Fig. 31

CUTTING CROWN MOLDING

Crown molding must be compound mitered with
extreme accuracy. The two surfaces on the
crown molding must fit the wall or ceiling, and
each other. The two cut surfaces of the mitered
molding must add to a 90° angle. Most crown
molding 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.
OPERATING THE MITER SAW
Crown molding is thin and splinters very easily.
Crown molding with widths less than 4½" should
be with the edges resting on both the fence and
the base. Crown moldings with widths between
4½" and 10 " should be cut with the back of the
molding lying flat on the base.
NOTE: Refer to the chart below that explains
the correct angles for cutting the various
elements of the crown molding corners.
