CU'I'I'ING CROWN MOLDING
The compound miter sew does an excellentJobof cut-
ting crown molding. In general, compound miter eaws do
a better Jobof cuffing crown molding than any othertool
made,
In order to fit properly,crown molding must be compound
mltaredwith extreme accuracy,
The two contact surfaces on a piece of crown molding
that fit flat against the ceiling and the wall of a roomare at
anglesthat, when added together,squat exactly g0".Most
crown molding has a top rearangle (_e section _at fits
fiat againstthe ceiling}of 52"and a bottom rear angle(the
sectionthat fits fiat against the wail}of 38",

When settingthe bevel and miter angles for compound
miters, rememberthat the settingsare interdependent;
changing one angle changes the other angleas well.
Keep in mind that the angles for crown moldingsare very
preciseand dl_cult to set. Since it is very easy for these
angles to shift,all settingsshouldfirst be tested on scrap
molding. Alsomost wafts do not have angles of exactly
90", _erefore, you wlfl need to fine tune yoursettings.
When cutting crown molding by this method the bevel
angle shouJd be set at 33.9" either rightor left. The crown
molding stops are marke_ either33.9"or 45"for the exact
angle for cuffing crown molding (see _gure 40).The miter
angle shouldbe set at 31.62" either right or left, depending
on the desirecicut for the applieation. See the chart below
for correctangle settingsand correctpositioningof crown
moldingon miter table.
The settingsin the chart on pegs 39 can be used for cut-
tingAJ]Standard (U.S.) crown molding with 52"and 38"
angles. The crown molding is placed flat on _.hemiter table
using the compound features of your miter saw.
