I heard of something once that worked like form-a-thread I believe.
You put a paste on a worn area of a shaft and when it cured you could
machine it back to the original diameter.
We have a shaft in an old horizontal mill. One end is worn about .030
and fits into a bearing. They have been running this machine slotting
screws for years but I want it fixed. This seeems like the easiest way
if it works.

I'd think you'd be a lot happier if you took
out the shaft, turned down the worn area and
sleeved it. There's an article in one of the
recent home shop machinist magazines detailing
how to fix worn shafts. I could look it up
but I don't have it handy here at work.
