I am going to run it at about 170 BPS, not 120 so it is a bit easier on the NST, I will have it on a dimmer so I can slow it down just a tad if needed. so correct me if I'm wrong, but 1700 rpms, with 8 rotary and 2 stationary electrodes would give me 170 BPS. If I do end up killing my NST, there are plenty of MOT's waiting for me at the dump... hopefully I will not have to go through that whole process. I am going to use some plastic from a cutting board, but I am not sure what size disc to use, my motor is rather large, so it wont loose a lot of RPM's no matter what size, but what do you recommend?

Hi Mike

   You dont want to use polypro or any equivelent of that material. As everyone else stated, it melts! Heres an example of a SRSG with a poor choice of material. BEFORE... http://host.teslamad.com/before.jpg and AFTER... http://host.teslamad.com/after.jpg See the washers under the electrodes on the disc in the first pic? Now you see the washers... Now you dont. I promise you they're still there, they're just embedded in the plastic now completely hidden. You want to look for a material called G10 or G11. Do a google search for it or check out this company http://www.electricalinsulationmaterial.com/ Its not very cheap, but you'll thank me in the long run!

Goodluck!
