I am working on a musical,water wheel and dancers Cuckoo Clock. The complaint was the weight on the music box when wound fell right back to the floor. I enlisted another Clock Repair Person to fix the problem with the click. He did that and went ahead and cleaned and oiled the movement. Pick it up and he said I don't know why but it won't stop cuckooing. So It is my customers clock and I have not worked on cuckoos much. I assume I need to remove the movement and see if I can figure out what I am dealing with before I buy a book on these clocks. What do I need to look for when I have movement out on my fixture? And anyone know which book I should buy?
