Using gage pins to measure clock escapement regulator lever adjustments

[Paul Jones]

I have a carriage clock with a tourbillon mechanism for the clocks escapement design. However, the design of the clock's regulator lever makes very easy to overshoot or undershoot the time adjustment because moving the lever only a few thousandths of an inch can amount to several minute per week time differences. I discovered I could measure the adjustment to one thousand of an inch per adjustment by inserting a gage pin in between the regulator lever and lever cage. I include a couple of pictures to show how this works.
