How do I troubleshoot an old 8-day pendulum mantle clock, pendulum stops after 5 min., even fully wound, Any advice ? Answered
I have an old Plymouth 8-day mantle clock, chimes the hour and half-hour, probably from the 1920s. The gears/ springs/ escapement are mint inside, no bent, rusty, or corroded parts. I scoured local antique shops for a winding key, which I found for it. The clock ran well for one week straight until it stopped. Since then, I can't get the pendulum to run more than about 5 minutes! I leveled the clock, tilting it slightly forward or back, to no avail. I oiled the heck out of it, and wound the springs fully. It is a really cool old clock for my leatherworking studio, no batteries or electric needed, and want to restore it somewhat original condition. Any advice on this? Thank you for your help.
