Hello! I have some interest in clocks and automata and I'd like to try and build my own. One goal I'm hoping to achieve to have as long of a period between windings as possible and to create an entirely mechanical clock (no motors or electricity.) I was wondering if you could help with a few questions I have. If I use more teeth on the escapement gear, does that prolong the period I have between needing to wind the clock? For example, if I have 150 teeth vs 30. Does a longer pendulum mean more conserved energy? If my pendulum period is 2 seconds instead of the traditional 1 for grandfather clocks, does that mean longer running time? I know a 2 second pendulum is quite long, ~2.3 meters. Does a heavier weight increase the time between winding or does it just allow you to power more gears / features like a cuckoo? The barrel that the weight is wound on - does the circumference change anything about how power is distributed? For example, if the weight was wound up on a 1 cm rod (just as an example), it would unwind 3.14 cm per revolution (I think.) So a larger diameter - say 2 cm barrel, it would unwind 6.28 cm per revolution? Does this have an effect on anything? Can I conserve more energy in the weight by reducing the gear ratio between the main gear and the escapement? How do you re-wind the weight without affecting the pendulum? I think that's everything for now. I'm still unclear how to power the escapement and how the pendulum gets its energy from the weight but I think I mostly understand the mechanisms. Thank you!
