Hello!

Could anyone help me with some more detailed information (service sheet, manual, etc) for a russian chronograph Molnija 81322? It was (and still is, from my knowledge) used in MIG 21 airplanes.

 

Two links that I've found:

Thank you,

Bogdan

Hi Bogdan, what a coincidence, I am waiting for one coming from Russia just now. Like you I am trying to find out as much information as possible. I will forward any information to you if and when I come across any.

:) 3D printing is like a dream-come-true. You dream at something at night and then you print it. 

I have a friend who invested in a 3d printing machine, but he still makes small adjustments. This was his first big project - 32 hour job. At first attempt he had some trouble but at the second attempt it pretty much got the job done.

The case isn't perfect but it is ok for this particular project. It has some 0.2mm granularity (layer thickness), it's plastic, and I don't think It is appropriate for wrist watch cases - but I will give it a try at some point.

I'll let you know.

That looks the business Bogdan.  You've just got to fill the star with some red paint to make it look really B).

Mine is still sitting in its original 1980's polystyrene packaging complete with original certificate.

Thank you Geo, but I don't want to make it too cheesy. It's got Mother Russia already written all-over it :D.

About your chronograph, didn't you have it serviced? Mine has the original seals on it (I guess) but I am itchy to open it myself - I think the parts are big and might be a good start on a column wheel chrono dismantle.

I've not serviced mine yet Bogdan, it is NOS with original seals.  It may be a lot bigger than a watch, but It's a complex mechanism built in two layers.  I would recommend learning on a cheap chronograph watch before servicing your clock.

@matabog Wow.......that is a great 3D print result. When I saw you & Geo talking about this chronograph, I was seriously considering buying one. But what when ready? Where to put it / build it in?? I think you found a fantastic solution and my compliments to you and your friend :thumbsu:

While searching for the Mig 21, I stumbled over the Vostok watches. I was so impressed about all the technicalities / capabilities, that I bought yesterday my first Russian time piece; a new Vostok Amphibian "Radio Room"......I can't wait to have a look at the 31 jewel 2415 movement! Thanks to both of you for pointing me East !

@Geo :) Actually it has three (3) layers: one "normal" watch with the train of wheels and barrels and escapement and... wait for it... and two independent column-wheel chronographs. It is quite awesome!

Check out this link: http://www.abbeyclock.com/photos/mig.html

You are absolutely correct Bogdan, a bit of brain fade with my ageing grey matter.  I even had that link saved fir future reference.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.

      Is the Roamer not a split stem? I'm confused on your how your case is put together. If it is a front loader where is it you are putting the case screws? I love me some Roamer, do you have any photos?

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
