Hello,

I'm just a beginner, too, and I'm verry interested in mechanical watches at all. I'm a physicist and engineer and work in a university of applied sciences in germany. 

Because I get a new watch from "Mühle Glashütte", there is a high motivation for me to do the service by my self. So obviously there will be  5 years time (following the manual) to learn how to do that until the first service will be necessary (please excuse my poor englisch - it's not my highest qualification 😉). I will did my first practice on a Seiko watch with a 7S26C movement. And I dissassembled it following the youtube videos, clean it and put it together again two times, and it's still alive 😀.  But it has some problems I'm not able to solve - I will post in a an other threat. I do al lot of 3D-printing, so I developed a couple of tools such as a movement holder, a wheel centerer and a hand placer by my self and produce it by my 3D-printer - and all works fine 😄

Thats all from me for this time and I'm verry glad to be here.

Many thanks and best regards from good old Germany

Welcome.

I like the sound of the 3D printing, you'll have to post some pics of the tools and movement holders you have made.

I quite like the look of the Mühle Glashütte 29 ER Day/Date on the metal strap and the chronograph with the white dial.  I do like a red second hand on a watch too.

Many thanks! 😀

Yes, your are right, my "Mühle" is a 29er, too . Because I'm not at home, I can only post the rendered views at this time. You can see the hand placer an some tiny tools such as the wheel centerer, the movement holder but also an oil bowl and - I don't know the correct name is - a barrel assebler. Some of them are made out of CFK-PLA such as the lower part of the barrel assebler, the movement holder and the hand placer. To get a fine surface I presst some hot ball-bearing balls in the pits of the oil bowl. All axes are made from 6mm-steel and the threaded rods are M6x1🙂

best regards

Tobi

Herzlich willkommen, herr Tobi.  I have lived in the US all my life, but my family can here from München and surrounding cities. Ich spreche eine kleine Deutsch, aber es ist lange her, dass ich diese Sprache viel gesprochen habe.  I need to practice more.
Enjoy our forum.  It has many valuable resources.  And there are experts here who can help with a wide range of difficulties.  Have fun!

Hey UhrTobi!

Great to see your 3D printed stuff.  Certainly interested in your watch-related creations.  I am a big 3D guy myself.  I do my designs in FreeCAD (because it is free!!).

BTW...your English is better than my German!!!  I used to teach a short course in Berlin (twice a year) back in the '80s.  Learned enough to get around but have since lost it.

Nice work.

Nice.  Intrigued by this comment: "All threads must be cut and all holes must be drilled using alcohol, otherwhise the PLA stick to the cutter tool!"  I know that drilling pla is tricky because the friction heats up the bit and melts the PLA.  Is alcohol (IPA) the solution?

Here is a thing I made to stabilize a balance cock while working on it.  I posted about it in the tools section. It is just a puck with a bunch of holes in it.

Hello,

 

in the link above, there ist a universal movement holder implemented. I used it since a view weeks and it works fine.

There must be any sort of cooling. I use ethanol (we call it in germany "Spiritus" - it is ethanol with a additive so it is not possible to drink and because of this, there is no alcohol-tax on it). But IPA woud work, too. Water would be a solution, too, but I do not use this because auf corrossion of the tools. Eaven oil would be possible, but I'm not sure, that there would be no interference with the PLA.

Looks like a practical solution 🙂

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring.

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.

      Epilame / Fixodrop

      By Waggy · Posted

      Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8

      Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?
