An auxiliary fence is used to add support to the cut
off workpiece such as large crown molding flat on
the table (see page 32). It will reduce splintering and
movement of the unsupported cut off piece of wood
after the cut is made.

Making an Auxiliary fence:

Required pieces:
Wood Board (described below)
4 - Flat Head Machine Screws – 1/4" diameter; 3
inches long
4 - 1/4" Flat Washers
4 – Nuts
1. Cut a nominal 1 x 2 inch wood board to a length
of 22-9/16" long. Note: 1 x 2 inch nominal
equals 3/4" x 1-1/2" actual. 3/4" plywood cut to
size may be substituted.
2. Drill 4 holes through the board using a 5/16"
diameter drill bit. Countersink the holes deep
enough so that the flat head screws will rest
below the front work surface – use a 1/2"
diameter drill bit. See figure 3.
propelled at high speed over the fence and beyond
the back of the tool (see Figure 1). Use auxiliary
fence as instructed and shown in figures below.

Remove the sliding fences from the tool – see
page 25.
1. Place the flat head screws through the holes in
the auxiliary fence, then the holes in the stationary
fence on the tool.
2. Place the washers and nuts over the screw
threads and against the stationary fence.
Tighten nuts. See figure 4.

1st Time Use of the Auxiliary fence:

Note: The 1st time the auxiliary fence is used, it will
be cut through by the saw blade – cutting through
creates minimal clearance which reduces splintering
on the workpiece. Set the miter angle and the bevel
angle required before making the first cut. Clamp the
workpiece, then make cut - example: compound
cutting large crown molding flat on the table. See
figure 2.
