Appreciate any and all input
You might be better off with round stock/re-rod etc as that 1/4 flat stock is not rigid enough for what you want it to do, take a 3ft piece and watch how much you can flex it. You can't do that with round stock or re-rod anywhere near as much and your only using it for support. IMHO. If you have a brake you can bend sheet metal into a channel and it will be twice as rigid as the flat stock and not weigh much.
