Cleaning and oiling balance and jewels


Recommended Posts

Hi.

I have just gone over to Renata after trying Perchloroethylene, which I found to be useless, found it took hours to evaporate of the balance and was not convinced it cleaned anything.

Mind you the Perchloroethylene did come from eBay so might have been anything in the bottle, as you have no guarantee you get what you pay for on eBay 😞

 

The stuff I have works well but I mainly use it to soak balance jewels. I stick the balance in the wash with the rest of the movement.

No it's not, have a look on ebay £15 for 500ml! 

Not yet a complete ban perhaps, but it's striclty regulated because of its toxicity - please note I am just stating a regulations fact, not saying that one gets harmed by occasionally using it. I have attached a document with a summary of these regulations starting page 7.

I do not agree with these blanket statements. Ebay is just a website, not the seller, which you can effectively evaluate independently. And as with other online purchases you're actually well because the right of return, and the PayPal "not as described" powerful claim policy.

Get yourself a can of Ronsonol to clean hairsprings or the complete balance it is safe with shellac.

Worth always to remind casual readers that this is just your personal suggestion, Lighter fluid it's not an horological product, it's not recommended by any maker, school or book, and cost 4 - 5 time per quantity as opposes to petroleoum ether of guaranteed purity.

Great Statement but not being a Chemist how do I prove what is supposed to be in the bottle is not in the bottle?

If it does contain what its supposed to contain then I found it rubbish for hairsprings as it was far to slow evaporating.

I will now wait for jdm to criticise Ronsonol as he always does. 🤣

Hi

There appears to be two types of Ronsonol, the Old version Contained Naphtha and the New Version contains Petroleum Distillate which I understand is not Naphtha

Which are you using

I have I purity Naphtha is that OK to use.

Is not? Same with any purchase we make, we chose based on the producer and seller reputation. Not the fact that is bought on Ebay, Amazon, or whatever other source,.There is also a document called MSDS that details composition and hazards, I have attached an example.

Naphta is a very generic name, it means different thing is in different contexts and different countries: https://en.wikipedia.org/wiki/Naphtha

In any case t's a distillate of petrol, exactly like motor petrol or diesel fuel etc. https://en.wikipedia.org/wiki/Petroleum_naphtha

I don't remember which thread it was with the never ending Ronsonol/benzine/naphtha debate but I mentioned some of this there-

 

my local chemist sells Benzine 60/95, ; this is a really standard product every watch and clock workshop here uses. He told me it's the same as Ronsonol, just more pure. He uses it in his Zippo, I use it in my camp stove, and also for cleaning some parts of watches and clocks.

 

Some years back I tried to get clever and buy some Naphtha, which I thought was lighter fluid. At this time I was trying not to use benzine too much and for some reason thought Naphtha was safer. He thought it was a weird thing to buy and told me to use benzine, I was pretty sure I was smarter than him on this. It was sooo stinky that I still have probably 998ml of the liter I bought.

 

What we call Benzine, the good one that works well for watches, is:

CAS # 64742-49-0    Benzine, aka Petroleum Ether, aka Hydrotreated Light Naphtha (and some other names)

 

The stinky horrible stuff I thought I was being clever buying is:

CAS # 64742-95-6     Solvent Naphtha, aka Petroleum Naphtha light aromatic

 

Seem pretty similar but I will never open the Solvent Naptha again.

I used it way back in the 70's & 80's so at that time there was only one. Another good thing with Ronsonol it is very good for removing the muck after you have removed a sticky ticket.

But this one started with a different question:
Which specialized hairspring cleaning fluid is best?
And another good question is:
Is a specialized hairspring cleaning fluid really necessary?

Your opinion?

I clean the balance complete in the cleaning machine; if for some reason I need to re-clean, ideally it's back through the machine, haha. But I will clean them in fresh clean benzine too. I haven't had or used One Dip or similar in 20 something years.

Too right. eBay gets a bad reputation from the tiny minority of rogue traders and dodgy individuals! It's 10 times better than AliExpress etc.

Ok, I will rephrase my eBay statement as it appears to have offended some.

The problem with most if not all large on-line selling platforms like eBay, Amazon, AliExpress, Banggood etc is that they are just a selling front to a huge number of independent traders and among those traders there are some you sell counterfeit products, some deliberately and some without their knowledge.

Buying from these traders is sometimes a big risk, I have in the past bought Al sorts of things that were packaged as a genuine original item but they ended up just being poor quality fakes, these have been things like batteries, memory cards, tools, chemicals, even glue.

Can't remember the last time a shop sold me counterfeit stuff over the counter.

There is that better

True. So as mentioned above, it's about consumer's good judgment at the moment of purchase:

  • Do not buy at the lowest price, as when the price is too good to be true.
  • Buy from an official shop, as e.g. there are many on Amazon.

That being said, worth to remind again for the casual reader about PayPal's (and also Amazon, Ebay and AliExpress, plus the card issuer in last instance) protection about counterfeit items. No need to return the item, just a picture of two and clearly explain how one can tell it's counterfeit. They will immediately refund. After a number of cases, the seller will be banned from the platform.

You can buy this from chemical suppliers from ebay. I used it (and still do) in a small ultrasonic for cleaning all parts, before a final rinse in isopropanol to remove oily residues. 

It works well, but I have since switched to Elma WF Pro cleaner. You can just hand dip if you don't have a machine. It is much better at removing dirt (the detergents?) than Naphtha and leaves a nice shine on the plates. 
I rinse with isopropanol - but only a minute or so in the ultrasonic for parts with shellac - balance and pallet.

    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
    • Moved in. Now working out the best place to have things so moving around the room makes sense. The wooden movement testing rig may end up being suspended from the roof with some pulleys and ropes that I salvaged from some alfresco blinds that we replaced. I always seem to salvage things from things we scrap thinking, "I have an idea what I can use these for." I hope I'm not the only one that does that. My wife hates me for it. "What are you going to do with all this crap?" Anyway, here you go. If anyone has suggestions for workflow around a room, speak up. All Ideas are appreciated. The bench on wheels will carry either a laptop or my Samsung table for using with the little camera that is on the tripod for photos while dismantling etc. The small bar fridge in the corners going to have water etc in it and I might move the coffee maker from the kitchen out there as I am the only one that uses it. I want to get an ultrasonic cleaner so I may set up some sort of cleaning rig in front of the glass of the sliding door. Where the grandmother clock is currently standing. I'm hoping that I will be able to transition my working area, which is the table that the stool is sitting in front of, fairly easily between clocks and watches. I'll be doing my best to make sure that tools for each are separatedwhen stored. Logistics. I'll have a bit of wall space for being able to hang clocks if I find some that I wish to keep or hopefully at some time to be able to hang customer clocks for monitoring after servicing/repairs. The clock on the left in the blue pillow slip and the grandmother clock are earmarked for  Jarryd and his wife, Sara. He helped me move the benches in today. And then went on to tell me that ticking clocks drive him nuts. Who doesn't like the rhythmic ticking of a clock? I have a green pad for adding to the bench for a working surface. It is not a cutting mat or one of the Bergeon mats. It is actually a green desk writing mat. Was really cheap and will do exactly what I want, I think. I also have to get the sparkies back that put our new stove in to put some power points on the walls behind the benches. Hopefully this is all going to go well. I'm excited about it. It'll beat having to live out in the garage doing it. The other thing I have to do is cut a circle or square of plastic to go over the bouncing watch or clock part black hole in the middle of the floor. I would pretty much guarantee that anything that sproings off the bench would end up going straight down that drain. 😄      I think I have been on this forum about 4 years and still yet to really strike a blow. That's a bit sad isn't it. Signed up to Mark's watch course and have yet to buy the movement for working on. Have most of the tools I think I will need so now all just a matter of will.   I have to make a crank handle for my Joe Collins spring winder as well and some spring retaining tubes as I can't find where I can buy them. I will be salvaging (here I go again) the aluminium tubing from my old hang glider which I have to scrap as I can't fly anymore and it is too old to sell. All the aluminium tubing is aircraft grade so I am hoping it will be suitable for the winder. I have also been making a bushing tool and I have just worked out that it will work well with my Dremel stand. So another thing that I can turn into a working tool. Don't know if you guys have ever seen the ad about the guy that buys himself a new 4WD and the son says "We're going to need a bigger boat." So Liz is looking at all the stuff we have to get rid of and says "We're going to need a bigger bin." Really difficult to work out how big a Dempster bin we need. Sigh.
    • So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.
    • Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.
