I would like to build a device to replace a 3w, 115v, 1 RPM motor that activates a micro switch every 60 seconds, that in turn sends a 115 volt pulse to a clock mechanism for advancement. The clock was removed from an old school house and installed by my father at our old home place some fifty years ago. It adorns the cabinetry above the stove and is a center piece in our old home. Prior to the simple micro switch being activated by the 1 rpm geared motor, a mercury switch was positioned to tilt every 60 seconds causing advancement. The motor is badly worn, reverses itself on occasions, and stays extremely hot. My elderly mother depends on the clock and I would like to find or build a simple device that would take the place of the old motor & switch. Surely someone has an idea. Thanks for your time in this matter. gw321cya@gmail.com
