Love the notes, fully appreciate the design work, as well as the effort and clarity of the notes.
I only point this "typo" out, because I followed it, and had to partially dismantle the completed clock to replace the incorrect part.
In short .... Thank you Steve for a great design and the documentation to produce it. Hope this doesn't sound critical, it was after all my mistake, in not catching the wrong part before full assembly. The correct part was already cut to length in the parts tray. This incorrect part was made (without much thinking) late in the pre-assembly steps.
Please refer to page 26, figure 20,gear 4 pre-assembly.
the 3mm shaft should read 4.5"/ 115mm instead of 5"/125mm
Best regards ... keep up the good work
Thanks for reporting it. I will make the edit for the next time I make a release.
