Truck: Rear
-Constructed the axle with 4" square tubing. -Made the truck bed wider, slightly over 4' to allow loading of standard size plywood. -Added 2" square tubing for rigidity in sides. Hopefully they are available, or another solution will be needed. -Still have to design wheel hubs. Bent rebar would be fast, but not modular. I am thinking that I will stack two 4" tubes on top of each other which will allow clearance and then lay flat metal across. This area is not load bearing. There could be a solution far lighter and cheaper not using metal.
MicroTrac: Tracks
The tracks that I had been working on were scaled down from the tracks off of the LifeTrac which was incorrect. Here I have drawn the component with the correct sizes for the track that will fit to the MicroTrac. I was unable to figure out how to include the dimensions for the holes; they are all 3/8" in diameter. The rebar pieces are all #2 (1/4").
I tested the rotation and it appears that even if the track components were both to rotate at a 45 degree angle they will still not interfere with each other. In the case of the tracks, they should never rotate that far.
The attachment/adjustment component should still work with this design. It will have to be redrawn to fit this new model.
While thinking about the adjusting and attaching I have wondered if it would be a good idea to have two or four points for adjustment similar to snow chains on large trucks.
