Sam,
Not a very good thing to try. at high power, the arc would heat the
material, leaving carbon tracks, thus making it conductive. I've seen a
similar design that uses aluminum and copper plates with threaded nylon rod.
The only reason that worked good is, the copper was used as the sparking
surface, and the aluminum, which the threaded rod ran through, was used as
heatsinking.
Although I've had good success with multiple static gaps, there are still
only two good choices:
Air Blast and SRSG.
Static gaps just don't have a very good quenching rate. And, because they
are fixed, the heat stays around and messes with breakdown voltage and
whatnot.
Back to the drawing board...
