Basic setup of the beam
You can use a standard, certified steel tape to create the baseline for your
setup. In the illustration below, the steel tape is laid perpendicular to the
scratch line of the take-off board. To ensure that it is perpendicular, we use
the lane boundary line. Since the take-off board must be perpendicular to
the lane boundary line, this serves as a guide for alignment.
We place the "0" end of the tape at the scratch line, and extend it into the
pit (preferably through the pit) to a distance that is approximately the
length of the longest anticipated jump.
Next, we set up the beam that will be holding both the spotting laser and
the reading device. Attach the reading device securely near the end of the
beam that is closest to the takeoff board. Attach the spotting laser to the
trolley that will move along the beam. Be sure to use a lubricant that is
workable on the beam so that the trolley slides easily from one end to the
other.
