I have never been able to find this man who designed this hv filter. But thanks man.
Found it at this website. http://www.hvtesla.com/terry.html
I didn't use the varistors. They act like a safety spark gap that never "opens" again.
I don't know which kind of plastic is this I used, it was just around and looked like a nice option. I think it is polycarbonate as it has a very light blue-gray color on the edges. Superglue loves this thing. I just sand it a bit and add 1 or 2 drops of glue.

That is a nice looking filter and you kept your safety/creeping distances long enough to avoid flash-over, I assume you are building a SGTC since you made a Terry filter?

I don't really planned the layout, because I only had a few pieces of that plastic, so the wires on the middle are a bit of a little mess. I was going to build a SRSG, but then I only had a universal motor, now it is a asynchronous rotary spark gap. I don't know if I really need that filter. I need to read a bit about solid state coils, it is not my area, that is why I don't post on these topics, which are the most commented.
