CUTTING CROWN MOLDING (Fig. 38)
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 °
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. When setting the bevel and miter angles for compound miter cuts,
remember that the settings are interdependent; changing one changes the other.
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 using this method, the bevel angle should be set
at 33.9 o.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 ospring angles. The crown molding is placed flat on the
miter table, using the compound features of your miter saw.
Always use the hold-down clamp, and place tape on the area being clamped to
avoid marks on the workpiece.
