I'm a beginner looking for a cuckoo clock repair book so I can refurbish a clock with a Regula 25 movement (pivots and holes look ok, it's mainly just dirty, along with broken hands, decayed bellows, rusty chains, and some rust here and there). You might recommend I just buy another Regula 25, but the idea is that this will be a learning experience for me. I have Balcomb's two books, plus one by de Carle and another by Penman. Balcomb has a nice chapter on basic cuckoo repair, but not something in-depth concerning taking the movement apart. The others don't have much to say about cuckoo clocks. I suppose the movement is just a standard rack-and-snail weight-driven movement with a few extra bits, so general sections in the above-mentioned books might suffice. But at this early stage I need my hand held when reassembling a movement, particularly in order to get the striking system synched to the time system. Any suggestions?
