Thanks for the input Toyotero. I really like the idea of the angled tension braces. Once I have those on I will try to post a pic of me bouncing around on the rack. The lock pin is grade 8 as is the hardware I bought and installed, but I will likely go ahead and upgrade the hinge bolt too. As for the steel used for Jerry can shelf, it's 2" x 1.5" 14g used for warehouse shelving systems. Not it's original purpose, but like I said - I will go ahead a post a pic of me bouncing around on it when I get the chance. This is my Monday night after a 13 hour shift, so it will be a few days.
