When cutting crown molding by this method the bevel angle
should be set at 33.85°. The mitre 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 mitre table.

The settings in the chart below can be used for cutting all 
standard crown moulding with 52° and 38° angles. The crown
moulding is placed flat on the mitre table using the compound
features of your mitre saw.

CUTTING WARPED MATERIAL

(See Figures 26 & 27)

When cutting warped material, always make sure it is
positioned on the mitre table with the convex side against the
fence as shown in figure 26.

If the warped material is positioned the wrong way as shown
in figure 27, it will pinch the blade near the completion of the
cut.
