First get your materials. I used four pieces of 12 inch long, 1 inch steel tubing, 2 pieces of 1 inch angle iron at 18 inches long, 2 3/4 inch electrical conduit hangers (available at any hardware store in the electrical section), several 2 inch long bolts with nylon locknuts, 2 pieces of 1/2 inch steel stock at 20 inches long, 2 pieces of 1 inch steel stock at 24 inches long and a can of rustoleum.
For tools you will need an angle grinder or a hacksaw to cut the metal, a drill with metal bits, a measuring tape, safety glasses and some wrenches or a socket set.
Special thanks to my brother in law for donating the metal stock and tubing. These could be purchased or scrounged.
