4500psi or higher tanks

Drew Sailbum once bubbled...
For high pressure cylinders, the importance of a proper design should be obvious. Unfortunately, some ignore this common sense safety precaution and rig up other pressure vessels for use as a bank. A couple years ago one of these systems (an old military bomb casing) exploded at Parrot's Landing here in Cayman killing one worker.

:wacko: Are you serious?!? :wacko:

Who would have thought to use a military bomb casing to hold compressed air? That's just... well a :boom: of an idea! (corny pun fully intended).

The point I was trying to make here is that the design of a tank has a lot to do with its intended working pressure, the abuse it needs to take and such -- not all cylinders are created equal!

Jury rigging a bank is unusual, but not as rare as I would hope.

It's prevalent enough that we've had more than a few of our new hires inquire as to the construction of our bank system before accepting an offer of employment.

I'm glad The Saint found his compressor had enough capacity as that banking system sounded less than ideal.

My answer would have been more dive cylinders since jamming air at 4500psig is really tough on a compressor, far tougher than jamming to 3000psig. More dive cylinders give you more options as well and may even be a bit cheaper, especially if you get your dive buddies to buy their own.
