Making Toothed Blades
In the recent Popular Woodworking, there was an article about using toothed blades (see Deneb Puchalski demonstrate them here) and got to thinking how that might be a useful tool, but all ones they were selling were upwards of $60. That's a lot more than I wanted to spend. So I decided to make one. I used a .035" thick 1" diameter cutoff wheel(part # 4550A121 at McMaster-Carr) with a 1/16" arbor. I then shimmed the bed (where the glass is), until it was about 1/32" away from the edge of the wheel. I turned it on and let it rip. I didn't get the teeth in very far, but I think it is enough. I think I could maybe make the teeth more evenly spaced if I used some sort of indexing system.
