Bert -
Not to step on Gary's toes, but the photos are of the rotary gap
I built and am using in my large coil. The black motor is a 1750-RPM
motor modified to run 1800-RPM full synchronous. The rotor material
is black Micarta (phenolic), and the rotating electrodes are 1/8"
pure tungsten TIG rod. The latest re-incarnation of this gap now uses
a 3450-RPM motor modified to 3600-RPM full synchonous. The latest
pictures of the coil running with this gap are in my directory on
the funet server. (/turner) One of the 'bigcoil' images is a closeup
of the base, showing the rotary gap next to a few blue caps for
perspective.
