I don't recall what you're working on, so accept my comments knowing that there will be individuals here who absolutely could/would attempt to fix that hairspring.

I assume that when you say:

...you are in fact removing/replacing a worn or broken balance staff with one that wasn't originally part of the balance of this particular watch. Depending on the movement, I would have opted to try to find a "balance complete" (cock, hairspring, balance) to replace the whole thing.

If this is your first service (and perhaps your only service) it seems that you're doing a rather deep dive for a beginner.

Did your watch work before you started? If so there is no reason to think that using the pictured hairspring won't continue to "work".

If your watch was having trouble before you began your service there are aspects of the pictured hairspring that would lead one to think replacement would be a good idea.

I'm not that far along so I would have tended towards trying to find an entire balance that would have a good staff and hairspring - I'm not yet comfortable with disassembly of a balance and replacement of parts and the subsequent adjustments needed to get it back in good poise and running order.

Unfortunately I couldn’t find a balance complete. It’s an AS1203 (Ralco).

The staff is broken blocking the movement of the wheel. Confirmed after inspection on microsc.

 

Trying to work on it. It’s a very old movement. The project is a complete review of the lessons of Mark. The hairspring repair is by my own attempt

your hairspring does look like it desperately needs help. If you believe the book I have on fixing hairsprings the cone shaped isn't that hard to fix the rest of it would be depends on how much practice you have somebody that's really good could probably fix all of this.

oh one of the problems with a book like this is the person who's doing all of this is extremely good as this means if you haven't been practicing on hairsprings and practicing means practicing learning how to fix them not practicing on how to destroy them then your success will vary by quite a bit

Or if I just continue using it, the balance is going to work ?

then no it is not going to work at all. The easy way to find that out is after replace the balance staff put it in the watch and see what happens it should become apparent really fast it is not going to work at all.

Hi everyone!

I am proceeding thr replacement of balance staff and saw this hairspring situation.

Clearly not in good shape, but anyone knows if this can be fixed? Or if I just continue using it, the balance is going to work ?

Oh dear it looks like a miniature steel tornado, I'm expecting go see a very small pair of red glittery shoes to come flying out Dorothy 🙄. Have fun in the world of hairspring manipulation.  Good luck matey.

      Part swapper to part maker

      By Jon · Posted

      I would use some binding wire around the part before heating it. It protects the steel from being burned. I know that sounds strange, as you're going to heat it with a blowtorch, but if a part is thin and delicate the steel can literally burn away before your eyes, which isn't funny if you've put hours into the job. I bought some tools steel from Cousins a few years ago which turned out not to be tool steel, because it couldn't be hardened or tempered. I wasn't impressed, as I had spent two hours making the part for it to be useless.

      Questions about my Bravingtons Renown Mantel Clock

      By watchweasol · Posted

      Hi that’s what was meant by animal glue “ a glue made from animal products”. Ie bone , skin and other animal residues.  There was a place at Huntington YORK who used to boil down the ingredients. It stunk.   We used it in pellet form in a sort of Bain Marie on a gas ring  it was very good, didn’t think it was around any more with the modern glues,

      Balance cock stud screw

      By Zedster · Posted

      It's back to the drawing board I'm afraid. As pointed out, the Rodico trick is so fiddly and my pin vice jaws don't close in union. I tried but the screw is so small it's hard to grip the screw in the Rodico without it moving all over the place while trying to get it in the vice. I started to shake too much so gave up before the screw flew off somewhere never to be found again.  I'm now thinking that maybe I could bond the screw on the end of a bit of peg wood and then dissolve the adhesive afterward.  I just had another thought🤔 I have some really small PCB drill bits maybe I could drill a small hole in peg wood and push the screw in, as stated I only need to get the screw started.  Another idea 🤣 Magnetize the screwdriver to hold the screw 🤔

      Generic screws for unknown movements

      Yeah there is a spring under there. Hopefully now I can source a screw for the click and the bridges! Thanks for your help!

      Identifying watch for possible radioactive concern

      By rjenkinsgb · Posted

      Definitely worthwhile, if you are working with old watches - just be sure it's an actual Geiger counter, not one of the vast range of scam/fake "Radiation detectors" on ebay & amazon etc. that detect RF or static electricity...   In the mean time, I'd put the dial and hands in zip bags & wipe down the work area with a damp cloth to pick up any dust, then discard the cloth. The emitted radiation from radium lume is not normally harmful - but inhaling or ingesting a single particle of the material can cause serious long term harm, so do take care with it.
