CUTTING CROWN MOLDING (Fig. 18)
Your miter saw is ideal for cutting
crown molding. In order to fit
properly, crown molding must be
compound-mitered with extreme
accuracy. To fit flat against the
ceiling and wall, the sum of the
angles of the crown molding’s two
connecting surfaces must equal
90°(Fig.18)
Most crown molding has a high top
rear spring angle (the section that
fits flat against the ceiling) of 52°
and a bottom rear spring 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
miter table and against the fence
(Fig.18).
When setting the bevel and miter
angles for compound miter cuts,
remember that the settings are
interdependent; changing one changes the other, as well.
Keep in mind that since it is very easy for the angles of crown molding to shift
slightly, all settings should be tested on scrap molding. Also, most walls do
not have angles of precisely 90°, therefore, you will need to fine tune your
settings.
When cutting crown molding, the bevel angle should be set at 33.9°, the miter
angle should be set at 31.6° either left or right, depending upon the desired
cut for the application. See the following table for correct angle setting and
correct positioning of the crown molding on the miter table.
The settings in the table below can be used for cutting all standard (U.S.)
crown molding with 52 °And 38 ° spring angles. The crown molding is placed
flat on the miter table, using the compound features of your miter saw.
Always uses the hold down clamp, and place tape on the area being clamped
to avoid marks on the workpiece.
