Can you use a staking set only to repair a balance staff?


Recommended Posts

So once you remove the roller jewel, you can use a staking set just fine. It's very hard to describe in text, but you will want to make sure the balance staff is going through the tightest hole it will fit, so the balance wheel doesn't bend. Then you punch it out. It's obviously not the best, and can cause the balance wheel to warp slightly, but it definitely works.

I've looked at the stakes and I cant see a roller removal tool. You can get one of these its not expensive and are very easy to use. Mark has the same set as you you could contact him and get his advice.

It says it removes friction fit staffs. What about rivet?

I'm not sure if it's a friction or rivet yet, but I am assuming it is friction since it is older.

 The roller jewel has broken you are correct on that, it is also fitted the right way. Going back to a previous post this staff will be riveted. As it's an American watch you should be able to find the parts, you have the make and serial number so when trying to obtain the parts quote both. You could fit the roller jewel yourself if you have ones in stock, fitting is quite easy, but you need the right part and the right tools.

 

Its a good movement.

It looks like the roller jewel is broken or upside down? Does double roller mean it has two jewels or is the roller plate upside down?

I don't want to spend much time on it if the jewel is broken. How do I find the movement on eBay?

The part with the impulse pin serves only one function-to deliver the impulse to the balance wheel. Similarly, the lower roller-called the safety roller-serves only to keep the pallet fork from moving when it shouldn't. There is only one jewel and it looks worn or broke and sticking up through roller, possible last repair jewel was longer? IMO you are better off having repaired (or repairing yourself), then try to find similar movement with good part. You might buy a watch that has same issue and pay top dollar for it. Even though it's a 19 jewel, (btw jeweled winding gear/ motor barrel is unique!) Very nice and worthy of your effort.

I swear I could make a living doing just roller jewels and balance staffs.

Hope that helps.

It may just be a reflection but it looks to me as though the impulse jewel is poking out the bottom of the table as much, if not further than the top. Could it be that the shellac has failed allowing the jewel to slip? In which case it would just need the roller table removing, the jewel correctly repositioning,and some fresh shellac to hold it in place.

The jewel is sticking out the top and the bottom it is barely there. But the problem still persists of which tool to use for the balance staff. All I have is the 5285d Bergeron staking set and need to know which tool to add to it to properly remove the roller and plate. Old hippy suggested a tool, but the tool is for friction. Idk if I can still use it for riveted balances?

    • I used to just remove the stem pop the movement in its case then put the stem back in check everything then back on the timer. 
    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean. Something like this, but tbh its better to just learn to do with your fingers.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
