I recently started purchasing wall, mantle and grandfather clocks at used furniture store and antique store in my area that did not run. I get them home and have been successfully getting them running by cleaning (disassembling if bad) and oiling the clock. I recently told a friend I would try to get a Seth Thomas 1970's reproduction wall clock back operating. This is a simple single weight, time only movement and I am surprised by the trouble I am having. The gear train does not seem to be binding, there are no worn pivots or bushings in the plates but the pendulum stops after 3-5 minutes. I disassembled the movement and put the parts in an ultrasonic cleaner prior to reassembling and oiling. I believe I have gotten it in beat by moving it on the wall to the left but it stops anyway. The older #61 movements seem to of been driven by a string through a pulley at the weight based on my research. This movement has a wire cable instead that looks original. Any ideas why the pendulum stops? I have tried adjusting the verge engagement with the escapement wheel with the screw but this does not fix the pendulum from stopping. Thanks for any help you can provide this rookie.
