This post concerns the strike side of a T&S Terry-type movement. First, I have a Terry movement in a Terry Jr case (pillar and splat). I dismantled the movement, cleaned all the pivot holes (green, oily gunk), and reassembled the clock. It runs beautifully, and the strike side strikes the hour on the hour w/o skipping. The only attention I paid to the strike side when re-assembling was to make sure that as the center wheel turned, it lifted one of the levers (a wire) which in turned lifted another wire (to wheel S3) that released the train so that the weight would drop and the hammer would strike. All good. I have another Terry-type T&S movement that wasn't fully running when I got it. I dismantled the movement, cleaned it, and reassembled only the Time side. Runs with good motion to the pendulum (after a repair to two broken teeth). So I added the Strike train and did the same thing I did as described above. Only thing, the outcome is different. The time side continues to run beautifully. And the clock strikes the hour on the hour. Only problem is, the movement decides to skip some of the hours before the train stops. That is, the clock continues to strike into the next hour. The lever will fall into the slot on the count wheel, which I think would drop another wire into S3 and stop the train. But no, the lever rises up again out of the count wheel slot, and the weight continues to drop and the gong to ring. Then it stops. And when I write that it stops, it's not because the weight has run its course but because the lever has fallen into one of the hour slots on the count wheel and stopped the train by stopping S3 from any further rotation. If I assume that (1) all wheels are good (they are) and (2) the wires that trip and stop the Strike train are functioning properly (that is, not bent)--then do I have re-assembly problem that I don't understand? Am I not aligning something properly on the Strike side when I put the movement back together? Am I missing something with regards to S3 or the pin on S4? Because it sure does look like the Strike side is working properly except for continuing to chime when it shouldn't. I don't want to start bending wires that otherwise look fine until I rule out that I have a re-assebly problem. The Terry clock I've taken apart several times and always have success putting it back together. I don't understand why I don't have similar success with this other clock. Sorry for the long post, but I needed to describe the problem.
