When making a pattern, jig, or fixture, here are
a few things to consider:
1.
Use a material that will smoothly follow the
rub collar or fence.
2.
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.
3.
Make the jig stable, using proven methods
and materials, and fasten the hand holds for
operator comfort and safety.
4.
Secure your workpiece on three sides with
toggle clamps or fasten the workpiece to the
fixture with wood screws. Make sure they do
not protrude through the workpiece.
5.
Ensure that clamps and hidden screws do
not come into contact with the cutter.
6.
Design your fixture so that all cutting occurs
underneath the workpiece.
7.
Always consider the cutting circle and rub
collar diameter for the correct depth of cut
when designing your pattern.
8.
Make sure the workpiece rests flat on the
table, not on the fixture.
9.
Remember, there is tremendous cutting force
on the workpiece. Fixtures must be solid and
stable, and the workpiece must be firmly
secured.
NOTICE
Use care in designing and making fixtures.
Clamps and screws cannot touch the cut-
ter, and the fixtures must be stable in use,
with the workpiece resting on the shaper
table, not on the fixture. The workpiece
must be fixed securely to the jig.

Shop Made
Accessories
Many experienced shaper users regularly use
proven shop-made fences and safety guards to
augment their shaping 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 thick-
ness 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.
Because of the wide range of fences and guards
that can be built in the shop, explaining their con-
struction 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.
