Hi, I am a beginner and I need a little bit of advice. I am trying to repair a Seth Thomas number 89 movement. I dismantled and cleaned the movement however on trying to engage the main spring back onto its arbour I managed to break the arbour. This occurred no doubt to me applying to much tension with my home made mainspring winder! I would like to replace the arbour, ratchet and first wheel as one assemble simply because I have no idea how to remove the ratchet and first wheel off the arbour. I think I am in enough deep water already! Is there anywhere I could purchase this assembly, first wheel, ratchet and arbour so that I can just reattach the mainspring? Second hand or new is fine.
