5 hp 3 phase motor to a 3/4 hp single phase..?
In article , Gunner says...
One drill bit, one tap, fast reverse. Worked like a champ and I was
only a couple hours doing it all. Doing that by hand...and Id still
be at it G
Alternative approach, Procunier tapping head. Backs out at twice
the speed it goes in. Nice.
I myself plug reverse and brake my converter-driven machines
all the time.
