Hi , spent a 2 weeks or so working on a Gilbert crystal regulator. A total non runner . Dismantled cleaned .
The clock now runs . The half hour ding works. Now comes the crunch. It will bongs on the hour only once . & at 12 will bong for ever .
As it was a mess when I got it . I made marks on all the chime rods of positions to return them back to the original positions .
The counter arm counts up but doesn't reset @ 12 ..
I check that the 2 levers sit on the wheel stop & start . But I can't figure for the life of me why the flip arm doesn't trigger the stop.
I think it maybe the thin tension spring wound on the shafts are eather wrong or out of position.
Or I have missed something else.
I have taken photos but I don't think it will help as the pins and levers are to far in to show.
I was hoping that someone has braved one of these clocks . I think it just needs a small adjustment but can't put my finger on it .
I did look to see if someone had done a video on a repair. But only on the Arizona model . .
So any suggestions are welcome .
The clock part runs . Worse case scenario I can live without the noise. But I would like to be able to have it fully restored to its full glory. I have totally restored the case .
Thanks

Hi I managed to track the reasons.
The 3 pin pinion that operates the rack counter has to be exactly positioned to match the drop pin release . Really tricky adjusting. Also the securing disc has a small lock pin and was too tight replace with a brass wire in a "S" which allows for more end float & was stopping the clock on the pre strike. .
I have learned a lot on this Gilbert movement. Even though it's a 3 layer. It was built in a very clever way that it can be disassemble in stages . & the main spring sits in a sliding mount..
Thanks to all .
Ps the silver marks are only chrome timing markers for test .

Glad you got it, Raymond. Those gathering pallet pins have to be just right for the rack to drop. Especially if there are three pins.

Thanks . What I did to solve the problem was to give the 2 springs just a turn to give just enough power so I could run the clock free just using my finger as a break.
This alowed me to watch how everything was messing and what was sticking. Ok it might not be the pro method. But to watch a dozen wheels & levels. Timing the 2 small lock pins in just the right places is really fun .1 stop from going to the cuckoo clubhouse.
..
Now I have to reassemble it all back into its full restored case .
Setting the beat I know this clock has to be 100% flat & level on X & Y ,Z to run true . .

LOL!
I quit working on cuckoo clocks totally because they almost drove me there.
Don't ask me what I think about cuckoo clocks.. the last one I fixed was with a 10kg hammer. Hate them with vengeance..
