If anyone else tries this PLEASE be sure you thoroughly rinse all the oil from the tubing & fittings using a good solvent.

A blast housing, e.g. doing this inside a very sturdy piece of pipe, is also a good idea.

I have personally seen a similar wall thickness tube explode from the combination of oil & O2. Yes, that was pure oxygen & not air, but the risk is there.

Wayne, if you include this as a suggestion via a Wiki link, be sure to put in safety disclaimers so Pelican doesn't incur any potential liability from recommending something like this. Even if combustion doesn't occur, a weakened tube or one with small cracks, combined with excessive pressure, could make shrapnel.

FYI, it was not unheard of during WW2 to have fatalities caused in diving training by the old-style oxygen tanks - remember this is in pre-scuba days - and the fittings not thoroughly cleaned of oil. Pure oxygen + oil, while someone is breathing in. Lungs exploding are extremely messy, I've heard.

Yes, it may be a sea story told by an old CPO, but it still makes one cautions.
