Here is a “clock model” I made based on the designs from stephenjressler.com:
I call it a “model” because it is not a working clock. It is not even glued. I see several changes I want to make before I try to make a working clock.
I learned a lot just piecing this one together, and I would really like to try to use printed axles. I just hope I don’t make things more difficult for myself by eventually doing that… It will require my clock to be larger I think, but that will be fine.
While reading, I learned about a “springed pawl and ratchet” configuration for a one-way gear that looks amazing! I was trying to use a gravity-pawl-and-ratchet system that might still work, but there is elegance with the spring that I really want to try.
A spring-and-weight pendulum system is really intriguing also. I think that could be fun, but a normal pendulum seems like the best place for me to start with.
