TIPS FOR CUTTING AND SUPPORTING WORKPIECES
• 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.

2. Mitre table set right 31.62°
3. Save left end of cut
