How to use:  The Finisher

  • How to find Compound Miter Angles for Crown Molding:
    First determine which type of crown molding you're working with, 52/38° (on 52/38° molding the ceiling contact surface is 38° and the wall side is 52°) or 45° (on 45° molding the contact surfaces are both 45°)

  • There are two different charts on this tool, one for each type of crown molding. The chart on the Miter Angle side reads for 45° crown molding and the chart on the Whole Angle side reads for 52/38°.

  • Open the tool and fit into, or around the outside of the surfaces being checked.
  • Read the dial on the Miter Angel side of the tool, using the correct chart for your material, scroll down the left column to find the wall miter angle that you found on the dial, now read across to the right. The center column reads saw bevel (blade/tilt) and the right column reads saw miter.
  • When measuring and marking the crown molding for length, mark the bottom edge that will set against the wall, lay the crown molding flat on the saw. Set your saw to these settings for perfect compound miter cuts.

Example on the 45-degree side of the tool, a 90-degree corner will show 45-degree wall angle in the left column, center column saw bevel is 30 degrees, and saw miter is 35.3 degrees. These angles are the same for an inside or an outside corner; the only difference is the direction of the cut, long point for inside cuts, or short point for outside corners.
