OleScout, What I make small rings of different sizes is a course thread bolt like a 1/2-13 carriage bolt and an old steel coat hanger. Just put the bolt in a vise drill a hole in it so the coat hanger will slip through, then heat the wire and bend to fit in the threads, tapping as you go to put those forged marks on it. Use vice grips on the end of wire while heating and winding.I make several wraps, then cut them the length of the bolt and you have a bunch of rings. Hope this helps. Jerry
