Confirm the location of the lowest point by gently pushing the beam a
couple more times.
5. Adjust one or two legs so that when you tap the beam it rotates freely and
does not settle to the same location.
6. Repeat steps 4 and 5 until the beam spins without returning to a consistently
low spot.
WARNING:
Always wear safety glasses when using the Go Direct Centripetal
Force Apparatus to prevent injury from the rotating beam.
