Antique clock...

I have a chiming clock. It's losing a few minutes when it chimes, about 4 mins out. We have wound it up in both keyholes, what else can we do?

For more on marking an answer as the "Best Answer", please visit our FAQ.If it has a pendulum on it there will be a mechanism for adjusting the weight higher or lower on the rod. This is usually a screw-type kind of adjustment: moving the weight higher makes the mechanism run faster, and vice-versa. Only adjust it for about 1 turn, and leave the clock alone for a day in order to see what happens. It's pretty much trial and error.
You're welcome, Sachs. These type of clocks are quite sensitive to changes in temperature and humidity. As I suggested, just make a minor adjustment and wait for a day to see how 'times have changed' so to speak. then, if needed make further adjustments. Two thinks to keep in mind about these clocks: never lubricate them with common house-hold lubricants, and never move the hour or minute hand backwards.
