sasd,
I think what I really like more than anything about this particular photo series is that you showed your research material. The original photos answer a lot of questions about what moved you. They also answer a lot of questions that are out there about tank treads and just how much sag should be considered.
The real life photos show a good variety of everything from tight and straight, to semi-sagging. And since all these vehicles show to be in active use and not sitting around for ages, it goes to show that tank tread sag varied a fair amount.
It would be great to see more works comparing the real photos with the finished products.
Thanks again for what you put up here.
