I have a speed adjustment issue with a Seth Thomas Westminster mantle clock.
The speed adjustment is a tripod spring mounted on top of the clock’s balance wheel. Shifting the tripod legs to the right speeds the clock; to the left slows it. A brass nub on the balance wheel slides in a groove on the tripod that limits the range of the speed adjustment. I now have the nub at the full extent of the ‘faster’ setting but am still losing about five minutes per day. What can I do?
