Hairspring Stud (wedge shape)

[clockboy]

Has anyone got any idea where I could purchase a wedge shape hairspring stud (see pic).
It is for a Citizen watch that needs a new hairspring fitting as the one fitted is just un-repairable. The old stud has been been stuck with some short of glue & will not un-stick even with heat. I have sourced a hair spring that fits but I need the terminal stud. If not I will have to purchase a complete balance which is annoying to say the least.

Can't you make one out of silver steel?

That might be the way forward i.e. make one from a bit of brass stock or I do have some round studs (various sizes) but would like to fit a wedge if possible.

Can't you file one into a wedge.

No they ( the round ones) are too small. I have also some square studs but they are also too small. I don,t know if the the square studs available for pocket watches would work, if they are significantly larger then this could be another option.

Which movement? 

Seiko has similar stud on some movements.

Yes I did notice that. This is a Citizen 8200A i.e. not a valuable movement & if not fixed it will just go in my spares box. Just for future reference I would have liked to have sourced a supplier.

clock parts sales should have tapered brass pins.  they are used in watch case hinges. vinn

Have a few old 8205 bought from Ramon. I don't think i have any good balances left. But if i need to find some parts for Seikos or Citizen i use thewatchcollector on Ebay. Where to find those studs i have no idea? Cousins?
