CUTTINGCROWNMOLDING(FIG. AA,BB)
NOTE: The chart below references s compound cut for crown motding ONLY WHEN THE ANGLE BETWEEN THE WALLS EQUALS EXACTLY 90 °.
Your compound miter saw is suited for the difficult task of cutting crown molding. To fit properly, crown molding must be compound=mitered with extreme accuracy.

fiat against the ceiling and wall are at angles that, when added together equal exactly 90°.
Most crown molding has a top rear angle (the section that fits fiat against the ceiling) of 52°and a bottom rear angle (the section that fits fiat against the wall) of 38°.
tn order to accurately cut crown molding for s 90° inside or outside corner, lay the molding with its broad back surface fiat on the saw table.
When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one changes the other, as well Also keep in mind that the angles from crown molding are very easy for these angles to shift slightly, al! settings should be tested on scrap molding.
