I have an unknown clock movement with time, strike, and chime trains. One of the mainspring barrels has some broken teeth and needs to be replaced. I have noticed in the past that mainspring barrels usually have a number stamped on them to referenc the size, but this one does not.
The Barrel size is as follows:
Barrel Diameter at the gear = 44.89mm
Barrel I.D. = 37.8mm
Barrel Thickness = 21.34mm
Arbor Diameter = 5.46mm
The mainspring inside was also broken, but it was easy to measure it and determin the right replacement.
The Mainspring size is as follows:
Spring Width = 18mm
SpringThickness = .44mm
Spring Length = 48.2 inches.
With all this information can anyone tell me what size barrel I should get to replace the broken one? :
Any advice is welcome
