As the deadline of the Illuminate event approached it was time to test and tweak the sculptures.

We added the drive bike to the bird using some ‘dropouts’ made from scrap steel plate and old angle iron shelving. Time to test the bird and it proved too big for the poly tunnel so we moved it outside to continue work– the weather was changeable so we worked under a slightly too small gazebo for some of the day.

 

The bird wings proved too heavy and kept throwing the chain from the gear as they ‘pushed’ the chain forward ahead of the pedal. This was remedied by the addition of a number of ‘muscles’ made from old inner tubes, strategically placed these ‘muscles’ countered the downwards force of the wings and allowed an even resistance to the pedals allowing control of the speed of the rotation and flapping more easily.

Everyone was thrilled that the bird worked. The flapping motion had a real bird like quality and everyone enjoyed pedaling and making amusing ‘caw-cow’ noises…
