I have a grandfather clock that I built the case for. It is still in the box from when I moved here in 1987.We have: 2 grandfather clocks that run on gravity, 2 old clocks that run on a wound spring, one old clock that runs on electricity, and probably one or two battery operated ones.
The electric and old ones are in need to repair of some kind. They're right twice a day. Really love to hear the grandfather clocks chime.
It needs cleaned, oiled and tuned.
