Clark, Sherman was my absolutely favorite a few years ago. Good to see one here. I will have to agree with Steve. Perhaps you want to re-cut the keystone bogie blocks out of successive aluminium sheets? Also, what holds the swing arms in place? How are the springs mounted on them? It seems you could add a piece of very strong rubber or a plate spring in the little area where they join, though the leverage is huge there. Or just connect the swing armplates from underneath with very strong springs.?
