The Harris MK1 clock mainspring winder is underway, photos to follow. So far £0 but I may have to go mad and spend £20 to finish it. Hehe. -
One purpose of recolleting is to align the point that spring leaves the collet with the stud, obviously collet center is to fall on this line of alignment. In case the collet already aligns Ok, but it doesn't fit the staff, broach. I have seen collets just glued to the staff when its hole is too big. -
Wow, this is an excellent document!! Super useful. -
Oh wow, that does look right! You're a hero. Amazing reference book you have there!! What is that?

Not so fast- (didn't realize how many makers made this shape)- it actually appears to be a Nouvelle Fabrique (Tavannes) S.A.
