Cutting Crown Moulding; Bevel/Miter Settings - Craftsman MULTI-MITER 137.242760 Operator's Manual

CUTTING CROWN MOULDING (Fig. GG, HH)
Your compound miter saw is suited for the difficult task of
cutting crown molding. To fit properly,crown molding must
be compound-mitered with extreme accuracy. The two
surfaces on a piece of crown molding that fit fiat against
the ceiling and wall are at angles that, when added
together, equal exactly 90".
Most crown moldings have a top rear angle (the section
that fits flat against the ceiling) of 52° and a bottom rear
angle (the section that fits fiat against the wall) of 38 °.
In order to accurately cut crown molding for a 90 ° inside or
outside corner, lay the molding with its broad back surface
fiat on the saw table.
When setting the bevel and miter angles for compound
miters, keep in mind that the angles for crown molding are
very precise and difficultto set exactly. Since it is very
easy for these angles to shift slightly,all settings should be
tested on scrap molding.
