IX. Operation (continued)
The two cut surfaces of the mitred moulding
must add to a 90° angle. Most crown
moulding has a top angle of 52° that fits flat
on the ceiling, and a bottom rear angle of
38° that fits flat against the wall.
CUTTING BASE MOULDING (FIG. 37)
Base mouldings and trims can be cut
on a compound mitre saw. The method
depends on the type of moulding,
its characteristics and applications.
1. Use vise clamps, hold-down or
C-clamps whenever possible. Place
tape on the area being clamped to
avoid marking the finish surface of the
moulding.

2. Tape the area being cut to avoid splintering, and mark the cut line on the tape.
3. Perform practice cuts on scrap pieces before cutting the final moulding.
NOTE: Splintering may be caused due to the thinness of the moulding or use of the wrong
type of blade.

1. If the crown moulding is thin and cannot
stand vertically on edge, lay the moulding
flat with its widest back surface flat on
the saw table. (Fig. 38)
2. To avoid splintering and marking, tape
the cutting line and any surface that is
being clamped.
3. The angle settings for the two pieces of
moulding that will be adjoining in any one
corner, will be interdependent with each
other. Any change in the setting for one
side must be equally compensated for on
the other side.
4. All settings should be tested on scrap
material before cutting the actual
moulding.

CUTTING CROWN MOULDING (FIG. 38, 39)
Crown moulding must be compound mitred with extreme accuracy. The two surfaces on the
crown moulding must fit the wall or ceiling, and each other.
