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.

Hello. I am trying to make a crossbow with a lot of rifling to make a projectile spin very quickly. I am making a crossbow and I need the centrifugal force for a project. Any ideas of some sort of launcher that can spin the projectile? I do not like pressurized gas, but it is an option. Maybe a special fin arrangement?

This man is a genius. Every British household needs everyone in it to own one of these things + 100 bolts, (crossbow arrows), and detailed plans of to build another when they get made illegal and seized.

Every time you laugh, it makes me happy. That "Ha ha ha ha" is great! Also, there's actually firearms that have side handles like that, except it would be horizontal not vertical.

Super, super cool!!!! Q: Do you think that coil springs would work? That way you could make it more narrow. Also use a direct worm screw drive on the end of the drill allowing it to connect lengthwise like a traditional rifle. (Not a worm screw jack, but have a screw on the drill spindle mating to a worm gear rack on the slide directly.) And lastly, a snail drum mag that feeds from below! Wow! I can't stop! I'm going to make one! So inspiring and genius! Great invention!

Is this for sale? I would gladly buy it any day, especially the latest version, with mags. I think it would be great to see it on sale. The same concept, used for one made out of a light metal and springs or a sturdier component instead of the soft straps should work very good, along with a configuration to facilitate a professional mounting of a drilling machine but in this form is also amazing. My only concern would be its endurance. I haven't found something similar listed. I am interested whether is this classified as a crossbow and pass the laws for one or not.
