CUTTING CROWN MOLDING
(FIG. HH, II)
Your compound miter saw is suited
for the diffi cult task of cutting crown
molding. To fi t properly, crown molding
must be compound-mitered with
extreme accuracy. The two surfaces
on a piece of crown molding that fi t
fl at 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 fi ts fl at against
the ceiling) of 52°and a bottom rear
angle (the section that fi ts fl at 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 fl at 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.
