why do you use a 3/4 HP motor on the rotary gap you describe - it
doesn't seem 
like there would be much wind resistance at 1750 RPM (which as you know
is 
really 1800 RPM with some slippage to allow for load) - it would seem
that a 
tenth or even a hundreth horsepower motor would be more than adequate -
there 
is no other drag beyond the wind resistance/fan effect is there???

A 5/8 inch thick G-10 glass laminate makes a good rotor disc.  For 5-15
KVA
systems use a 1725 RPM 3/4 HP motor equipped with 10 electrodes on a 12
in.
dia. disk.  3450 RPM seems to overquench.  We use 1/2 dia. brass thru
holes
