Re: [TCML] rotary gap disk

[Sfxneon@xxxxxxx]

How does phenolic hold up to RSG use? Can it, or G-10 be doubled or layered  
to increase thickness? I have some 1/2" phenolic and would like to make a 12"  
disk. Is 1/2" too thin for that size disk?

Acrylic is a very poor choice  for an RSG disk.  As you observed, it is 
brittle and would be dangerously  stressed in an RSG application.  Polycarbonate, 
a.k.a. Lexan, would be a  better choice, but still not as good as G10, as Lexan 
will soften if the  electrodes heat up.

If one has limited machine skills and equipment, a  propeller RSG is a very 
good alternative to a disk.  See mine at
