Ok, I think I will open a can of worms, but here goes:

 

How do you oil the pallet jewels?

 

I know there are several ways to do it. I would be very thankful if some reasoning or pros/cons would be presented. And also, how could one check if they are properly oiled. I think the correct oiling of the pallet jewels is one of the critical things in watch servicing.

 

Thank you,

Bogdan

 

 

 

p.s. I saw Mark's way... don't think it's the only one. I also expect him to have something to say in this topic  :) if he finds the time

So it's pretty straightforward, you just oil the damn thing, right?

 

 

...only once or three times at 5 teeth interval; when it's stopped or in motion, 941 or something else, epilame or not, how do you check you've done it right...

 

 

Come on! Is it a trade secret or it's some sort of blasphemy my question? You all do it (those who clean and oil watches), my question is how and why?

Assembe movement and let it run 5 minst. Afterwards I do it using 9415 on every second teth tip of the escape wheel.

Only on the tip of it not on the top or bottom of the wheel

I check it under the microscope after 24hours of work if its not enough i do it once more

Enough is when the escape wheel tip and the pallet jewel meet you shoul see a droplet of oil between them which is aprox. 30% of the pallet jewel tip length(its dificult to explain)

And of course i use epilame as it makes this job a lot easier and the grease stays in place afterwards and does not travel along the surface which will leave the pallet jewels dry, at the begining i said let it run 5 mins, this will wear of the epilame coating and will leave the oil on that places.

I hope i made it a bit clearer for you now

Great info.. Is there any tutorial on the site for using epilame? I've never used it, just oiled the pallet stones before fitting. I am now concerned after reading about the oil spreading, and leaving the escape wheel dry over a long period of time.

You treat the whole escape wheel with epilame, and only the pallet fork jewels (avoid epilame on pallet staff).

Assemble the watch let it run 10-15 mins to the contact point between escape wheell/pallet jewels epilame is worn out then you apply 9415 and you test after 24hours if less than needed then you reaplly more.

And yes youre right, drying the escape is main reason for watch stopping after 1-2 years after servicce

I have seen amplitude of 120 degrees over the years before applying the 9415 and after applying

Have a new little project .A vostok 2409A watch . Have actually serviced almost the whole movement but have seen in a video that the pallet fork ends should be oiled . Can't find the video . What oil shold i use ? Have D-5 or 9410 . Or is their any other i can use . Is it ok to skip the oil .

I think you can get away with Moebius 9410. It sometimes it is ok to use it instead of 9415 and/or 941 (I think those are the numbers, first for high bit movements and second for low bit movements).

Since we're on the subject of lubricants, what basic lubricants (oil and grease) should the hobbyist have on hand?

 

This is a great question. It would be nice to see a list of lubricants with an acceptable substitute/multi-use suggested. I have a small fortune invested in many oils/greases and the shelf life is only so many years and I'll never use them up.

 

Mark, although you're a pro and would have on hand all needed oils and greases, is there anything you can put together that would help us novices/hobbists?

 

Many thanks in advance and I'll follow this closely. :)

Hi all,

I believe we have extensive info on oils on the site where the questions here have been answered. Just do a search "oils" or "lubricants". If I remember well there is a viscosity equivalence chart that may be very helpful...

Cheers,

Bob

You are welcome gotwatch, I'm glad you found what you were looking for. I figured it was a better way considering the tons of opinions and information already on the site. Please, don't hesitate to ask more questions, I didn't mean anything by the suggestion, just wanted to be helpful.

 

Cheers,

 

Bob

Bought six Vostok movement to work on . Needed a better balance than the one i got . Hopefully there is one in the movements a bought . like to work on this movement as they are easy to find parts .And the parts are very cheap . This is the service work done by someone at WUS . The movement is a 2414 but that is similar to the 2409 .http://forums.watchuseek.com/f54/vostok-caliber-2414-service-notes-very-long-many-pics-226237.html

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....

      yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?

      Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
