If it's a welded shaft then it should be easy to fix. Just hove it chucked up in a lathe and have it turned.

It's a shaft with a hub that was slightly bigger welded to it. It's not off by much. Could it be put in a lathe and the face of the hub turned down?

Lathe turning will work only if it's the face that's off. Turning it can not fix off center. Rims center on the lugs.

Kwill, do you have a shipping place nearby that uses metal banding. The place I work just happens to use 1 1/4" steel banding. I asked them to make me a 158" band. Worked great for mockup. I never cut myself on the banding where every time I had the real blade on I left some of my blood on it.

Yeah I could come up with something like that possibly

I didn't do anything with the rim it's a 4.5 on 5 and so is the hub. I'd say when I welded the shaft to the hub I had it off center slightly. So its making the face of the hub have a slight wobble.

The face can be fixed with a lathe.

Turning the hub on a lathe will remove angular wobble but will NOT remove radial run-out (unless new lug bolt holes are drilled). Radial run-out is a big problem for blade life. It is possible that the rim/tire combo also has run-out and that by trying the rim in multiple positions, you might find a spot with minimum run-out.

It's not up and down wobble like if the rim was off center it's like you have a washer on one of the studs between the wheel and the hub.
