Hey, that's a good idea! I never thought of using a metal T - that's definitely worth a try.
I had also thought about having a ss strip cut to the same width as the plastic brace (so my versa tops would still fit in the rim's recesses) but have the strip cut long enough so it could be bent at a 45 degree angle at each end and simply slip it over the existing rim/broken brace. The bent ends would go down & overlap the front & back of the rim. It would be much more affordable than having a whole rim made.
I'm heading out to Lowes right now to buy a shelving unit - I'll pick up a metal T while I'm there.
What epoxys are strongest? Any preferences? I think I'll post that question in the General Forum too and see if I get a consensus. Would it help to also sand the T to help the epoxy grip?
Thanks for the idea! I want to work on the tank right away with your idea, but I'm going to see the Hobbit tonight with friends - that's a bit more exciting right now - lol
