I actually still have a 50's vintage Rockwell drill press with a two speed gearbox. Haven't used it in years but in looking at getting a VFD so I can run it with the 5hp 3 phase motor.
wait what?
a 5hp 3ph? Carrumba.
Edit: I had a 5hp 3-phase 10" table saw for many years; it was unstallable. I worked that saw for hours and hours all week long, ramming 1"oak boards thru it. Built me some nice arms on the saw, yessir.
