This thread is alive! So I'll add one more. Got my hands on an old broke down bench grinder. 3/4 horse with 8" wheels looked promising. Yeah. I could use that. What killed it was a bearing seized and dug a groove in the armature shaft. The fix is to turn the shaft down and press a sleeve on thereby restoring the shaft to it's original dimension. But an armature is foot long sort of thing that needs support out there somewhere down the lathe bed and what's needed for that is a steady rest ... which my lathe didn't have. So I made my own. Had my usual love/hate relationship with welding on that one. I love it when I make a pretty weld, but when it comes up ugly I hate that particular discipline with a bloody passion!
