Chapter 168

The workshop part of our October 2007 meeting consisted of looking at the driving force - springs. There's much to know about identifying spring problems, selecting the right replacement spring, doing the calculations for spring length etc. Barrel bearing condition is very important to make sure there is proper alignment and no binding with the first pinion in the train. There's always something more to learn. If you think you know it all, then why are springs rounded at the outside hole end and what is the radius based on?

Show and tell included discussing the restoration of a very corroded clock and a most interesting early Schatz quartz clock - see the pictures.
