Well, disregard that last transmission. Now I need to know how to match up a new hairspring. I almost had it perfect. Almost perfect is never good enough for me. I hate that about me.
I had someone give me some leftovers from a passed on watchmaker that had a little box of hairsprings. (If I can find the box.) I believe they are all the same size with a collet set in them. What is the way you determine the size spring you would need?
Thanks for any help. Danny
