Fully Automatic Knex Gun (UPDATED)

FIRST OFF: DO NOT BUILD THIS GUN, ITS A PROTOTYPE!!

This gun is based off of bakenbitz idea and i just improved it and changed it around. Its fully automatic. It works by cranking. I made this gun to shot airsoft bbs but thats just because i like that so u can make it shoot something else if you like. It probably shoots about 3 or 4 per second. It comes with a clip that holds about 23 bbs. If enough people ask for the instructable than ill do it. It still needs some work but it doesn't shoot to far but its a brand new design and there is nothing else like it that i can find. hope you like it. please comment on what you think about it and if you upgrade it please tell me thanks.

    I've only got a little gear without tan connector hole, so mine slips cuz it isn't attached to the axle. How do I solve that?

    Get two stub connectors (small blue things with no hole) and try pushing them close up to the gear

    As the description says, it's a prototype. I built it too, it is very unreliable.

    Ow..... That's... Unfortunate.

    I won't make fun out of you. It is a commonly known fact that most full-auto's have a tendency to blow up.
