ok i think i figured out a simple way of doing this.
the TOW launcher just pulls off the side of the turret, with a bit of force. It's attatched by two thick pegs. My plan is to shorten the pegs so that they just barely go into the locating holes on the inside of the TOW launcher. That way they will still hold it in the correct place but it will be easy to pull the launcher off the pegs when i swing it up.
I'm going to use two strips of tin for hinges (from a Shrek soup can....mmm). I'm going to Loctite the strips of tin to the underside of the molded on hinges on the TOW and then to the side of the turret. Then i can just flip up the TOW and the stiffness of the tin will hold it up. To fold it down i will just push it down, the tin strips will essentially fold in half and the TOW launcher will sit against the turret wall, held down by the shortened locating pegs.
So basically the tin strips will go from being folded in half (when the TOW launcher is in the down position) to being bent at 90 degrees when the TOW launcher is in the up position. I tested a piece of tin and it took 83 folds back and forth before it snapped....so that should give this hinge mechanism a pretty good life, as i don't imagine i will open it and close it that many times; if the hinges do snap it will be a fairly simple matter to install another couple strips of tin and the fun can begin all over again.
