Getting a grip
I am finding the components that require an interference fit of the shaft, keep slipping. I am using 1.5mm St St And drilled the hole a tight 1.4mm. I would like to see components that need to grip the shaft, have an integral boss to take a m3 grub screw. Or could you provide me the necessary files, to allow me to add it.
I am going to add to my clock some small magnets and hall sensors to provide feedback, to synchronise and lock to RTC.
I would like to have a twin stepper clock one for seconds and another for the minute train. That would enable self setting, from various time standards.
Thanks for some very interesting time projects.

The loads on the desk clocks are very light, so whatever you have should be fine.
btw, music wire is a common name in the US. It might also be called piano wire, spring steel, spring wire, or high tensile wire.
