Check out the Yellow Pages for " metal spray". There are a number of
industrial processes that are used to build up worn shafts. The shaft is
usually set up on an old lathe and a powdered metal mixture is trickled into
an oxy/acetylene flame.

Is this the same thing as "spray-welding"? If so, yes, I've seen shafts
fixed with this and they looked great.

cheap & nasty solution Google" LocTite" for a product called "bearing
tight" . Its not perfect but its better than a wobbling shaft

I've used that with success, but it was on a low-load, low-speed
application. Beats using J-B Weld or something, though.
