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.

instead of 90 degree adapter use a gear head off a angle grinder or just use battery powered angle grinder instead of a battery powered drill 220 volt angle grinder head powered by huge battery powered drill

@JoergSprave What you can do to have a in-line trigger is instead of using a 90 degree adapter is modifying the drill so that the trigger is separated from it, that would probably void the warranty, but who cares?

But you can add a 2nd cycle with an offset set of teeth on the other side of the circle that powers a 2nd sled with an independent magazine. It would make the whole thing bigger and heavier but also more badass and twice the firing capacity. Also if you really want you could just have the motor on the side and move the trigger on the conventional pistol grip, and also put the battery somewhere else. If you really wanted of course, but you'd have to disassemble the drill.

You should make zipper clips for loading. Such as all the bolts held together with tape. You load then pull the tape off.

hi you talk about the firerate of the gun so the way with more thees on the sear is write waht you have to do is you have to put more rubber bands on that the way for the same power is shorter that means also you have to build in a stronger motor in it im a airsoft player and in ouer buissnes this is called a dual sector gear maybe you wanne invest some time to learn more about this DSG and the it is no problem for you to but these upgrades to your construction👍🏼

Why do you have an extra trigger (activated by the gearbox) instead of the sled (the thing that pulls the rubberbands) and the rubberbands being fixed to each other ?
