Re: High Power SRSGs

Hi Gerry,

I've been thinking about trying using just the rotary
gap alone, without the seriesed stationary, since I do
have it better tuned and broke in now, due to the gap
loss issue that you mention.

I just predilled the holes big enough to slide the
tungsten electrodes in by hand and then drilled and
tapped a small hole from the outer periphery of the
disc to screw in a set screw to secure  each of the
flying electrodes in place. However, the red electrical
grade fiberglass material would tend to strip out too
easily so I finally just centered each electrode and
dabbed both sides with "Plastic Weld" epoxy glue. I
then had to take an angle grinder to remove the excess
dried glue on each side to regain decent balance of
the rotor. I would eventually like to get another disc
of G-10 or G-11 made for it and have a professional
machinist (which I am definitely NOT) drill the holes
set and press fit the electrodes for me.
