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° wall angle
crown moulding.
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 moulding on the table with the
CEILING EDGE of the moulding against the fence,
and make the cut, as shown in Fig. 40.
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. 40. 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.
40.
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°
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. 41. 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. 41.
6. Fig. 42 illustrates the two outside corner pieces; (1)
being the piece cut at (A) Fig. 40 and (2) being the
piece cut at (C) Fig. 41.
7. Fig. 43 illustrates the two inside corner pieces; (1)
being the piece cut at (B) Fig. 40, and (2) being the
piece cut at (D) Fig. 41.
45-45 CROWN MOULDING
NOTE: If you are cutting crown moulding 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°. If you need help
cutting crown moulding for walls set at angles other than
90°, see the instruction sheet “CUTTING CROWN
MOULDING” on the Delta Machinery web site at
www.deltamachinery.com.
