When turning staffs, a JKA is invaluable and expensive. Fortunately, I inherited mine. There are crude alternatives to a lathe...like chucking something up in a Makita drill motor and using various grit sandpaper to make a pin. Won't turn a staff that way!! But, you can make a pin.

This is probably one of those circumstances where I could use a lathe to reduce the diameter of the pin, right

 I don't use a lathe to reduce the diameter of the pin I use something else but I'm a bit puzzled as to why is it too big in this particular case is that's extremely big? By some chances as the balance bridge off another watch?

@JohnR725 The balance bridge is from the donor. I don’t think it’s bigger…It’s probably the same diameter but the center is displaced relative to the center of the hole in the baseplate. Not by much, obviously. What I was thinking of doing was just “shaving” off the smallest amount possible from the side of the pin where I think it’s creating friction. But @nevenbekriev wanted me to wait, so… 🙂
