5. Compound cutting
Compound cutting is the process in which a bevel angle
is made at the same time in which a miter angle is being
cut on a workpiece. Compound cutting can be performed
at the angle shown in the table.

When performing compound cutting, refer to “Press cut-
ting”, “Slide cutting”, “Miter cutting” and “Bevel cut” expla-
nations.
6. 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. (Fig. 36)
There are crown and cove molding joints which are made
to fit “Inside” 90° corners ((1) and (2) in Fig. 37 & 38) and
“Outside” 90° corners ((3) and (4) in Fig. 37 & 38).
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 workpiece 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).

Example:
In the case of cutting 52/38° type crown molding for position (1) in Fig. 37 & 38:
• Tilt and secure bevel angle setting to 33.9° LEFT.
• Adjust and secure miter angle setting to 31.6° RIGHT.
• Lay crown molding with its broad back (hidden) surface down on the turn base with its CEILING CONTACT EDGE
against the guide fence on the saw.
• The finished piece to be used will always be on the LEFT side of the blade after the cut has been made.
