We've had several threads dealing with sympathetic vibration in longcase (grandfather) clocks. Has anyone ever experienced the same in other weight-driven clocks? I am thinking specifically of an S.C. Spring 8-day column and cornice that I have. Periodically, but not always, I find that it stopped after about 6 days. I start it up and it will either remain running until I crank up the weights or stop again after some hours. Although I have not ruled out other causes (e.g., tangled cord, weight scraping backboard), I just wanted to sound out some of the more experienced to see if this might be a case of sympathetic vibration. It currently stands on a small chest that is fairly level front to back, as well as side to side, and the clock is in beat. I have attempted to stabilize temporarily with a piece of thick polystyrene foam, while I hunt out a piece of wood. The movement itself is in good shape, although there may be problems I am unaware of.
