This was something small I made to replicate a actual catapult. most people use rubberbands for catapults but i decided to try to replicate a more accurate mechanism by using a axle getting bent by a rope system attached to a ratchet. The spring on it aids the axle and prevents too much damage from occurring on the 12L axle. It features a dual action ratchet for the crank system. the small catapult can also achieve ranges of up to 25-30 ft.
About this creation
the catapult armed
the 8L axle allows for ability to change the arc of the catapult
Here's a video the catapult fails to knock over the targets but you can hear the projectiles hit them
