Cutting Aluminum, Cutting Bowed Material

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 MACHINE IS RUNNING.

CUTTING BOWED MATERIAL

1.When cutting flat pieces, 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.

CUTTING CROWN MOULDING

Fig. 35

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 33-7/8 degree left bevel position

	and tighten bevel lock handle.NOTE: A triangle indicator is
	provided on the bevel scale to find this angle quickly.	A
	3. Place the crown moulding on the table with the CEILING	A
	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. 36.	B
	NOTE: The piece of crown moulding used for the outside	B
	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. 36. 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. 36.
