Screw organisation

Recommended Posts

Hi all, I am bout to embark on stripping my first watch a raketa.

 

Few questions which I have.

 

How do you know which screw hoes where? Experience? I have purchased a 60 compartment pill organiser, and I intend to put them in order and then remove in order but how do you guys do it.

 

Secondly , does a cheap option exist to clean the internals or is a sonic cleaner the only way to go?

 

And my first lesson learnt, good tools make a difference , the eBay ones are now in the bin and the expensive ones are amazing

1. Experience first and foremost. Trial and error too, sometimes. You can take photos of your disassembly or you can put each part with its corresponding screw(s). Some you just know where they go, after you've done this a few times.

2. You don't need an ultrasonic, of course. It does help to have a couple of chemicals to clean components if they are really messy, rusty and so on. If it's a clean watch that hasn't been serviced in a decade or two you can just clean it lightly just be careful and patient when you do it.

Pictures is great when you disassamble the movement. Place the screws in the same apartment in the box. next to the part it would fit. 

Raketa is not the most complex movement as they have the same size screws in the trainwheel bridge and the pallet fork bridge . So even if you would mix them up?  You could probably figure it out.

I only separate out the 'left hand threaded' and 'shouldered' screws... this simplifies things a bit. You will waste time trying to fit a LH thread screw into a normal hole!

Otherwise it is trial and error. Watch out for screws which are too long and project out the other side. Also screw heads which are too thick will create problems, eg wrong screw on a pallet-fork bridge will interfere with the hairspring.

I screw them back into the hole they came out of once the the part that they secure has been removed. That way, so long as the screw was in the right place in the first place, it will remain in the right place.

It also means that all of the screws go throuch the cleaning process and there is little or no likelihood of them getting lost.

The only negative impact is that it means that the threads that are actually engaged don't get quite the same free flushing of cleaner that they otherwise would, but then why would they need it? there should be no oil or dirt in those threads as they have been engaged to pretty much the same degree since the movement was last cleaned.

If, whilst dismantling the movement I spot anything that warrants different treatment then obviously it is dealt with accordingly, but that is a real rarity.

This is just a habit that I got into when I first started this game and haven't got out of. In truth you will find that with experience you will be able to identify which screw goes where with only the minimum of trial and error, even with a movement that somebody else took apart (I have done this), but I like the extra security in the cleaning machine that my approach provides.

    • So I found what I believe is the setting lever screw! Am I right in thinking the screw next to the click is the correct one for the setting lever? However if it is, it doesn't fit in the hole which I believe is for it! I can get the lever to sit nicely on the stem and line up with a hole, but the screw only goes as far as the shoulder and stops. It's as though the hole is too small! The dial side has been disassembled by the way, the other wheels are in my tray
    • When faced with say a pocket watch bridge which is cracked, silver soldering to repair is often the only option (hopefully someone wasn't there before hand with soft solder). I can generally do this succesfully and tidily with a small torch and miniscule pieces of silver solder, but on parts which were mercury amalgam gilded the heat can have have a deleterious effect on the finish.   I keep wondering if there's a good way to refinish these - and despite having the needful items would rather avoid using the mercury process.   In the past for electronic work I've gold plated PCBs but this involved gold potassium cyanide solution, which also doesn't realy belong at home. I've read that there are now safer alternatives but couldn't find more detail (and importantly how similar are the results to amalgam gilding, since I wouldn't want to refinish the whole watch). Pointers would be very welcome (and yes, I know solutions containing gold won't be cheap!) Alan
    • The first one is an Unruh max stake for pushing out staffs
    • Ok so with the great answers for my previous question may I ask what these two attachments are used for. The one with the red knob is I assume used for hand setting the seconds hand? Jon      
    • According to Cousins site I need to look at document G22 as I think I need an ATGB at 304 but I cant find this size in G22 doc. The last thing I want to do is order the wrong one😳  Unless I cant see the wood for the trees 😆 I could be looking at the wrong style, I assume its classed as Round plastic Armed  https://www.cousinsuk.com/product/wide-ring-gold-atgb
