CUTTING CROWN MOLDING
Your miter saw is better suited to the task of cutting
crown molding than any tool made. In order to fit prop-
erly, 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°. Most, but not all, crown molding has a top rear angle
(the section that fits flat against the ceiling) of 52° and a
bottom rear angle (the part that fits flat against the wall)
of 38°.
Your miter saw has special pre-set miter detent points at
31.62° left and right for cutting crown molding at the proper
angle (Fig. 27). There is also a mark on the Bevel scale
at 33.85°.
The chart below gives the proper settings for cutting crown
molding. (The numbers for the miter and bevel settings are
very precise and are not easy to accurately set on your
saw.) Since most rooms do not have angles of precisely
90°, you will have to fine tune your settings anyway.

COMPOUND FEATURES
1. Move the left side fence out of the path of the blade
before attempting any of the following cuts.
2. Molding laying with broad back surface down flat on
saw table (Fig. 29).
3. The settings below are for all Standard (U.S.) crown
molding with 52° and 38° angles.

2. Miter table set left 31.62°
3. Save left end of cut
LEFT SIDE, OUTSIDE CORNER:
33.85° 1. Bottom of molding against fence

3. Save right end of cut
RIGHT SIDE, OUTSIDE CORNER:

2. Miter table set right 31.62°
3. Save right end of cut
When setting bevel and miter angles for all compound
miters, remember that:
The angles presented for crown moldings are very
precise and difficult to set exactly. Since they can easily
shift slightly and very few rooms have exactly square
corners, all settings should be tested on scrap molding.

ALTERNATIVE METHOD FOR CUTTING CROWN
MOLDING
Place the molding on the table at an angle between the fence
and the saw table, as shown in Figure 30. Use of the crown
molding fence accessory (DW7084) is highly recommended
because of its degree of accuracy and convenience. The
crown molding fence accessory is available at extra cost
from your local dealer.
The advantage to cutting crown molding using this method
is that no bevel cut is required. Minute changes in the miter
angle can be made without affecting the bevel angle. This
way, when corners other than 90° are encountered, the
saw can be quickly and easily adjusted for them. Use the
crown molding fence accessory (DW7084) to maintain the
angle at which the molding will be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING
ANGLED BETWEEN THE FENCE AND BASE OF
THE SAW FOR ALL CUTS:
1. Angle the molding so the bottom of the molding (part
which goes against the wall when installed) is against the
fence and the top of the molding is resting on the base of
the saw, as shown in Figure 30.
2. The angled “flats” on the back of the molding must rest
squarely on the fence and base of the saw.
