All the structure most of the times is carved on acrilic and sometimes I make my own balljoints articulations. really dont know how to explain it, however here is a pic of one of the old ones I did in case it makes it easier to understand
As others have said, your custom work is really creative and very unique. I've always enjoyed seeing each piece from you, and this is no different
what kind of cutting tools do you use. if they work that good on diecast i can imagine what it would do to plastic
