Hi Everyone!

I am working on this Vulcain which has the regulator (below) and I’m not certain how to regulate it with the two pieces. It was +412 SD then I moved it and now it is slow. See below time grapher. If I move one and try to move the other the BE goes up.

 

Any direction would be appreciated.

 

Thanks to everyone in advance!

Not certain you can see the regulator in this photo very well.

You do not have 2 regulators. The upper one is the stud holder, once set correctly it need not be moved unless the balance needs to come apart.

The lower one is the regulator which is used to adjust for fast/slow. This has only a limited range up to around 10 mins/day . If your watch has more error than the problem is elsewhere.

There seems to be something on the hairpsring just before the regulator?

As @anilv says the lower regulator is to far adjusted to the right. If you look from the upperside. The brass think on the time regulator should be there. Set the beat error by moving the upper arm. Sometimes the time adjusting arm comes along when you move the beat error arm.

You all ROCK! About as good as I can get it for now. A piece of fuzz I have to remove from the hairspring but I don’t think it is going to get any better!
Thank you for all the help!

    • Yes, what I wanted to say is that the cock is part of the main plate, manufactured together with it and not meant to be interchangeable. Even if the other cock gets in place, it is not sure that the balance then will stay upright. You should use the original cock when it exists and is not destroyed. The adjustment needed by bending it is not irreversible. It is minimal deforming that is needed. No tools are needed. I have pointed to all needed references here for the balance staff endshake checking and correctness confirmation. The only tool needed for the correction is You thumb. The cock must be fixed on the main plate, no need of special plate with holes and so on. If You will feel more confident, then measure with Vernier caliper the height of the top of the cock where the stones are against the main plate bottom when the shim is fitted and try to reach the same height when bending the cock (with no balance in place!!!) Caliper with screw for fixing is perfect.    
    • Thanks for the reply. I polished the head of the screw using 1500 to 10000 lapping paper and a screw polisher. This is why I think the head blued and the rest of the screw didn't. Silly question, how do you polish the whole screw inc threads, if that's what it needs to blue? 100% clean, Elna red and heated ultrasonic bath + IPA rinse. Finally, there is definitely heat leak as there's about a 30c difference between the brass bed and the soldering station temp. Having said that, the bed temp was stable. I will try to search out a better brass pot, but I haven't found one yet, hence the stainless steel bowl. 
    • Agreed but that's where WD40 excels, water displacement. 
    • I would change the container to a thick walled brass one to start with. Looking at you screw pictures they don’t look shiny enough, really it’s best to do a black polish on them before trying. Also make sure once polished they are scrupulously clean, I dunk my experiments in acetone before bluing.   i think the thin walled stainless container to leach away the heat from the shavings, most successful bluing videos for example use thick walled brass to hold a good deep amount of shavings which acts as a better holder of heat.   Tom
