Attached is a picture of the giant wheel for a Waterbury clock. The pin that holds the mainspring has worn down. It could tap the pin out a bit farther and file or should the pin be replaced ? I don’t have any pins but I assume a nail would work. How far out should the pin extend to catch the spring? My guess would be about 2.5 mm?
