Cuckoo Clock

This is easily fixed, or so it is I’m told, but I’ve been trying to calibrate mine for weeks. The pendulum weight will either slide up and down which is the case with mine) or vertically with a screw.  If the clock is running fast, move the pendulum weight down.  If the clock is running slow, move the pendulum weight up.  It is important to note that 1 millimeter of movement = 10 minutes.  For a slide pendulum, it is advisable to mark the back each time you move it. Mine is marked all the eff up!! The back of the pendulum is not visible during normal operation and it will save you time if you ever need to adjust the clock again. After adjusting the pendulum, you must let the clock run for a full 24 hours to see if the time is adjusted correctly. If at that point it is still fast or slow, repeat the process…
