TIPS FOR CUTTING AND SUPPORTING WORKPIECES
TIPS FOR CUTTING CROWN MOLDING
• The two edges of the molding that contact the ceiling and the 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°.
• To accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat
on the mitre table and against the fence.
• The angles for crown moldings must be very precise. The bevel and mitre angles are interdependent; changing one
angle changes the other angle as well.
• Since it is very easy for the work piece to shift, all settings should first be tested on scrap molding. Also most walls
do not have angles of exactly 90°; therefore, you will need to fine-tune your settings.
• When cutting crown molding the bevel angle should be set at 33.85°.
• The mitre angle should be set at 31.62° either right or left, depending on the desired cut for the application. See the
chart below for correct angle settings and correct positioning of crown molding on the work table.
