[TheForge] Vice repair

[Peter Fels And Phoebe Palmer]

Hi Bob;
I was wrestling with my old lathe trying to get it to cut a 
replacement female thread for a stripped 6" Colombian vise i was 
given....my wife said, " Why don't you buy one". I said that 
they'd been out of business for 40 years probably....but she 
meant the thread.
Couldnt find an economical acme thread that was as fast, but 
bought a slower one and a 3" coupling nut to match. Some 
cutting,welding and grinding later it seems to work just fine...PF
