I am embarking on a journey to become the best uncle ever. My nephew has his 6th birthday next week and he is a maker with heart and soul. He got a scroll saw for Christmas last year, so I got the idea to gift him something to make with it, so I came up with the idea to build a wooden mechanical clock with him.
I am not an accomplished wood worker nor clock designer, so the probability is high that there will be some issues, but that is what making is all about, isn't it?
I will post some pictures of our building progress here, if and when the clock is finished and working, I will post the plans.
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.
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:
