Note: We recommend cutting the hardwood
board oversize, then jointing and planing it
to the correct size to make sure the board
is square and flat. Only use furniture-grade
plywood or kiln dried hardwood to prevent
warping.

Making a Narrow-Rip push Block for
an Auxiliary Fence
1. Cut a piece of 3⁄4" thick plywood 5
1⁄4" wide and
as long as your table saw fence; cut a piece
of 3⁄4" thick hardwood 3" wide and as long as
your table saw fence, as shown in Figure
84.
Narrow-Rip Auxiliary Fence & push Blockthere are designs for hundreds of specialty jigs
that can be found in books, trade magazines, and
on the internet. these t ypes of jigs can greatly
improve the safety and consistency of cuts. they
are particularl y useful during production runs
when dozens or hundreds of the same type of cut
need to be made.
the narrow-rip auxiliary fence and push block
system shown in this section is an example of
a specialty jig that can be m ade to increase the
safety of very narrow rip cuts.
2. pre-drill and countersink eight pilot holes 3⁄8"
from the bottom of the 3" wide board, then
secure the boards together with eight #8 x
11⁄2" wood screws, as shown in Figure 85.

3. using the 3⁄4" material you used in the previ-

the handle, cut a piece 10" long by 5"–9" high
and shape it as desired to fit your hand.
4. attach the handle to the base with #8 x 11⁄2"
wood screws, and attach the lip to the base
with cyanoacrylate type wood glue.
