CUTTING CROWN
MOLDING
(FIG. RR, SS)
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 toqether,
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.
