Hi all, 

Just wanted to thank everyone that responded to my G-10 
question. I picked up my 12" X 24" X 1/2" thick slab of G-10 
epoxy glass composite at a local plastics supplier and was 
only out $63. I hear that a 12" X 12" X 1/2" piece from Mc- 
Maser -Carr runs $50. Anyway, I was using the G-10 to re- 
place the 3/8" lexan stationary electrode support pillars that 
finally broke from heat, vibration and occasional striking against 
the rotory electrodes. With the 1/2" thick G-10, I was also able 
to cut a 1" wide strip of the G-10 to fasten across the G-10 
stationary support pillars to prevent excess vibration that could 
allow the stationary electrodes to come in contact with the 
rotory electrodes when the RSG was running. G-10 rocks! 

My two rotors are still constructed of 3/8" lexan and for the time 
being, I will leave them in the RSG, as they are still functioning 
properly. I may eventually want to cut two more replacement 
discs from the remaining G-10 to replace the current lexan ones 
and even replace the threaded brass electrodes with tungsten. 
I will most likely have to have the disc cut out by a machinist 
as I don't have the proper tools for cutting out a perfect circle. 

Anyway, I thought that I mention the $63 price tag on that 1/2" 
X 12" X 24" piece of G-10 from a local plastic supplier to anyone 
that was planning on purchasing some of it from McMaster-Carr. 
You may want to check with your own local plastic suppliers and 
see what kind of deal that they can get for you. As a side note, 
the local plastic supplier did have to order the G-10 for me as they 
did not carry it in stock and it took about a week to get it in. Also, 
the same sized piece of lexan would have cost me $49, so there 
was not a big price advantage to opting for lexan over G-10, as I 
would have thought.
