Hi John, welcome to the forum.
I just googled "wooden gears clock plans" and found an abundance of information and kits. My son and I have cut a clock out on our old CNC but did not have too much success, there was a lack of accuracy.
I do have the cutting file if you have access to V Carve and a CNC router. If not I think if you use google you will find what you want.
Hope this helps.
Cleaning my glasses will not make me look any better, but will make what I'm looking at better!
