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.

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.

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.

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....:unsure:

Any advice, opinion is appreciated.

Thanks in advance.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
