Thanks. Mostly off the one in the attached image above which I think is the one we see in the Jawa's Sandcrawler in ANH. I didn't have a whole lot of time to do this any better and after posting released I missed a heap of details off. Anyway, I will probably have a go an making one once my Vac Form is up and running.Cavx, I like your design. Are you basing it off of a particular gnk?
