The fins required precise measurements between each unit, and careful torqueing as they were tightened down onto the connecting shaft. The fins then had to be cleaned, connected to the driving motor, and fine-tuned with a series of adjustments to ensure smooth and coordinated function. We returned after the bearings had worn in to make further small adjustments to the motion of the fins.
