Question
My clock worked fine untill we moved today,I had taken of the weights and taped the pendulum and when I re=attached them the clock will tick for about 2 minutes and slows to a stop.I have balanced all sides.

Answer
Hi Paul,

Your clock is most likely "out of beat". This is the adjustment of the pendulum to make it swing exactly equal distances from dead center to the left, as from dead center to the right. If a clock is out of beat, the pendulum will swing for a few minutes, then stop.

Listen to your clock's tick. If a clock is in beat it goes "tick-tick-tick" like a metronome. If it goes "tick-TOCK-tick-TOCK", or makes no tick at all, then it is out of beat. Some clocks have automatic beat setting; try starting your clock with as wide a swing as possible. If it has auto beat setting it will correct its beat as it settles down to a normal swing.

If your clock does not have auto beat setting, the beat will have to be set manually. This is a delicate adjustment which takes some experience to do properly. You may want to have a professional clock repairer do a service call to set the beat. If you want to try doing it yourself, this is the procedure:

Remove the side or back panels to access the back of the movement. You will see that the pendulum top is connected to a strip of metal about 6 inches long. This is the pendulum leader. There will be another flat brass strip (the crutch) which comes out of the back top of the movement, bends to go straight down, then ends in a connection to the pendulum leader. This connection will be either a round post on the crutch going through a hole in the leader, or a forked end on the crutch going around the leader.

Now move the crutch to either side. You will feel a point of slight resistance near the end of the swing. Push the crutch past the point of resistance, just a tiny amount, probably less than you can see. If the uneven ticking sounds worse, or if there is no tick, do the same thing in the opposite direction of swing. Do this in small adjustments on whichever side makes the tick more even, until you achieve the steady "tick-tick" sound.

Adjusting the beat is a very delicate process, and it will most likely take a few tries for you to "get the feel" of the adjustment. But, if you do it patiently and in very tiny adjustments, you will probably be able to correct the beat.  http://www.clockmasteronline.com
