^{The original inspiration for this is probably this page: http://www.mocpages.com/moc.php/92430. It doesn't use long technic beams. I will point out that the tank tread had a small redesign after this was posted, so the technique works a little better with the older ones.}

^{P.S. It bugs me a little bit that you're attaching 1/2 pins to the tank tread instead of 3/4 pins. But I guess most people don't have many 3/4 pins.}

I am not sure if that is the exact place I first saw it or not, but it could have been, no doubt,

You are right, the half Technic pins don't work work perfetly. The 3/4 pins would probably be better. I certainly don't have a ton of them, but maybe I can scrape enough of them up to use them instead.
