I built a complete clock off of a sketch up swiss all wood before I got advanced software add ons. I spent two solid weeks and never got a tick.
It is a wonder it even looked like a clock.
I have looked a many escapements and played with making a few. Like you have not found a way to totally make them on the cw.
most i would cut out with the cw and hand drill holes through the top for wheel pegs from hobby lobby to fit in.
I did build Dick Bipes' " Mystery Clock". I like his escapement, it would have to be modified to work on a pendulum clock though.
