Iamsmooth: Yes, that will work. Tesla coilers have built a whole bunch of contraptions to allow adjustment of rotary gap phase over the years, look in the TCML archives for details. John Freau's electric phase shifter (the gizmo that ... described) is popular right now: instead of mechanically moving the motor or the electrodes, it phase shifts the current to the gap motor.

I found the site and can see it is quite simple using an LC circuit. I read the vague description for choosing the capacitor size. Should the capacitor value be close so that its full reactance matches the inductor reactance at the maximum setting? I am guessing that since he talks about watching the voltage peak through the motor the impedance through the LC circuit is close to a minimum. Does this sound close to correct?
