Just a note to let you see that the method works. 1/2 inch copper tubing wound around a propane tank. Less than 4 inches I.D. No kinks.

This is the method I have always heard of. Funny I thought filling tubing to prevent kinks in bending was a well known method.the one time I needed to coil copper tubing; sand fill with solder plugs to hold it in worked for me, and I was able to anneal it and melt out the solder plugs at the same time when finished.
It was not for electronics
I've also read that some folks use water and freeze it before bending.
Freeze the water and the pipe splits, ask me how I know!!I could wish I knew about freezing the water, but the deed is done
.
We know what you're really gonna do with that. But don't worrk, we won't tellI'll just pull the loops apart until I get it 10 inches tall and silver solder some nice, round copper tubing on the ends to make it fit the connections on the machinery. The compressor can shake for a long time before it work hardens the copper and fractures it.
I have neighbors that talk like you. I set up a camera tripod during a rocket launch and they say, "window peeping". I make a flex tube for a compressor and they say, "illegal still". I just don't seem to fit in around here.We know what you're really gonna do with that. But don't worry, we won't tell
Are you sure it's two stage? It looks pretty symmetrical.It doesn't look so cost free now. I'm going to have to work to get this thing right. Most of the threaded connections leak. I can fix that. What has me stumped is, "How does this thing breathe?"
I found what I'd call a transfer block, and that would make this a 2 stage compressor, but I can't see where the first stage inhales. Missing parts? Operator error? Where's the intake filter on this thing?
