SP14 Moon Phase Clock Build

I had a great time building this clock. I recently started studying mechanical clocks and had successfully repaired a 19th century Seth Thomas 44, a modern Howard Miller / Kieninger mantel clock, a 1970s Hermle Sear Roebuck clock, and a 1960s Korean 36-day wall clock.

The manual is spectacular. The discussion on friction and forces translated across the gear train are fascinating. I am an engineer, so I dig that kind of stuff.

I was glad I ordered the hardware kit from Etsy. It saves you a lot of time cutting rods to length and grinding a flat for the minute hand. Bonus it also includes the drill bits to ream the pivot holes in the gears to the correct diameter.

There are so many things to admire in this design. The adjustable stand-offs on the back adjust for imperfect wall surfaces. The wood screws work very well and can be removed and replaced more times than a machine screw. The illustrated color manual is done very well as are Steve's debugging videos.

Here are two very minor things I ran into or missed when reading the manual. Spacer 7a and 7b are not mentioned in the assembly -- only a spacer_7 (which is 7b). The fishing line attaches to a hook on the frame, but that is not mentioned. The winding key storage feature should also get some print as it is another detail that shows careful attention to design.

Took less than 60 hrs of print time on the Bambu X1C. The test cookies included in the design are another great detail that insures you are happy with your build.
