Re: How many rules does this catapult design break? :)
My son and I tested the latest version of the “compound catapult” yesterday; properly sized cylinder and trigger release (couldn’t exhaust air fast enough}. We hit 6/6 @ 27.5’ (video below) until part failure. We were setting range by adjusting pressure until bow limb deflection was the same as measured by a caliper. We were cocking to about 75% of max force. We are working on the load beam/pressure transducer feedback cocking mechanism…
