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
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.
(Fig. 35 - 37)
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.

made.
7. Wood facing
Use of wood facing helps to assure splinter-free cuts
in workpieces. Attach a wood facing to the guide fence
using the holes in the guide fence.
See the figure concerning the dimensions for a
suggested wood facing. (Fig. 38)
CAUTION:
• Use the straight wood of even thickness as the wood
facing.
WARNING:
• Use screws to attach the wood facing to the guide
fence. The screws should be installed so that the
screw heads are below the surface of the wood
