It runs like a champ but I can’t change the time because the minute hand arbor is too worn . I am attaching a picture. Is there an option to repair before replacing it?

    First thing to do is determine what may have caused this in the first place. There is a tension spring that allows the minute hand to turned to set the time. Is it too tight causing the wear on the arbor. Most of these minute hand arbors have a metal tip to prevent this from happening. Could the wood tip here be a repair where the metal tip was replaced with wood? What does the rest of the arbor look like? I see brass at the base of the wood tip. The brass tip may have broken off, or was damaged at some point and was replaced with this wood tip. To repair I would make a metal tip on the lathe as a replacement. If the rest of the arbor is wood you can cut the arbor off further down, reduce the diameter, and sleve the new tip over the reduced part of the arbor. You can use a cross pin through the metal and wood to hold it in place. Repairing it with wood will most likely result in the problem returning at a latter date.

    Agreed. Don Bruno is the one I would recommend as well. Ken was faster getting this response to you.

    I have maybe 100+ wooden tall case movements, and I can't say that I've ever seen a brass minute arbor tip that I thought might be original. The usual repair is to replace the tip of the minute arbor, and from then on advance the time by pulling the bonnet forward and moving the hands with a finger on the easily accessible intermediate wheel. Between the inherent weakness of the wooden minute hand arbor square, and the weakness and break-proneness of original pewter minute hands, this is always the best approach.
