    I have a Kern anniversary clock, it runs 45 minutes and stops (it is consistently 45 minutes, must have restarted it 30 times by now. The main spring is either fully wound or it is frozen, cannot get it to move with the key. Everything else seems to be functioning normally.

    I live in North Central Kansas, cannot find anyone reasonably close that works on clocks, and I have several of them. So I decided to take a crack at learning to fix them my self. Can't be much more difficult than turbine engines can they?

    Any suggestions on a starter tool kit would be appreciated. My main interest would be 400 day and wall and mantle clocks although cuckoos fascinate me as well.

    I'll move this over to the 400 day forum for more response.
    In the mean time, you can start here.

    Welcome to the forum, Leo! Could you upload a few pictures, good ones of the front and the back plate?

    One thing you'll like have to confirm is the clock in beat? It ticks and tocks as the pendulum rotates side to side. After you hear a tick going one way, note how far the pendulum goes past that point. Then on the other side of rotation, see how far it goes past the other tick. Those distances, known as over swing, must be the same.

    Here's a little bit on setting the beat:

    Kurt, Thanks. It appears that clockwise overswing is about 60 degrees and counter-clockwise is about 115 degrees. So I will watch the video on beat setting and get that set.
    Here are a few pix. let me know if you need more.

    If I can get it running, I will be looking for a new base plate as well.
