OPERATION

When cutting crown molding by this method the bevel angle should be set at 33.85°. The miter angle should be set at 31.62° either right or left, depending on the desired cut for the application. See the chart below for correct angle settings and correct positioning of crown molding on miter table.

The settings in the chart below can be used for cutting All Standard (U.S.) crown molding with 52° and 38° angles. The crown molding is placed flat on the miter table using the compound features of your miter saw.

CUTTING WARPED MATERIAL

See Figures 40 and 41.

When cutting warped material, always make sure it is positioned on the miter table with the convex side against the fence as shown in figure 40.

RIGHT

If the warped material is positioned the wrong way as shown in figure 41, it will pinch the blade near the completion of the cut.
