CUTTING BOWED MATERIAL
Check to see if your workpiece is bowed. If it is, make sure the
material is positioned on the table as shown in Fig. 34.
If the material is positioned the wrong way, as shown in Fig. 35, the
workpiece will pinch the blade near the completion of the cut.
WORK SUPPORT EXTENSIONS
For support when cutting long pieces, a work support extension can
be constructed. Fig. 36 illustrates the miter saw mounted to two
standard 2 x 4’s (A). Fasten the four mounting legs (two of which are
shown at (B) Fig. 36 to the 2 x 4’s, using four screws (not supplied)
through the four holes in the mounting legs. The length of the 2 x 4’s
(A) can vary, depending on the kind of work that will need to be cut.
NOTE: Ensure that the top of the support 2 x 4’s (C) are level
with the miter saw table.
This is critical because the distance from the top of the
2 x 4’s (A) to the miter saw table varies from saw to saw. In most
cases, standard 2 x 4’s (C) can used. If these are too high, cut the 2
x 4s (C) to provide this height or use other properly-sized wood.
CUTTING CROWN MOLDING
One of the many features of the saw is the ease of cutting crown
molding. The following is an example of cutting both inside and
outside corners on 52°/38° wall angle crown molding.
1. Move the table to the 31.62° 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 33.86° 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 molding on the table with the CEILING EDGE of
the molding against the fence, and make the cut, as shown in
Fig. 37.
NOTE: The piece of crown molding used for the outside corner
will always be on the right hand side of the blade, as shown at
(A) Fig. 37. The piece of crown molding used for the inside
corner will always be on the left hand side of the blade, as shown
at (B) Fig. 37.
4. To make the matching halves of the inside and outside corners,
rotate the table to the 31.62° left miter position.
NOTE: A positive stop is provided to find this angle quickly. The
saw blade is already tilted to the 33.86° left bevel position from
the previous cut.
5. Place the crown molding on the table with the WALL EDGE of
the crown molding against the fence and make the cut. Again, the
piece of crown molding used for the outside corner will always be
on the right side of the blade, as shown at (C) Fig. 38. The piece
of crown molding used for the inside corner will always be on the
left side of the blade, as shown at (D) Fig. 38.
6. Fig. 39 illustrates the two outside corner pieces; (A) being the
piece cut at (A) Fig. 37 and (C) being the piece cut at (C) Fig. 38.
7. Fig. 40 illustrates the two inside corner pieces; (B) being the
piece cut at (B) Fig. 37, and (D) being the piece cut at (D) Fig. 38.
45-45 CROWN MOLDING
NOTE: If you are cutting crown molding that is 45°-45°, follow the
same procedure above, with the exception that the bevel position will
always be at 30° and the miter position will be 35-1/4° to the right or
left.
OTHER ANGLES
NOTE: The above instructions are assuming the angle between the
walls is 90°.
