CUTTING BOWED MATERIAL
When cutting flat pieces, first check to see if the mate-
rial is bowed. If it is, make sure the material is posi-
tioned on the table as shown in Fig. 40.
If the material is positioned the wrong way, as shown in
Fig. 41, the workpiece will pinch the blade near the
completion of the cut.

CUTTING ALUMINUM
Aluminum extrusions such as used for making aluminum
screens and storm windows can easily be cut with your
compound miter box. When cutting aluminum extru-
sions, or other sections that can be cut with a saw blade
and are within the capacity of the machine, position the
material so the blade is cutting through the smallest
cross-section, as shown in Fig. 38. The wrong way to cut
aluminum angles is illustrated in Fig. 39. Be sure to apply
a stick wax (similar to Johnson’s stick wax #140) to the
blade before cutting any aluminum stock. This stick wax
is available at most industrial mill supply houses. The
stick wax provides proper lubrication and keeps chips
from adhering to the blade.
NEVER APPLY LUBRICANT
TO THE BLADE WHILE THE MACHINE IS RUNNING.
