OK, welded stainless it is.

I'm seriously considering going to a 6" Conflat cross that I have....that would permit about a 4" dia outer sphere. It's either that or get a bell jar, I think.

Why do you say, "good SHORT mean free paths"? Aren't we looking for free paths about as long as the diameter so the ions can fly all the way from the OD to the center without collisions?
hmmmm, in the patents I see a lot of stuff in about virtual electrodes that get much closer to the center...it that part of it?
Richard, have you written a Fusor construction tutorial yet?
