<br/><br/> "Correctly choosing a proper replacement main spring when a clock has missing springs (or the wrong springs installed) is a very common problem that clock repairmen often face. This book is a result of Hansen's work to answer some of those questions about choosing springs. It provides a methodology whereby answers can be found by using a set of look-up tables. It's a solution intended for the use of clock repairmen at their bench to find those answers within a minimum of time and effort needed for any given clock in front of them." -- Cover.
