I set a brush bristle into a pinvice, its diameter is around .15

ha ha, mine used to look like a Saturday morning Tiswas Phantom Flan Flinger did it.

what do you use on your pallet stones, epilame and...?

Just realised my previous reply could be misunderstood.

I epilame treat the pallet stones (not the entire fork) but I do not let it run dry before applying the Moebius 9415.

George Daniels is likely turning in his grave over the use of epilame, oiling, and the use of the Swiss lever escapement.

Moebius 9415. Hope that answers your question.

Just browsed it through and found a reference to "Working Instructions", but I would need a login for that and I guess that won't happen without being accredited. I'm super curious to know if Omega recommends the "rub of epilame method" on the pallet stones before applying the oil. Can you please check for us @JohnR725?

I was thinking that yesterday, thats one place where epilame should be, around the backside of the impulse face .

I dont use epilame at all just 9415, thixotropic oil that changes viscosity when its struck. Epilame and 9415 = belt and braces ?

Hmm...

The viscosity of Moebius 9010 is 150 cSt at 20 °C

The viscosity of Moebius 9415 is 110 cSt at 20 °C

So 9010, which is considered a thin oil, is thicker than 9415. Can't find any info about the viscosity at impact but that should be ever lower (thinner). In comparison, the viscosity of water is roughly 1 cSt at 20 °C.

That is true H but 9415 is under the classification of a grease. Theres a lot of oils that have a high viscosity than greases which make little sense to me. But using them both the 9415 seems much thicker than 9010. Very odd, a lube discussion is on the horizon.

Might the specified viscosity rating be measured before a thickening agent is added ? Or that rating is on impact ?

Its like a black hole..... try and escape the event horizon!

You do realise scott that my comment was to entice John back into the discussion

I wonder if 9415 is based on a base oil of 941?

it's interesting what questions bring and the tech sheet answers it's the viscosity of the base oil. Then the impact? There is something we're missing here for that which would have a big influence on all of the house

image above is 9514 image below is 941.then always interesting when specifications do not exactly agree? They ledge above for 941 indicates 110 viscosity but the image off the spec sheet is slightly less but I guess close enough

 

my understanding of the concern of too much 9415 is as we know the loss of amplitude. But why do we have a loss of amplitude? So impact it's basically oil should be very slippery. But what about non-impact? Like the edges of the escape wheel?

Another thing that comes to play here is the shape of the escape wheel itself. Notice on the last a more vintage escape wheel with just a flat surface whereas the modern escape wheels usually made out of steel versus grass much much thinner their contact areas greatly been reduced and sometimes I think there even slightly curved. So is it conceivable at everything that isn't a flat surface on impact is going to be sticky? So this is where the shape of the escape wheel will have a big impact literally on how slippery things are.

Oh and for all of you obsessed with worrying about too much 9415 I never worry about it because typically I'm doing pocket watches and it doesn't seem to be an issue at all. on the other hand I'm much more concerned about a watch that keeps time for 24 hours as opposed to the concern of the group of keeping amplitude for 24 hours. Then yes some pocket watches have steel escape wheels and do look like the escape wheel on the right.

It is John, with a little cornflour added

It needs to be stirred before use and that makes it feel a lot thinner than when in the bottle. Does it feel as thin as 9010 after stirring it? I guess not! Yes, it's strange!

I don't know, but if it is on impact it would make sense.
