I bought two 48” pieces of 1/8 steel rod at tractor supply, cut them in 12” sections and started by making the big bend around a 1” pipe. The other bends required a vise, vise grips and pliers and lots of trial and error. Heating the metal caused it to fail and break. Made one from copper - too soft to hold anything, but damn sure easier to work with.
Finally wound up with some that look like they will work. The photo has an original, the copper one, one about 1/8” short and the keepers.
