I used 3/8" flat stock 4" wide. Used a torch and a vice to get the necessary bends I wanted. Turned out nice.

go as thick as you can. It's the same effort to bend 1/2 as 3/8 in a vice with a torch. Might as well go beefy, the added insurance is good. Besides thicker material take stress better over the long run.

I use 2x3 box .250 wall. Mitered and welded....never had a problem. Seen lots of heated and bent style ones end up tearing at the bend though.

Mine is made from 1/4" thick material, with some 1/8" gusset for some extra strength.

Did mine out of 1/2x4 flatbar. Bent in our 10' sheetmetal brake.
