Hi all,

I may have access to some uncertifiable oxygen cylinders (E cyl) that can no longer be certified for medical oxygen use, but are still in good condition. They are rated for 2200 psi, and should easily be able to handle 100-250 psi that we would use. The only dilema would be figuring out a manifold for it, but I have some ideas.

I'm not sure how much they would cost, and the supply would be sporadic at best.

How much interest would you guys have in such a thing? I'm trying to figure out if it is worth pursuing or not. Please let me know. If there is enough intrest (6-7 people?), I'll figure out pricing and see what I can come up with for a manifold.

Thanks

I would be interested single choice
	Absolutly
	Depends on price
	Not a chance in the world

My initial feeling is that they would be overkill. Too much weight for the air capacity they hold. I'm basing this on my experience with scuba cylinders which hold 2400-3500 psi depending on the model. Divers often use an air chuck and their regulators to fill tires. A filled scuba tank holds 80cuft generally. Fire extinguishers make a better option. See Roger Brown's site. They are light and hold about 200psi. At 100 psi you've only got a couple of cuft of 1atm air.

Good thinking though. It's nice to adapt "waste" to another use.

I think I would have 2 options. One would be a steel tank (which I agree would be heavy) the other would be aluminum, which only weighs a couple of pounds.

Looks like there is adequate interest for me to do some more research, so if your interested, send me a PM, and I'll see what I can do.

I have a $30 air tank from auto zone. It does quite well. I refill it with my cig lighter air compressor. I've also seen tube bumpers sealed up and then fitted with a quick disconnect and pumped up to around 125psi. I thought that was cool..........

Maybe fill them with helium and float across the mud...:scratches head.....hmmmmmmm

Back in college when I was still living at home, one day I was moving my CO2 cylinder for my MIG welder around in the garage. My mother came out and made some comment about wasn't that awfully heavy. I said it was and that it was getting heavier as I used it since the gas was lighter than air and helped lift it when it was full.... Had her totally convinced! <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />
