I've recently acquired my ETA 6497-1 movement after completing Mark's first 3 modules.  I felt empowered, but underestimated my limitations.  I've been reading everything I can , including on this forum, and some books, i.e. DeCarle's, etc.  I was anticipating a kif type spring, but discovered the spring holding down the cap stones are of the Novodiac variety.  I foolishly attempted to remove one without the requisite experience, and pinged it.  It's gone.  Otto Frei's website says it's a few weeks for delivery.  I was going to order their assortment of 5 incabloc settings on which to practice disassembling, oiling the endstones, observing the bubble, etc. 

I found a video on removal/replacemnent of the Novodiac spring/incabloc ass'y.  I've turned down a piece of brass rod to 1.4 mm, and roughed up the end to use as a tool to assist.  It seems the method is to get one "section" of the three under the ways, rotate, repeat, and voila.  I feel I can do it now, but don't have a spring. 

I'm humbly asking if anyone has perhaps a small supply of Novodiac springs, might I please buy one from you?  I'd like to get the movement back together, but the pandemic has deliveries delayed for a better part of a month.  If so, feel free to PM me. 

If so, I'd be very appreciative, I'd pay postage, and whatever price you desire.  Thank you all.

I don't have a spring, but I want to share my cap-jewel technique: I place the watch in a plastic bag that I get from a grocery store—you know, the very thin bags that we get shopping. I place the watch inside a bag while removing delicate parts and when things fly it is almost certain to be in the bag. It is inconvenient but it works. Looking down into the bag and working is really kind of crazy, but I know my limitations and it is a trick that works for me. Good luck! 

Regards.

Thank you kindly, David.  Perhaps I'll use a Publix bag until I get my holding pressure on the tweezers second-nature.

I leaerned to send a strong magnet to recover the spring as the luxury of ordering spares is unavailable to me. I I don,t have a scrap of the same caliber but many other makes which might interchange. Members can chip in info to produce such list of interchangables on this thread and the like, for all members and non members to enjoy.

Thank you, Nucejoe, but alas the spring is brass.  I really must get myself a proper workbench.  I'm using the kitchen table with a white bedsheet cover.  It's not high enough.  I've been doing all my work on a 4x8" work surface.  I put my staking set box on the table, set the jeweling set box on top of that, and work on the JKA box.  It's a good height, but the size of the surface is more trouble than it's worth.

JohnR725; that's very kind of you to provide a cross reference.  For those in the know, it seems since the incabloc setting on the balance cock is different than the one on the dial side?  They're different part numbers.  Are the end stones the same size?  I have about a dozen orphaned movements from when I was early on, and popped out many of the jewels.  Seems the end stones on the 6497-1 are a good bit smaller in diameter than the other end stones I have accumulated.

Usually the spring is gold plated steel.

Well that changes things!  I have a knife rack that's in the garage.  I'm about to hover it about my kitchen floor.  Thank you!

No luck.  Thanks for the suggestion, all the same.

Every time I'm on the floor looking for a part I hear the same song. . .

"You will start out standing
Proud to steal her anything she sees
You will start out standing
Proud to steal her anything she sees
But you'll wind up peeking through her keyhole
Down upon your knees" 

--Bob Dylan.

    • Hello Tom and welcome to the forum.
    • Hah! Well, California will have to do. Lived in TX for a brief period back in the early 70s, though, so maybe that counts. 🙂 Funny you should mention making vacuum tubes- I've actually tinkered with that! It's REALLY tough to do, and I've never made one more complicated than a simple diode that barely worked, but I have played around at it. But there's just no infrastructure for vacuum tube fabrication. I can get a lathe and learn how to use it to make complex parts, and while it might take a while to learn- and money to get the equipment, of course- it is possible to do more or less "off the shelf". But vacuum tubes, not so much. There are a few folks out there doing some crazy cool work with bespoke tubes, but they have setups that are far beyond what I can manage in my environment and it's mostly stuff they built by hand. I also have been playing with making piezoelectric Rochelle Salt crystals to replace ancient vacuum tube turntable needles- nobody's made those commercially for probably 60 years. I'm a sucker for learning how to do weird things no one does any more so I can make things no one uses work again. (I think this is drifting off the topic of lathes, lol).
    • You shoulda been born in Texas. Tough to make a vacuum tube though. You can substitute with a MOSFET eq ckt I guess. I was playing around making a pinion the other day. More to it than meets the eye.
    • Well, turns out it was a fake bezel! The crystal is domed mineral glass and I was able to find a cheap replacement that should be here in two days.  I used my crappy little press to pop out the cracked crystal, Ill give the case a good cleaning in the meantime and do a once over on the movement.
