Some of the wheels are friction fits in which case the low-friction areas are the holes where the shaft goes through the front and back plates. With brass framed clocks with steel shafts, the hole always wears in the direction of the force vector. I would imagine that a thicker shaft in our case (using PLA) would wear less. Steve do you have any quantitative data on frictional losses? Thanks, Andre Routh
Thanks Steve. The stainless bushings are a great idea, Do you think short lengths of steel tubing might work or is something more bespoke required? Andre
