CUTTING BASE MOLDING (FIG. AA)
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 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 cut. Mark cut line directly on the
tape.
3. Splintering typically happens due to wrong
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. BB, CC)
Your compound miter saw is suited for the
difficult task of cutting crown molding. To fit
properly, crown molding must be compound-
miterd with extreme accuracy.
The two surfaces on a piece of crown molding
that fit flat against the ceiling and wall are at
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.
