How critical is it to use thin wall PVC? I could only find schedule 40
pipe in six inch diameter in my area. I simply sealed the pipe with more
coats of urethane than I probably needed. The rest of Richard Quicks
instructions were followed to the letter.
About spark gaps... I constructed a rotary gap electrode disk yesterday.
I used a hardened steel plywood saw blade which I grinded the teeth off
of. I then drilled holes in the blade and mounted sixteen electrodes.
The electrodes are made off threaded rod, mounted with 1/4 inch nuts to
the disk. I rounded the ends of the rod to provide a better gap
surface. I then sealed the nuts in place with two part epoxy to prevent
loosening during the expansion/contraction during heating. The whole
disk will be mounted to a AC motor with variable speed control. Will
this gap system be sufficient to quench a neon system, or should I wire a
cylinder static gap with it? Any help will be greatly appreciated!
