I don't cut metal with a saw blade, on purpose anyway. But years ago I bought a blade for my circular saw at Big Lots, for $10. Carbide tipped, zipped thru wood like a hot knife thru butter, still does for that matter. I think the blade would be good thru aluminum, don't know if it would scratch it or not, but a run with a sander would solve that. Thing is, if it was only good for a few pieces, then had to be replaced, it was cheap. Haven't been in Big Lots for a number of years, but they always had things at a low price. Bought a batch of metal quick clamps for $1 each, should have bought them all. If you have one near you wouldn't hurt to check it out. I think I'll try to remember to check the one here, if I remember next time I'm in the county seat.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
