Scant Scavenging

Scant Scavenging
A pair of powerful leaf springs will provide the tension to the arms of the huge catapult. But the scavengers have a tough time finding the right components. And with no springs, the design of the arms is pure guesswork. Small springs can't shift heavy arms, but too large a spring could snap them. Eventually the scavengers come good with some old truck leaf springs and cable in addition to their rams.
