Reprints of the Best from the Electrical Experimenter, 1916-1917 are
available from Lindsay Publications. (815) 935-5353. They carry a lot of
Teslas' work and other strange, out-of-print books. There are several
drawings for rotary gaps in the reprints. Maybe a plan or two and
description of construction. I built one out of plexiglas using my own
design and the HV jumps to the motor! I need to extend the drive shaft! I
mounted the wheel directly to the drive shaft of the motor.
I haven't had good luck on rotary gaps. The best performance I get on my
coil is when I used a series of copper pipes spaced about 0.030" apart. I
use about 6 or 7. I built a plexi chamber and use 2 muffin fans to blow air
across the gap similar to Jim Carbone's design. A picture was printed in
Popular Electronics (or Electronics Now?) a couple of years ago when they
talked about HV capacitor design.

I too, would be interested in any plans for a good rotary gap. I spent a
lot of money on plexiglas and haven't had good results. Good luck in your
construction project.
