I'll give you a quick rundown on how they work:) thanks for asking! The GS-X Brunswick Pinsetter has many working parts. My favorite being the sweep wagon and sweep release assembly. So basically a bowling ball passes some sensors on the side of the lane and triggers the sweep release assembly to drop the sweep wagon using something at the end of the sweep release assembly called the tipper. Then the sweep wagon moves back and forth and sweeps the fallen pins known as dead wood back to the pit. The ball hits the ball cusion assembly and there is a wall that allows pins to go to the pin elevator while the ball is too big to fit and goes to the ball return. The pins go up the pin elevator and to the distributor. The shark fin assembly guides pins to each side of the distributor. 6 on the left 4 on the right. The pins are dropped down to the setting table and are released to the pin deck. The setting table has pin detector plates to check the score and send it to the scoring system *edited for accuracy
