My upgraded RPC is up and running

Add capacitance to the low leg. Total and complete swag: 10 uF.
Hopefully someone with a RPC will chime in.

i build RPC's,
the output of a balancing capacitor would go to the low leg but is completely unnecessary for what the OP whishes to accomplish
capacitance should be 10 to 15 UF per HP for phase balancing
i have played with this extensively
 
Just an update for what it's worth. I got it all hooked up and ran my lathe, the mill is not where I can hook it up yet. With the 12" Logan running, the voltage didnt change from what it was with just the idler motor.

I added some duel meters that show the voltages and had hall sensors to read the amps. They were from China via the 'bay. I'm not sure how accurate they are. I know the voltage part is right because I checked it with my meter. I dont have an amp meter so.....there's that. I had a sensor on each leg, L1 showed 19 amps, L2 showed 17/18 fluctuations, and L3 showed 0 amps with just the idler and 3.2 with the lathe running.
 
I need to step up a rpc output from 220v to 600v. How balanced do the 3 legs have to be? The most powerful machine I have is rated at 3hp.
