■ CUTTING CROWN MOLDING
Your compound mitre saw does an excellent job of
cutting crown molding. In general, compound mitre
saws do a better job of cutting crown molding than
any other tool made.
In order to fit properly, crown molding must be
compound mitred with extreme accuracy.
The two contact surfaces on a piece of crown
molding that fit flat against the ceiling and the wall of
a room are at angles that, when added together,
equal exactly 90
0
. Most crown molding has a top rear
angle (the section that fits flat against the ceiling) of
52
0
and a bottom rear angle (the section that fits flat
against the wall) of 38
0
.
■ LAYING MOLDING FLAT
ON THE MITRE TABLE
To use this method for accurately cutting crown
molding for a 90
0
inside or outside corner, lay the
molding with its broad back surface flat on the mitre
table and against the fence.
When setting the bevel and mitre angles for
compound mitres, remember that the settings are
interdependent, changing one angle changes the
other angle as well.
Keep in mind that the angles for crown moldings are
very precise and difficult to set. Since it is very easy
for these angles to shift, all settings should first be
tested on scrap molding. Also most walls do no not
have angles of exactly 90
0
, therefore, you will need
to fine tune your settings.
