I've already built the propellor gap using the .125 and the entire device
is housed in a cabinet with an blower to keep it cooled. I'll run it and
see how it does because as you said, the 1/4" is really expensive.
Adapting to the larger rods would be simple, just a few minutes on the
drill press! Does anyone have the Geek Group capacitor chart that includes
the cap value using the SRSG? I have the one for the static gaps but it
doesn't include anything for the SRSG. As always, thanks again.

Tony
