Automatic mainspring

Hi

Guys

I have asked this before so i am sorry, but i have put a pic up the best i can gedo,hoping someone can explain it to me so i understand.

Below is a mainspring. The one i have numbered number 1 is what i call the mainspring and the number 2 is the bit added on so it catches and does not over wind.

My understanding is that number 2 goes against the wall of the barrel?

In most cases i have seen it has to, so the arbour catches the spring.Plus it tends to want to bend that way

 

But if i put the number 2 piece against the barrel wall of the arbour it cannot be configured to catch the spring in the middle. I have tried every differnt way you can imagine left turning, right turning, arbour up, arbour down and it don't work.

If i put it in so the arbour and spring are correct either the number 2 piece sticks out or worse still it snaps off.IMG_20201118_150526.thumb.jpg.b4ff73f3f33fe59677f1fc2dd210b777.jpgI know its not ideal winding a spring by hand but you do what you have to do with what you have. I have had this problem on nearly every spring i have tried to insert. Know problem when it comes pre wound. So can someone explain this to me and tell me how i shouild do it or what i am doing wrong.

cheers

The click shows you which direction( clock or anticlcok)  ratchet wheel therefore the arbour should turn to wind.

Examine the arbour to see which end goes in the barrel and which into the cover hole, thereby direction arbour hook should sit( clock/ anticlock) is found.

Mainspring should go in so to catch the hook.

The part you numbered 2 is called spindle.

Good luck.

    • Sounds great! And yes, I would use grease for the keyless as well although treating the parts with epilame would make the grease less likely to spread in the long run. Not critical but won’t hurt. My current strategy is to epilame treat all parts getting in contact with oil or grease.
    • Hello everyone, for what it's worth, here is my approach: 1. Escape wheel submerged in Epilame, then dried quickly with a hairdryer. Then the final tip of the pivots are cleaned by poking into pithwood. The logic being that the Epilame is removed at the intended contact point (to avoid any residue that may mix with the oil), but remains in the areas where oil is not supposed to spread to (further down the pivot towards the wheel). The escape wheel teeth also benefit from having Epilame to keep the 9415 in place.  2. I use a syringe to treat only the pallet stones. I suspend the pallet fork with some Rodico so that the stones hang downwards. I notably use a rather thick needle where a drop WON'T form, but rather where the Epilame liquid stays in the needle tip, which I then dip into the pallet stones. It requires some practice to get the right amount of Epilame into the needle tip, but it works for me now. This way, no drop will "jump" onto the pallet fork and potentially go all the way to the pivots.  3. I let the movement run for a few minutes without lubricating the pallet stones... to scrape off the Epilame in the intended contact "channel". Then I remove the balance again and lubricate the exit pallet stone with 3-4 successive drops. See the "channel" that forms on the pallet stone in the picture -- not so easy to see, but it's visible.       I am conflicted about the use of Epliame in balance jewel settings. My impression is that the two jewels sufficiently suspend the oil (even 9010). Apparently Rolex recommends NOT to use Epliame there (heard from a former Rolex service center watchmaker), as it could cause additional wear. Apart from that, I follow specific instructions where I can find them. E.g. the infamous Rolex reverser wheels or sometimes (parts of) the seconds wheel. Exception: I'm currently servicing an Eta 2824 and will probably ignore the service sheet that recommends treating the whole keyless works with Epilame and then using HP1300... I'll skip the Epilame and use 9504 grease.        
    • I'm going to give this a try today/tomorrow on my UTC33/Seiko 66, thanks!
    • Hello and welcome from Leeds, England. 
    • Don't forget Mark is a hard working watch maker so he is also tied up with work. I'm sure he is keeping his eye on this forum making sure it is running along nicely.
