I am new to clock repair. I was successful in the first few and it hooked me. I am building a craftsman/mission style clock for my wife for Christmas out of a movement I got at an antique show. I have the movement functioning quite well now. My question now is about pendulum length. If I have a movement that requires a pendulum of 9", where is it measured to/from? Second may be a question for some physicists. If the pendulum must be 9", is it measured to the bob's mass center, or where it connects to the rod? This could potentially be a huge difference depending on the bob's connection point. I have done a search on the bob's connection point, but the only answers I found were way above my head. Thanks all.
