Nice clock! Thanks for sharing. What is it that causes the foliot to change direction for the next 'tick'? In more recent clocks there is a spring which assists reversing the motion of the foliot. I'm interested in how this clock does it with no visible spring. In the video it looks like the weight on the escape wheel pushes the pallet, which forcefully turns the foliot in one direction, until the other pallet catches in the escape wheel, the whole pallet and heavy foliot rebounds, and the cycle repeats. Have I got that right? Sounds pretty hard on the gear. Thanks again for sharing!
Are the wheel teeth involute profile? I am making a clock like this as I live in a cottage from about 1650, and I have made cutters for simple cycloidal form teeth. I made a 30 day regulator clock and converted the Imperial plans and cycloidal wheels to metric involute. It is amazingly accurate. I went to Salisbury Cathedral to see the clock there and they started it going for me.
