Crown Molding Auxiliary Fence
When making a compound
cut on a molding lying flat
on the table, narrow cut-off pieces, 2" (50mm)
or less in width, may be propelled at high
speed over the fence and beyond the back of
the tool (Fig. 59). Use auxiliary fence (Fig. 60)
as instructed below.
An auxiliary fence (Fig. 60) is used to add sup-
Fig. 59
port to the cut-off workpiece such as large
crown molding when cut flat on the table (Fig.
59, 22). 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" diam-
eter (M6); 2-1/2" (65mm) long
• 4 – 1/4" (M6) Flat Washers
• 4 – Nuts
To make an auxiliary fence:
1. Cut a nominal 1" x 2" wood board to a length
of 26-1/16" (662mm) long.
NOTE: 1" x 2" nominal equals 3/4" x 1-1/2"
(19x38mm) actual. 3/4" (19mm) plywood
cut to size may be substituted.
2. Drill four holes through the board using a
5/16" (8mm) 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" (13mm) diameter drill bit (Fig.
61).
3. Remove the saw's sliding fences. See "Slid-
ing Fences" on page 32.
4. Place the flat head screws through the holes
in the auxiliary fence, then the holes in the
stationary fence on the tool.
5. Place the washers and nuts over the screw
threads and against the stationary fence.
Tighten nuts.
