I would like to know if exist a table of thicknesses for various vacuum levels or something like formulas to calculate it, I know it depends on radius (of shperical chamber) also from materials involved... Someone has to do this somewhere ! :)
can someone help ?
Scavenging for parts, I have the necessity of being alble to discriminate goods and bads.
I was thinking about few parts to use as source for spherical cavities.
1. Gas bottles like the ones used in welding or fire extinguishers;
2. Balls of giant ball valves, to be turned some way;
3. Industrial fuel tanks or scrap from implants like this;
4. ??? ...still thinking on this :)
ciao Daniele
