Roll cage as air storage for On-Board Air????

Anybody use their cage/bar instead of using tanks? Does it take a full cage for enough capacity or will a standard bar work? I have a York compressor and I will be mounting in on mine within the month and would like to do the "right thing" for the storage.
Thanks
Dave

I've seen it posted alot as a feature- but always sort of wondered the same thing myself

I get nervous as heck even having my power tank mounted in the back of my work truck, but never give a second thought about the compressor tanks next to it, or in my shop...

I like the idea of the cage instead of tanks because Jeeps already have limited space. Once you have tool kit, tow strap, first aid, etc, then the idea of storing a pressure tank seems too much.

CSP; You mentioned that it would be little storage. Could I still air up the occasional tire and blow a little dust out of the interior using the cage?

it very simple, really...

How To Calculate Volume In A Pipe | TutorVista.com

cliff's notes version: 'The volume of a cylinder is \pi r^2 h, where r is the radius and h is the height of the cylinder. The amount of air actually contained within the tank depends on the pressure that the gas is under, though.'

I've considered doing the air tank/roll bar thing myself with a 6 point cage. Thought about a pressure valve in the back so that would go before a pipe gave way in an over-pressure situation. But if the cage was built right, and the calculations were done right for pressures, I don't think it would be a safety issue at all. I wouldn't run a crazy pressure in it, but I wouldn't do that in a regular tank either. It's not like it's a propane tank that could be explosive. Even if it over-pressured, and the relief valve failed, it would only crack at a weak point, probably a weld. It's bolted down so nothing to fly around. You'd have to work out the water removal system from the 'tank' somehow, maybe a series of purge valves at each low point.

Thats the first thing that popped into my head.
off camber...rollover...BOOM!
i'd just slap a real air tank behind the rear seat and mount it securely.

I've seen a few that had front tube bumper, rear bumper, and nerf bars hooked together with air lines. Looked pretty cool with quick-connects welded on the front and rear bumpers. Seems like it would be easy to catch on something on the trail though.

My biggest concern would be rust from the moisture in the air getting trapped in the cage and rusting it from the inside out. Why risk causing damage to the cage that could result in your death from a weekend cage. A small 1-2.5 gal air tank has lots of mounting choices in a CJ from in the passenger area to under the jeep. If your wanting to create a air tank in something else besides a air tank then I would look at the bumpers since they are normally larger and therefor can hold more air. Just remember making a weld air tight is hard to do.

i would rather just bendup and hide some pipeing near the rockers or under the jeep because altho a crack and loud his is the most proable it could go verry wrong ... and the pressure in the pipe could cause the pipe to fail easyer

Good points guys. I think I will stay away from the cage idea. My restoration is not going to have any tube bumpers so I guess I will go with the storage tank in the back behind the rear seat. I will look around for some options on tanks.
