Bent hairspring

[Andraska]

Hi,

Am I allowed to post here with hairspring issue?

Thanks in advance.

I don't see why not! Pictures usually help a lot too.

Andraska, You are in the right place.

[Andraska]

All right then.I baught some watches for practicing and developing my skills.The watch that I opened up is a russian "Raketa" with 2609.i movement and after some examination I have find out that the hairspring looks a litle unusual to other hairsprings.I unmounted the hairspring from the balace cock and voila it is bent.

I don`t know how severe is the bending but the pined pictures will tell.Any advice or tip is appreciated for startig to fix this bending.

Thanks in advance.

This will depend on your skill. Working on h/springs takes a lot of practice. It is very difficult advising when its just a photo and you can’t see the thing at different angles. If it were me. I would start around the red arrow. You first need to get it on the correct side of the B/staff, and then proceed to shape it into the curl of the rest of the H/S. Don’t forget I cannot judge if it is bent high or low once it is the correct side of the staff.

That is badly damaged. Good for practice, but I'm not sure with my skills if I'd ever be able to get a satisfactory result from that. Metals "work harden" when you bend them, so it affects the characteristics of the spring, even if you manage to get the correct profile. It will be easier if you can get another god hairspring of the same type to compare to.

Thanks for the advice, i will return with the results.

Till then all the best and a great weekend.

Hi,

Sorry for the long delay of the results, but I`m back. So far so good I made some effort to sort the bending out.It is not an easy work to do but I liked it. The hairspring is far from being ready to be remounted, it still has some distortions that need repairing.Any advice, opinion is appreciated.

Thanks in advance.

You have done a great job so far, you must be a very patient guy.

The first hairspring to work with 

[oldhippy]

Its coming along. Just make sure you don’t sneeze if you’re working on it. I did once and what a mess I’d made, had to buy a new one.

Yes I have seen this and I want to proceed more or less just like in the video.

This is a super video featuring a russian Raketa watch. Probably one day I master this technic. Thank you very much

Not sure how he even did it. Tried that but only end up even worse. Looked pretty dirty before so i reckon he maybe just cleaned it when he did that. It was a bad example and just put it up as a not to do and fun video.

Oh oh,  @rogart63 , that one was a prank 

[Andraska]

Hi,

Back again. I come to a bottleneck in terms that I don`t know how to make the end curve. I made an imaginative sketch drawing on the picture taken of the actual balance bridge, "X" marks the maximum regulation point and thats where the end curve ends I think....

Any advice, opinion is appreciated.

Thanks in advance.

[oldhippy]

There is no easy way. to explain this. This I think will help you.

[Andraska]

Ok. I was searching this week and i found a site with a little different approach (to me) to make the end curve for the hairspring. I am wondering are these informations practical for forming the end curve?

Just like any other file from the "choose files" link below, or upload on a video website and post the the link.

[Andraska]

Hello,

So far I`m not satisfied with the results of the hairspring.I still have to work a lot with it, the video will show how the balance wheel wobbles.

[anilv]

The balance wheel issue is separate from the hairspring issue. Perhaps you accidentally moved it when you removed the hairspring?

Great job on fixing the hairspring!
