I found a neat wall clock from Goodwill for a great price, only $25! It still had the pendulum and winding key, so a total bonus there. I had wanted a pendulum clock for a while and decided to seize the opportunity while I was in there.
After re-assembling it I lubed it with Mobil One syntethic 5W-30.
I also had to replace the screws that held the wall hanger to the case. The orignal screws had worn the wood and loosened. Rather than try to repair the wood, I just used a larger diameter screw.
I did start a time log to regulate the rate, by setting the clock to the exact same time (down to the second) as a known accurate clock. Then the clock to be regulated is compared against the reference clock daily. If the clock is running slow by a few minutes, the pendulum bob is raised by turning the adjustment nut and vice versa if it's running fast. This is repeated daily until it is regulated.
