5. Cutting crown and cove moldings
Crown and cove moldings can be cut on a compound
miter saw with the moldings laid flat on the turn base.
There are two common types of crown moldings and one
type of cove moldings; 52/38° wall angle crown molding,
45° wall angle crown molding and 45° wall angle cove
molding. See illustrations.
There are crown and cove molding joints which are
made to fit “Inside” 90° corners ((1) and (2) in Fig. A) and
“Outside” 90° corners ((3) and (4) in Fig. A).
Measuring
Measure the wall length and adjust workpiece on table to
cut wall contact edge to desired length. Always make
sure that cut workpiece length at the back of the work-
piece is the same as wall length. Adjust cut length for
angle of cut. Always use several pieces for test cuts to
check the saw angles.
When cutting crown and cove moldings, set the bevel
angle and miter angle as indicated in the table (A) and
position the moldings on the top surface of the saw base
as indicated in the table (B).
