Those of us who love clock repair share a common thought: clock repair is fascinating! After thinking about a difficult repair problem, we experience a sudden inspiration about how to solve it. Then we plan the work and carry it out. We go to the workshop first thing in the morning to check whether our movement is still running on the test stand. What's next? It's on to the next problem, of course.

Ed Sowers was a retired mechanical engineer who enjoyed clock repair as a second career. Approaching it as a business, he still enjoyed every minute of the work, and he didn't begrudge the time it took to repair every clock properly. His concept was to repair the entire clock, including case retouching if needed. Escapements were a particular interest for Ed, who was able to study and adjust every aspect of these mechanisms. He was a master at veneer repair, and he could cast and finish replacement case carvings. But the task he loved the most was an interesting movement repair.

Challenging Repairs to Interesting Clocks is the compilation of Ed's writings for three publications, NAWCC's Watch & Clock Bulletin, AWCI's Horological Times, and my monthly Clockmakers Newsletter. Ed was busy editing his articles into book form in the months before he passed away in February 2011.

Ed began every repair by studying how the mechanism worked. For example, he marveled at a "Terry's Patent" calendar device: how could so much functionality be achieved with so few parts? When a part had failed or been improperly repaired in any clock, he was able to design a replacement or an improvement that assured a long-running clock.

Many types of clocks are featured in the 32 articles presented. Ed Sowers covers a lot of ground in his 136-page book. Along the way, you'll learn how this master repaired cuckoo clocks, Atmos clocks, grandfathers, electromechanicals, American clocks, clock cases, and above all, escapements.
