Attach the pendulum bar by sliding the pivot pin into the middle of the pendulum
bearings. Insert the pivot rod into the exact hole shown on the peg board (Figure 2a).

a)
Put the bumper on the car, as shown in Figure 3a. Use two rubber bands.
b)
Release the
car "backwards" with the rubber band part of the bumper in front.
Note:
The bumper pin on the end of the pendulum must hit the middle of the rubber band
(Figure 3b). Adjust the position of the track side to side to achieve the correct position. If the
bumper is not the correct height to hit the pin, you have the pivot support rod in the wrong
hole.
