Commpressed gas tanks

[weekend welder]

Is it possible to buy used/expired gas cylinders?? I would love to build a giant windchime.

Yup. Check with your local welding supplier or call some scrap yards. I have bought some off of the scrap man. Bob

weekend welder,

If you visit a local welding distributor and they may be a bit reluctant to let you have one or more, you could offer to bring a big hammer and cold chisel or a grinder and destroy the threads so it can't be used again.
This assumes they have already removed the valve.

I have 2 scrap 277 cu ft cylinders which were used for oxygen.

Both have no valves and one has the bottom 3" cut off so it may be useful for your project.

I was planning to make a big gong just like you but got distracted so I would be happy to give them to you.

PM me if you want them - FOBO - "free or best offer"

I am about 15 miles west of center city Philadelphia.

I also have a couple of those size oxygen cylinders, they make really nice sandblaster tanks

Note that acetylene tanks are filled with stuff in which the acetylene is dissolved.. Stick with oxygen and shielding gas tanks

If you can't find one cheap and fast, just buy a piece of pipe and and a weld on end cap. Weld, grind flush and you are in business.
