My Clock Will Run But Then Stops
OK you successfully set the timing on your clock and she will run for a while but stops. Sounds like she is a prime candidate for a good cleaning right? Let's look at some of the most common problems before you decide to tear the movement apart for a good cleaning. Are the hands contacting the dial anywhere or are they hitting each other?
Is the pendulum rubbing against any other part of the clock? The gong is normally biggest culprit here.
Is the clock level both side to side and front to back? The easiest way to check this is to pick up a line level from your local Home Depot.
When was the last time you oiled the clock movement? If its been over two or three years, its due. If it is a newly aquired movement I would just go ahead and oil it. One thing I have found too with newly aquired movements is that most of them will run for a short time and then stop. There is no telling how long they have been stopped (20-30 years?). So what I have found best is to put them in a place where you can keep an eye on them. Then every time you walk by them and they have stopped running just give the pendulum a little push to them started again. Over the course of 3-4 days a good percentage of the clocks will be purring again.
If this is a new clock you just aquired and you have not seen it run before it could be that the pendulum bob is the wrong wieght for the movement. If the pendulum bob is the wrong wieght it can keep the pendulum from swinging as it should. If it is suspect wiegh your pendulum bob and then you can get one that is heavier (if yours is light) or vice versa.
Are there any obstructions?
Visually check the movement for any obstructions. I dont know how many times I have found a hat pin or paper clip in a movement.
If all these things have been checked and appear to be correct it may be be time for a good cleaning.
