When cutting crown molding by this method the bevel angle 
should be set at 33.85°. The miter angle should be set at 
31.6° either right or left, depending on the desired cut for the 
application. See the chart below for correct angle settings 
and correct positioning of crown molding on miter table.
The settings in the chart 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.

CUTTING CROWN MOLDING

Your compound miter saw does an excellent job of cutting 
crown molding. In general, compound miter saws do a better 
job of cutting crown molding than any other tool made.
In order to fit properly, crown molding must be compound 
mitered with extreme accuracy.
The two contact surfaces on a piece of crown molding that 
fit flat against the ceiling and the wall of a room 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°.

LAYING  MOLDING  FLAT  ON  ThE  MITER  
TABLE

See Figure 34.

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.
When setting the bevel and miter angles for compound mi-
ters, remember that the settings are interdependent; chang-
ing one angle changes the other angle as well.
Keep in mind that the angles for crown moldings 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 walls do not have angles of exactly 90°, 
therefore, you will need to fine tune your settings.
