Clock Progress: Rundown Test

The clock's almost done!

After fabricating the pendulum and pendulum staff, it's time to test the clock's functionality. These movements are designed to last at least 7 days, so after cleaning, cleaning, cleaning, pegging, cleaning, cleaning and recleaning the pivots, it's time to wind it up see how it does.

It survived! In fact, my clock died somewhere in day 10, which means that it's working perfectly. Lots of things can cause the clock to stop early, including bent/damaged pivots, dirty pivots and misdrilled pivot holes. Tiny depthing errors of just hundredths of a millimeter can cause enough friction to stop the whole thing in its tracks.

The next test is to have it run accurately (my rate was about 30 minutes fast over 10 days), and then we'll be putting on the final finish.
