Ian,I have been looking at them today and they seem more simple than I expected.ThanksHank

I just hooked up my VFD this afternoon.  I worked almost exactly like you described, but rather than changing the voltage, the dial on the front changes the frequency of the wave form being generated.  I didn't change any of the defaults, it just worked out of the box.
Perhaps somebody could help you set this up, get the defaults changed to suit you, then no further changes/programming needed.
Good luck!
Cheers,  Ian.

Ian,Thank you,Yes I have just started looking at them, and they seem like the way to go.  I am just nervous about anything I have to program.  I am not good with electronics, I even have to farm out changing the time on my clock in my truck ;-)  I need a controller that has two wires going in and three coming out with a big dial on the front that reads the voltage I want and nothing else lolHank

have you consider using a VFD?  They are fairly cheap and I give many more benefits (such as speed control, ramp up/down control, braking, etc.).
I'm going with a 2HP Automation Direct GS2:https://www.automationdirect.com/adc/Shopping/Catalog/Drives/GS2_(115_-z-_230_-z-_460_-z-_575_VAC_V-z-Hz_Control)
Lovely lathe!
Cheers!  Ian.

Thanks Kieth,I thought the power less was only if you did not have capacitors and just relied on the third phase from the idler motor.I will check the surplus centrethanks againHank

Hank,
I have a rotory converter on my boat. Keep in mind you will only get about 2/3 of the input power on the output as some losses are acrewed to spin the converter. Also 208 volt motors will run on 220 just a bit faster than on 208.
There are solidstate converters out there, no rotating parts and more power . Check

Hi All,I need some input on converting single phase power to 3 phase.  I am thinking about going with a rotary phase converter for the two small motors on the lathe.  I am not sure though if my 208 V motors can handle 220-240 volt power.  I need to check my power source but it will be at least 220 I am guessing.  Maybe I need to use an inverter with variable output power if that exists?Hank _______________________________________________
