....onto the question about the pinion ... these are pictures which as I say above suggests its a taper pin/arbor arrangement to my novice eye? is there a tutorial/lesson anywhere on removal and refitting?

Also this is a photo of the banking pins ... the one on the right is noticeably splayed?!! is this correct .... and if not how can it have happened?

The banking pins have been bent to overcome a problem the previous repairer had do not straighten them up just leave as is untill the watch is running  then see how it goes, straigtening them now may give you problems later.

Good work dear Homes. Elementary, when you have eliminated  the impossible, whatever remains however improbable must then be possible as you often tell me. Ahem. Also a monster magnet and a million candle lume flashlight is very handy. I now need a the light thanks

Would that fix have been made to solve more than one  issue ?

Possible ,but it is guessing why it was done. Thats why its best to service the watch and check out the results. If it operates within its parmeters leave it alone if not investigate.

I was silly enough to almost start thinking it was the constant  tap of the pallet fork that bent them. But then decided that was impossible .

I was wondering if there is any detrimental effect to the watch having an out of beat balance. I've only ever got zero.zero once. Effecting time  is not that much of an issue, if a watch is as much 30 seconds out that's only 3.5 minutes a week, not many peoples schedule is that tight. And a once a week adjustment is no great shake. And a lot I assume will forget to wind their watch at least once a week anyway so there will be some time setting going on during that week. Would big errors cause an abnormal  wear on the balance pivot possibly

Hi  An out of beat watch,  depends on the error too far out and the watch will stop the further away from 0 will eventually affect the rate. Thats why when regulating a watch get the beat as near perfect as possinle then start the regultion.

Am I right that this is a pin and arbor arrangement?

What is the process for refitting once disassembled bearing in mind that I do not yet have a staking set.

As the lift angle is calculated from the balance swing it may have a direct inpact the site below explains the lift angle

The closer the beat the easier the watch starts from a standstill. Some I have need a gentle rotation to get them moving and stop too soon before the power has drained

Would bending the banking pins because Heath Robinson way of freeing up a locked impulse jewel ?

But affect the escapement release in the process, while trying find a compromise between the two ?

The bankings pretty certainly didn't leave the factory like that. The escapement would need to be checked to find out why the entry banking is so bent. A guess from afar: the exit stone has been replaced with a stone too long or moved out for some reason, which means the escapement wouldn't fully escape from the exit side as the fork was against the banking on the entry side. Moving the entry banking pin will allow it to escape, but now in addition to the extra lock on the exit side from the jewel being out too far, there is additional drop and total lock on the entry side. The watch probably runs, but amplitude will suffer very much.

 

I've been trying to find a clear description of the steps to checking and adjusting the lever escapement to share, but so far it's been old confusing texts or nothing. It's not that hard to understand or carry out the adjustments, but without a clear description very daunting. I actually know trained watchmakers from good schools who don't really understand it, so it's not just new/hobby folks who are in the dark. If I have time one of these days maybe I'll put something together. In the repair work I do I probably retouch the escapement on a third of the watches I see- it's an important thing to check and correct.

That would be extremely much appreciated! I'd even be willing to pay for it! Folks, please support this idea by liking @nickelsilver's post above!

no one appears to have noticed my question about the arbor pin arrangement which appears to be how the cannon Pinion is fitted?

I need to remove the centre wheel but only have experience of the standard cannon pinion arrangement.

I have found some threads describing knocking the pin through from the Pinion side releasing the wheel ... but no description so far on how to reassemble? Is the pinion simply pressed back down onto the arbor with tweezers, or is the process more involved?

Thanks for any input. 👍

Yes, knock it out. If the center wheel is jeweled at the bridge you want the bridge off, and support the center wheel in a hole in a bench block, or better, a staking tool when knocking out the pin. If not jeweled you can leave the bridge on, but still support it on a block with a hole to pass the pin. The pin will go down as far as the top of the cannon pinion, which should be plenty to pull off the CP and the pin out the rest of the way from the center wheel.

 

Going back, push in the pin, (this is with bridge on), support the large end of the pin on a block, and press down the cannon pinion. You may need to press quite hard, or use a staking tool with flat faced punch with hole to pass the pin to get the CP seated all the way.

I've seen Mark do the resetting of pallet jewels, it looks a very fiddly guessing game. I assume a lot of practise is needed

If done correctly there's no guessing at all- that's the thing, haha. But like I said, even trained (Swiss) watchmakers I've known approach it as a guessing game. Not all, but still surprising.

    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
    • I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.
    • Get well soon Old Hippy, torn muscles.,  not good
    • Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.
    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
