I wouldn't know how to calculate the bolt strength needed to deal with the loads.

Does your machine shop have welding capabilities?
When my father and myself were working on the Mountain Dewbot, we machined a bunch of brackets similar to the one in this thread out of 0.25" aluminum plate, tapped and threaded for 6-32 hardware to hold it square, and had the seams welded. As long as you bevel the edges (after tapping) where they'll weld, you'll get good penetration and have a strong joint.
