[Amps] Corian for HV insulators?

[Jim Barber]

My neighborhood? Where the deer and the antelope play... ;-)

I can do the microwave test, though. I don't know if it will give me the 
answers I need for 60hz dielectric strength, but it will tell me whether 
it will work for RF insulators. Corian machines well and isn't too 
expensive when bought as scrap, so it's worth finding out.

The case is welded 1/2" clear acrylic, so my preference would be for the 
insulators to not be clear as well. I'm not sure why I prefer that, 
(since no one will have their hands in there) but I do.

Thanks,
Jim N7CXI
