Cutting Crown Molding

In order to fit properly, crown molding must be compound
mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding
are at angles that, when added together, equal exactly 90°.
Most, but not all, crown molding has a top rear angle (the
section that fits flat against the ceiling) of 52° and a bottom
rear angle (the part that fits flat against the wall) of 38°.
Your miter saw has special pre-set miter detent points at
31.6° left and right for cutting crown molding at the proper
angle. There is also a mark on the bevel scale at 33.8°.
The Bevel Setting/Type of Cut chart gives the proper
settings for cutting crown molding. (The numbers for the
miter and bevel settings are very precise and are not easy
to accurately set on your saw.) Since most rooms do not
have angles of precisely 90°, you will have to fine tune your
settings anyway.

nOTE: When setting bevel and miter angles for all
compound miters, remember that the angles presented for

crown moldings are very precise and difficult to set exactly.

Since they can easily shift slightly and very few rooms have
exactly square corners, all settings should be tested on
