Helpful Hints When Cutting Compound Miters
Tips for Cutting Compound Miters on Picture Frames and
Boxes (Model 113.235221 Only)
A compound miter is a cut requiring both a miter setting and
bevel setting. A compound miter is used for making frames or
boxes that have sloping sides and are wide at one end and
narrow at the opposite end. Compound miters are "tricky" to
make because the miter setting and bevel setting are directly
related to each other. Every time the miter setting is changed
the bevel setting must also be adjusted; likewise every adjust-
ment to bevel requires a corresponding adjustment to miter.
Because it may take several tries to obtain the desired angle
it as advisable to make test cuts in a scrap piece of material.
Tips for Cutting Moldings
A compound miter saw is also excellent for cutting molding.
Molding is sometimes difficult because in order to fit correctly
it must be precisely cut.
Cutting Base Moldings
Base moldings and many other moldings can be cut on a
miter saw. The set up of the saw depends on your molding
and your application as shown. Always make sure moldings
rest firmly against fence and table.
Cutting Crown Moldings
Plan Ahead so that you are not tempted to reach across saw
blade to steady newly severed workpiece.
Crown Moldings can be cut using two methods, workpiece
standing up (as it would be mounted on wall) and workpiece
lying flat on table (see chart and illustration).
Most Standard (U.S.) crown molding has a top rear angle
(angle that fits next to ceiling) of 52 ° and a bottom rear angle
(angle that fits against wall) of 38 °.
1. Workpiece standing up, usually cut inverted from ceiling
mounted orientation. Fixturing: Optional fence mounted
crown molding jigs which locate workpiece. See recom-
mended accessories. (Table clamp is helpful). Hand is
holding workpiece to fence when the cuts are made. All
cuts are made at 0° bevel setting and 45° miter (see illus-
tration).
2. Workpiece lying flat for compound cut (see chart and
illustration).

NOTE: On all above cuts lay molding with broad back surface
flat on table.
Pretesting Compound Settings On Scrap Material Is
Extremely Important!
NOTE: Above angles assume that the constructed wall corner
is exactly 90 _. In typical construction, this is not always the
case. Measure wall and make necessary adjustments to
angles.
