Jörg Sprave, der Mann mit dem tollsten Lachen des Internets und das Gesicht des „Slingshot Channel“ auf Youtube, hat eine vollautomatische Armbrust geschaffen:
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!
