CUTTING BASE MOLDING (Fig. II)
Base moldings and many other moldings can be cut on a
compound miter saw. The setup of the saw depends on
molding characteristics and application, as shown. Perform
practice cuts on scrap material to achieve best results:
1. Always make sure moldings rest firmly against fence and
table. Use hold-down, crown molding vise or C-clamps,
whenever possible, and place tape on the area being
clamped to avoid marks.
2. Reduce splintering by taping the cut area prior to making
the cut. Mark the cut line directly on the tape.
3. Splintering typically happens due to an incorrect blade
application and thinness of the material.

NOTE: Always perform a dry run cut so you can determine
if the operation being attempted is possible before power is
applied to the saw.
The right side sliding fence must be removed when making
any right bevel angle cuts greater than 35 ° in combination
wi_ any right hand miter angle.
This fence must also be removed whenever a 45 ° bevel
angle is desired with a miter angle greater than 22.5 °.
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 flat against
the ceiling and w-all are at angles that, when added
together, equal exactly 90 °.
Most crown molding 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 molding for a 90 ° inside or
outside comer, lay the molding with its broad back surface
flat on the saw table.
When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one changes the other, as well. Also keep in
mind that the angles from crown molding are very easy for
these angles to shift slightly, all settings should be tested
on scrap molding.
Use crown molding vise, whenever possible, and place
tape on the area being clamped to avoid marks. There is
crown molding chart for your reference on page 25.
