The four main frame members are 1/8" thick aluminum U-channel, 3" x 1".

I'm hoping the additional views I posted better show/explain how the axles are supported:

The bearing block is the same for all six wheels. We intended on making several sets of blocks with the axle hole located at different heights, both with and without bearings. With this, we could conduct experiments with wheel height, demonstrating what happens when all six wheels are at the same height, or when the center wheel is lowered by a 1/16" or 1/8", etc. One frame, many options.

Thanks for the questions...
