Ok, here goes: Every modder has contemplated, at some point, the idea of having the side panels or a front panel on some sort of hinge, which in Transformer-like splendour, opens itself to expose whats inside (like a lambo door) My question is regarding the mechanics of such an idea. Obviously, for it to swing open, you will need a) something spring-loaded and strong enough to support the weight b) something to keep it closed and secure when you don't want it open. I was wondering if any of you had any idea how such a hinge would work, and where to go to buy such hinges and catches. (my google escapades haven't proved fruitful). Ideas I have had, so far include: 1. some sort of shaft inside a hollow tube, with a spring pushing it outwards (like an old bicycle pump) 2. a sort of half spring (which i don't know the name of) that has two straight pieces on either end, which spring back when they are pulled towards each other, similarly (I suppose) to the hand exerciser thingy you can buy from sports shops: http://www.aiyafitness.com/pics-inv-other/hand_exerciser_hand-grip.jpg Thanks!
