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.

It is there now, in clock repair. Your description makes me think it must be stopped, as it should be obvious with watching it if it gains or loses, if you start with the right time.

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!

You need to put the hands on it so you can see how much it gains or loses in 24 hours.

I think we need to start at the beginning.

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.

So, lets start there. OK?

Do you also have a suspension spring for it? Lacking hands, keeping time is somewhat of a moot point.

Some clocks are intended to strike on the 1/4 hours.
As Harold says, without some type of hand, we still don't
know if it is a problem with the strike or time keeping.

This looks totally stupid - but it worked for testing my 1st tear-down guinea pig movement. It's a piece of scrap 1/16" plywood I had in the workshop. The pendulum and suspension spring worked, too.

Yes Bill, that is hokey.
I've found that a piece of tape, cut in a triangle
makes a fine hand. I'm not to sure it works for
long as a suspension spring though.

NOT MY solder job! that's the BEFORE picture. Here's AFTER: After.jpg After-front.jpg That thing was a mess.
And it was my first tear-down, bushings, reassemble, etc. There's a thread somewhere here about it with more photos.

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.

its gaining, by i think about 15 min per 15 min if you know what i mean, its not a quarter chime but it rang the half an hour only 15 min after the hour!

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.

It is still confusing:???: 15 minutes in 15 minutes doesn't
sound right either.
Tinker Dwight
15 minutes actual time, but the hands advanced an additional 15 minutes, so they showed half past the hour.

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?
