How does the cue ball return work on a coin-operated table?
A. There are three types of mechanisms that trip a cue ball and send it to the end of the table and separate from the other balls. The most popular is the magnetic system. The cue ball is standard weight and size (6 ounces and 2 1/4 inches) but has iron chips or an iron core embedded. A magnet inside the table pulls the cue ball to the side. Next is and oversized cue ball (2 3/8 inches). A spring or shunt bar sends the ball to the side. The third system is a heaver or oversize ball that trips a balance and dumps the ball to the side.
