Cutting Crown Molding Angled to the Table and
Fence
The advantage of cutting crown molding in this position is
that no bevel setting is required. Small changes in the
miter angle can be made without affecting the bevel
angle. When using this method the saw can be quickly
and easily adjusted for corners that are not 90° (square).
Making a crown molding support jig
:
A crown molding support jig needs to be constructed to
help hold the molding in place during this cutting opera-
tion.
1. Get a straight piece of wood typically 1/2 inch thick by
23-1/2 inches long (28 inches long if using the table
extension) and approximately 5 inches wide. The
actual width of this piece will depend on overall width
of the crown molding and what the top and bottom
angles are.
2. Drill holes and temporarily mount this piece similar to
building an Auxiliary Fence (see page 21). However,
do not cut the blade slot at this time.
3. Position a piece of crown molding that you are going to
cut so the bottom part (part which is installed against
the wall) is against the wood fence. Make sure the
angles on the crown molding are held firmly against
the wood fence and table of the miter saw. Mark the
height on the fence.
4. Remove the wood fence and cut to this width.
5. Use small nails and glue to attach a top piece (typically
1/2 inch thick by 1-1/2 inches wide by 23-1/2 inches (or
28 inches) long. Make sure the nails are not located
below the sawblade.
6. Securely reattach the completed jig to the miter saw
fence and make a full depth, 45° left and right miter
cut.
Using the crown molding support jig:
1. Position the molding so the bottom (part which is
installed against the wall) is against the wood fence.
2. Use the chart to select the proper miter angle. Tighten
the miter lock knob.
3. Activate switch. Lower head, make the cut. Wait until
the blade comes to a complete stop before allowing the
head assembly to return to the "UP" position and/or
removing the workpiece.
4. ALWAYS PRETEST COMPOUND SETTINGS ON
SCRAP MATERIAL
ANGLE.
