I'm sure it would be against the law, although a local comapny does/did sell 
a kit for freon bottles. Just for the record we did purposely hydro static 
test one years ago with a commercial testing machine used for gas pipeline to 
over 300 lbs before the plastic valve popped out. Have no idea how much it 
would take to actually rupture the tank. Stick with a carry air tank you can 
buy for less than $50 anywhere. If you MUST use some sort of salvaged tank 
I'd suggest filling with water and testing to at least 1 1/2 times working 
pressure. There are couple of easy ways to do this. One method: install a 
guage, fill PLUMP full of water, screw in a grease nipple. Attach your grease 
gun and go for it! I had a pressure welder build me a tank long, long ago 
from 12 inch gas pipe with proper end bells, the works. The dang thing was SO 
heavy you needed a fork lift to load on a truck! 1/2 in thick steel. I doubt 
if it took ten squirts with the grease gun to get the thing up to 350 lbs 
though! There was absolutely no give to the tank! Talk about over kill for 
100 lbs. air. 
Oh! Always install a pressure relief valve that can handle the volume from 
the compressor.
