When cutting crown molding by this method the bevel
angle should be set at 33.85°. The miter angle should
be set at 31.62° either right or left, depending on the
desired cut for the application. See the chart below for
correct angle settings and correct positioning of crown
molding on miter table.
The settings in the chart below can be used for cutting
All Standard (U.S.) crown molding with 52° and 38°
angles. The crown molding is placed flat on the miter
table using the compound features of your miter saw.
OPERATION
If the warped material is positioned the wrong way as
shown in figure 41, it will pinch the blade near the
completion of the cut.
