I have some stainless steel coil to sell. 316L .035 thickness 25' 1/2 OD $45 each shipped. I have 2 of these.
You will need to coil it smaller to fit inside of a kettle. I successfully was able to coil it without kinking by wrapping it around a tree roughly the size of a corny keg. The problem with a corny keg is you cant hold it as you apply the leverage to wrap. The tree is nice and sturdy. Just make sure that it is more of a stump than a tree as you will need to slip it off the trunk once wrapped. I screwed a board into the tree over the end of the coil to hold it to the tree for the initial wrap. Worked perfect and took literally 15 min. I think the .035 thickness helped to keep it from kinking.
