Archived - Update For Demo Fusor

Post by charlie_mccartney » Sat Mar 15, 2014 10:39 pm

I am in the beta stage of my demo fusor, I still have a while to go but I am making process.

Currently I have:
(2) Huntington EV-150 Right Angle Bellows Valves
4 Way Huntington CF 2.75" Cross
CF 2.75" to KF-25 Adapter
KF-25 Bellows Hose
2004A Alcatel Pump with MicroTorr 11-D Diffusion Pump
CF 2.75" Blank
CF 2.75" to 1/8" NPT Adapter
1 Gallon of LDS19
100 cc of LDS-704
15kv 30ma NST
7.5 amp Variac
Metering System (created by Richard Hull)

I still need either an adapter for my HV feed-through or another one, and a view-port as the one I have is some kind of custom CF flange. I would like to thank everyone who had helped me get to this point and especially Mike Veldman who has donated the majority of my vacuum parts.

Nice collection of goodies! good luck. I think that right after the sphere, the flanged "T" is probably the second most favored professional vacuum chamber used in a real fusion attempt.

It was a truly amazing donation by Mike Veldman, unfortunately it is a custom sized CF flange for which I cannot find any adapters or flanges.

I am thinking about finding a laser scanner and recreating three mating flanges, then welding standard sized CF flanges onto that in order to make my own adapter. I would also have to find or make three custom copper gaskets. However I do plan on using this chamber as my final fusor chamber. Another option in my mind would be cutting off the flanges and TIG welding standard size flanges on in the place, in Texas there is a massive amount of engineering ranging from industrial to home-made so finding a welder wouldn't be a challenge. Let me know what you think would be the best route.

If it were me and I have what you have I would go cheap and get three circles cut out of 304 stainless sheet metal between 1/16 and 1/8 inch thick and TIG welded to all those large ports as permanent blank offs.

Before actually welding them on,. I would.....

1. Weld on a stub 2.75 conflat or a KF stub fitting on the bottom circle for the vacuum exhaust port and a 1/8 NPT female nipple for a TC vacuum gauge.

2. Weld a 2.75 or larger stub Conflat fitting for a viewing window and a fitting for the deuterium gas inlet port on another circle for one of the arms.

3. Weld a fitting or flange for my high voltage insulator onto the last circle to be placed on the other arm. Make sure this fitting is large enough so that your grid will fit through so that it can be changed or repalced attached to the HV insulator, of course.

Now you can weld the circles on permanently and start fusing assuming you have all the other stuff ready. I would not buy or weld on a single large flange adapter. Just use flat plates TIG welded over the Tee's flanges. Cheap and should work great if your welds are good.

Richard pretty well duplicated what I told you to do when I gave you the chamber.

Sorry about that Mike, I completely forgot, my bad. Thank you again for everything.
