Hi Guys:
Yup, 3:16 or so..
Theres a weight box hanging down below, that weight is strung to a wooden pulley on a wooden ratchet.
Gears are pretty easy , deadbeat gear is a 30 tooth wheel with an 8 tooth pinion. That turns a 64 tooth with an 8 tooth pinion, and that turns a 60 tooth. ( that will now rotate once per minute with a 43" pendulum , so thats the minute hand). On that shaft an 8 tooth drives a 24 tooth wheel with a 10 tooth pinion that driver a 30 tooth hour hand shaft.
Thats about all you need really. Theres lots of web pages out there to show how escapements work..
Later.
