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 angle shown in the
table.

When performing compound cutting, refer to "Press
cutting", "Slide cutting", "Miter cutting" and "Bevel
cut" explanations.
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.

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 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. A:
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.
