Rolexman Posted October 18, 2009 Report Share Posted October 18, 2009 It is from an old pocket watch (remontoir). Because the staff is broken I would like to replace it. I found this on-line tutorial but I'm still not sure how to go about. Any tips or suggestions are very welcome!

FxrAndy Posted October 18, 2009 Report Share Posted October 18, 2009 My best suggestion would be to get a copy of Henry B fried's book, "The watch repairers manual", part 7 pages 97 to 128, in there it lists every thing you would need to know, but you would need some specialists tools like a lathe and staking kits. The book is worth every penny, If i was going to be around next week i would copy it and post it over but i will be away from the office unfortunatly Link to comment Share on other sites More sharing options...

And being form Europe and not owning a credit card it is almost impossible to order Link to comment Share on other sites More sharing options...

RWG Technical Posted October 18, 2009 Report Share Posted October 18, 2009 What tooling to use will depend on if the staff is riveted or press fitted. If its' rivited (most are) then you need a lathe to cut the rivet off. Then you need a staking set to remove and re-install the staff, of course you need a new staff. As well, where is the collet and hairspring and roller table, do you have these parts, if they are missing you won't probably find a replacement one. The reference given is much better than anything I could type. If you haven't replaced a staff before, buy 2 of them, because you'll most likely break the first one you install... Example of one I just did on an Elgin... Link to comment Share on other sites More sharing options...
Rolexman Posted October 19, 2009 Author Report Share Posted October 19, 2009 Thanks for the info Zig, great pics by the way. It looks really difficult. But then again in my early years I found removing a stem difficult I have all the parts complete and I already gave he movment a complete service. In the end I noticed the balance was touching the escape wheel bridge and the thus the movement didn't run. No idea how this happened but I tried to gently push the balance and make way... SNAP..NOT. So that's the storry. I regularly buy new and more spcialized watch tools but I still don't have a staking set or a lathe . They look expensive so maybe I'll ad them to my x-mas list Thanks again for the input. Appreciate it! Link to comment Share on other sites More sharing options...
RWG Technical Posted October 19, 2009 Report Share Posted October 19, 2009 You're welcome. The lathe and all the accessories that you need are going to be in the thousands of $$$ and the staking set can be bought used for a few hundred dollars. The problem with the lathe is the amount of practice needed to be able to use it, or even sharpen a graver correctly so that it cuts. Your best value is to find someone locally who can replace the staff for you. Link to comment Share on other sites More sharing options...
Toadtorrent Posted October 19, 2009 Report Share Posted October 19, 2009 Me being horolgically clueless, I have no idea what you were doing in the pics Zig...but I just loove looking at the pics. How big is that lathe? It looks smaller than a stapler! I've never seen a jeweller's lathe in person before. Link to comment Share on other sites More sharing options...
RWG Technical Posted October 19, 2009 Report Share Posted October 19, 2009 I like the pics as well, seems to always look more interesting and impressive in pictures... The lathe is quite small, the bed is about 14" long, and the stand it sits on is about 14X18", the motor you see is about 8" high. Collets (the thing that holds the parts in the rotating head) start at 0.10mm with one every tenth of a mm, up to 5.00mm, I don't have much use for anything much larger than this. Unlike a machinest lathe, there is no cross slide, the cutting tools (gravers) are held free hand on a tool rest, similar to what you would do on a wood lathe, although at a much smaller scale.

Neuuubeh Posted October 28, 2009 Report Share Posted October 28, 2009 Heh that pretty much kills my hopes to replace a staff on a 21jeweled Burlington movement on my own Link to comment Share on other sites More sharing options...
