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.

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.
