I think your question might do better in the clock repair forum. With no other information, perhaps it is skipping teeth on the escapewheel. Or you haven't moved the pendulum bob far enough. If we knew if it is gaining or losing, and how much, might be of more help. I'm going to move your thread to clock repair.
ok and if i knew if it is gaining or losing i would have an idea but its so off i never have found if its gaining or losing! i will check the escape wheel, and ok how do i post to clock repair, that's what i meant to do
it rang the hour then 15 min later it rang the half hour! so i guess its 15 min fast! but then it rang the hour a few hours later and didn't ring the half hour 15 min later! i lost track and never heard it ring the half hour!
We need a picture of the movement. Without that we're guessing in the dark about something that may not even be there.
We also need a better description of what is the problem. Because what you are describing could be erratic running OR some sort of strike/chime train fault. So, the question is: Is it running erratically? Or is it not striking the hours correctly/on time?
For a decent attempt at diagnosis you must have the hands on the clock so you can see if it's keeping time. If it's keeping time but not striking correctly, then that's where we can focus our attention & ideas. If it's running erratically, then that's a different area of the movement that we need to be looking at.
hello im back sorry it took so long i had some other clock to come first, i took my zaandam apart but it cant find any thing! it runs fine but doesn't keep time at all i think its the minute arbor nit moving the minute hand enough?
The exit pallet looks to be bent way out too much.
I can't see what the entrance pallet looks like.
With it bent like that so much, it will restrict
the over swing, causing the clock to run faster.
If it was bent out to increase inside drop, the
entrance pallet may also need work.
Do remember to anneal the pallets before bending.
I think nc means that the 1/2 hour strike occurred 15 minutes after the hour strike. So the clock is gaining 30 minutes every hour. I suspect it's skipping teeth badly due to that verge being bent so obtusely. I would expect some escape teeth issues as a result.
sorry again for taking so long my internet ran out! it has a pendulum and is not skipping teeth! the reason i think it is the minute arbor is cause i don't have hands still! so i cant see whats really is going on but that's my best guess?
the only numbers i found were 516. i got my pendulum from a parts company and a leader from a clock smith, he sid they didnt make the same one so he gave me one to make work i just had to cut a hole for the crutch. maybe that is the problem?
