Odds are good I’ll post more photos about the clock and I still owe a full write-up about the restoration but that might bore the majority of you so I’ll just post a few collages.
The restoration had a number of interesting twists …
I ended up buffing out the damascened that had been applied to the arms of the escapement. The original looked like an after-thought and rushed. Re-applying a circular one would not have fit with the “simplistic” design of this clock (this clock was never of the design quality of a Seth Thomas).
The pilot face and the manufacture’s name plate would have originally been cast brass. I designed the pilot face and nameplate on the computer and then we transferred the data to a CNC. The finish was done with a 30/1000ths tool to give it the minor radius that would have occurred from casting. Lastly, it was media blasted to “age it”. I created a custom font for the job to replicate an old / simple casting. You will notice the numbers do not have perfect symmetry. This was a challenge to get something that did not look too perfect while also not looking like a child’s drawing.
Throughout the project, I got the feel this clock was somewhat of a “trial” for the creators. As such, it was simplistic in many places. I tried to keep that feel – while at the same time trying to refine it a bit. One example was the counter-weight to the Harrison maintaining power. You’ll recall it only had a cut piece of steel. This was replaced with a machined “barrel” of brass – made in two parts that thread together. The barrel duplicates the needed weight but looks more appropriate.
Eventually I’ll add the motion works to a 24″ face above and to one side. I picked up a small motion works rather than consider the monstrous one that belongs to the clock.
Right now it is keeping exceptional time – easily within 5 seconds per week. It has about 40″ of fall and I get 32hrs of run. Winding once a day is all it needs.
I definitely want to do this again. I’ll take my time to find the right project but I enjoyed the process and the results so much it will be hard to be patient !
