Yes.... some were standard tin cans. Size matters. I think you would be
hard pressed to get a small propane tank to implode. Something the size of
a railroad car is another story.

The danger of tank collapse not withstanding, your idea should give some
'extra' vacuum. After all, don't they use vacuum storage in automobiles
to
assist wiper motors (old cars) etc.?

Can a typical "125 PSI air tank" be used as a "buffer" of vacuum? I
have some applications in mind like desoldering, where I would use
vacuum intermittently, and it would be nice to use a tank to "store"
vacuum. I was thinking about a use of an air tank. Not sure if regular
portable air tanks can be used for vacuum, but my own feeling is that
they should be OK. Just wanted to double check. Thanks
