Cutting crown molding:

Your miter saw is suited for making the
difficult task of cutting crown molding
easily. To fit properly, crown molding
must be cut with extreme accuracy.
The two surfaces on a piece of crown
molding that fit flat against the ceiling
and wall are at angles that, when
added together equal exactly 90°. Most
crown molding has a top rear angle (the
section that fits flat against the ceiling)
and a bottom rear angle (the section
that fits flat against the wall). The
two common spring angles for crown
molding are: 52°/38° and 45°/45°.
1. Determine the spring angle for the
crown molding, for example, 52/38
degrees as shown in Fig. II.

2. Measure the angle of corner by
angle finder and lock the sliding
fences unit in positions.
3. Place the crown molding piece
upside down with against the table
and the fence as shown in Fig. JJ.
(Think of the table as the ceiling.)
