I have found a bunch of good information here and plan on consuming it avidly, but I am also lazy and wonder if anyone else has seen this. I have a 20 year old Howard Miller 3-weight grandfather clock. I recently had it cleaned (no guarantees, no callbacks by the horologist) and after that, the chimes failed to -- well, you know -- chime. After a week or so we realized how much we missed them. Not wanting to throw good money after bad, granddad went silent. When the silence got oppressive, I removed the side panel and when I heard the "Click" at the 1/4, 1/2, 3/4 or top of the hour, I'd reach in and "flick" the little flywheel thing (yes, I promise I'll learn the nomenclature) and the chime would start, and do its thing. Sometimes it would even do it again. If I caught it at the top of the hour and had ignored it for an hour, it would obviously chime the wrong time and then fall silent while the autocorrection valiantly tried to auto correct. About a week ago, I vowed to get a handle on the woes with this clock. I downloaded an app on my iphone so I knew that when I was home and the app chimed, I should wander over to Granddad and figure out what's going on. I discovered that the culprit was the 3/4 hour chime. If I reached in at the 3/4 hour and flicked this flywheel thing, it chime reliably at the top, at 1/4, at 1/2 -- and then it would fail at the next 3/4 hour. As you can tell from my horrible command of this vocabulary, I'm ill suited to effect a repair, but I sure want to try. Is there something I might be able to do to make my clock chime again? Any ideas or suggestions? I promise I'm going to educate myself and hopefully make edits to make myself sound less like an idiot. Thanks.
