If you work with your hands long enough most of use have had to fashion a custom tool for a specific job. You have to be a great problem solver to get the job done. In regards to bottle gas, years ago when I was a telephone cable splicer we hauled around bottles of nitrogen to power our air wrenches. You could crank them up pretty high. Probably high enough to bust the air line if we weren't careful. We also periodical had to watch safety videos about how they could be turned into missiles.
