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.

Just the sound of his voice makes me feel 30% less manly in comparison. He's like heavy weapons guy from TF2 come to life. I'm just waiting for him to yell "Who touched Sasha!?"

You can use rc brushless motors and gearing as they are stronger and faster. Any chance for the plans maybe? I'd love to make it in aircraft aluminium 😂

That is awesome!!!! Another question...why can't you just take the trigger out of the drill, solder longer wires to the connection and move it into the right hand firing position. I know you said it works fine for you but that would make it more comfortable to shoot i think.

Maybe instead of an adapter,use an angle drill for plumbing. It wouldn't lose any torque.
