I'm just wondering, what is the difference between a SRSG and an ARSG?  One 
of my future designs for my first rotary gap was to first find a suitable 
motor, then to make a disk (size depends on motor), put in some electrodes 
(number based on motor rpm), and drive the whole thing with my 130v 5amp 
variac. Am I correct in assuming this is an ARSG?
