Which EB 8800 part?

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.

    • In the meantime whilst awaiting a better plan, please drop me a quick hello on my email. 
    • I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .
    • I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark
    • That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much. 
    • Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
