Cutting Non-Ferrous Metal; Re-cycle a Trashed Blade!

Postby rwest » Tue Feb 12, 2013 6:05 pm

Hello,

Due to my inattention, I forgot that I didn't need to tilt the blade because I was using the Bias-arm, so I ended up cutting slightly- very slightly into my precision fence before I realized where the weird sound was coming from. It cut the aluminum and also trashed my blade. Since the blade was now worthless for normal use, I figured I would see if it could cut some 1/8" brass bar stock, and it did, so I tried a few other pieces of brass, copper and aluminum, all with the same blade. It got pretty toothless after a while, but it still cut. To set up for cut, use a very minimal pitch, raise the blade height just a few degrees each pass and if the blade starts getting toothless, just take passes along the section of blade between the gaps.
