·Hello! I’ve got a couple balances for 321s that have hairsprings that need some work.
Does anyone have any diagrams/drawing views of the hairspring with overcoil & terminal curve shapes?
ive started to try to use some others I have for reference but having a drawing would seem to be helpful for an ideal start.
also if there is some correct terminology or if anyone could help know if something like this exists, I would greatly appreciate it.
thanks!
