Hi all,

I have an EB 8800 on the bench and the third wheel has broken.

I see from the service sheet that this piece comes in two flavors.

But I don't know which one I need.  Cousins have them both in stock and listed as...

Third Wheel ( 210 ), EB 8800

Third Wheel, Upper Conical Pivot ( 217 ), EB 8800

 

Any ideas how I could find out?  I would hazard a guess that I need 217 as the remaining pivot I can see has a conical end?

 

Many thanks,

Ash.

Yeah, I thought the pivot was broken, it looks a bit short.  I will use this broken part to practice on.  Not to derail my original question, but by peen do you mean hit it with a staking set to close the hole a little?  If so, which stake would you use?

The hole looks shagged to me and will likely turn untrue if just closed with a stake. 
 

I think you may need the cone bearing type as it’s unjewelled - check the remaining original pivot to confirm the profile of the tip.

      Any tips to correct a sloppy error?

      Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      By Neverenoughwatches · Posted

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.
