Cutting Crown Moulding - Kobalt SM1815LW User Manual

CUTTING CROWN MOULDING (FIG. 38, 39)
Your compound miter saw is suited for the
difficult task of cutting crown moulding. To fit
properly, crown moulding must be compound-
mitered with extreme accuracy. The two surfaces
on a piece of crown moulding that fit flat against
the ceiling and wall are at angles that, when
added together, equal exactly 90°.
Most crown moulding has a top rear angle (the
section that fits flat against the ceiling) of 52°and
a bottom rear angle (the section that fits flat
against the wall) of 38°.
In order to accurately cut crown moulding for a
90° inside or outside corner, lay the moulding
with its broad back surface flat on the saw table.
When setting the bevel and miter angles for
compound miters, remember the settings are
interdependent; changing one changes the other,
as well.
NOTE: The chart on the next page references
a compound cut for crown moulding ONLY
WHEN THE ANGLE BETWEEN THE WALLS
EQUALS 90°.
