    Are the crank shafts geared to each other in that center hub so they the hub doesn't twist? Never seen that part disassembled.

    There's only one crankshaft, and the thing that prevents any twisting is called the master rod (which I believe is what you're calling the center hub). It is shown & described @ 4:37 in the wooden model video.
