Ursus marijanus
Trick I learned: fill the tubing with table salt. It reduces the collapse of the tubing’s volume. Water under pressure gets the salt out.I was thinking a valve might be a good idea! I'll add one. This soft copper I have is some older thick walled stuff....Heading out now to attempt and coil it around a 5g bucket. I think there's 40-50' of the stuff. And it's free!!!
~edit~ I wager you’ll need a stiffer mandrel. If that bucket is all you have, fill it with gravel to keep it also from going out of round. Bonus: gravity will do most of the work holding the bucket still while you wrangle the tubing.
