just wanted to thank you guys for this post. I have exactly the same problem on a Seiko movement. I think  the cleaning fluid removed / degraded the fixing. I now have to reposition the hair spring to the stud. What is your opinion on using superglue? I think I will use Devcon epoxy 60 min.

I leave the option to remove open, I use a type of glue that can be removed, should there be a need to do so. Epoxy is suitable.

Hi Nucejoe

It worked a treat. Could not video though as the microscope was too near and obstructed my progress. I will take a still picture when I can move the balance and post it here. Once again many thanks for the tips. Brilliant!

As an aside guys, nothing to do with the Seiko.

I need a balance staff for a Lancashire Watch Co Prescott pocket watch number 719184.

Does anyone know where I can obtain one from or the balance complete?

Hi . Getting what you see, kinda eases the bending at the end length of breguet HS.

www.balancestaffs.com  lists only one staff for lancashire, a 16s , is it what you want?

 

Hi Nucejo

I have looked the measurements and they seem about right. I will double check before ordering

Many thanks for the link.

:)

Glad to hear the good news though, as quick as you absorbed the idea, excellent results was a certainty to come..

I was watching a youtube video on the co axial escapment on Omega's channel. In it there's a snippet of the balance complete assembly process. It goes like this: stud is mounted in stud holder, balance with hairspring is seated in bridge, end of hairspring is slotted into stud, a heating element is brought to contact with stud, a flake of something is dropped into the slot, the something liquefies instantly. By the looks of it I would say they use shellac.

What is denatured alcohol?

I am using Elma Suprol Rinse. Is this good or bad and is there anything better?

 

In the UK that's methylated spirit, typically purple coloured, used in spirit lamps as it's clean burning.

This particular one is not possible to pin unfortunately. The best remedy is to clean out the old adhesive and apply new. I would use a slower drying epoxy (very very small amount applied using a clock oiler for example). Apply when the glue is tacky enough to hold the spring in place so you can test if it is correctly positioned. Once you are convinced of its correct position along the length of the end of the spring then leave it to set.

Do this with the stud re-attached to the index but the hairspring not attached to the balance staff so that you can check the position of the hairspring collet being directly over the pivot hole. This will make it easier for you to observe that the spring is straight and true on the stud.

You should use shellac flake and apply heat using an old flat oiler

I am not sure to who you were suggesting that, but if it's our Host Mark Lovick, he is an accomplished watchmaker, author of some hundred excellent YouTube videos, and producer of a complete HD video training. I suggest that you give these a look for a chance of learning one thing or five.

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      I have read some suggestions that it can cause wear , particularly on the fork horns of a fully treated pallet fork. I've had half a kilo of steriac acid powder on a shelf for almost a year now, might have a little play today with a heater and a jar.

      As I'm only cleaning watches in small numbers at home, I pre-clean any significant deposits of old grease and oil before using the cleaning solutions. I scrape off deposits with pegwood and Rodico, and if really dirty, wash parts in naphtha with a brush.  So I'm happy using DX, but can understand why it's avoided by the pros.

      Any tips to correct a sloppy error?

      By Neverenoughwatches · Posted

      I think attaching a nut to the lid to pull it off is the least destructive, any damage damage on the outside is going to an easier fix than any created when trying to push it out from the inside. Scratching up the inside of the lid , mainspring or arbor bearing will be risk. Just my opinion.

      yes the things we read in the universe I did see some where it was either difficult to clean off or it contaminated the cleaning fluid there was some issue with cleaning. I was trying to remember something about grease where as opposed to a substance of a specific consistency they were suggesting it had a base oil with something to thicken it. That conceivably could indicate that the two could separate and that would be an issue. But there is something else going on here that I had remembered so I have a link below and the description of the 9501 notice the word that I highlighted? Notice that word appears quite a bit on this particular page like 9415 has that property all so they 8200 mainspring grease and that definitely has to be mixed up when you go to use it because it definitely separates. just in case you didn't remember that nifty word there is a Wikipedia entry. https://en.wikipedia.org/wiki/Thixotropy   https://www.moebius-lubricants.ch/en/products/greases I wonder if what you're seeing is the boron nitride left behind after cleaning. In other words it's the high-pressure part of the grease and it's probably embedding itself into the metal which is why it doesn't clean off and shouldn't be a problem?

      Yes and no. I use Moebius 9501 synthetic grease and it is significantly runnier than the Moebius 9504 synthetic grease (and I assume Molykote DX) that I previously used. I haven't seen 9504 spread and it is in my opinion the best grease money can buy. However, my current method of cleaning doesn't remove it from the parts, so that's why I have decided to use the 9501 instead. I believe I read somewhere that Molykote DX too is difficult to clean off. Thinking about it, I'm pretty sure my 9501 grease which expired in June 2022 is runnier now than it was when it was new, but whether new or old it always needs to be stirred before use. So, that's why I treat the parts of the keyless works, cannon pinion, etc. with epilame. That was very thoughtful of you and something that had completely passed me by. Not sure what the epilame will do when it wears off in a non-oiled hole. Anyone?
