Crown Molding Auxiliary Fence - Bosch GCM18V-12GDC Operating/Safety Instructions Manual

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 (see Fig.
59). Use auxiliary fence as instructed and shown in
figures below.
An auxiliary fence is used to add support to the cut-off
workpiece such as large crown molding when cut flat
on the table (see Fig. 60). 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 (M6);
2-1/2" (65mm) long
4 – 1/4" (M6) Flat Washers
4 – Nuts
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 (see Fig. 61).
Remove the sliding fences from the tool – see page 38.
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.

FIRST-TIME USE OF THE AUXILIARY FENCE:
NOTE: The first time the auxiliary fence is used, it will
be cut through by the saw blade – cutting through cre-
ates minimal clearance which reduces splintering on
the workpiece. Set the miter angle and the bevel angle
required before making the first cut.
with the saw Off by conducting a simulated cutting
cycle, and observe the projected path of the saw
blade. Keep hands at least six (6) inches (152mm)
away from the projected path of the saw blade.
Clamp the workpiece, then make cut – example: com-
pound cutting large crown molding flat on the table (see
Fig. 58).
