Thanks guys! I put some major surgery into the forearms tonight. I really like one, the other not so much!
I took about one more inch of all the joints. The plast is so stiff, it did not want to flex. so the first one I glued and riveted one side (I know you guys hate them, but it is strong, and I am not going for authentic!) then I wrapped it with tape andheated in the oven. It worked OK, but warped a bit inbetween the rivets. The other I glued and riveted one edge straight, then heated that and wrapped it while it was hot. Much smoother bends.
Still, both will work OK for now. MUCH tighter on my arms, and a better look. I also shortened them one inch, and V cut the elbow bend. I went back and painted all my rivets white too
Getting there!
