I have a Seth Thomas ships clock per photos. It was running when I acquired it but would stop - was very dirty. I dismantled, cleaned in the ultrasonic including removing the mainsprings and cleaning and greasing. I reassembled and am now testing. I have two issues but I'll start with the first. The strike. The countwheel counts out properly and the countwheel arm drops into the slots properly and stops the wheel. The cam lever is properly seated in the slot in the cam. Then I turn the center arbor and it pushes the counthook out and it properly goes into warning. But here is where trouble begins....once the arbor push pin pushes the counthook back the counthook does not swing back far enough to disengage the stopping pin on the warning wheel. I was thinking it was the metal adjusting spring pressing too far down on the arm of the stop lever but I don't know why that would need adjusting. Can you take a look at the pics and tell me what you think?
Picture number 5 is in while in warning and the sixth picture is where the arm is after turning the arbor. 20210622_144419.jpg 20210622_144430.jpg 20210622_144607.jpg 20210622_144753.jpg 20210622_144618.jpg 20210622_144716.jpg 20210622_144729.jpg 20210622_144815.jpg

Well, I sorted out that problem after thinking a little longer. You know, put it aside, then think about it. Turns out the wire spring on the lifting arm got broken during reassembly and i just wound what was left around it's arbor. Turns out that didn't leave it enough power to bring the lifting arm completely out of the way of the warning wheel pin and it stopped it. Now, I don't have any wire handy so I was able to wind one more loop around it and it works but not fine. I can hear the warning pin clicking as it goes around....but that was the problem. So, off to the hardware store to see if I can find some fine rabbit wire.

Sometimes putting it aside and sleeping on it (not literally) will solve the problem.
