"How To Fix Your Own Clock" gives simple answers to basic minor problems that can be easily corrected by most clock owners. This book is written for the typical mechanical clock owner who knows little about clocks - and who doesn't want to run up a repair bill if it can be helped. The book is in an easy to understand question and answer format, and comes from actual questions from the author's newspaper column. The author, Richard Hansen (a master clock repairman and owner of his own clock repair business for 15 years), knows that often, a clock may need little more than the correct set-up, or a minor adjustment to go from "dust collector" in your attic - to "treasured and accurate timepiece" in your living room! He wrote this book so you can get your clock going - and keep it going - easily and inexpensively!

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. From the beginning of his career as a clock repairman, Richard Hansen noticed that when his customers brought him their clocks to be repaired, he would often see evidence of poor repairs, poor techniques and even gross mistakes inflicted on them by previous repairmen. He wondered why he should believe that every spring he found was, in fact, the perfect one for the clock in question? And when he found a spring where the outer end had obviously been re-worked (thus making the spring a bit shorter), he wondered how he would know if it was not then too short? Was it possible to redo the end again, or will that make the spring impossibly too short then? This book is a result of his 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 with a minimum of time and effort needed for any given clock in front of them.

The Great Earthquake and Fire of 1906 is an unparalleled disaster in the history of San Francisco. More than 4.5 square miles of San Francisco burned and crumbled into a windswept desert of desolation. We will see this scene from behind the camera, covering before the earthquake through the fire and into the rebuilding of the city. The waterfront in the east to Golden Gate Park in the west and the marina in the north to Mission District in the south will be viewed. City hall and along Market Street through the center of the city will be covered. Stories from survivors and new information, like doctored photographs, will be included. Thirty years of research will be merged to give you an accurate account.
