Adjusting the plumb-bob tilt
Steps
- Find the pendulum tilt on the left cabinet wall near the front: a cone-shaped weight on a wire rod hanging inside a metal ring.
- After levelling the game, loosen the two screws holding the ring and tilt it so the rod hangs in the centre of the ring, then tighten.
- Slide the weight up or down the rod (it is held by a set screw or clip): a smaller gap to the ring makes the game tilt more easily, a larger gap less easily.
- Play and adjust until the game takes a reasonable nudge without tilting.
