Cutting Crown Moldings
Your compound miter saw does an excel-
lent job of cutting crown molding. How-
ever, in order to fit properly, crown
molding must be cut with extreme accu-
racy.
Two Methods of Cutting Crown Molding
Crown molding may either be cut (1) flat
on the miter saw table or (2) angled to the
table and fence. (See square below) Most
standard (U.S.) crown molding has a top
rear angle (angle that fits next to the ceil-
ing) of 52° and a bottom rear angle (angle
that fits against wall) of 38°. Your miter
saw has special miter settings at 31.6° left
and right and a bevel setting at 33.9° to
use when cutting crown molding flat on
the miter saw table. These settings are
identified with a “CM” mark.
Remember: Even though all of these
angles are standard, rooms are very
rarely constructed so the corners are
exactly 90°. You will need to “fine tune”
these settings and make necessary
adjustments to the cutting angles.
Cutting Crown Molding Flat on the
Miter Saw Table
The advantage of cutting crown molding
flat on the table is that it is easier to
secure the molding at the correct cutting
position. Also larger pieces of crown
molding may be cut laying flat on the miter
saw table.
1. Set the bevel and miter angles using
the chart below. Tighten the miter lock
knob and the bevel lock knob.
2. Once again using the chart below cor-
rectly positions the molding.
3. Lower the head assembly, activate the
switch and make the cut. Wait until the
blade comes to a complete stop before
allowing the head assembly to return to
the “UP” position and/or removing the
workpiece.
4. ALWAYS PRETEST COMPOUND
SETTINGS ON SCRAP MATERIAL TO
CONFIRM CORRECT ANGLES.
