I have an old movement (my first watch ever actually) that has an EB 8805 caliber. I've tried to service it it and it has some funny (cheap ?) solutions that has me puzzled. I managed to disassemble the balance staff shock system but I have not managed to get it back together and onr shock spring has gotten away, never to be seen again. When browsing around I found similar systems that was in my watch called KIF Trior that actually has special tools that might prevent you from turning mad. So my question is if I'm barking up the right tree here. Are these KIF and would the tools from cousins help me ?

Yes and yes.  It is possible to make your own tool with pegwood, but fraught with frustration.  Also, one can re-seat the Kiff spring in the setting using two sharp tweezers and a fair amount of profanity.  The trick is to seat two lobes of the spring BARELY into the setting and then while holding the spring, gently and carefully work the third lobe into place.  Hard to describe, but not too hard to actually do, but it can also be frustrating.

 

Ask me how I know.

Well I figure to be a beginner for at least 10 more years, but:  rduckwor didn't mention that they turn into position.  Actually they screw in clockwise as though into threads.  Tweezers or a small screwdriver did the trick for me whilst steadying with pegwood.

I bought the kit of tools from Jules Borel, but mainly to get the Kifs....  Found some pinged ones later in the oddest of places!

And another bit of advice learned the hard way.  Save the profanity until you are a minimum 2 meters from the bench.  Saves many heartaches!

The Kiff's can be turned in either direction.  That's the one choice you get to make.  It seems that we are just prejudiced to turning things clockwise.  WHY??

 

The discovery of "pinged" parts is the second law of watchmaking.  You will always find a part you lost when searching for another part you lost.  Unfortunately, you will not remember which movement the found part goes to.

 

The first law is that when holding a part in place with one hand and needing a part to fit, i.e. a bridge, that part will be upside down on your mat.  Attempts to pick this part up and drop it in order to flip it right side up, will ALWAYS result in said part falling and remaining upside down.

 

Murphy was a watchmaker.

They're bi-directional?  Did not know that.  I'll try that next time and I hope next time never comes!

I've managed to find every ping so far but for an ETA2370 spring barrel.  Truth is as messed up as fiction.  Never work around open boxes of radio parts and try and stick to just one hobby in any given region!

Thanks for your help. I ordered the KIF tool set with the extra springs since mine went missing. However, when I sat down yesterday to fix it, the d*mn spring mysteriously reappeared on my workbench. I have no idea were it hid but I suspect it stuck to my dust tray somehow. The tools were smaller than expected but color coded on size so it was not a big problem figuring out what size my spring was. After 10 minutes both upper and lower springs were mounted. The tools was worth every penny. My first watch (40+ years) is now ticking away !

I plan to get me one of them kif trio spring tools, good news to hear you are statisfied with the purchase.        The watch looks like new.

    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
