With the head completed, I can judge how much mass I'll be dealing with for the head. The neck is identical in concept to those wooden art horse models that you may have seen: three cables threaded through multiple cutaway sections. It allows for the neck to bend in all sorts of fun directions while resembling a a knife rack. I opted to go with this design over any others since there's not much else that works and looks any better. Also, it works, period.
I split the neck into 20 minor sections composed of 5mm thick sections, and one large 30mm long section. From my understanding, the three bones near the head don't have much movement and the head will likely block the movement when angled down, so there's no point adding articulation that won't be utilized. I originally thought of making the sections 10mm thick, but it would look terrible and have poor movement.
To attach the neck to the body, I used another 4 card stack to make a mounting plate. Right now, I jammed in the conduit end and it's being held in place by that alone. I'll need to make some stabilizer structures to keep it from wobbling. I'll also need a more permanent and sturdy means of providing neck articulation for the top and bottom wires. For now, the neck can do some decent poses, but can't do a straight extend. The weight tends to make it curve.
