I love the costume. Looks amazing and totally sells the idea that you are a real 8 foot space marine. I have a suggestion to something you may want to try since you said that hands don't move. Why not try to use a wire pully system like the what you would find in a toy extention arm? you could make the the inner pipe you use twist lock into the outer forearm part. The hand would be able to twist left and right at the wrist any longer and it would make the arms a bit more unruly to handle but it could give you some articulation in the fingers. Love the costumes looks great and I wish I had one.
We were thinking about makinh working hands, but the fact is they would not do us much good. We cant reach our mouth to eat, and the weapons are too heavy for an articulated hand to hold. We are planning to make more hands in different poses, more fun stuff really.
The stilts were custom made, modeled off painters stilts. We made them ourselves because it cost less for the raw materials. The hands were built on 4-inch ABS pipe. When completed, we just slide the whole thing over our forearms. We installed handles in these to hold onto.
I understand your curiousity. My friends and I decided to vacuum form our armor so that it could be duplicated easily (we have made three suits and have parts for two more). The good part about this is that it makes the whole suit pretty lite... Your armor looks pretty tall as well; did you use stilts as well, or are you just tall?#
