jig
handles firmly when cutting, NEVER hold
the jig with only one hand.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associ-
ated with the Model H7583. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.

The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship-
ment. Remove this protective coating with a sol-
vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For opti-
mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlo-
rine-based solvents, such as acetone or brake
parts cleaner, as they may damage painted sur-
faces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Clean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Lack of ventilation
while using these sol-
vents could cause seri-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.
Always disconnect power
to the machine before
performing adjustments
or maintenance. Failure
to do this may result in
serious personal injury.
The Model H7583 Tenoning Jig is made to oper-
ate in a 3⁄8" x 3⁄4" miter T-slot. If the tenoning jig
operates on a worn or mis-adjusted saw, tenon-
ing results will be poor. Review the following list to
make sure you prepare your saw correctly.
• Table Saw Operation: Make sure that you
read and understand your table saw instruc-
tion manual, and take all safety precautions.
• Saw Blades: Make sure that your saw
blades have no runout and that the teeth are
sharp.
• Saw Adjustments: Make sure that your
table saw blade is perpendicular to the table
and parallel with the miter slots.
• Miter Slot and Table: Make sure the table-
saw miter slots are 3⁄8" x 3⁄4", and the table is
free of burrs and interferences that may bind
the tenoning jig.
• Lighting: Make sure the top of your table
saw has adequate lighting, so the tenoning
jig and workpiece is illuminated without shad-
ows.
Table Saw
Preparation
DO NOT remove the washer from the miter
bar of the tenoning jig. Removal of the
washer will allow the tenoning jig to come
loose during a kickback, possibly causing a
serious personal injury.

Operation Safety
SECTION 3: OPERATIONS
NOTICE
If you have never used this type of jig
before, WE STRONGLY RECOMMEND that
you read books, trade magazines, or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
Overview
Your new tenoning jig features three positive
stops that allow for fast and accurate positioning
of the back stop angle, work support angle, and
work support distance from the blade. This jig is
designed to make tenon cheek cuts only; howev-
er, you can make many special variations to the
basic tenon that is shown in Figures 14 & 15.
Figure 14. Basic tenon.
Figure 15. Typical mortise and tenon.

H7583 Tenoning Jig -15-
2. Plane a wood base stop to the thickness of
the tenoning jig base, and mount it to the
front of the table saw as shown in Figure 17.
The base stop prevents cut off pieces getting
trapped between the saw blade and the work
support plate.
Basic Tenon Cutting
WEAR your safety glass-
es when you perform
any assembly, operation,
and maintenance. Failure
to comply may result in
serious personal injury.
Your new tenoning jig is designed to make tenon
cheek cuts only, and generally, cheek cuts are
made before the shoulder cuts. This procedure
will guide you through three parts; A, B, and C to
show you how to cut your first basic tenon.
A. Preparing the tenoning jig and
workpiece:
Note: The shoulder cuts and angle cuts are made
on the table saw with the miter gauge.
1. Select your mortise and tenon joints, and
draw the cutting lines as shown in Figure 16.
Make sure to account for the thickness of the
saw blade.
—For the strongest joints, select joint loca-
tions that are free of knots and twists.
—Tenons need structural and cosmetic
shoulders to hide gaps that may occur as
the wood shrinks.
—When joining parts of the same thickness,
make the tenon the same thickness as the
tenon walls.
—When joining parts where one piece is
larger than the other, make the tenon as
thick as possible.
—Make the mortise 1⁄8" deeper than the tenon
to allow for the glue to squeeze out.

Stop
3. Cut a wooden spacer block the same thick-
ness as the tenon plus the saw blade. Screw
through the holes in the work support plate to
attach the spacer block (see Figure 18).
Figure 18. Work support spacer block.

-16- H7583 Tenoning Jig
MAKE SURE the blade clearance is adjusted
correctly! DO NOT adjust the work support
plate any closer than 1⁄8" from the saw blade.
If the blade contacts the work support plate,
severe injury may occur. If the blade must
be closer than 1⁄8" for special circumstances,
fasten a block of wood through the holes in
the work support plate to prevent the saw
blade from contacting the jig.
5. Slide the jig back to the base stop, place the
workpiece on the base stop, and clamp the
workpiece against spacer block and back
stop as shown in Figure 20.
4. Cut a back stop backup board and screw it to
the back stop as shown in Figure 19.
Figure 19. Back stop backup board.
6. Slide the jig up next to the saw blade, and use
the major and micro adjustments (Figure 21)
to line up the layout lines on the workpiece
with the saw blade.
Note: The major adjustment sleeve allows
for quick adjustment of the jig positioning,
and the micro adjustment knob fine tunes the
quick adjustment that was made.

B. Cutting Tenon Cheeks:
The tenon uses two styles of cheeks, structural
and cosmetic. In this procedure you will cut the
structural cheeks first, then the cosmetic cheeks.
1. Make sure all jig fixtures, lock levers, and
setscrews are tight and correctly adjusted.
2. Plug the table saw power cord into the power
supply and turn the saw ON.
3. Grasp the jig firmly and slowly slide the jig
toward the saw blade and make the first
structural-cheek cut (see Figure 22). DO
NOT slide the jig quickly toward the saw
blade or the jig can raise up and away from
the table.
4. When the blade exits the workpiece, carefully
and slowly pull the jig back past the blade to
the base stop and turn OFF the saw.
7. Rotate the workpiece so you can now cut the
two cosmetic cheeks.
8. Power up the saw, and make the remain-
ing cosmetic cheek cuts the same way as in
Steps 3 & 4, unplug and turn OFF the saw
(see Figure 24).
Note: For cosmetic cheek cuts, merely rotate
the workpiece 180º instead of using the
spacer block. Cosmetic cheek cut positioning
is not as critical for structural cheek cuts.
5. Remove the spacer block from the work sup-
port base and re-clamp the workpiece.
6. Turn the saw ON and make the second cut
as shown in Figure 23 and turn OFF the
saw.

cosmetic cheek cuts.

C. Cutting Tenon Shoulders:
The final set of cuts are two structural shoulder
cuts and two cosmetic shoulder cuts. In this
procedure you will complete the tenon by using
the table saw fence, a stop block clamped to the
fence, the saw miter gauge, and the base stop.
ALWAYS use a cross-cut saw blade when
making tenon shoulder cuts. Otherwise,
the saw can grab the workpiece causing
machine damage and severe personal
injury!
ALWAYS clamp the fence stop block in
front of the saw blade so the workpiece
will not be trapped between the saw blade
and the fence. When the work piece begins
to be cut, the workpiece must be free from
the stop block. Ignoring this warning may
cause kickback and severe personal injury!
1. Remove the jig from the table saw install a
cross-cut saw blade and the miter gauge.
2. Adjust the saw blade height to cut the tenon
structural shoulder as shown in Figure 25.
Note: When cutting tenon shoulders, avoid
nicking the cheeks of the tenon. Nicks in the
tenons greatly weaken them.
3. Clamp a stop block to the fence face before the
saw blade (Figure 26) and adjust the fence to
cut the structural shoulder. Remember, take
into account the thickness of the blade.

4. Position the workpiece against the miter
gauge (equipped with a backing board) and
the fence stop block.
5. Turn the saw ON, and carefully and slowly
push the miter gauge to cut the structural
shoulder as shown in Figure 26.
6. Turn the saw OFF, and when the blade is
stopped, remove the cut-off piece of wood.
7. Repeat Steps 2-6 to cut the remaining shoul-
ders.
