Hi all,
Last year I did some minor restoration work on an old 12" craftsman bandsaw - cleaning up rust, urethane tires, new blade. I fitted it with a 1/2" 4tpi resaw blade, and have used that with no problems until last night.
I was cutting some bowl blanks, and the motor kept stalling. I figured the blade got too dull, as I was also having to push harder in the cut. I switched out the blade for the only other one i had handy, a 1/8" 14tpi blade.
Now, I know that blade is not designed for heavy cuts, but figured i'd get by with it until my replacement resaw blade arrives. But, I'm having a lot of trouble with even light cuts.
- The blade deflects severely when I try to enter the cut - almost 90 degrees sometimes! I've adjusted the guides (which are original - cool blocks are in my to-do list), but it ddn't help.
- in the cut, my blade keeps popping off, usually if I try to back up any. Never had that problem with the bigger blade. The rear bearing stops it popping off the back, but how can I stop it coming off the front? More tension doesn't seem to help, and the blade is otherwise tracking correctly.
Are thinner blades known for being more finicky? I can't wait for my resaw replacement!
Thanks in advance,
Lee
