Sorry I am taking so long to respond. I have started work on another clock, The Epicyclic wonder by Clayton Boyer. The plywood is home made from veneer and epoxy. That clock is of cherry veneer. The clock is about 6 ft. and the gravity escapement is very easy and simple to get going. All the parts are made om my new CNC mill If it were not for CAD and CNC I would probably not be building clocks. I am very lazy.
