Hello all! I’m a brand new NAWCC member and a novice in the field of horology ... but willing to learn! I’m part of a group that maintains our town’s 1906 Model 0 E. Howard tower clock. It was professionally refurbished about 9 months ago and has been keeping excellent time. Occasionally, though, the chiming mechanism “sticks” in mid-chime. Here’s a recent video of the clock “sticking” after 2 chimes at 5pm. The problem is easily corrected by either rotating the governor blades slightly or by lifting the pawl off the chiming gear. To stop the problem from happening, we’ve tried the following: Lubricated the chiming mechanism (hoping to reduce friction); Adjusted the governor blades (hoping to reduce air friction and speeding up the chiming process); Added a bit of slack to the wire running up to the bell hammer, allowing the bell drum to start turning and acquire a bit of kinetic energy before trying to lift the bell hammer. These have helped but have not solved the problem. We’re now thinking that the chiming weights are just barely sufficient to power the chiming mechanism and are occasionally unable to overcome the existing inertia/friction involved in lifting the bell hammer in the belfry. We’re now considering three additional actions: Offset some of the weight of the hammer by hanging some weight either at the end of the wire running up to the bell hammer or at the end of the chiming pawl; Replacing the current stack of square chiming weights with a cylindrical stack of weights, thereby removing a potential source of friction as the weights rotate in the shaft; Increasing the total amount of chiming weights (currently 218 lbs.) Can excess chiming weights do damage to the chiming mechanism? Is there a way to calculate the optimum weight? I’d be interested in any thoughts whatsoever on this issue.
