CUTTING CROWN MOLDING
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 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.
Settings that follow are for standard crown molding lying flat on compound
miter saw table (as in fig 20):
