Can I make my own ConFlat flanges?

Every fusor and fusion system seems to need a vacuum. This area is for detailed discussion of vacuum systems, materials, gauging, etc. related to fusor or fusion research.

No need to PM me.....I know zero about CNC beyond how cool it is and expensive to own. I know lot about lathe work and milling and I know I would never make one more vacuum fitting during my lifetime for less than $100.00/hr!!! I would be glad to make you a single 8" CF flange for $2300.00. Nuff said....

Ameen I would advise printing off something like the following:

https://www.kimballphysics.com/multicf- ... dimensions

It contains most all the dimensions needed for making your own flanges. Your next step is to find someone locally who can help you turn those dimensions into a real flange, perhaps someone in that college's machine shop, or someone from another machine shop locally.

Hello,

I recall further back in this thread that John Futter mentioned that I can get some ConFlat flanges from China at cheaper than the material costs. IS this true? If so, can anybody reference where to get them? As well, would they be of any lesser quality than the average you can purchase from Kurt J Lesker? Would they perform the same in a vacuum (keep the vacuum at a low pressure)?

Thank You
