Here are pictures of my not so pretty but simple to use, cheap to make, hangers that have worked well for many years. I have a plastic 55 gal drum and use a 1 x 3" wood board with holes drilled in it that sets across the top of the barrel. I have a sheet of stainless steel curled as a liner inside my barrel, with a stainless steel piece of tubing bolted to the liner that extends above the water level to attach the positive clamp.
I use 12" long threaded rods, either 1/4" dia. or 5/16" dia. Wing nuts, hex nuts, and washers. For things with handles with holes in them, I bend a threaded rod on one end to 90 degrees and can attach a skillet through a handle hole. For other items, I have a heavy duty spring clamp bolted to one end of a threaded rod. I use the spring clamp the most on any and everything anymore, including Lids. By using threaded rod, I can also adjust the depth an item suspends into the soup if needed. Lowes for the rods, nuts and washers and flea markets for clamps.... ;D
