With hinges my friend. Just got back from wal-mart with my glue and paper. Here is whats on todays agenda. The main support that i will be placing everything on (my size) I have to work at three. So ill probably have to stop in the middle and continue when i get back. I should have pictures of it either tonight or tomorrow morning. I was planning on having the lower jaw open and close as well..Mainly by placing magnets as well with a free moving joint or sometihng. that way when its up it will stay in place, but when its down it wont be forced to come back up as well. In order to make my jaw move i will be using the mechanism you see below, but at the end of it will be a spring. That spring will be connected to the part of the jaw closest to it. So when the faceplate goes up, the spring relaxes and so does the jaw(it drops). When the faceplate is pushed back down, the spring tightens again and pulls the jaw into place. Hope that helps buddy
