CUTTING ALUMINUM

Aluminum extrusions (aluminum screens and storm

windows) can easily be cut with your miter saw. When

cutting aluminum extrusions, 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. 32.

The wrong way to cut aluminum angles is illustrated in

Fig. 33. 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 BLADE IS RUNNING.

CUTTING BOWED MATERIAL

1. First check to see if the material is bowed. If it is,

make sure the material is positioned on the table as

shown in Fig. 34.

2. 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, construct a work

support extension. Fig. 36 illustrates the miter saw

mounted on 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 workpiece.

NOTE: MAKE SURE 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 them to fit. If the 2 x 4’s are too low, use 2

x 6’s. If these are high, cut them to the correct height.

fence (A) and (B) Fig. 31. This auxiliary fence is

constructed of straight wood approximately 1/2” thick by

3” high by 16 inches long as shown at (B); and 1/2” thick

by 5” high by 17” long (A) Fig. 31.

NOTE: The auxiliary fence (A) is used only with the saw

blade in the 0° bevel position (90°) to the table. The

auxiliary fence must be removed for all bevel cuts (blade

tilted).
