There's been a lot of talk here about materials for RSG rotors, but not
much about use of metal other than saw blades.  In the "good old spark
days" a lot of transmitters gaps used metal rotors, often but not always
of cast zink with the studs or blades cast in.  The hub was insulated
with an insert.  I think the same thing would work today.  Make a hub
out of almost any rigid insulating material (even wood) and use it to
insulate a rotating aluminum plate with the electrodes mounted in it. 
Also good for heat dissipation.

Just a thought, don't intend to build one myself.
