    it is called a crankshaft, not a drive shaft.

    Never thought of using a drill to power stuff before... could work for weaponry. Great build, I reckon you might just win this thing. You will probably get the top score in this round too...

    one person made a fully auto airsoft bb shooter that worked off a crank a drill would make that gun go crazy

    it would work very well for weaponry in fact. its exactly what you need for a powerful, fully automatic gun with a high rate of fire. i'd actually love to see one properly built ;)

    I might give it a go, I'm bored at the moment.

    so... how did it go?

    I'm still working on converting my PDW/CQB weapon into an assault rifle. Here's the base design:


    I know, but it's so COMFY!

    Indeed, it is comfy. Have you built the Knexsayer?

    Yep, don't have it anymore though, destroyed it for a shell-ejecting sniper. Still in progress.

    Nice. Is it your own design, or is it the one Bakenbitz has on KI?

    My own take on the theme. No copying.

    Ah, I see. Tell me how it goes, it seems really interesting :P

    My idea was for a bolt which pulled back the pin and the chamber cover, releasing the previous shell and allowing a new one to load, then pushing the bolt forward would re-cover the ejection port. It's very buggy, I will have to work hard on this one :/

    That's a pretty cool idea. The way the system goes, it will be single shot, yes?

    Yeah I've thought about using a drill for weaponry but it would be impractical because of how big a normal drill is and you would need to have it be a cordless drill to move around, making recharging batteries necessary too. I hope I win it, but like I said I have some tough competition.

    okay guy ive seen a lot of movies of u but i think this is the best if u want to see my video look at youtube: knex buick and then you get my engine plzzzzzzzzzz post this one because its cool and sturdy

    try and put a gearbox on it that wouth be cool
