I have a grizzly G0709 gunsmith lathe. Unfortunately, it has one of those cheapo "growling" motors. Here's what it sounds like from a video posted on YouTube (not mine): https://www.youtube.com/watch?x-yt-...yt-cl=85114404&feature=player_detailpage#t=35.
I'm considering replacing this motor with a three-phase motor and VFD. I added a VFD to my Bridgeport clone a couple years ago and it worked great. With the lathe however, I see lots of contactors and other wiring that complicates the install.
At a minimum, I'd like to use the apron lever for forward, stop and reverse, and the foot pedal for emergency stops. I assume the proper approach is to tear out all the contactors and start over with the wiring? Perhaps reusing the spindle switch (from the apron lever) and emergency stop switch from the foot pedal?
