Hamilton 992 movement seconds wheel (forth wheel) needed

[jdrichard]

Does anyone have a Hamilton 992 movement seconds wheel (forth wheel)? Mine has a broken pivot that I may not be able to repair.This is before I failed at straightening it and it snapped. Going to try to repivot it but may be completely unsuccessful.

Someone has to have this part before I seriously damage myself trying to repivot the current one. The Jewel hole is around .24mm

Very difficult to find those hamilton parts for a 992

New evil plan. I will create a sheath over the broken shaft and pivot by drilling a hole in a piece of blued steel, just smaller than the shaft. Then I will friction fit the shaft inside the new steel part. Then I will grave down the long pivot to .24mm for the second hand pivot.

I always liked those pre 992B 992 movements, especially the ones with the concentric rings on the winding wheels. I don't know why I like those so well, I just do. I don't own one, but I like them. Congrat's on getting it up and running with the JD-pivot.
