CUTTING BASE MOLDING (FIG. FF) 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.

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 corner, 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.

CUTTING CROWN MOLDING (FIG. GG, HH)

!WARNING

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 wall are at
