[PSUBS-MAILIST] Pressure Chamber

[Stephen Fordyce via Personal_Submersibles]

Hi Alan,
I leave water in mine permanently, but it's stainless so not such a big
deal.  If you put additives in, you'll also have to make sure they're
compatible with all the stuff you're going to put in it (ie. acrylic, seal
material, etc.), I reckon that's probably more important that the unlikely
chance of spontaneous explosions.

Alternatively, what if you made a kind of liner that could be filled with
water and save the water contacting the pressure-containing walls?  Could
be as simple as putting a plastic container inside, or a welded stainless
steel tube with end disc.

Cheers,
Steve
