I had a boss , he made "oil day tanks" out of them for use in industrial bldgs. Probably close to 50 bldgs. Boy oh boy did he get mad at me ,as, I refused to install them.
We use them for mufflers on Experimental aircraft... Specifically gyrocopters... Subaru engines are popular...
Cheap... and the exhaust sound is cool!

*The duct system keeps the house comfortable; the equipment only heats and cools (and dehumidifies)

joejax, I like that diagram!! But,these "day tanks" were up by the 20'ceiling, and they fed oil into 6 or so hanging oiled fired furnaces. There was an oil transfer pump at ground level that fed the "day tank" and a "over flow" return line from the ceiling mounted freon tanks. And the yo-yo boss was using 15% sil-phos to braze a brass MPT x MSAE fitting into the steel tank which according to AllState and Harris ,that makes a "brittle" joint.
2 1/2" emt, some sheet metal cut in circle for end. I welded from inside and sanded smooth the outside edges. Used a punch to make the dimples.
One I made for outside has been out for three yrs, plus. has faded, but very little rust since was careful not to have gaps water could get into. The auto primer likely helped,too.
As I read the actual law the prohibition is not on refilling. What is prohibited is transporting the cylinder after it has been refilled.
What is interesting to me that originally not-refilling relied entirely on the integity of the user to ensure compliance. But as soon as reclaiming became the law-of-the-land and recycle cylinders were routinely available for sale - the user intergity was apparently deemed to be lacking as anti-fill check valves suddenly appeared on all other cylinders. <g>

More importantly, it prevents back washing to protect the quality of refrigerant as well as hazardous pressurization. Those two outweighs the value you'd get from reusing the empty tanks.
If you didn't have check valve and accidentally opened high side into it, you back washed system's charge into the virgin refrigerant by the time you realize it.

Made a bbq grill out of one, cut in half slightly above centerline weld bottom handles to plate steel or something to provide stability, use top for lid, add hinge if desired. Used an old commercial condenser fan blade cover as a metal rack for cooking surface and drilled a few holes for air intake.
A buddy took 5 cylinders provided by your's truly and made a cool water gizmo out of them, one filled with water and then dumped into another, doing so caused the dumping cylinder to knock against another like a clunking bell. His wife put up with it for a summer and then it went to the scrap yard. He is on to higher grade projects these days, things people buy as art.

Man, I played hell getting these to post. Have been working on this for quite awhile, shortly after start of thread. It's all made up of junk I had laying around, except the 2 pipe fittings on the top tank and the stack on top.
Please excuse my awful welds, I am still learning and believe I am getting better. Some think my smoke pipes are too long and will not produce enough heat, I built a small fire and had about 180 to 200 up top and awesome smoke.
I'm still not done, need to fit the lids better, grind poop welds, secure grids, and paint.
The top is an old well tank. The bottom is 3 404 jugs, I burned both in a bon fire. The bottom most is an old condenser cover piece and the jugs are cut all the way out as a rectangle, with custom vent holes and damper.
Holding that up is pieces of a stand and a recycled ash catch. The stand is for a 55 gallon aquarium. The 2 feed tubes are from a futon frame. We have had some much needed rain so now it is a little rusty.
Hi im new here..im an install tech not an owner. Anyways at the company i used to work for was a guy who used the empty 410 tanks as portable camp stoves. Cut em in half, weld hinges on the back, weld a handle on the front. The carry handles of the tank are now the feet, and then weld brackets inside to accomodate a small grate. Hook up propane to the refridgerant orfice in the bottom or use coals.
