Yeah, I know, sounds dangerous, hi pressure and all that, but here's my problem.
I maintain a 250 cu ft leased Argon bottle for my TIG welder. I also make vinegar and hard cider, both often stored in containers that aren't full. The best way to keep the liquid from oxidizing is to pump in enough argon to form a layer above the liquid that displaces the oxygen. CO2 could work, but I don't want carbonated vinegar.
All well and good to use argon from the large cylinder for the vinegar, but the weld shop and the vinegar dungeon are 100 yards and a flight of stairs apart and I don't feel like lugging it around.
So what I'd like to do is buy an 80 or 125 cu ft cylinder (anything easily carried), fill it from the 250cu ft bottle and lug the small one out to the vinegar.
Offhand, it seems that a stem and gland nut, from regulators, in each cylinder, connected to each other by a suitably rated union or a threaded connector should be a safe way to fill the small cylinder. I'm aware that the first filling of the small cylinder might include some air, but that's OK. The argon will displace the air in the vinegar container.
If anyone has ever done this, I'd like to hear how you did it. Or if you have a better idea than mine.
