CUTTING
CROWN MOLDING
Your compound miter saw is excellent for cutting crown molding.
In order for it to fit propedy, 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 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 °.
Laying Molding
Flat on the Miter Table (See Figure 28)
To use this method for accurately cutting 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.
Remember that when you set the bevel and miter angles for compound miters,
the settings are interdependent. When you change one angle, the other angle
is changed as well.
Keep in mind that the angles for crown molding are very precise and difficult to
set. Since it is very easy for these angles to shift, all settings should first be
tested on scrap molding. Also, most wails 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+85°. The miter angle should be set at 31.62 either left or right, depending
upon
the desired cut for the application.
See the following Cutting Crown Molding 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 ° angles. The crown molding is placed flat on
the miter table, using the compound
features of your miter saw.
