I've got a shaky Delta bandsaw with a wobbly drive pulley. The local service center had a replacement pulley, but it's only slightly better than the first one.
When I spin the wheel by hand, I can actually see the pulley wobble. A link belt helped a bit, but it's still quite shaky. I can only assume the wobbly drive pulley is part of the problem since it doesn't shake much when I remove the belt and run the motor by itself.
So, I've been looking into machined pulleys.
First, I don't really know what to measure to ensure I get the right pulleys. Second, I have no idea where to pick one up. So I've spent a lot of time on google, but haven't become any less confused.
If I measured the pulleys correctly (which I don't think I have), the drive pulley has a keyed 3/4" bore and a 4-5/8" OD and the motor pulley (which seems to be okay) has a keyed 21/32" (maybe 5/8") bore and a 2-13/64" (maybe 2 1/4") OD.
Any help ya'll can offer is greatly appreciated!
