Steps:

  1. Secure the fin can using two tip-to-tip layup jigs on a level surface and face jigs towards a blank wall
  2. Secure the bottom fin to prevent fin can rotation, then place laser level on one fin and point towards wall
  3. Mark where the beam hits the wall
  4. From the floor, measure height of laser beam emitted by laser level + record height
  5. Measure height of mark on the wall from the floor
  6. Rotate the fin can to test the other fins and repeat steps 1-5 for each fin
  7. Compare deltas in height (laser level height vs mark on wall)
