Manipulating Hairsprings - The iPhone Method


Recommended Posts

I just thought I'd share this as it may be useful for another learner. By far the most difficult thing I've come across starting out in watch repair has been correcting bends in hairsprings. I've got the right tools, the right light, a powerful eye glass and a pile of scrap watches I've been practicing on. But I found time after time I was just making the hairsprings worse. I think part of my problem is that I'm slightly dyslexic and I find looking at the spiral really confusing sometimes. But I had a bit of break through last weekend which has dramatically improved my technique. Quite simply, I hold my eye glass up to my iPhone lens and take a close up picture of the hair spring. I then make a cup of tea and sit and look at the photo, zoom right the way in and really think about what I'm going to do. This is so much more effective than hunching over the hairspring and straining my eyes for long periods and losing patience. Once I've really thought about what I'm going to do, I go back to the hairspring with a clear strategy, ie, slight bend in, fourth from the centre at 3 o'clock. I apply the bend, take another picture and repeat. I know it sounds simple, but it's been a huge help to me and I'm finally having success :)

There are some great videos showing the process. Which is essentially to grip the spring with a fine pair of tweezers close to the bend. And then very gently "stroke" the hair spring with a second tweezer opposite to the way it bends. I guess YouTube is blocked in Iran? Can't you use a VPN?

Vpn too is a moke here.

I am rather experience with hairspring manipulation, to think how less painstaking it would be using  USB microscopes is discusting. Your method is smart, making use of what is at most every body's disposal.

Yes, that is something I've experimented with actually. For me putting the spring on a clean white sheet of paper helps. The other thing that's confusing manipulating a spiral shape is the fact your correction will change the gap between the spot you're working on and the coil further out but the gap further in will always stay the same! And several times I've reversed that in my head and wondered why my corrections are making the thing worse :D

When it comes to H/S manipulation  putting the spring on a white sheet of paper helps all to better see what the hell they are doing, are you putting us on? 

Even this fellow :turkey: sees better what he ate , if put on a white sheet of paper. ha ha

I am Dyslexic but never considered it a barrier to manipulating hairsprings. After distroying many Hairsprings I developed my own methods.  For me stroking the hairspring with a pin works better than stroking it with a tweezer. Also a microscope was the other great help for me.

    • Polish it where the old part cracked as well. Get rid of the stress-raisers.
    • Sounds great! And yes, I would use grease for the keyless as well although treating the parts with epilame would make the grease less likely to spread in the long run. Not critical but won’t hurt. My current strategy is to epilame treat all parts getting in contact with oil or grease.
    • Hello everyone, for what it's worth, here is my approach: 1. Escape wheel submerged in Epilame, then dried quickly with a hairdryer. Then the final tip of the pivots are cleaned by poking into pithwood. The logic being that the Epilame is removed at the intended contact point (to avoid any residue that may mix with the oil), but remains in the areas where oil is not supposed to spread to (further down the pivot towards the wheel). The escape wheel teeth also benefit from having Epilame to keep the 9415 in place.  2. I use a syringe to treat only the pallet stones. I suspend the pallet fork with some Rodico so that the stones hang downwards. I notably use a rather thick needle where a drop WON'T form, but rather where the Epilame liquid stays in the needle tip, which I then dip into the pallet stones. It requires some practice to get the right amount of Epilame into the needle tip, but it works for me now. This way, no drop will "jump" onto the pallet fork and potentially go all the way to the pivots.  3. I let the movement run for a few minutes without lubricating the pallet stones... to scrape off the Epilame in the intended contact "channel". Then I remove the balance again and lubricate the exit pallet stone with 3-4 successive drops. See the "channel" that forms on the pallet stone in the picture -- not so easy to see, but it's visible.       I am conflicted about the use of Epliame in balance jewel settings. My impression is that the two jewels sufficiently suspend the oil (even 9010). Apparently Rolex recommends NOT to use Epliame there (heard from a former Rolex service center watchmaker), as it could cause additional wear. Apart from that, I follow specific instructions where I can find them. E.g. the infamous Rolex reverser wheels or sometimes (parts of) the seconds wheel. Exception: I'm currently servicing an Eta 2824 and will probably ignore the service sheet that recommends treating the whole keyless works with Epilame and then using HP1300... I'll skip the Epilame and use 9504 grease.        
    • I'm going to give this a try today/tomorrow on my UTC33/Seiko 66, thanks!
