Custom Micro Spring Crossbow
Inventor Maciej Nowak wanted to create a crossbow unlike any other, and that entailed making one that fit in the palm of his hand. Starting things off, the main body had to be fabricated from a piece of aluminum bar stock that was then shaped with an angle grinder before being machined to mount the crossbar and pulleys.



A circular aluminum tube piece is used as a spring holder, while the spring itself is tensioned by pulling back sailing rope that rests on a latch of sorts. The latter can be released using a small trigger, similar to its real-life counterpart. Projectiles consist of machined skewers with hard metal tips from nails, strong enough to slice right through fruits and other objects.
