Cutting Crown Molding

• Crown molding cuts must be positioned properly to
fit exactly.
• There are two ways to cut crown molding: flat on
table or angled to table and fence.
• Crown molding's "spring angle" is the angle
between the back of the molding and the bottom flat
surface that fits against the wall.
• This miter saw has special miter detents at
31.6° and bevel detents at 33.9°. These
detents allow you to easily position most crown
moldings flat on the table and make precise cuts
for 90° corners. (These detents are only for use
with crown moldings that have a 38° "spring

• See also pages 25 and 26 for miter and bevel angle
charts for cutting crown moldings that have
38° and 45° spring angles (and the material is
laid flat on the miter saw base).
• Even though these angles are standards, most
rooms do not have angles of exactly 90°, therefore,
you will often need to fine tune your settings.
The

angles and corner angles, then automatically deter-

necessary to make each crown molding cut fit
perfectly.
