Hi Travis,

Maybe you should try lexan. I know a lot of people despise 
lexan because it tends to lose structural integrity -at- fairly
low temps, but I have had great success using it for the ro-
tor and stationry electrode supports of my 10 KVA pig driven
coil system. I use two(2) 3/8" thck x 10" dia. discs for the 
rotories in my setup ( I use two RSGs in series) and 3/8" x
2" long threaded brass rods for the 6 rotory electrodes in ea
lexan disc and 1/2" x 4" long brass rods for the stationary 
electrodes and heat sink them each w/ (3) 1/8" thk x 2"x2" 
squares of aluminum. I had one of the lexan discs made -at-
a local plastic fabricator w/ predrilled and tapped holes for 
the rotory electrodes for $65US. I can run this sytem -at- near
full-power for 2-3 minutes at a time and the electrodes get 
mildly hot but not hot enough to sizzle water.

Hope this helps you out.

Safe Coiling,
