This book describes in detail how to repair and make the most popular clock crownwheel and verge, anchor(recoil), deadbeat and Brocot, with information on the more specialist types, such as the pinwheel, gravity and grasshopper escapements. Various types of pendulums and suspensions are also discussed. The emphasis throughout is on practical information, with additional advice on tools and jigs.
Probably the best book on this subject, it details how to repair, layout and construct multiple types of escapements from the antique verge, Black Forest clocks to more modern movements. Out of print according to publishers website.
I'm still thinking of building a clock, it would probably be one of his designs.
