This one seemed like one of the more accessible treatises on a complicated topic.

Thanks VERY much for posting this!

Bob, thanks, I'm glad someone was interested in it. Feel free to copy it,
print it out, make into a PDF, etc. One thing, don't use it for financial
gain. That's about it.


I just love that first paragraph on page 3.

Hairspring manipulation is all about practice and a great deal of patience in doing so, its one of the first thing you learn in watchmaking school spending a substantial amount of time just correcting bare hairsprings, progressing onto overcoil creation vibrating etc later on, some people will never be able to meet the required standards and fail the course within weeks on this alone, in the same manner as person will never be able to paint a picture no matter how much tuition is given (of course you can always call it modern art!).
I have seen all kind of gizmo’s to do hairspring work that often get big money, none I have seen yet are of any use, here is one I was given, you can rotate the lower pin and drive the other in and out, suppose to untangle hairspring, it caused more problems than its worth, cant beat two good well shaped pair of tweezers.
