CUTTING CROWN MOLDING

Your miter saw is better suited to the task of cutting crown
molding than any tool made. 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
degrees. Most, but not all, crown molding has a top rear
angle (the section that fits flat against the ceiling) of 52
degrees and a bottom rear angle (the part that fits flat
against the wall) of 38 degrees.
Your miter saw has special pre-set miter latch points at 31.62

degrees left and right for cutting crown molding at the prop-
er angle and bevel stop pawls at 33.85˚ left and right. There
is also a mark on the Bevel scale at 33.85 degrees.
The chart on this page gives the proper settings for cutting
crown molding. (The numbers for the miter and bevel set-
tings are very precise and are not easy to accurately set on
your saw.) Since most rooms do not have angles of pre-
cisely 90 degrees, you will have to fine tune your settings
anyway.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY
IMPORTANT!
