Safety Instructions For Power Tools

9. USE PROPER EXTENSION CORD. Make

sure your extension cord is in good condi­tion. Conductor size should be in accor­dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause a
drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten­sion cords if they become damaged.

10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Non-slip footwear
is recommended. Wear protective hair cov­ering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation is
dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT safe­ty glasses.

14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubri­cating and changing accessories.

15. DISCONNECT TOOLS before servicing
and changing accessories, such as blades,
bits, cutters, and the like.

16. REDUCE THE RISK OF UNINTENTION­AL STARTING. Make sure switch is in off

position before plugging in.

17. USE RECOMMENDED ACCESSORIES.

Consult the owner’s manual for recom­mended accessories. The use of improper
accessories may cause risk of injury.

18. CHECK DAMAGED PARTS. Before fur­ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, bind­ing of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.

19. NEVER LEAVE TOOL RUNNING UNAT­TENDED. TURN POWER OFF. Do not

leave tool until it comes to a complete stop.

20. NEVER USE UNDER THE INFLUENCE of
alcohol or drugs, or when tired.

12. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than
using your hand and frees both hands to
operate tool.

13. NEVER OVERREACH. Keep proper foot-

ing and balance at all times.

G8621 Heavy-Duty Sliding Table Shaper -3-

21. NEVER ALLOW UNSUPERVISED OR

UNTRAINED PERSONNEL TO OPER­ATE THE MACHINE. Make sure any

instructions you give in regards to the
operation of the machine are approved,
correct, safe, and clearly understood.

Additional Safety Instructions For Shapers

1. NEVER ALLOW YOUR HANDS to come

within 12 inches of the cutters. Never pass
your hands directly over or in front of the
cutter.

2. BLIND CUT WHENEVER POSSIBLE. This
keeps the knives on the underside of the
workpiece and provides a distance guard
for the operator.

3. WHEN SHAPING CONTOURED WORK

and using a rub collar, NEVER start out at a
corner. See the “Rub Collar” instructions
further on in the manual.

4. WITH THE MACHINE UNPLUGGED,
always rotate the spindle by hand with any
new setup to ensure proper cutter clearance
before starting the machine.

5. DO NOT SHAPE STOCK SHORTER than
12 inches without special fixtures or jigs.
Where practical, shape longer stock and cut
to size.

6. NEVER ATTEMPT to remove too much
material in one pass. You are far more like­ly to enjoy safer and higher quality results if
you allow the cutter to remove material in
multiple passes.

7. THE DANGER OF kickback is increased
when the stock has knots, holes, or foreign
objects in it. Warped stock should be run
through a jointer before attempting to run it
through a shaper.

8. KEEP THE UNUSED PORTION of the cut­ter below the table surface.

9. THE USE OF PUSH STICKS as safety
devices in some applications is smart; in
others it can be quite dangerous. If the push
stick comes in contact with the cutter on the
end grain, it can fly out of your hand like a
bullet—potentially causing serious injury.
We recommend using some type of fixture,
jig, or hold-down device as a safer alterna­tive. Always use the guard as described in
the manual.

10. NEVER FORCE MATERIALS through the
shaper. Let the cutters do the work.
Excessive force is likely to result in poor cut­ting results and will cause dangerous kick­back conditions.

11. ALWAYS ensure that the cutters, fence,
and spindle elevator knob have been tight­ened properly before beginning any opera­tion.

12. ALWAYS feed the work toward the cutters
in the direction opposite of the cutter rota­tion. Also, using and maintaining a sharp
cutterhead will greatly reduce the chance of
kickback.

13. NEVER REACH BEHIND CUTTER to grab
the workpiece. Your hand may suddenly be
pulled into the cutter in the event of a kick­back.

14. IF AT ANY TIME YOU ARE EXPERIENC­ING DIFFICULTIES PERFORMING THE
INTENDED OPERATION, STOP USING
THE SHAPER! Then contact our service

department or ask a qualified expert how
the operation should be performed.

Like all power tools, there is danger associ­ated with shapers. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this tool with respect and cau­tion to lessen the possibility of operator
injury. If normal safety precautions are over­looked or ignored, serious personal injury
may occur.

-4- G8621 Heavy-Duty Sliding Table Shaper

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 personal
injury, damage to equipment or poor work
results.

SECTION 2: CIRCUIT REQUIREMENTS

220V Operation

The Model G8621 Shaper is furnished with a
3450 R.P.M., 5 H.P., Single-Phase 220V motor,
push-button ON/OFF magnetic starter switch, for­ward-reverse switch and a cord set. Under nor­mal use, the motor draws approximately 25 amps
@ 220V. We recommend a 30 amp circuit break­er. If frequent circuit failures occur when using the
shaper, contact our service department.

The shaper motor must be connected to its own
dedicated 30A circuit. The shaper should not
share a circuit with any other machine, and the
wires in the circuit should be rated for 30A. A
standard 2-pole breaker is also necessary for use
with the shaper.

We recommend using a NEMA-style L6-30 plug
and outlet similar to that in Figure 1. You may
also “hard-wire” the shaper directly to your panel,
provided you place a disconnect near the
machine. Check the electrical codes in your area
for specifics on wiring requirements.

Grounding

In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur­rent. This tool is equipped with an electric cord
that has an equipment-grounding conductor
which must be properly connected to 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.

Improper connections of the electrical-grounding
conductor can result in the risk of electric shock.
The conductor with green or green and yellow
striped insulation is the electrical-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.

This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir­cumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.

G8621 Heavy-Duty Sliding Table Shaper -5-

Extension Cords

Wiring

We do not recommend the use of extension
cords on 220V equipment. Arrange the place­ment of your equipment and the installed wiring
to eliminate the need for extension cords. Should
it be necessary to use an extension make sure
the cord is rated Hard Service (grade S) or bet­ter. Refer to the chart in Section 1: Safety to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin. Always repair or
replace extension cords when they become worn
or damaged.

A wiring diagram is provided at the back of this
manual should it be necessary to repair or revise
the wiring. Always utilize a qualified electrician
when doing any electrical work on this equip­ment.

We have covered some basic electrical
requirements for the safe operation of
your machine. These requirements are not
necessarily comprehensive. You must be
sure that your particular electrical configu­ration complies with local and state codes.
Ensure compliance by checking with your
local municipality or a licensed electrician.

Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship­ment. Remove this protective coating with a sol­vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. Avoid chlorine­based solvents as they may damage painted sur­faces should they come in contact. Always follow
the usage instructions on the product you choose
to clean.

Do not use gasoline or
other petroleum-based
solvents to clean with.
They have low flash
points which make them
extremely flammable. A
risk of explosion and
burning exists if these
products are used.
Serious personal injury
may occur.

FLOOR LOAD

Your Model G8621 Shaper represents a moder­ately large weight load in a moderate sized foot­print. Most commercial shop floors will be ade­quate for the 770 lb. weight of the Model G8621.
Some floors may require additional support.
Contact an architect or structural engineer if you
have any question about the ability of your floor to
handle the weight.

WORKING CLEARANCES

Working clearances can be thought of as the dis­tances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands and/or work tables. Also consider the rel­ative position of each machine to one another for
efficient material handling. Be sure to allow your­self sufficient room to safely run your machines in
any foreseeable operation.

Do not smoke while using
solvents. A risk of explo­sion or fire exists and may
result in serious personal
injury.

Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest­ed. Always work in well­ventilated areas far from
potential ignition sources
when dealing with sol­vents. Use care when dis­posing of waste rags and
towels to be sure they do
not create fire or environ­mental hazards.

LIGHTING AND OUTLETS

Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or exten­sion cords are not obstructing high-traffic areas.
Be sure to observe local electrical codes for prop­er installation of new lighting, outlets, or circuits.

Make your shop “child safe.”
Ensure that your workplace
is inaccessible to children by
closing and locking all
entrances when you are
away. Never allow visitors in
your shop when assembling,
adjusting, or operating
equipment.

-10- G8621 Heavy-Duty Sliding Table Shaper

SECTION 4: ASSEMBLY

Beginning Assembly

Most of your Model G8621 Shaper has been
assembled at the factory, but some parts must be
assembled or installed after delivery. We have
organized the assembly process into steps.
Please follow along in the order presented here.

Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.

Disconnect power to the
machine when perform­ing any maintenance or
assembly. Failure to do
this may result in serious
personal injury.

Handwheel

The handwheel, pre-installed at the factory, is
made of cast iron. It is used to raise and lower the
spindle to accommodate the height required by
your cutter.

Thread the crank handle onto the handwheel.

Wear safety glasses dur­ing the entire assembly
process. Failure to com­ply may result in serious
personal injury.

Some metal parts may
have sharp edges on
them after they are
formed. Please examine
the edges of all metal
parts before handling
them. Failure to do so
could result in injury.

table, depending on the type of desired cut or cut­ting direction. To mount the miter gauge and its
fence:

1. Locate the threaded holes on either side of
the table.

2. Install the push shaft as shown in Figure 19.

another person. Loosen the four bolts that
attach the motor to the motor base. One per­son should slide the motor either up or down
while the other person measures the align­ment of the motor pulley and the spindle pul­ley with a straightedge.

Pulleys & V-Belt

Improper pulley alignment sharply reduces the
effectiveness of power transmission and belt life
expectancy. To align the pulleys:

1. Remove the motor cover from the back of
the shaper cabinet to expose the motor and
pulleys.

2. Check the alignment with a straightedge. If
the pulleys are in alignment, the straightedge
should touch two sides of each pulley even­ly as in Figure 25.

3. If the pulleys are parallel with each other, but
not in-line, the motor needs to be adjusted.

5. When the motor pulley and the spindle pulley
alignment are correct, tighten the motor to
the motor base.

6. Inspect your results. If satisfactory, double­check that the mounting bolts are tight.

7. You can also make small adjustments in the
motor pulley alignment by raising or lowering
it along the motor shaft. To do this, loosen
the two setscrews (one is shown in Figure

25) which are in the lowest groove of the
motor pulley and move the pulley into posi­tion. Tighten the setscrews when the align­ment is satisfactory.

-18- G8621 Heavy-Duty Sliding Table Shaper

V-Belt Tension

Speed Changes

You should be able to deflect the belt 1⁄4" with
moderate finger pressure. This may seem tight
compared to most other V-belts, but since the belt
is small and runs fast, this amount of tension is
necessary. The V-belt will slip if too loose, and
will squeal or cause vibration if too tight. Adjust
the tension if necessary. To adjust V-belt tension:

1. Make sure the pulleys are properly aligned.

2. Loosen the two motor mount plate bolts and

slide the motor left or right to modify the belt
tension. Keep the pulleys aligned.

3. Tighten the motor mount plate bolts, test the
tension, and check the pulleys.

4. Repeat steps 2-3 until tension is correct and
the pulleys are aligned.

Disconnect power to the
machine when perform­ing any adjustments or
maintenance. Failure to
do this may result in seri­ous personal injury.

The Model G8621 Shaper is equipped with a V­belt drive system that controls the speeds. To
change spindle speeds:

1. Unplug the machine.

2. Loosen the two motor plate bolts, and slide

the motor toward the spindle assembly. DO
NOT take the bolts out.

3. Select the desired speed. There are four
speeds: 3600 R.P.M., 5100 R.P.M., 8000
R.P.M., 10,000 R.P.M. Figure 26 shows the
belt positions for each available speed.

Figure 26. Spindle speed adjustment.

4. Align the belt along the appropriate pulley

grooves.

5. Slide the motor back into position and tight­en the belt. When the belt is properly ten­sioned, there should be approximately
deflection in the center of the belt when you
press it with moderate pressure.

6. Tighten all the adjusting bolts.

7. Spin the pulley to ensure proper tracking.

Fence Adjustment

Aligning The Fences

The fence is a two-piece adjusting system. Each
fence is independently adjustable to compensate
for different cutting thicknesses and special shap­ing applications. Without any play, one turn of the
knob moves the split fence approximately
(.078"). To adjust the fence:

1. Loosen the fence lock handle.

2. Turn the fence adjustment knob until the

fence is set to the desired position.

3. Tighten the fence lock handle.

More detailed information concerning fence
adjustments is covered in the “Straight Shaping”
instructions.

⁄64"

The following procedure ensures that the fence is
parallel with itself and square with the table.

1. Check that the bolts through the wood facing
are tight on each side and are adequately
countersunk.

2. To align the wood facing, adjust one or both
fence halves so they are in close alignment.
Micro-adjust and check the alignment with a
straightedge as shown in Figure 27.

3. If the wood fences are not parallel with each
other, shim the incorrect side with electrical
washers. Normal washers may work, but
electrical washers allow for fine adjustments.

Table Inserts

Setting Miter Gauge

The Model G8621 is supplied with two inserts
which provide three possible opening diameters
in the shaper table surface. Use the smallest
opening that a particular cutter will allow. This
offers more support for the workpiece and
reduces the amount of chips that can fall into the
machine. The correct spindle opening also allows
any unused portion of the cutter to remain below
the table surface—increasing operator protection.

The cast iron table insert must be flush with the
top of the table. To adjust the insert:

1. Remove the three Phillips
hold the cast iron insert in place.

2. By using a straightedge and a screwdriver,
turn the barrel screws clockwise or counter­clockwise to level the cast iron insert with the
table. See Figure 28.

It is necessary to square the miter gauge each
time it is removed from the table. To do this:

1. Ensure that the fence halves are aligned and
that the miter assembly is correctly assem­bled.

2. Place one end of a framing or try square
flush with the infeed shaper fence.

3. Rotate the miter gauge so that it lines up
flush with the other end of the square.

4. Set the miter gauge pointer to 0° and tighten
the setscrew as shown in Figure 29.

infeed and outfeed fences during this move­ment. If this is the case, proceed to the next
section. If they do not stay flush or are not
square to the miter fence, repeat steps 1-4
until they are true.

Test Run

Once assembly is complete and adjustments are
done to your satisfaction, you are ready to start
the machine.

DO NOT have a cutter installed when you test run
the shaper. Turn on the power supply at the main

panel. Press the ON button. Make sure that your
finger is poised on the OFF button, just in case

there is a problem. The shaper should run
smoothly with little or no vibration or rubbing nois­es. Strange or unnatural noises should be inves­tigated and corrected before operating the
machine further.

If the shaper seems to be running correctly,
check the directional switch. The spindle should
be rotating in a counterclockwise direction when

the switch is in the FWD position. Run the Model

G8621 for a short time to ensure that the moving
parts are working properly with no excessive
vibration. If any problem develops, correct it
before attempting to use the machine.

Disconnect power to the
machine when perform­ing any adjustments or
maintenance. Failure to
do this may result in seri­ous personal injury.

Never use the Model G8621 for applications
other than those for which it was intended.
DO NOT overload the machine or use
excessive force when shaping materials.
Severe personal injury, damage to the
machine, or damage to your workpiece
could occur.

If you cannot locate the source of unusual noises,
immediately contact our service department for
help.

SECTION 6: OPERATIONS

Rotation

Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.

Disconnect power to the
machine when perform­ing any adjustments or
maintenance. Failure to
do this may result in seri­ous personal injury.

Wear safety glasses dur­ing all operations on the
shaper. Failure to com­ply may result in serious
personal injury.

Your shaper is equipped with a
FORWARD/REVERSE switch as shown in
Figure 30. In many instances, you will need to flip
the cutter over and reverse cutter rotation.
Whenever possible, mount the cutter so the
board is milled on the bottom side. This method
does a better job and is safer for the operator.

Always check the direction of cutter rota­tion before beginning any shaping opera­tion, and always feed the work against the
direction of the cutter rotation.

Always wear a dust
mask when operating
the shaper. Using this
machine produces saw­dust which may cause
allergic reactions or res­piratory problems.

Figure 30. FORWARD/REVERSE switch.

NOTICE

The following section was designed to give
instructions on the basic operations of this
shaper. However, it is in no way compre­hensive of every shaper application. There
are many different jigs that can be built to
increase safety, accuracy, and types of
cuts. WE STRONGLY RECOMMEND that
you read books, trade magazines, or get for­mal training to maximize the potential of
your shaper.

NOTICE

Cutter Installation

Table Lock

Your shaper operates at speeds of 3600, 5100,
8000 and 10,000 R.P.M. 3
must be operated at the slowest speed.

Always use the largest spindle size possible, and
never use more than one bushing size to gain two
spindle sizes. ”Stacking” two cutter bushings to
decrease the inside diameter of the cutter will
cause the cutter to perform incorrectly when
placed under a load.

1. Unplug the shaper.

2. Place an appropriate spacer or collar at the

base of the spindle for support. Place the
cutter on the spindle, making sure the rota­tion is correct for your application.

3. Use spacers or collars to suit your particular
application, then place the spindle washer
under the nut. Screw on the nut and locknut.

4. Tighten the nuts while holding the spindle
stationary. Use a wrench on the notches at
the top of the spindle for leverage as shown
in Figure 31.

⁄2" or larger cutters

The sliding table works with the clamping miter
gauge to allow you to secure your workpiece to
the table and make the cut by sliding the table.
This feature greatly increases operator safety
because it keeps hands away from the cutter­head.

When the sliding operation is not desired, the
table lock shown in Figure 32 will make the table
stationary. Simply pull the knurled shaft and twist
it so the cross pins slide into the largest slots in
the housing. If you want to unlock the table, pull
the shaft, twist it, and place the cross pins in the
smallest slot.

The sliding table makes it easy to feed the
work into the cutter at a faster rate than
would normally be used. Always feed the

work slow and steady to avoid kickback
and to achieve smooth results with your
work. Although the miter assembly does
aid in safety, common sense should always
be used during every shaping operation.

Spindle Height

To adjust the cutter height:

Straight Shaping

1. Loosen the spindle lock shown in Figure 33.

2. Move the spindle up or down with the hand-

wheel until the desired position is obtained.

3. Lock the spindle into position.

Read the entire manual
before making any cuts
with your shaper.
Serious personal injury
may result if safety or
operational information
is not understood or fol­lowed.

The fence assembly is a two-piece, independent­ly adjustable system. When removing material
from the whole face of your workpiece, the out­feed fence can be adjusted to provide support
for the workpiece as it passes over the cutter.
The outfeed fence can also be set in-line for par­tial face removal.

If removing material from the whole face,
observe the following steps:

1. Loosen the locking handles shown in Figure
34 that hold the fences in place.

Figure 33. Location of spindle lock.

NOTICE

The lock knob keeps the spindle in a fixed
position during shaper operation. Do not
over-tighten the lock knob. A snug fit is all
that is needed to keep the spindle from
moving during shaper operation.

Disconnect power to the
machine when perform­ing any adjustments or
maintenance. Failure to
do this may result in seri­ous personal injury.

Figure 34. Location of fence locking handles.

2. Adjust the infeed fence by turning the adjust-

ment knobs until the workpiece contacts the
cutter in the desired location.

3. Lock the infeed fence in position with the

locking handle. Use a test piece to determine
the best setting.

4. Loosen the mounting screws on the fence
faces and set the face ends to barely clear
the cutter. This allows the maximum support
possible for the workpiece while passing the
cutter. Remember to tighten the wood facing
before starting the shaper.

5. A test sample of the desired cut should be
advanced about 8'' then stopped.

6. Once the shaper is turned off and the cutter
has come to a complete stop, adjust the out­feed fence to support the new profiled edge.

See Figure 35.

4. Run a test piece through the shaper as
shown in Figure 36.

Figure 36. Fence adjustment for blind cuts.

5. Always cut the end grain first when putting

an edge around the perimeter of your work­piece. See Figure 37.

Figure 35. Fence adjusted to support workpiece.

If the face of the workpiece will only be par­tially removed, observe the following steps:

1. Adjust the infeed fence to approximately the

desired depth of cut. Lock the infeed fence in
place.

Figure 37. Sequence for multiple cuts.

2. Use a straightedge to adjust the outfeed

fence to the same plane as the infeed. Lock
the outfeed fence in place.

3. Set the right and left wood face ends so they
barely clear the cutter. This allows the maxi­mum support possible for the workpiece
while passing the cutter. Remember to tight­en down the wood facing before starting the
shaper.

-26- G8621 Heavy-Duty Sliding Table Shaper

Rub Collars

Rub collars are used when shaping curved or
irregular workpieces, such as arched doors or
round table tops. Rub collars also limit the depth
of your cut.

There are two types of rub collars—solid and ball­bearing. We recommend against the use of solid
rub collars. Grizzly carries an extensive line of
ball bearing rub collars designed for use with
Grizzly shapers. See the current catalog for list­ings.

Rub collars may be used in any of the following
positions:

1. Rub collar below the cutter: When the rub
collar is used below the cutter as shown in
Figure 38, the progress of the cut can be
observed. However, any unintentional move­ment may lift the workpiece into the cutter,
damaging your work and creating a danger­ous situation that may result in kickback. We
do not recommend using the rub collar below
the cutter.

2. Above the cutter: When the rub collar is
used above the cutter as seen in Figure 39,
the cut cannot be seen. This offers some
advantage: the stock is not affected by slight
variations in thickness and accidental lifting
will not damage the workpiece. If lifting
occurs, simply correct the mistake by repeat­ing the operation.

Figure 39. Rub collar installed above cutter.

3. Between two cutters: Using a rub collar

between two cutters, as in Figure 40, has
the distinct advantage of performing two cuts
at once or eliminating the need to change
cutters for two different operations. Notice
that part of the edge is left uncut. The uncut
portion rides on the rub collar.

Figure 38. Rub collar installed below cutter.

Whenever the cutterhead is above the
workpiece, or you can see it spinning dur­ing use, you must take extreme caution to
keep your hands away from the cutterhead.
Failure to do so may cause serious per­sonal injury.

G8621 Heavy-Duty Sliding Table Shaper -27-

Figure 40. Rub collar between two cutters.

Pattern Work

2. Make the jig stable, using proven methods

and materials, and fasten the hand holds for
operator comfort and safety.

When using a pattern, the rub collar can be posi­tioned either above, below or between cutters.

The pattern is usually used when the entire edge
is to be shaped or when many duplicate pieces
are needed. Pattern work is particularly useful
when rough cutting irregular or oversize pieces
and then shaping the edge in a simple two-step
operation. A pattern can be incorporated into a jig
by way of adding toggle clamps, hand holds or
other safety devices.

You have greater flexibility when choosing the
correct diameter rub collar for pattern work than
for non-pattern work. If you look at Figure 41, you
will notice that the position of the pattern deter­mines the depth of cut. In other words, your pat­tern size is dependent upon the interrelationship
of the cutting circle, the desired amount of mate­rial removed, and the rub collar size. Changing
one or more of these will change the amount of
material removed. Planning ahead, you can most
effectively decide which rub collars are best suit­ed for your application.

3. Secure your workpiece on the three sides
that will not be cut with toggle clamps, or fas­ten the workpiece to the jig with wood
screws.

4. Ensure that clamps and hidden screws do
not come into contact with the cutter.

5. Design your jig so that all cutting occurs
underneath the workpiece as shown in
Figure 42. Notice the operator is not
exposed to the cutting edge of the cutter!

6. Always consider the cutting circle and rub
collar diameter for the correct cutting depth
when designing your pattern.

7. Make sure the workpiece rests flat on the
table, not on the fixture.

Workpieces must be solid, stable, and
secured to the jig; or kickback may occur,
causing personal injury.

Pattern

Figure 41. Rub collar determines depth of cut.

When making a pattern jig here are a few things
to consider:

1. Build your jig from a material that will
smoothly follow the rub collar or fence.

Rub Collar

Workpiece fits here

Figure 42. Pattern jig for making curved pieces.

Irregular or freehand shaping takes a high degree
of skill and dexterity. The fence assembly is not
used during irregular shaping, so rub collars must
be used. Also, unless your jig is designed to
touch the rub collar before contacting the blade, a
starting fixture must be used to begin your cut.

-28- G8621 Heavy-Duty Sliding Table Shaper

About starting fixtures:

The purpose of the starting fixture is to support
the workpiece during the beginning of the cut.
The workpiece is typically placed in the starting
position using the starting fixture for support,
Then swung into the cutter while holding the
workpiece firmly against the starting fixture. After
the cut has been started, the work is swung away
from the starting fixture and is supported only by
the rub collar. Always feed against the rotation

of the cutter and do not start cuts at corners.

To use your pattern jig:

Miter Assembly

When the workpiece is clamped to the table using
the miter assembly, crosscuts can be made with
a much greater degree of safety. The miter gauge
can be adjusted to 60° in both directions. Figure
43 shows the miter gauge set to 0° and Figure 44
shows it at 45°. To adjust the miter fence:

1. Loosen the miter gauge with the adjustment
handle.

1. Remove the fence assembly. Choose the
appropriate cutter and rub collar for your
application and lock them in place. Secure
your workpiece to the pattern jig.

2. Check cutter rotation, and adjust the spindle
height to align the cutter to your workpiece.
Clamp a starting fixture to the table surface,
using the location that best supports your
work.

3. If everything is correct and the cutter is tight.
Turn the shaper on.

4. Place your jig/workpiece against the starting
fixture. Using firm pressure, pivot the work­piece into the cutter and make sure the jig is
touching the rub collar. Keep your jig in con­tact with the rub collar and slowly follow the
pattern, moving against the cutter rotation.

2. Assuming that you have performed the steps
in the “Setting Miter Gauge” instructions, turn
the miter gauge in the desired direction so
the pointer indicates the angle, and tighten
the miter gauge with the adjustment handle.

Figure 43. Miter gauge set to 0°

(fences opened for clarity).

Freehand Shaping

Freehand methods are one of the most dan­gerous operations performed on a shaper.

Although this machine is capable of performing
freehand operations, we do not recommend that
you attempt to do so. If you MUST perform free­hand operations, get formal training and read a
book that details freehand operations, their inher­ent dangers, and ways to avoid those dangers!

G8621 Heavy-Duty Sliding Table Shaper -29-

Figure 44. Miter gauge set to 45°

(fences opened for clarity).

The miter fence can be adjusted by loosening
the two bolts that hold it to the miter gauge and
then sliding it in the desired direction.

Shaper Accessories

The support fence slides up and down the miter

fence and can be locked to hold the back of the
workpiece in place.

The miter clamp holds the workpiece firm
against the table and keeps it in position against
all of the associated fences.

To use the miter assembly:

1. Determine the angle of cut and set the miter
gauge to that angle, without tightening it yet.
(The angle of the miter gauge should be
determined by the angle of the workpiece
you are about to shape.) Lock the miter
gauge in place.

2. Move the infeed and outfeed fences out of
the way. Hold the workpiece flush against
the miter fence and slide the workpiece and
table toward the cutter. Line the workpiece
up with the cutter.

3. Slide the support fence to the back of the
workpiece and lock in place.

4. Clamp the workpiece to the table with the
miter clamp as shown in Figure 45.

5. The workpiece is now ready for the cut.

There are many accessories that can be built or
purchased to increase the safety of the operator.
Many experienced shaper users regularly use
proven shop-made fences and safety guards to
augment their shaping operations. In addition,
many production shops routinely use power feed­ers with their shapers to streamline their opera­tions.

Here are some basic accessories and their uses:

• Zero Clearance Fence — A shop-made
fence with an opening only as large as the
cutter, so that only the part of the cutter
being used is exposed.

• Box Fence — A shop-made box that com-
pletely surrounds the cutter. A one-piece
fence is attached that allows only the thick­ness of the board to pass underneath, there­by completely shielding the operator from
exposure to the spinning cutter. A clear plex­iglass window on top of the box allows the
operator to view the workpiece during cut­ting.

• Power Feeder — A motorized unit that can
be clamped or permanently mounted to the
table of a shaper. A power feeder pulls the
workpiece through the cut, reducing the risk
of operator contact with the spinning cutter
and reducing any injuries due to kickback.
Because of the steady feed rate, power feed­ers can also produce cleaner, more consis­tent cuts. Check the current Grizzly catalog
for available power feeders.

Because of the wide range of fences and guards
that can be built in the shop, explaining their con­struction is beyond the scope of this manual. We
strongly recommend that you read shaper books,
trade magazines, or get formal training to learn
more about these.

universal, Grizzly reminds you that each work­shop is different and safety rules should be con­sidered as they apply to your specific situation.

Operating this equipment has the potential
for flying debris to cause eye injury. Always
wear safety glasses or goggles when oper­ating equipment. Everyday glasses or read­ing glasses only have impact resistant lens­es, they are not safety glasses. Be certain
the safety glasses you wear meet the appro­priate standards of the American National
Standards Institute (ANSI).

Like all power tools, there is danger associ­ated with the Model G8621 Shaper.
Accidents are frequently caused by lack of
familiarity or failure to pay attention. Use
this tool with respect and caution to lessen
the possibility of operator injury. If normal
safety precautions are overlooked or
ignored, serious personal injury may occur.
