    12" version. Found it at Goodwill for $10. It's as pretty as can be and seems to be intact. But it only runs for about about 15 minutes. I have enough experience to replace the mainspring if necessary. When I bought it, it was wound too tight and wouldn't run at all, but I de-wound it and it ran, but only for a few minutes. Can someone please help? Thanks, Jim

    Hi Jim,

    Welcome to the message board, and the fascinating and addictive world of torsion clocks.

    If all else is good, short run time is typical of not being in beat.

    See this article:
    Beat Setting 101

    Be sure to post us some pictures so we can see if anything else might be needed.

    Welcome Jim, Nice find for $10! If it wouldn't run when tightly wound but actually runs a bit after letting it down some it makes me think the mainspring is really sticky or dry. After you get the beat set as Eric recommended watch the escape wheel and see if it snaps pretty quickly when it drops off of each pallet. If it is a little sluggish you can let the spring all the way down then add some light oil to the pivots then wind it back up. if escape wheel is still sluggish then you are probably going to have to take it apart for cleaning and a closer inspection. Post some pics... we always like to see pics!

    Another thing to look at is over swing. After the escapement clicks, the pendulum has to continue its swing for at least 1/2 to an inch. If it doesn't do that, lower the fork about a mm, and see how it works. Remember, small adjustments make a big difference.
    I agree with Harry that the spring is probably dry and sticky. 400 day clocks require a smooth slipping of the spring leaves against each other because they move so slowly.

    I've come to realize that I've been putting way too much oil on my mainsprings. I had been using enough oil to make sure the whole spring was visibly "wet".
    Lately, I've been oiling the spring in the winder and then removing pretty much all of it with a clean rag. Basically, just a rustproofing coat is left when the spring goes into the barrel. It seems to make for a lot less jumping and popping in the lower part of the wind.
