CUTTING CROWN MOLDING (FIG. 27, 28)
Your compound miter saw is suited for the
dicult task of cutting crown molding. To t
properly, crown molding must be compound-
mitered with extreme accuracy. The two surfaces
on a piece of crown molding that t 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 ts at against the ceiling) of 52°and
a bottom rear angle (the section that ts 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 at on the saw table.
When setting the bevel and miter angles for
compound miters, remember the settings are
interdependent; changing one changes the other,
as well.
NOTE: The chart below references a
compound cut for crown molding ONLY
WHEN THE ANGLE BETWEEN THE WALLS
EQUALS 90°.
