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.

They showed up! It's a perfect fit. Can't wait to populate it and try it out.

Lubed up, back together (minus the one screw), and I'd say not a bad result! Going to give it a day or two to run in while I clean up the case and regulate it again, but off to a good start.

You'll have to strip it back anyway.

As far as I know, the only time an epilame treatment has potential drawbacks is when something is rubbing on the treated part w/o lubrication in between creating abrasive dust. That is, I don't believe in the method of "running the watch to make a groove through it first in the pallet stones where the lubrication is then placed". So, I think the rule would be; do not epilame treat parts where rubbing is going on without lubrication. Other than that I don't think we have anything to worry about. That said, I'm not an expert, and I'm always happy to learn more. Has any other repairer than Alex suggested or explained the "making-a-groove" method? My impression is that it's just something he constructed in his mind. I have not perceived it as a generally practiced method. Again, I could be wrong!

Post some pictures , some good close ones of the parts you've described.

Ive never used epilame H only information i have read and mentally stored about it mostly from Nicklesilver here and elsewhere ( the fork horns thing ), maybe the residue powder that is removed has some grinding effect ? So probably a good idea to limit its application areas to only the absolute necessary. Yes as far as i know epilame rubs off relatively easy, the technique of running the watch to make a groove through it first in the pallet stones where the lubrication is then placed. This i understand creates the barrier for the lube to sit up to. If i can find a good balance of pros and cons of its use then thats one process i can avoid by using a thixotropic lube on the stones. The epilame i would say allows for a more fluid lubrication to be used that would increase amplitude on low beat movements. The stearic acid powder is extremely cheap, the problem is the fuming process to coat parts, is not selective , the whole part has to treated in this method. If epilame residue can cause wear then thats not good, if I remember the conclusion was not proved entirely just a general assumption between watchmakers. The thread is out there somewhere, the same discussion is also old on a facebook group.

I’ve had a couple movements where it is clear the previous watchmaker was diligent with lubrication but the old epilam had turned to a fine white powder covering the pallet fork and keyless parts, which can’t be good for parts. I’m spare with epi since I don’t know how long it takes to degrade to that state…

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?

I've used expanding foam for lots of things but i thinķ you got me on that one.

Put the arbor in the barrel in the correct direction and look at the hook of the arbor. It will show You the direction of the spring.

Hello and welcome from Leeds, England.

Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue. Maybe someone will have a better answer.
