I am new to the board and hope some day to be useful to others but at this time I don't have much to offer. I'm new to clock repair and have only two successful Cuckoo repairs under my belt. I recently purchased a broken Farmers Daughter cuckoo. I successfully cleaned and oiled it. I also rebushe'd the drum on the music box. My drum has an elongated slot that the stop lever drops into. This is a problem when adjusting my Regula 25 music levers. How do I get the fan stop rod adjusted so that it runs long enough to pass the slot on the drum? Everything is working but I am unable to get the music box to turn several revelations before the stop Rod inhibits the governor...Is it that sensitive? Now when the stop Rod falls away and the activation arm drops the lever s still in the slot and the box won't play.... Frustrated clock whana be..Help me please, desperate in Oregon.
