• First plans iteration

    Yesterday, I finished a first iteration of the plans, containing most of the parts. The back frame, the fingers and some miscellaneous parts like spacers are still missing, I should add at least the back plane before my nephews birthday to be able to partially assemble the clock as we are going.

    It is just a PDF file with 1:1 drawings of the parts to be printed on paper, glued to the wood, then cut out with the saw and sanded. Below, you can see an an example (this is the ratchet mechanism used to wind the clock). The descriptions are German (and probably not the correct technical terms), so my nephew can understand them too.

  • The escapement prototype - a prequel

    A few weeks ago, I already build a prototype for the escapement mechanism, as that was the part that I was most unsure of getting right. It worked out okay, I got it to run on a 13 g weight on a 10 cm lever arm, resulting in a torque of about 13 Nm on the escapement wheel. I calculated that to maintain that torque I would need a weight of about 10 kg to have the clock run for 24 h (which is or at lease was my self-set goal). So there is definitely room for improvement, but I see the first and biggest obstacle as overcome. Below you can see a video of the prototype in action:
