However, we could adjust the catapult throw by changing adjusting a nylon strap attached at one end to the top of the catapult arms and at the other to a bearing sled that moved along slots in the main catapult frame. We could also move the spiral cam's distance from the shaft that it pushed on to change the overall crank-back of the launcher. Adjustable fingers managed fine shot tuning.
I would love to see detailed picture of what you are describing.
If you will be at Mad Town, I'll swing by your pit for a closer look.
