Twisted Hair Spring

[avkxyz]

Hello, 

I am trying to fix a twisted and bent hair spring. I am not worry about bent. but I have no idea how to twist the spring. You will see the spring is rising up from the center. Why all the spring rising up from inside to the outside uniformly. Where should I twist the hairspring? Thank you very  much for advice.  

 

This is a PP 16-250 lady movement. The balance is so small. The hair spring could not removed from the balance staff as it is very tight. I have to fix the twist hairspring with the balance wheel and staff.  

 

Thank you very  much for the advice.

David I hate to say it, but I'm certain you will have to remove the hairspring to stand a chance of correcting that fault. :(

agreed - I can spot several kinks and it is bent at the collet also by the looks of it. 

 

Not impossible to recover this but it will need to come off the balance wheel.

You know I had some luck with grabbing the end and rotating towards the middle, it's like one loop jumped over the top one. I know I never twisted it yet it looks like it's twister, sorry if it's not clear, I type like crap. Just use your small screwdriver and get just inside the twisted loop then follow the spring towards the outside end, and with tweeter grab the pin end, the outside and gently nudge the spring toads the center it should pop over and the you can follow marks video on coaxing the bends out

Hi Mark, 

Thank you for your advise. Fortunately, I removed the hairspring with a pair of screwdriver. Now... the problem is I have no idea how to adjust the hairspring. Please see below picture. I need your advise. Thank you very much.

Wow this is great, looks like your is a nice spot now, just some coaxing the bends out. I don't think you have to remove the roller
