RE: RE: [PSUBS-MAILIST] sub bouyancy

[Alec Smyth <Asmyth@changepoint.com>]

My main objection to propane tanks is that they are much too thin-skinned to
be optimal for a sub, even with stiffeners. Its tempting to use them because
they're so readily available, but you can get a custom made cylinder very
inexpensively, or even use a section of heavy walled pipe. There are lots of
suppliers, and they really don't charge much for a big cylinder or endcaps.
Steel is cheap.

I am in the same boat as you Bill, I am also planning to build a sub out of
a propane tank, but does anyone know of who has plans for such a thing
beside the kittredge subs.  Would those plans even work?
