Work Helpers
Before cutting any wood on your saw, study all of the “Basic 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 “helpers”
before starting any projects. Make the “Push Stick” first.
Push Stick and Push Block
Make the Push Stick 1 using a piece of 1 x 2 as shown (Fig. 50).
Make the Push Block 2 using pieces of 3/8” plywood 3 and 3/4"
hardwood 4 (Fig. 51). For proper use of push block (see page 52).
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
sawblade in the event you mistakenly cut into the Push Block.
Position the handle in the center of the plywood 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 74.
Both a push stick or block should be used in the place of the user’s
hand to guide the material only between the fence and blade.
When using a push stick or push block, the trailing 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.
Auxiliary Fence
Make one using pieces of 3/8" plywood 3 and 3/4" hardwood 4.
Fasten together with glue and woodscrews (Fig. 52).
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 53 illustrates dimensions for making a typical featherboard.
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. 53).
