LOL, ya know, its been 25 years since i used a brake lathe in High School auto shop!
If youre turning a rotor that needs a hat, it needs to be installed on the hat then turned. With regards to Wilwood, the lug and rotor patterns are based on the center hole. So you can use that to establish the axis

My choice would be a big lathe with 4 jaw chuck. indicate the center hole and the rotor mount face for run out. Then install the rotors and turn both faces without removing it. That will produce a great rotor.

How bad are the rotors?
What makes you want to turn them?
