Our team currently has a 2 motor 1:1 puncher. It can shoot flags in little time. We are running into a problem where the c-channel that slams forward to hit the balls is too powerful. This loosens the screws on the trunks and eventually the trunks fall off. We tried adding anti-slip math to adsorb some of the shock but this didn’t help. Any advice would be appreciated.
Again, nylocks are your friend. If you don’t have/can’t get any, use long screws and put a tightened shaft collar next to the nut so it literally can’t loosen.
