Topic tags/keywords: band saw blade slip

I have an old Craftsman bandsaw that my dad passed on to me when he upgraded to a better one. It is not a super high quality tool – aluminum table, plastic covers, etc. I had tuned it up and got it running fairly well, however. Now I’m having trouble with the blade slipping on the wheel. The motor is still running and the lower wheel is spinning – but the blade stops with very little resistance. I already checked the tension—I have tried to tighten it as much as a could (ultimately a bit beyond the “1/2 inch” setting). I think that the upper portion is even bending a little bit.

Is there anything else that I should be checking here?

There should be a key that fits in a slot in the shaft and in the lower wheel. It’s either there or in the drive pully. A set key might be loose or something simple like that.

I’ll try to take a look. As far as can tell so far, though, I think that the lower wheel is still turning, just not taking the blade with it.

Are the tires hardened on your wheels? If they get hard and slippery, that could cause your blade to slip.

You might try cleaning off the tires with something like Simple Green. Also, is the blade tracking consistently and in the middle of the wheel?

Thanks for the input. I tried to clean up the tire and that helped a bit. At least it will get me through my current project. This may be a good excuse to upgrade my bandsaw.

Or just an excuse to change the tires on your current band saw…
