Rup/Greg thanx a lot, i knew if i posted this question here i'd get some great help. I was think along the lines of a very small ball bearing and the small magnets to give grevious the articultion he deserves. maybe in the pelvic, elbows, and shoulders. i'm thinking hasbro' s knee artic. on him is good enough. let me know what you guys think. and if anybody else wants to use the idea feel free b/c with the back up of WIP's i got going on i don't know when i'd even get started.
