I just finished this piece, it’s titled “Up Draft”. After fooling around with several “flapping” mechanisms I settled on this configuration. Here’s a quick test before I put everything in place:
There was a bit of adjusting and fitting before everything came together. One neat feature, there’s a bit of spring action on the arm coming from the center post. This was intended to solve a problem where there was a bit too much push and pull. The result adds some nice additional movement.
Another brilliant piece! Fantastic movement. I wish I could understand mechanics like you! What fun it must be to compose with these elements.
This is my favourite piece of yours so far. All the components really came together.
What is the mechanism at the bottom that spins intermittantly?
That’s a governor for the wind up motor, it’s not moving consistently, I guess there’s a bit of stress on the motor.
