Could someone advise me if this is broken? I can't see to get the wheel to fit (in the bottom jewel or in the bridge, my movement has a bridge purely for the escape wheel)  and when I do get some sort of fit, it's loose and never really bites the second wheel unless at an angle. When I was stripping the movement, I made a huge rookie mistake and the wheels feel out, so I didn't get a good look at how they were all connected (now I am in a world of pain lol).

If I have broken this wheel then it would explain a lot. ST36 movement.

Thanks guys

hopefully I will be able to contribute and not just ask question further down the line. ?

Sorry to say yes you have, both pivots are missing. 

Thank you for confirming. 

I am OK with this though becauseI have learnt some good things here! I identified that this could have been my issue (it was), need to work on being even more gentle and now I know what not to do (although I can't promise I won't do it again). 

I guess seeing as this was my only movement, I need to get a new one? or are parts for these Chinese movements readily available?

If that fell out, and wasn't forced out, it seems the pivots were already broken before you disassembled it.

If you "ripped" the wheel from the stones, it is possible to break them. Check the stones to see if the remains of the pivots are still in there, and remove if they are. Unusual to see BOTH pivots broken off...

This is definitely broken on both ends due to me most probably being to heavy handed and not giving the respect need. Definitely can take a lot from what happened here, as I mentioned above. 
 

I appreciate you all confirming tho.

ST96 are not chinese movements unless this is a copy? I have seen some ST96 where the finishing is very poor but they were still swiss.

Anilv

Isn't ST96 made in India now? 

OP's is ST36.  How does it compare to the Swiss made? haven't seen one upclose.

You sure have ?.

If that is any consolation so have the rest of us.?

What helps break more, is dried oil that tends to keep the pivot stay put, you then wrestle with and break it. 

Perhaps a pre- wash of mainplate+ gears+gear bridge prior to disassembly helps  pivots get unstuck.

It looks to me like you need something truly affordable to practice the basic skills. I'd definitely recommend you pick up a lot of used Vostok calibre 2409 or calibre 2414 movements. These movements are likely some of the most affordable on the planet and will, in my opinion and experience, give you 80 % or more of what a Swiss movement will for a fraction of the cost, and you'll always have spare parts for next to nothing. Here is my service walk-through and ode to the Vostok 2409 calibre if you'd find this to be an option.

Thanks for the advice and link to your service walkthrough. Very useful indeed and now my afternoon is going to be looking into Vostok calibre's.

      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.
