All: Here are pictures of my metal track (Generally patterened from M60 track). I was looking to use aluminum for the tread segments, but for this prototype, I used PVC plastic. The segments are .25 X .75 long X 1.5 wide. It looks like the drive lug spacing is too close, so I'll increase the tread length from .75 to 1 inch. The pins for this prototype are brass, but stainless steel will be used later. The pins are .125 inch, and will be held in place with tiny, .125" retaining clips ($6 per 100) and a groove on each end of the pin. The PVC is plenty strong, and rubber pads will glue well to PVC, also PVC is a good bearing material. The alternative is to use aluminum, and cut a slot to glue the rubber pad in.
It looks like it will take about 1 hour per inch of track to build (I have all manual machine tools). It looks like it will cost about $.80 per inch of track. The track is guite flexable in two directions (forward flex and back flex), but very rigid in all other directions.
