angles that, when added together,
equal exactly 90°.
Most crown molding has a top rear
angle (the section that fits flat against
the ceiling) of 52°and a bottom rear
angle (the section that fits flat against
the wall) of 38°.
In order to accurately cut crown
molding for a 90° inside or outside
corner, lay the molding with its broad
back surface flat on the saw table.
When setting the bevel and miter
angles for compound miters, remember
that the settings are interdependent;
changing one changes the other, as
well.

CUTTING BASE MOLDING (FIG. TT)
Base moldings and many other
moldings can be cut on a compound
miter saw. The setup of the saw
depends on molding characteristics
and application, as shown. Perform
practice cuts on scrap material to
achieve best results:
1. Always make sure moldings rest
firmly against fence and table. Use
hold-down, crown molding vise
or C-clamps, whenever possible,
and place tape on the area being
clamped to avoid marks.
2. Reduce splintering by taping the
cut area prior to making the cut.
Mark the cut line directly on the
tape.
3. Splintering typically happens due to
an incorrect blade application and
thinness of the material.

NOTE: Always perform a dry run cut
so you can determine if the operation
being attempted is possible before
power is applied to the saw.
CUTTING CROWN MOLDING (FIG.
UU, VV)
Your compound miter saw is suited
for the difficult task of cutting crown
molding. To fit properly, crown molding
must be compound-mitered with
extreme accuracy. The two surfaces
