I'd consider using a used propane tank from a torch.
One of the throwaway steel tanks.
You want to make sure you purge it of propane, but after doing that you
should be able to solder brass fittings onto it.
Those are good for a couple hundred PSI.

The little 8 oz plastic coke bottle can handle how many psi?
Many.
30 psi is less pressure than they hold when full of Coke (according to
the internet)

Like you, I have been googling. They'll goto 100 psi if you don't mind
the bottoms turning into hemispheres as they pop out, but apparently do
so with no ill effects on the bursting pressure. Since I'll have sense
enough to stay below 50 psig, I think I'll be fine. I just have to
cobble up a wire carrier (roll of chiken wire) to set it in, drill 1/8"
holes in the cap for a pair of brass tubes, and liberally GO-2 them into
the lid. Drill a 1/8" hole for another brass tube in the valve block to
pick up the air when its on, and see what if anything can be done to
make the fluid valve actually work. If I can stay below 5 to 10 psig,
little or no fog, and make an 8 oz coke bottle of fluid last a few hours
while little or no air blows out thru the swivel joints to overwork the
air compressor, I should be able to grin from time to time.
Thanks Andy.
Cheers, Gene Heskett
