I very succesfully used 1/2" lexan for a bigger wheel (13" with 8 contacts
that where 3/8" bolts and nuts that were later changed to tungsten) that I
spun to 1750 rpm. Personally, MY reason for the larger size was I didn't
have a 3450 rpm motor for high break rates, so I "adapted" and made the
circuit think the RSG was a 3450 rpm set-up by using a larger wheel. If I
had a faster motor at the time, I would have cut the size down 8" or so.

  A recent message has made me reconsider if Lexan is a good choice for
a SRSG rotor.  After making the protective shield from 1/2" Lexan I
will have a section left over that could be used to make a 6" rotor.
Is it likely the Lexan will fail when used as a rotor and I should
instead use 1/2" G10?  Also, why do so many people use such large rotors
(12" or so)?  I have a 1/2HP motor which will likely be overkill for a
6" rotor.  Is there a reason to have a larger rotor?  Is G10 as easy to 
machine (e.g. turn in a lathe to true up the disk) as Lexan?  I will
be using parallel 15KV NSTs.

  Thanks.
