Don: I had doubts about pin strength also. The choice for 1/8 inch pins was driven by scale and function. It was hard to get the connecting link length, to conecting link gap, correct with a larger pin. I can push in the middle of the track and cant bend it, no matter how hard I try. I laid my prototype track down on the center guides, then pressed down, using my full weight (175 pounds), on each side of the track, and it did not bend. I think your anaylsis of the pin load sharing is correct.
