1/16 Scale FrankenDiff

I've given up on making a functional suspension assembly - at least for now. It seems like every time I add another part to the assembly, and try to constrain that part, it breaks a half a dozen other constraints. For now I'm just going to use the assembly to provide feedback for the design of the beam pivots, springs, and spring hangers. I already found out that I'll need to make spacers for my torque rods, to get them to the correct length. My torque rods are a pair of M3 ball links that are screwed together with M3 threaded rod, and a 1/16" spacer between them.

I know that when the axles articulate, things are going to want to twist around. That's why they use the rubber bushings on the real deal. I've been wondering how I could easily duplicate that. I first thought of using silicon fuel tubing, but quickly scratched that idea - the tubing was too thick. My current plan is to use O-rings with a 1mm cross section, on both sides of the equalizer beam. I'll use a piece of brass tubing as a bushing. The bushing will also keep the threads of the mounting bolts from cutting into the plastic parts or the O-rings. If I oversize the 3 bores in the equalizer beam, that'll give it a little room to wiggle around when the axle articulates - I think.

I guess the proof will be in the building.
