We put three roll pins through the side plates that fit into the inside corners of the horizontal tubes. The fourth corner is used for a threaded rod to tie everything together. We started using this construction a few years ago, and it has served us well.

So the threaded rod crosses the entire chassis?

Yes! You can see it through the holes in the square tubes at the back of the robot.
Use one of the two bottom holes for the threaded rod. Gravity and the inside corner of the square tube will help everything line up. The oval cutouts aren't just to save weight, but also provide access into the tube to help align the threaded rod when assembling/disassembling.

This square tube + plate + roll pins + threaded rod assembly is one of my favourite "little-things" that our Design and Manufacturing sub-teams do.

Mr. Lim's dance moves were so fantastic they couldn't possibly fit behind one tiny smiley face.
