Narrow-Rip Auxiliary Fence & Push Block

There are designs for hundreds of specialty jigs that can be found in books, trade magazines, and 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.

Making a Narrow-Rip Push Block for an Auxiliary Fence

1.Cut a piece of 1⁄2" 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 (see Figure 98).

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.

2.Pre-drill and countersink eight pilot holes 3⁄8" in from the edge of the 5⁜1⁄4" wide board, then secure the boards together with eight #6 x 11⁄2" wood screws, as shown in Figure 99.

3.Using the 1⁄2" material you used in the previ- ous steps, cut out pieces for the push block per the dimensions shown in Figure 100; for the handle, cut a piece 10" long by 5"–9" high and shape it as desired to fit your hand.
