I am working on this HM single chime grandfather clock and I do not understand the chime timing. It has three pointed lobes and one long lobe. The lobe before the long lobe lifts higher. For the hour? Then two shafts with cam lobes inside the plates. I should have documented better, but I thought I understood how it all worked together. The cam for the 1/4, 1/2, 3/4 and 1 hour chimes is not installed in the pic.
