CUTTING CROWN MOLDING
Your compoundmiter saw does an excellent job of cutting crown molding. In general, compound miter saws do a better job of cuffing crown moldingthan any other tool made.
In order to fit properly,crown molding must be com- pound m/tared with extreme accuracy.
The two contact surfaces on a piece of crown molding that fit fiat against the ceiling and the wall of a room are at angles that, when added together, equal exactly 90 °. Mcet crown molding has a top rear angle (the sectionthat fits fiat against the ceiling) of 52° and
abottom rear angle (the section that fits fiat against the wall) of 38 °.

To use this method for accurateiy cuttingcrown moldingfor a 90 ° inside or outside comer, lay the moldingwith its broad beck surfacefiat on the miter table and against the fence.
When settingthe beval and miter angles for com- pound miters, remember that the settingsare interde-
pendent; changing one angle changes the other angle as well.
Keep in mind that the angles for crownmoldingsare very precise and difficultto set. Since it is very easy for these angles to shift,all settingsshouldfirst be tested on scrap molding.Also mostwalls do not have angles of exactly 90", therefore, you will need to fine tune your settings.
