"The mechanism: The wheel constantly pulls the spring back then releases it. The spring's convex shape made it easy to build. The ammo clip only has a 1x1 hole to fall down so the clip stops when there is a new projectile ready. due to the fact that gravity only falls down, when the barrel is in the highest position it mostly only fires one projectile. the mech is based on the one Sariel used in his tripod gun (actually the whole thing is very heavily based on that!) If I had another working M-Motor (I have one dead one), I would use it for rotation, but an XL was needed to lift the barrel due to its easy-to-use shape and the extra power."
