▶ Making Work Helpers

Before cutting any wood on your saw, study
all of the "Basic Table Saw Operations".
Notice that in order to make some of the cuts,
it is necessary to use certain devices, "Work
Helpers", like the Push Stick, the Push Block
and the Auxiliary Fence, which you can make
yourself.
After you have made a few practice cuts,
make these "help ers" before starting any
projects. Make the "Push Stick" first.
▼ MAKING pUSH STICK AND pUSH
BlOCK
Make the Push Stick 1 using a piece of 1 x 2
as shown (Fig. 38). For proper use of Push
Stick see page 30.
Make the Push Block 2 using pieces of 3/8"
plywood 3 and 3/4" hardwood 4 (Fig. 39). For
proper use of push block see page 30.
The small piece of wood, 3/8" x 3/8" x 2-1/2",
should be GLUED to the plywood... DO NOT
USE NAILS. This is to prevent dulling the saw-
blade in the event you mistakenly cut into the
Push Block.
Position the handle in the center of the ply-
wood and fasten together with glue and
woodscrews.
Use a push stick whenever the fence is 2
inches or more from the blade. Use a push
block when the operation is too narrow to
allow the use of a push stick. For proper use,
see page 30.
Both a push stick or block should be used in
the place of the user's hand to guide the ma-
terial only between the fence and blade.
When using a push stick or push block, the trail-
ing end of the board must be square. A push
stick or block against an uneven end could slip
off or push the work away from the fence.

▼ MAKING AUXIlIARY FENCE

Make one using pieces of 3/8" plywood 3 and
3/4" hardwood 4. Fasten together with glue
and woodscrews (Fig. 40).
NOTE: Since the Push Block 2 is used with
the Auxiliary Fence 5, the 4-3/4" dimensions
must be held identical on both the pieces.

▼ MAKING A FEATHERBOARD

Figure 41 illustrates dimensions for making a
typical feather board. It should be made from
a straight piece of wood that is free of knots
or cracks.
Kerf 5 should be about 1/4" apart (Fig. 41).
