This weekend I purchased a Freud non-ferrous metal blade.
Putting my fears a side I grabbed the WD-40 and some clamps. After clamping the 1/2 x 3 aluminum bar to the chop saw, I started cutting.
The finished cut was fantastic; I just went slow and made sure the WD-40 was being used to lube the blade. After the bar I trimmed up some 1530 series 80/20 with the same results, I should have purchased one of these when I first started this project!
