Hi, so I've noticed that there are 3 types of balance cap jewels for oiling the endstones..

 

Picture included of the 3 types.

 

The first one is the most easiest to open, and the second is also fairly straight forward as well.

 

However does anyone know if the third one is able to be removed?

 

It has baffled me and I'm not even sure if it's meant to be removed, so was wondering if anyone else any experience with this type?

:) Novodiac? Try a diafix from Seiko!

I have no problem removing them.

 

If I ever find them once they are out, they are a bear to get back in place. If I magnify enough to see them, they make all my tools look ginormous.

The second & third style unless they are really gummed up I do not remove the jewels. I clean in my L&R watch cleaning machine after giving them a really good soak in one dip. Then I use an auto oiler to lube the jewels.

Oh that's interesting, that would avoid any risk to the hairspring.

 

What one dip solution do you use?

The third is easy, you have two screws under the balance cock, you need to disassemble the cock from the balance to access the screws.

 

For the second (jewel in setting with cap jewel, your picture show a chaton setting but in general the cap jewel is flat and no so easy to remove)  its depend how easily the cap jewel comes once you have remove the screws. My best option if the cap jewel don't come is to used a stacking set and push the jewels from the back. You have to be careful when selecting the punch and used very light force; the punch must push the setting, not the jewel, use a flat or concave punch, no hammer just tap with your finger or a the back of your tweezers. This is the same process if you need to change a broken balance jewel in setting.

 

An other quick and dirty but safe option is to oil from the jewel hole using an automatic oiler, the oil must not spread on the jewel face.

How do you remove Rodico from a cap jewel and Novodiac spring after they are replaced? I was told to use it to put the parts in place but now I have it where I don't want it.

Thank you for your help.

Been there done that. I think you have to remove it again and clean with some solvent. I think naptha works. Sometimes Rodico isn't the best to use? Maybe some clean Rodico could remove it? You will have to try?

I haven't heard of any... I don't think there is one. I use a pair of tweezers and a pin made from a broken oiler sharpened to 0.2mm like in the video below (thanks again perplxr for the tip :) )... and lots of prayers, sweaty palms and searching the net for movement donors :))

 

 

p.s. the video doesn't present a diafix but only the pin ;)

I stand by the rodico method. I take the endstone with the rodico and oil it under 10x, put it over the other jewel and use a tweezer to make it sit in its place while pulling off the rodico. The risk of the endstone flying is almoast 0.

      Thanks Hector, I do think though that the problem I am experiencing is specific to Miyota movement in general and the 6T series in particular.  When you describe putting the bridge you are talking about the train wheels.  The problem here is that under that same bridge you have the 4 train wheel, the barrel, 2 extra winding related wheels and the center sweep pinion.  I can mostly put them in their holes but 2 of those (the 4th wheel and the second pinion are completely under the plate so I can't nudge them in the right position.   I managed it with a larger Miyota 8200 series but with the smaller 6T15 it is even worse. Anyway, I'll retry tomorrow evening or this week end.  This evening is going another rock climbing day (going from very light pressure on tweezers to much more force going through the fingers, although in climbing we also want to use the absolute minimum grip which won't make us fall to save the muscle and be able to climb longer routes). to add insults to injury, if you read this thread from the start, I initially messed up the disassembly as I couldn't detach the rotor.  I normally (and I think I did this time too) put all my parts in their individual compartments in the part tray and I am doing my best to be very careful about them.  But in the week and a half it took to figure out how to detach the rotor I somehow lost the screws from the bridge.  I have a few others which will be needed later.  I know they are reference 922-600 but I couldn't find what it means in general term so I don't know if I can buy replacements or an assortment of screws and replace those 2 by others.

      How to deal with shock setting

      By Neverenoughwatches · Posted

      Something that can happen with a lyre spring, the back of the arms can bind against the shoulders of the chaton cut out where the spring is fixed in when the spring is lifted out of the way. To stop the spring bending or breaking it needs pulling forward slightly before lifting so it clears the edge of the chaton.

      One way is to file it by hand. Good file with sharp edge is needed. Another way is with the aid of milling attachment. There is one more way, thyat is really only on the lathe, but the arbor has to be attached perpendicular to the axis of the spindle. Will be easier to show pictures than to explain this. I must say 'Good night' as my wife is now awake and is roaring when I get closer to the computer...
