Vacuum Chamber Construction

[Richard Hull]

I tested my hemispheres using a rubber gasket on an old bell jar plate. Check the construction FAQs for my fusor II images. You have so many ports on each hemisphere it would be tough. You would have to blank of all on each hemisphere.

Welding continues steadily, I've nearly completed one hemisphere. The welds need to be cleaned and checked for leaks, and one its quite messy, I might use a dremel to smooth it out. Other than that, simply running out of Argon is what halted progress today.

The good news is argon is extremely inexpensive. You must have a small tank. Mine is full sized and I have had it now for 20 years and used very little of it. I fear that when I need a refill, they will note the tank pressure inspection is out of date and charge me an inspection fee in addition to the argon. This is a penalty often impressed upon a small use welder. Big shops never suffer this as they exchange frequently.

I've nearly completed all the welding on my chamber. A single large weld remains, but having run out of time this evening it will have to wait.

Good golly miss Molly! Did you get a sunburn doing all of this welding?
If not, you did good....
