Check out the demo fusor by Gerado Meiro and Alex Garcia in Please Introduce Yourselves.
It is a stunner.
All homemade and works well.
They even homebuilt their diffusion pump.
Cudos to our Spanish counterparts.....salute!

Very nice demo unit and what an interesting and never seen central grid design. A real interesitng and significant contribution from a couple of newbies. Th' wheels are turning in a lot of brains now, I bet!
I would get a perfectly round balloon or rubber ball of the proper size, blow it up, helically wind the thing, (a bit finer that their grid), pop the ballon or set fire to the ball, pull out the residue and then reinforce the whole thing against heat collapse with a single diameter belly band of grid wire tack welded or soldered to every turn in the helix.
I like it.

Fusion is the energy of the future....and it always will be
The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment

Wonderful design! I love it. I especially like the fact that they don't have to do any welding on the inner grid! (As near as I can tell from the pic)
Definitely something to consider for us amateurs!

Watch out! I could see the weak point and noted it.
In a demo or real fusor this grid needs a longitudinal band or some such thing welded in place!
The entire mass of the grid is held aloft by the bottom most turn, remember. At white heat the hole mass would sink or tip over in a useless pile. We run white hot grids from time to time when doing real fusion or over exuberently driving a demo unit. If you just want to make a glow lamp that's fine, but star mode and real neutron production require a bit more energy than an unsupported helix might bear up under.
