CUTTING CROWN MOLDING
Your compound mitre saw does an excellent job of cutting
crown molding. In general, compound mitre saws do a better
job of cutting crown molding than any other tool made.
In order to fit properly, crown molding must be compound
mitred 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 MITRE
TABLE
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 mitre table and against the fence.
When setting the bevel and mitre angles for compound
mitres, remember that the settings are interdependent,
changing 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 a scrap
molding. Also most walls do not have angles of exactly 90°,
therefore, you will need to finetune your settings.
