  1. The balance wheel is not attached. I'm just cleaning the hairspring since I'm sure it picked up some gunk along the way. Sent from my iPhone using Tapatalk
  2. Hot glue probably would have worked a charm, actually. I used a Devcon epoxy with 60m working time, applied with the tip of a sharpened x-acto blade. I don't have spare oilers like all you old timers . I'm brand new to this hobby so I don't have spares of anything! The epoxy seems to have worked fine. And by some grace of His Noodly Appendage, the hairspring collet sits nearly perfectly centered over the pivot hole on the balance cock even after all it's been through. I'm going to remove it one last time, give it a rinse in naphtha and denatured alcohol, and put it all back together. Sent from my iPhone using Tapatalk
  3. Thank you Mark! Any particular brand or type of epoxy you'd suggest, or can I use any slow drying epoxy made for metals? Sent from my iPhone using Tapatalk
  4. I honestly have no idea if I can do that or not. I don't know the first thing about how to use those pins or if they'd work with the etachron stud.
  5. While disassembling a Unitas 6497 (or during subsequent reassembly) I slightly deformed the hairspring, and to fix it I removed the wheel from the balance cock and then the hairspring from the wheel. The balance cock is of the Etachron type, so the index pin is simply clipped into the stud support. The spring sits inside a notch on the underside of the pin, and is secured in place with some sort of gummy, flexible adhesive (instead of a tiny pin, as I've seen elsewhere). Anyway, I had a lot of trouble getting the spring stud back into the stud support, and after about an hour of man-handling the glue finally gave out and the spring came loose. Now I have a spring (in perfect condition, thank you very much!) and stud I need to reattach to each other. What kind of adhesive is this? What are some accepted ways of reattaching the spring? I saw someone on the internet use shellac, but 1) I don't think that was the correct thing to do (this stuff was flexible, and probably for a reason) and 2) I don't have shellac or know how to use it regardless. Thanks for reading, and thanks for any help you can offer! Here are some pictures to help visualize what I'm talking about:
  6. For more context, here is a picture of the hairspring removed from the balance wheel, and a couple of its stud. I'd prefer not to buy a new assembly, as it costs almost as much as a new movement! [emoji23] I can see an obvious kink in the end which should be pretty easy to remove. I just have no clue how to reattach the bugger. Sent from my iPhone using Tapatalk
  7. That picture is really helpful. I did get the spring removed and I believe I got the right curve (or close to it), but when I tried to reattach it to the cock, the spring came loose from the index pin. How can I re-seat the spring into the pin? It appears to sit in the slot and it's secured by some soft adhesive. Will I need to clean it and reglue it, or can I reuse the pin as is? I had a really hard time getting the pin to clip back in. Took me about for hours of fiddling with it before it finally came loose and I put it away for a day or two...

  8. I am working on a Chinese 6497 clone that I bought so I could follow along with Mark's videos (and also enrolled in the TZ Watch School). Disassembly went fine, but on reassembly I noticed that the hairspring was bunched up on one side. I adjusted the index pin, but the bunching was much more severe than it could compensate for. So, clearly I've bungled something up along the way. The spring itself does not appear to be damaged. When I invert the balance cock on the table the spring is concentric, but the wheel isn't centered. Thus, when the wheel is centered, it deforms the spring. I thought I might need to follow Mark's video regarding hairspring alignment, but not much of it applies here (I think?). However, it did highlight the fact that I have no idea how to remove the spring from the cock, because it is attached much differently from his video. I've attached the best pictures I could get. So, a few questions: How do I remove the spring from the cock? Can I simply slide the pins out? How do I disengage the spring from the regulator pin? Do I even NEED to remove it, or is this something I can fix with parts in situ? What are the best resources for learning how to realign and center the balance wheel collet? Why might this have happened? I was pretty careful with disassembly, so it would be nice to know what I did wrong so I don't do it again next time. Any help is much appreciated.
