CUTTING CROWN MOLDING
Your miter saw is better suited to the task of cutting crown molding than any tool made. In order to fit prop- erly, crown molding must be compound mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding are at angles that, when added together, equal exactly 90°. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom rear angle (the part that fits flat against the wall) of 38°.
Your miter saw has special
The chart below gives the proper settings for cutting crown molding. (The numbers for the miter and bevel settings are very precise and are not easy to accurately set on your saw.) Since most rooms do not have angles of precisely 90°, you will have to fine tune your settings anyway.

MOLDING LAYING FLAT AND USING THE COMPOUND FEATURES
1.Move the left side fence out of the path of the blade before attempting any of the following cuts.
2.Molding laying with broad back surface down flat on saw table (Fig. 29).
3.The settings below are for all Standard (U.S.) crown molding with 52° and 38° angles.

When setting bevel and miter angles for all compound miters, remember that:
The angles presented for crown moldings are very precise and difficult to set exactly. Since they can easily shift slightly and very few rooms have exactly square corners, all settings should be tested on scrap molding.

ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING
Place the molding on the table at an angle between the fence and the saw table, as shown in Figure 30. Use of the crown molding fence accessory (DW7084) is highly recommended because of its degree of accuracy and convenience. The crown molding fence accessory is available at extra cost from your local dealer.
The advantage to cutting crown molding using this method is that no bevel cut is required. Minute changes in the miter angle can be made without affecting the bevel angle. This way, when corners other than 90° are encountered, the saw can be quickly and easily adjusted for them. Use the crown molding fence accessory (DW7084) to maintain the angle at which the molding will be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING ANGLED BETWEEN THE FENCE AND BASE OF THE SAW FOR ALL CUTS:
1.Angle the molding so the bottom of the molding (part which goes against the wall when installed) is against the fence and the top of the molding is resting on the base of the saw, as shown in Figure 30.
2.The angled “flats” on the back of the molding must rest squarely on the fence and base of the saw.
