    Electric GE mantle clock runs fast

    I disassembled and cleaned a mantle clock, lubricated it and set it up on my test stand. Overnight it gained about five minutes. Only thing missing are the hour hand and the Westminster chime hammers. The rotor is totally quiet and clock runs smoothly. Any suggestions as to why it would run...

    Jefferson Suspense clock running fast

    These "mystery" clocks seem simple enough, so hard for me to figure one running fast. Customer says he read somewhere that the chain is the likely cause. Anyone have a better answer? If it is the beaded chain does anyone know a source? Timesavers does not have any Suspense parts. Ed O'Brien...

    ITR slave clock power

    I have a self-winding International Time Recorder clock and want to obtain and add one or more slave clocks. The master plugs into 120VAC, and I know the coils for the self-winding system are 12-volt. How do I determine the electrical requirements for slave clocks?

    Large Jefferson clock

    Just got in a Jefferson Electric clock with a 9-inch by 12-inch dial and a motor at the top that drives a beaded chain. Whatever is attached to the chain and carries the hands is missing. This clock just came through a major house fire. I've never seen one of these and wondering of the...

    I accessed the movement on this Hamilton 21 because it was not possible to turn the winding arbor. Chain is fully wound onto spring barrel, so the spring is apparently okay. Wondering if anyone has encountered this. My concern is that someone may have attempted to put excessive force on the...

    Zenith 251NA Watch and Clock Cleaner

    I'm using Zenith 251NA cleaner in my ultrasonic system for the first time, having always used the L & R ammoniated product. I like the cleaning results but wonder if I am experiencing a problem. The solution in my tank has become very thick, like a soft gelatin. It takes several seconds for...
