Tommy: adjust the blinder open and closed positions

Steps

• With the game on, turn pot R2 (yellow) on the servo board to set the open position and R5 (red) for the closed position.
• Small turns are enough; the blinders move as you turn.
• Rest the apron in place without screws, taking care not to catch the blinders, and check the open blinders clear the ball arch and the wireform under the apron.
