Hi KKC,
I loaded a dxf viewer on this PC. Here are my comments.
I like the graceful curves of the 60t center wheel. The large radius curves on the cutouts look best (to me) for wooden clocks. They are also easier to cut out and sand. The diameter of the center hub should be sized to match the size of the pinion that is attached to it.
I prefer the 5 spoke design of the hour wheel instead of the 4 spoke design on the 60t center wheel. I saw someone else post that odd numbers are more pleasing to them. I agree. The only change would be to increase the radius where the arms meet the outer rim. My thinking is that the size of your router bit should determine the size of the gear teeth. A 1/8" router bit would be able to cut a 60 tooth wheel with a diameter of around 4-5". The curves in the spokes should have a radius that can be cut by the same 1/8" router bit.
I am still struggling with escapement designs in my head. The "shoe" style escapement seems common on wooden clock designs, but looks too delicate (to me) in a wooden clock. My personal preference is for the "slanted triangle" shape of escapement. Sorry if I don't know the proper names.
Regarding your other question regarding gear tooth profiles. I have read that there are many tooth profiles that have only rolling friction when the teeth mesh. Two styles have become popular. The cycloidal shape is traditional and has an advantage that it is very tolerant of meshing as the clock wears and the gears move apart slightly. I was replaced by the involute shape when machines started cutting the gears. Involute gears are easier to make by machines. I don't think it matters which one you use.
I like that you are designing your own clock. To me, this is the most challenging part.
