I hope for a good outcome! Let’s see the result, no matter what!

Thanks for the interest! Here's the position after phase 1: the HS seems to be shellacted into the stud & I didn't want to get into removing & re-attaching it; also I couldn't move the boot on the regulator to release the HS. Hence the arrangement at the outer end of the HS shown in the photo which gets these parts out of the way.

After trying to undo the tangle around the collet for an hour or so I decided the only option would be undo the whole HS from the outer end & I'm now at the last stage of that having worked back to the final few coils around the collet.....

Update: having this HS to practice on has taught me:

1. that after working for about an hour, I suffer from the equivalent of the golfer's 'Yips', those involuntary twitches which cause one to miss the 'target': in the present case that being a smooth 'bend' in the HS. Taking breaks is therefore important & doing so is also a reminder/opportunity to re-dress the tweezers which is, this practice has reminded me, time well spent

2. that I lack the degree of wrist articulation required to make vertical adjustments effectively.

What I intend to do now is to spend a little time in each session at the bench doing a little tweaking of this sacrificial HS in the hope of improving my technique as well as 'keeping my hand in' for when I have to work on a salvageable HS.

I've often wondered about making some die-jawed tweezers to facilitate HS work & I now think such a tool could ameliorate the problems caused by the 'Yips' so I hope to find time to explore that possibility.

The secret to good hand stability is wrist and finger support. Bean bags, sand bags, wooden blocks can be used for supports.

Another secret is using very light touch tweezers. A heavy tweezer will fatigue the fine muscle fibres in the hand and cause tremors.

Caffeine also causes tremors.

The blood pressure medicine, Atenolol, has a side effect of making the hands more stable. That's why it is banned from competitive shooting. I'm not suggesting that you go out and get a prescription of Atenolol when doing hairspring work. 🤣

Except when I need to twist the hairspring, I only use one tweezer in the left hand and a bent needle in right. Grip the hairspring a little behind where you want to place a bend and use the needle to stroke and shape the bend.

To prevent tremors, I work on a slab of glass. I grip the hairspring with the tweezers and rest the tip of the tweezers on the glass. The needle tool also rests on the glass.

I'm sure everyone have their own way to do hairspring work. This is only a suggestion. Try them out and see what works for you.

We have a thread where hairspring tweezers were discussed.

I cannot imagine doing hairspring adjustments without curve tweezers, but I often see „adjusted“ hairsprings in fora with a series of small kinks instead of a curve.

You should practice your skills with an intact hairspring, best of an alarm clock, make determined distortions and try to remove again. And make yourself familiar with the few rules for such adjustments.

I can strongly support these two recommendations based on my own (limited) experience.

Thank you for sharing your tips, Hector. I'll certainly try the slab of glass. Re wrist & finger support, my problem is not so much tremors as involuntary jerks - hence the putting analogy! I also tend to use one pair of tweezers but with an old, very fine oiler. But as I inrimated it's getting the HS to lie in one plane that I find most difficult......

It's definitely practice I'll give you that. Maybe try something a bit bigger so you can see the changes that you make easier. With a small spring like this it's very easy to get fuddled, until you understand how your intentional bends affect it . I like to well fed before I start playing around with a spring, heading towards low blood sugar becomes apparent at magnification. I always use 2 pair of curved tweezers for straightening out twists and vertical bends. I keep my hands low on the bench so that my wrists and forearms are flat down as well. The tweezers are slid between middle and wedding finger, i find this gives me the most stability with zero shake.

I kind of found this tweezer holding position by accident, i was looking to increase the angle of the curve on the tweezers to make the tips more upright, which is really important when correcting a twist. Otherwise a compound bend is created ( a twist at an angle other than 90° ) A really good tip from when i was learning to understand how my bending actions affected a spring; was to use a big spring, even better practice with an old worn mainspring or the central portion of it, it's basically the same thing and will behave in the same way as a hairspring, you need a small one though, it takes a lot to bend a mainspring with tweezers.

Yes: I'd actually realised that the contact angle could have such a complicating effect & am careful to check the angle of the tweezers before gripping the spring. In particular, I rotate the work surface so that the tangent at the point of the spring I intend to hold is pointing along my line of sight: this has helped me to correct/avoid introducing vertical divergence which I find the most annoying issue!

This is going to be my little “things to do when I’ve nothing else to do” projects. And yes, that’s a 5 pence piece!!

I thought I was getting OK at hairspring manipulation until I tried to detangle one on an Omega cal 455 - ladies automatic movement (with sweep second) just 16mm diameter (very small and fiddly movements - best avoided).  The hairspring was just 3.5mm diameter. Even with my sharpest tweezers working under the microscope I had to admit defeat and find a new balance. In the 'flat' I could correct errors, but trying to make vertical twists was beyond me.

  mike your skill  have constantly improved from the start. 

Manipulating tiny coils is just another level of improvement, must say its painstaking. 

When you feel ready to attack the next tiny coil, be confident your dexterity 🧐 is practically on the improve  and you will get proficient at it, and come to give good advice.

Best regards.

    • Looks like a 5150 emulator running JDEdwards.  my desk looks similar
    • As Mark owns this site and is it’s only administrator I would expect that any claimable IP would belong to him. There is obviously some disquiet at the moment because of the lack of response from him about several issues. Rather than go off trying to build ourselves a new site we do have a Facebook group and a discord server so that if this site disappears we can keep in touch and decide what to do about it. Mark pays for this place and I would expect that most of that would be storage/database/backups.   Tom
    • Thanks MariusJacob. It's an option I will consider if the screw size prove to be non-standard. Currently, I am planning to first purchase a digital caliper to precisely measure them. Head diameter is 2 mm, length 2mm as well, but my old caliper is too worn for the thread diameter. It may be 0.9 or 1.0 mm. I keep going ...
    • Hopefully something less precarious and better managed than Facebook,  but that might be a last resort. From what I have read above,  people are concerned about potentially losing the extensive database of reference material such as walkthroughs that they have built here.   A good continuity plan would preserve that.  I don't imagine that a site like Facebook would be capable of hosting such a thing in any practical way. From my experience of it,  it mainly seems to be configured to allow businesses to advertise,  and people to post random photos. I don't think that providing logical access to an organized collection of related data is really part of Facebook's mission statement. The Invision platform that we are on does a good job of that and provides a good search function, thread following and so on.  A question that would immediately arise for continuity planning, of course,  is "who owns the copyright on the Watch Repair Talk database?"
    • The number in the case (1444) is the reference number. On older movements it's a shorter number. When I applied I sent the serial number from the movement and the reference number on the case back. In my case for a 1967 Cal 30L the case number was 7855.
