CUT'rING CROWN MOLDING
Your compound mRer saw does an excellent Jobof cutting
crown molding. In general, compound miter saws do a
better job of cutting crownmolding than any other tool
made.
In order to fit properly,crown molding must be compound
mitered with extreme accuracy.
The two contact surfaces on a piece of crown molding
that fit flat against the ceilingand the wall of a room are at
angles that, when added together, equal exactly go'. Most
crown molding has a top rear angle (the section that fits
fiat against the cs[Ting) o f 52"and a bottom rear angle (the
section that fits fiat against the wall) of 38".
LAYING MOLDING FLAT ON THE
MITER TABLE
See Figure 31.

broad back surface flat on the miter table and against the
fence.
52" CEILING
When setting the bevel and miter angles for compound
miters, rememberthat the settingsare interdependent;
changing one angle changes the other angle as well.
Keep in mind that the angles for crownmoldings are very
precLseand diffLcuit t o sat. Since it tsvery easy for these
angles to shift, all settings should first be tested on scrap
molding.Also most wells do not have angles of exactly
90", therefore, you witl need to fine tune yoursettings,
When cutting crown molding by this method the bevel
angle should be set at 33.85".The miter angle shouldbe
set at 31.62" either dght or left, dependingon the desired
cut for the application. See the chart below for correct
angle settings and correct positioningof crownmolding
on miter _ble.
The settings in the chart below can be used for cutting All
Standard (U.S.) crownmolding with 52"and 38"angles.
