Thanks Fredrik. Yes the timing machine correctly detected the proper beat. I think it’s either a loose cannon pinion or someone before me replaced one or more of the train of wheels with the wrong one. The results on the timing machine are decent, which I understand means at least the hairspring, pallet fork and escape wheel are good. Please correct me if I’m wrong. I’m looking for advice on how to determine is it’s a train of wheels problem. Cheers. -Norm
