er32 spindle thread worn out anything i can do?

[komatias]

A week or so ago I took my motor in to a rewinder to have it serviced. They said that the shaft front needed some material sprayed on and the whole thing finished. Did not cost too much either.

In your case, you may be able to build up some weld on it and get it finishe machined and ground, inside. Can give you contacts of the guys I used if you want.

I would suggest sending a PM to John S (John Stevenson), a member of this forum. He repairs motor shafts and spindles of various sorts professionally. From what I have read on various forums, you cannot find a more capable person than him to deal with your problem.
