Galileo escapement clock

myminifactory

This is my take on Galileo's idea of a pendulum clock. It is inspired from that diagram that can be found on the internet. It is fully functional, runs for an hour or more depending on distance from the ground. And it does have a rewind key! See it live here: https://www.youtube.com/watch?v=9TbkEIbFsKk It is about 20" heigh, 50 cm,too big big to print, so I made the frame with wood. Steel shafts are 3/16, 5mm would work too, you will need some screws, a couple small bolts, washers, glue... Timming will take some adjusting, i started with a big block of wood, then shaved it down until it worked close to 1 tick per second. The way it is designed make everything adjustable. strat from the top, make sure all wheels move freely. The weight I used is about 1.5 kg, or 3 pounds. The weight, the pendulum, the lenght of the pendulum might vary, but you should have a good starting point here
