Aligning the drive shafts motor to band saw

Hello, the drive from the motor doesn't align with the drive to the band saw, off by more than an 8th of an inch.
I'm afraid that it will put undue stress on the coupler and snap it. Is there a video on how to bring them into alignment?
thank you

This is usually a simple alignment but varies a bit with your actual equipment. Your bandsaw mounting tubes will either be straight, have a small offset (1/4", I think) that allows horizontal adjustment, or a large offset. If you can say which you have it will be easier to help you. The alignment procedure is different for each. You can provide a picture if you're not sure.

The band saw itself must be on a solid base and the motor should have a clutch. Both drive shafts need to be aligned in the same plane with each other and at the same height relative to the motor output and band saw input shaft. This ensures that no stress is placed upon either shaft due to misalignment, which would cause premature wear or breakage.

jroge11,
Welcome to the Shopsmith Forum. I believe you are talking about mounting the Bandsaw on a Shopsmith Mark tool and not mounting it on a separate stand. If so, it should align to the upper aux. shaft of the Headstock without difficulty unless the Mark base/stand itself is not assembled/aligned correctly putting the Headstock off. That is difficult to imagine happening. There have been three types of mounting posts for the Bandsaw. The first were straight posts with collars and are the most difficult to align. They are not that hard to align though. Some lateral give is there by "rocking" the Bandsaw front to back to align the hubs. Once the height and lateral adjustment is done lock the collars against the top of the mounting holes for future mounting. The other two types of Mounting Posts for the Bandsaw are the eccentric and special eccentric posts. With them it is easier to align the hubs as the eccentric can turn to align it laterally and the offset sits on the top of the mounting holes.
My 1956 restored Bandsaw has straight posts and aligns perfectly to my Mark 7 Headstock.
