Nice!! I love the over-engineering for strength, yet the abundance of bottom (trash rack?) bolts may cause it to clog on the bottom....may want to consider adding a trash rack on the top in case it does clog from below or you get a very heavy inflow.
If you look at the sketch all the way at the top of the page, it shows one. I have all the materials, I just need to build it before it gets to the point where it is needed.
