When I picked up my battery "baskets" from my local weld shop, I mentioned how difficult it is to cut 1/2 inch thick 6061 aluminum plate.
My guy told me to wax up the sides of my table saw blade and run it through
Well, we decided that we needed to trim our motor plate so we set the fence on the table saw, waxed the blade a little and ran the plate through like a piece of plywood!
It went as smooth as butter. No blade change. Same old blade that has been on my saw for years.
There's a tip for you guys
