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.

along the thinking of two piece keyboards and something else I'm forgetting your design, tweaked a few degrees could have you firing comfortably with both arms symmetrical like firing a large mounted gun

what you need to do is convert the front of your drill so that u can hold it normally and not sideways. it would give you a better grip and as for the ammo you could easily make a plywood magazine for quicker reloading
