CUTTING CROWN MOLDING (FIG.
BB,CC)
NOTE: The chart below references a compound
cut for crown molding ONLY WHEN THE ANGLE
BETWEEN THE WALLS EQUALS EXACTLY 90 °.
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.

cut for crown molding ONLY WHEN THE ANGLE
BETWEEN THE WALLS EQUALS EXACTLY 90 °.

When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one changes the other, as well.
