When you make non gunpowder weapons at home, you are usually restricted to single shot contraptions or manual repeaters at best. But of course the ultimate goal is to build a full auto machine gun style weapon!

That is by no means very easy. Muscle powered weapons are simply not quick enough for a true Brat-a-tat action. Gas powered engines are too heavy and clumsy for a portable weapon.

Of course there are modern battery drills - plenty of torque in small packages, lightweight and affordable. It makes sense to use those as power sources. But how to turn rotational motion into a linear cocking process?

We finally, at last, had success using a rack and pinion mechanism. The wooden gears had to be reinforced with massive aluminum for a reliable operation, but the result is very convincing.

It is a reality - true machine gun feeling!

Now on to optimization.

Joerg my friend! This was some grade A ingenuity! I was glad you covered abrasion in the Q&A, I was thinking that after I saw the recoil of the bolt in the action. I'm was contemplating what other types of tools you might use in small size/high torque and thought of a reticulation saw, although I imagine you would need to either gear down to revolutions to provide time for the elastic action to recoil, or use a shorter bolt (and who really wants to do that!).

IMHO it will be much, much, MUCH more interesting, if you made it without all this this fancy new material and drill. It will be also much more challenging thing dont you think? Anyway really good job. But i still hope to see fully functional middle aged tech lvl auto crossbow.

Very cool invention Joerg! Ok... now impress me farther, by removing the power-drill component with something they could have make in the medieval age. Maybe a tension spool, that can last the full clip, before loosing energy?

This vid reminds me a bit about the chaingun from Unreal Tournament (1999). If not for the problem of not being able to gear up, you could've made it into a variable-speed full-auto crossbow. That would be impressive to watch.

That will be perfect to home defense. If i was looking down the business end of that thing i would shit my self and run like hell even though I have osteoarthritis in my left hip and not usually are able to run. Even short walks are painful to me because my hip.

you would be better suited to make a spring charged gun out of pipe with a magazine underneath. Taking the drill apart would help too. From there I would say just focus the motor on pulling the sled back for semi auto fire. It's too bulky otherwise.

i would love to see a video of you using a john deer for a DIY project of yours. i'm actually trying to make a little project using a big bag of rubber bands i found. and hopefully a wooden 2x4 to start on the project of my own. watching your videos has became routine for me on an hourly basis. eventually my friend and i might try to make homemade black powder for this diy project of mine but probably not get to that part any time soon. lol

Love the stuff you create. A man has to be able to protect himself and firearms are not always an option. The things you create are legal and can easy to make from every day items. Keep doing what your doing and I will keep watching.

For some reason you remind me of wile e coyote from the cartoons. Always coming up with ridiculously awesome weapons nobody would have ever thought of, but do make alotta sense. The only difference is yours actualy work. Love your video's and creations. Thumbs up from an amateur slingshot builder in the Netherlands!
