CUTTING CROWN MOULDING

One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and outside corners on 52/38 degree wall angle crown moulding.

NOTE: The following procedure for inside or outside crown molding corners is the same with the exception that the bevel position will always be at 30 degrees and the miter position will be 35-1/4 degrees to the right or left.

1.Move the table to the 31-5/8th degree right miter position and lock the table in position.

NOTE: A positive stop is provided to find this angle quickly.

2.Tilt the saw blade to the 33-7/833-7/8 degree left

bevel

position and tighten bevel lock handle.

NOTE: A triangle indicator is provided on the bevel scale to find this angle quickly.

3.Place the crown moulding on the table with the CEILING EDGE of the moulding against the fence, and make the cut, as shown in Fig. 42.

NOTE: The piece of crown moulding used for the outside corner will always be on the right hand side of the blade, as shown at (A) Fig. 42. The piece of crown moulding used for the inside corner will always be on the left hand side of the blade, as shown at (B) Fig. 42. Note that the accessory work clamp (E) is being used to hold the workpiece in position.

4.To make the matching halves of the inside and outside corners, simply rotate the table to the 31-5/8

degree left miter position.

NOTE: A positive stop is provided to find this angle quickly. The saw blade is already tilted to the 33-7/8 degree bevel position from the previous cut.

5.Place the crown moulding on the table with the WALL EDGE of the crown moulding against the fence and make the cut. Again, the piece of crown moulding used for the outside corner will always be on the right side of the blade, as shown at (C) Fig. 43. The piece of crown moulding used for the inside corner will always be on the left side of the blade, as shown at (D) Fig. 43. Again, the accessory work clamp (E) is being used to hold the workpiece in position.

6.Fig. 44 illustrates the two outside corner pieces; (1) being the piece cut at (D) Fig. 43 and (2) being the piece cut at (C) Fig. 43.

7.Fig. 45 illustrates the two inside corner pieces; (1) being the piece cut at (B) Fig. 42, and (2) being the piece cut at (A) Fig. 42.
