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.

I have watched this video 5 times straight and had an epiphany! You can actually double your fire rate. God I am excited about this one! The key to the problem was you saying that gravity was too slow...So I went and made the gun an over and under. Gravity doesn't matter due to the rubber bands! (Lol, I say this like it's no big deal) Crazy as it sounds,but one gear can drive two cocking sleds without any more modification to the gear ratio or the sled return time. Just imagine another top unit with a extra gear to change the direction of travel of the second sled from forwards to reverse like the top. The additional gear I think may have to stay in contact with the second sled. I haven't quite got the gearing figured out but it should be possible.

Surely you could use a piece of tape, like what you did with the pencils, for a quick reload. You could fire all the shots, and probably reload within 30 seconds.....

PLEASE JOERG! Try making a smaller bullpup version of this for arm mounting! maybe with af curved magasine for smaller overall dimensions!! would be so cool! BTW maybe the powerdrill could be deassembled so that the motor kan be mounted directly and the you could have the batteries in a backpack! Just an idea but DAMN it would be awesome! no matter what you do, I must also say, that I LOVE your work!

Can you replace the electric drill with a high pressure pumpable pneumatic tank?
Can you make the magazine into a revolver like cartridge?
It would be much more awesome if it was a real crossbow. I mean the limb should store energy to propel those bolts not the rubber.
Overall, its a good prototype Mr Joerg

5:04 - Actually... Instead of turning the drill, you might want to consider turning the trigger or building a mechanical trigger that would push the drill's trigger... Even common sense says that if you can't solve it by putting the drill at an angle, just put the trigger at an angle...
You might even consider stripping the drill apart and moving the triggering mechanism to a different area., while maintaining the drill's motor in it's current place...

Point is, solutions exist without risking power loss.
