In this month BHI mag (August 22) it has an article on “Pivots and Re-Pivoting”.  It covers all aspects of this job and the different methods used. On burnishing the author states that he has used Olive oil for many years as the lubricant.. I have never used olive oil but I will try it out. Wondering if anyone on here has tried it.

Coconut oil has the hightest concentration of saturated fat than any other food source, so it has a very slippery antifriction surface property.  A better choice ? 🤔 . A bit easier to apply also ?

Another suggested lubricant for burnishing is Oil of Wintergreen. Side benefit of using it is that it smells really good 🙂

Hadn't heard about Olive oil. 

Cheers!

There's a bit of superstition surrounding pivot burnishing. Around here the old guys like lavender oil, but some swear by almond oil. I have a really old bottle (with a cork) of Moebius chronometer oil that was my magic Jacot stuff when I was younger. In the end a good thin oil is what's needed. I have almond and lavender in the shop and like both. If they aren't within arm's reach I might use thin clock oil. For quick cutting the thin lavender is the best.

 

In my pivot burnishing machines that use carbide wheels, an industrial one and a Rollimat, I use deororized kerosene. If I try thin oil I notice right away a reduction in the cutting action.

"Traditional here is pure lavender or almond oil, but 9020 or 9010 is ok (but expensive). For some reason the natural oils seem to work better." ~@nickelsilver

I have been using 9010 with good results. Not expensive for me as I'm a hobbyist using minuscule volumes of 9010 for my watch work.

Any motivation by the author for using olive oil? Did he mention what kind/brand of olive oil?

No mention or make I did notice on a site it must be virgin olive oil but sure if it was just a tongue in cheek comment.

I try some of the olive oil we have in the kitchen.

(OT, but I'm generally very suspicious of seed oils because they form aldehydes (highly carcinogenic) when heated in a frying pan. I always use real butter when frying. Expensive as hell, but better than cancer. In my opinion, food products made from seed oils are unfit for human consumption.)

Quite right watchie you do need to watch your pan heat with some oils, rapeseed is another, both are far healthier as a dressing. Best oil is as you say pure butter from grass fed and finished animals if you can get it for red meat, coconut is good for most everything else.  But worse still is the Teflon that is coating your pan. This stuff is terrible and it doesnt leave our human system for decades. A good quality carbon steel pan is your best choice and then learn how to properly season it. One of the most healthy food choices you can make and always my first recommendation when i give advice would be to completely cut out processed foods. Reduce your preservative intake as much as possible, not easy, salt a relatively safe option. The caveman didn't ingest chemical or grain for that matter. If we get on to diet i will waffle on for hours lol.

I have used my own spittle at times. 

Oldhippy,

Since I read this I have been trying to remember a conversation that I had with an older gentleman about 25 years ago.

He is either now long gone or his participation would no longer be of any contribution.  His story was about a conversation he himself had with an older gentleman from his past.

The story, as I remember it, was that he rubbed his finger around the inside of his ears or under his eyes while performing  delicate work like this.  I just can't remember what that work was.

I read a similar technique in an old book. That the  old watchmakers would draw a watchstem down the crease of their nose to grease it before inserting it in the watch.

I have heard of that someplace also.  But I've also noted that probably not everyone should do that.  I've worked on some vintage watches with nickel-plated brass cases, and something about the owner's skin or sweat or body chemistry would eat away at the case, and it would be covered on the underside with pitting and patina, and the nickel would be eaten away.  I don't know if it has something to do with alkali content or what, but if I knew my skin did that, I would not rub any watch parts on myself.

I have a few old watches around 80 years where the case backs are very worn and almost eaten away. I cant imagine anything else but a chemical reaction between the metal plating and the owners body could have caused this.

    • Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers
    • After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.
    • Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.
    • Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.
    • isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
