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.

Cutting Crown Molding

Your miter saw is well suited to the task of cutting crown molding. In order to fit properly, 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 90º. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52º and a bottom rear angle (the part that fits flat against the wall) of 38º.

Your miter saw has special pre-set miter latch points at 31.62º left and right for cutting crown molding at the proper angle and bevel stop pawls at 33.9º left and right. There is also a mark on the bevel scale at 33.9º.

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 90º, you will have to fine tune your settings anyway.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

INSTRUCTIONS FOR CUTTING CROWN MOLDING LAYING FLAT AND USING THE COMPOUND FEATURES

1.Molding should lay flat with broad back surface down on saw table (Fig. 17).

2.Top of molding against fence.

3.The settings below are for all standard (U.S.) crown molding with 52° and 38° angles.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

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 18. Use of the crown molding fence accessory (DW7084) is highly recommended because of its degree of accuracy and convenience (Fig. 1). The crown molding fence accessory is available for purchase 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 90º are encountered, the saw can be quickly and easily adjusted for them. Use the crown molding fence accessory 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 saw table, as shown in Figure 18.

2.The angled “flats” on the back of the molding must rest squarely on the fence and saw table.
