    Hey Guys,

    So the latest thing I've built is a slingshot revolver frame, with the intent for it to be a semi auto single handed weapon for my war games. It operates on a similiar fundamental principle to Joergs gatling slingshot (ramp pushes pouch up to fire), however has a system where the ramp is actually part of a trigger mechanism. This trigger mech moves forwards and backwards, resting on the ammo holding posts themselves, thus allowing it to be semi auto single handed, as long as the barrel has some sort of force rotating it.

    Enter the problem; I can't get a spring or similar force that is powerful enough to rotate the barrel with enough force to fire the rounds and is capable of spinning the barrel around for all 6 shots. If any of you have any ideas, I would be very appreciative! Otherwise enjoy the video!

    Well, I solved that problem by adding a battery screwdriver. Springs would be way more complicated.

    Mmm yeah I've seen your battery powered minigun Joerg, however I was looking to make mine as light and cheap as possible, so I'm not sure if a battery powered unit would quite fit the bill... I essentially built this launcher including a ton of bandsets for under $10, so if I could keep the price low it would be easier to convince my friends to make it a standardised weapon sort of thing. Also war games can get particularly tiring, and every gram on your weapon counts!

    Thanks for your feedback!

    Well, the cheapest one on amazon is just under 20 dollars...

    Ebay lists an even cheaper, but a bit embarrassing pink version at under 15 dollars.

    Pretty cheap! Plus you can always remove it (I use a one-screw clamp made from plywood) and use it for its original purpose.

    You will have a very hard time finding a cheaper and easier method.

    I have always wanted to make something like that myself, and I thought on an idea. Try to make the trigger upward like in the "Two shots side by side sling x bow" video, and then it will be much easier to fire when the cylinder is rotating. For the rotating you can use the same mechanism as in cap guns. You can can also use Jorg's crossbow revolver mechanism. Jorg had made fantastic weapons, and it seems like he built the 18 century arsenal without using gunpowder or compressed air. Now I wish he or one of us will build the 19 century arsenal (dubble barrled shotgun and sawed off, single handed 6 shots revolver, repeating rifle and rapid fire gatling gun. All this without electricity, gun powder or compressed air. Only rubberband or spring mechanism). I also reccomend you to take a look in the videos of the rubberband guns of "OGG CRAFT" in youtube. Hope I helped you, and I look forward to hear from you if you secceed. Sorry for my bad english. Good luck!
