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.

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.
