Today i was able to make the rsg disk. It is made from 1/2" tufnol and has 8 electrodes spaced roughly 2" apart.

Nice work!! I assume you are going to use tungsten rods set in those holes?
How are you fixing the electrodes in?

Actually the electrodes are going to be industrial grade hardened steel threaded studs because tungsten would be to hard to fasten to the disk.

Might i suggest using collars to lock the rods in place? Or possibly tapping a set-screw in from the edge of the disk, but ive never worked with tufnol so i dont know how tapping it would turn out.

Im not sure how well you can tap tufnol but i am using locknuts and i might tack one side with a welder depending on how well the nuts hold.
