"Watt" Micrometer

[Rich O Brien]

The engineering in the spindle arm is something else. Its so refreshing to see the inners working compared to modern devices.

This is so plug and play. You would struggle to disassemble and fix a modern micrometer and then recalibrate it yourself.

I could disassemble a modern micrometer but probably couldn't reassemble it.

@Rich-O-Brien thank you! By "spindle arm" are you referring to the lead screw that drives the moving anvil?
