How The Clock Movement Wears.
These Seth Thomas Sonora Chime Clock Movements are made up of 2 separate movements. The first one is a Seth Thomas 89 modified to interact with the Sonora Chime movement. The 89 is made up of 2 brass plates with 2 springs and 12 gears between them. The Sonora Chime movement is made up of 2 brass plates with 1 spring and 5 gears between them. Each gear shaft has two pivots at either end that ride in a hole in each of the plates. As the mechanism runs, the pressure from the spring turns the first gear in one direction, that gear turns the next gear in the opposite direction, and so on. Which ever direction the pressure presses the gear to run, the pivot holes in the plates will wear in that direction. The more the holes wear, the more the gears drag as they move out of alignment, and the more power the movement needs to continue running. Eventually the movement wears to the point that the spring cannot supply enough power to run the clock. At this point the movement will need to be rebuilt.

How The Clock Movement Is Rebuilt.
First the clock movement is completely disassembled. All the worn pivot holes are realigned and then drilled out to the proper size of the bushing it is to receive. The bushing is then pressed into the hole and touched up with a bushing reamer as needed to provide adequate clearance for the pivot. (I use only high quality KWM bronze bushings) The springs are removed from the barrels, stretched while being scrubbed clean, and new spring oil applied. The movement is then cleaned and oiled, reassembled, and thoroughly tested.
