I saw someones system for ball supply but does anyone have a system that also returns the balls? Ive got 2 pachinkos on the way and play on getting 3 or more soon so i would like to build a ball supply and return system. Im going to build it out of PVC and ive got the supply part down and know how im planning on building it but the ball return system is the hard part because im using 1 centralized hopper to supply 4 or 5 machines? if anyone has any ideas post them.
