Re: NEW Fusor V build under way.

Mark, you are correct. I feel the pain of having no fusion of a decent nature since HEAS 2019. Compounding this is the horrid failure of that first iteration coupled with the death of my Turbo controller. Like the phoenix all are rising from the flames of perdition. The turbo is fixed and fusor IV i...

NEW Fusor V build under way.

I pulled fusor IV out of retirement and am using it in a new configuration. This will be fusor V for all intents and purposes into the future, I hope. I have it under vacuum. Some small leak issues seem to be solved after 4 hours of pumping and adjustments. I attach images, (as usual, click on image...

#9 FAQ - Ballasting the fusor power supply

First, for any power supply using a 60hz neon sign transformer or an oil burner transformer of the Iron core type,(older types used and sold into the early 2000's), no ballasting is needed as they are self current limited. These are usually Demo fusor type power supplies. In these cases, the builder...

Re: Vacuum Chamber Construction

I use them on all my 2.75 conflats just like Frank. They are a real time saver, but at $6 or more per set of 3, I have never bought any as regular nuts are just fine. All that I have came off a number of surplus system disassembly efforts in the past. I guess I have about 4 full sets on hand. I used...

Re: Vacuum Chamber Construction

I'm glad you took my advice on just drilling out those threads to make it thru-hole. Threads are great and even demanded in tight or ill-designed conflat mountings, but plain holes with clearance warrants that a bolt that is snapped off in no problem. A messed up nut just be cut off without having t...

Re: Demo Fusor Progress

The gauge, of course, is no good in the sense it will not read your actual vacuum level. It will serve to tell you if you have a horrific leak, but will not tell you of you actual vacuum level. Talked about here in the FAQs. Based on your device which is more or less the Make magazine version, you p...

Contained in many FAQs are, how much power is needed, how much voltage is needed, how much sustained current is needed for both demo and real fusing systems, wiring diagrams, metering diagrams, etc. The polarity is also...
