Narrow-Rip Auxiliary
Fence & Push Block
There are designs for hundreds of specialty jigs
that can be found in books, trade magazines, and
on the internet. These types of jigs can greatly
improve the safety and consistency of cuts. They
are particularly 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 made to increase the
safety of very narrow rip cuts.

Note: We recommend cutting hardwood
board oversize, then jointing and planing it
to correct size to make sure board is square
and flat. Only use furniture-grade plywood or
kiln-dried hardwood to prevent warping.
2.
Pre-drill and countersink eight pilot holes
from bottom of 3" wide board, then secure
boards together with eight #8 x 1
screws, as shown in Figure 92.
