See Figure 38.
To use this method for accurately cutting crown molding
for a 90 inside or outside corner, lay the molding with its
broad back surface flat on the miter table and against the
fence.
When setting the bevel and miter angles for compound
miters, 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 not have angles of exactly
90, therefore, you wil! need to fine tune your settings.
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 on page 30 can be used for cut=
ting A!! 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 the miter saw.
