Final arms. Vent added to lower arm cuff, center split on upper arm cleaned up a bit, edge lips added. The outside elbow joint cover has been cleaned up as well, while the inside elbow cover has had a few polys removed for ease of build.
The only thing left for me to do is add a ledge on the inside of the lower arm cuff for the lower half of the outside elbow cover to join to, and that's simply a matter of cutting and pasting.
Please, if you see anything off, tell me!
Blowup view. The black cuff ring is a separate piece to help during the bondo stage. On the original suit this piece was actually an acrylic ring, and one of the only pieces of the suit (along with the shoulder rings, pistons, and internal joints/hinges/bolts) to really be a machined piece. The rest is a bizarre mixture of sculpted mechanical and organic curves, which is a major pain to try and reproduce.
Better view of the outside elbow cover. The intention is for this piece to be permanently attached to/act as the joint between the upper and lower arm. The actual elbow joint on the RoboCop suit is about an inch away from where it's sculpted. All part of the magic of hiding the man inside. And, strangely enough, the elbow joint was slightly skewed, turning the forearm across the chest when the elbow was turned. This not only allowed Robo to more easily grasp objects in front of him, but also enabled him to have more natural looking arm movement while walking.
