6498 Hairspring - Can It Be Saved?


BlakeL

Recommended Posts

I got lucky and was able to find somebody locally selling a #18 K&D set.  It's about an hour and a half away but is a very good price and doesn't look to be missing very many parts.  The picture is not great but it does look as if some of the parts have rust but hopefully will clean up fine.  I'll be picking it up next Sunday.

I got back to working on the 6498 last night.  Fixing hairsprings is so delicate I find myself correcting the bends/twists then right after making it much worse. I was able to fix one of the worst twists but now I have a very slight downward bend towards the end that you can't really see and at some point when trying to grab the spring I bent the inner bronze ring so that if I mount it does not lay perpendicular.  It might have been like this from the beginning but I have a feeling it was me.  Any suggestions?

I struggle with hairsprings although better than I was. I found the last time I wanted to bend up a touch I put the hairspring on a staking tool & put it where I wanted to bend over a hole and pushed VERY GENTLY with some Dumont 5 tweezers and it worked.

Good idea, I might have to try that since I have a staking set now.  It should be pretty easy to finish off the end but that bend in the inner ring scares me but I'll have to try since a replacement won't be cheap if I can even find one.

Like I said me and hairsprings just don,t get on.  But this method worked but you have to be very gentle with it.

I see a vid where a guy was making a hairspring overcoil and he pushed the hairspring into a tube that he had made which is the same principle.

I spent some more time with this over the weekend and I've given up for now to save my sanity. I'll keep this movement for parts and come back to it later when I have some more experience and a better 10x loupe. I found another cheap 6498 pocket watch on eBay for around $50 that is working. It does have some rust on the ratchet wheel but i can swap that out.

    • This set lever seems to working ok unhardened Nickelsilver, might it deform if i leave it that way ?
    • I found this from a while back CS100 seems fine, but at around 500 Vickers it's not quite as hard as "blue" steel, but still harder than annealed. I'd try to find annealed (the post above has a U.K. supplier of small quantities).
    • As an experiment i was thinking of not hardening it to see how it fairs. Now that i have a complete template i could knock up another in half the time if this loses its elasticity. I might play about with a few pieces today to test their bending and spring properties. This was cs 100 the supplier quoted in annealed state, it was nice to work with files so I'm taking it thats its state. What you are looking seems like it would need annealing to work it. This is why i went for this stuff that cuts out that process, it was so easy to work.
    • Showing state of hairspring on receipt, backplate & 'dished' wheel.  Thanks, Nev. Amplitude v. weak - balance wheel turns over arc of only ~20deg. Don't know how to calculate movement rate or safely vibrate balance spring! Meantime I have reduced the 'dishing' & clock no longer runs for more than a few minutes except face down which supports my theory that it was 'dished' as a hack to avoid doing a proper repair.
    • I would harden and temper (to a light blue). It's so easy to do and only takes a couple of minutes. A search on ebay UK for "spring steel strip cs" finds plenty available in small quantites and thicknesses from 0.1mm up.  But the question is ( @nickelsilver) which "CS" number is best for watch parts ?  Also, from one of the ads : "CARBON SPRING STEEL. SIZE IS METRIC 15.00mm X 0.10mm X 304 MM  CS100 FINISH BRIGHT . HARDENED AND TEMPERD TO 480-530VPN" I've no idea about 480-530VPN. Does that mean it needs annealing before working?       Have you seen this video, he shows how to determine where the indents go ?
