CUTTINGCROWNMOLDING(FIG. AA,BB)
NOTE: The chart below references s compound
cut for crown motding ONLY WHEN THE ANGLE
BETWEEN THE WALLS EQUALS EXACTLY 90 °.
Your compound miter saw issuited 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
fiat 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 fiat against the ceiling) of 52°and a bottom rear
angle (the section that fits fiat against the wall) of 38°.
tn order to accurately cut crown molding for s 90°
inside or outside corner, lay the molding with itsbroad
back surface fiat 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 Also keep in
mind that the angles from crown molding are very easy
for these angles to shift slightly, al! settings should be
tested on scrap molding.
