Since this is the first time I have attempted this type of repair, I have been reading a bit on this, but am unable to determine where the first and second bends should be on the hairspring.Chicago school of watchmaking goes into how to raise the last coil so that it is level when the stud fits into the balance cock, but not much that I can see on where these bends are in relationship to the stud. That being said, I believe it should have an over coil, which is raised so that the stud will secure in place on the balance cock without deforming the hairspring. I was able to attach the hair spring stud using a taper pin (thanks Dave), but see that the hairspring should not be flat.In order to attach the stud to the balance cock, I have to raise the stud up and push it in slightly, which deforms the hairspring. The hairspring stud (wedge type) was broken off and taped onto the watch case cover along with the screw that secures the stud in place to the balance cock. I picked up a broken 16S Waltham Pocket watch.
