mainspring wont catch

Recommended Posts

Hey guys

I have been trying to get this mainspring to attach to the arbour. First attempt went bad i tried to bend it gradually to fit but the bridle broke. Is there away of doing this .

Do i try again to bend the spring to fit arbour in the barrel? out the barrel?

This is the way they both came i mean i have not touched this one in the photo at all. All other springs on most other watches seem to be a bit nearedto the arbour if not touching  than this one.

Any ideas.

cheers

if it's a blued steel spring the center part is usually soft you can usually close it when it's in the barrel. It's a modern white spring it shouldn't look like that at all if it does its defective.

then modern white spring is as you found out attempting to close the center or anything usually results in breakage. If you put something in the center when it's out of the barrel you can gently squeeze it and slowly close it if you're careful. But anything resembling bending of light spring is usually ends in disaster

Bending and wrapping pliers. 

 

 

Having broken several springs trying to close the central coil, I've been looking for some of these pliers, small enough to use on wristwatch springs. 

These are the smallest on Cousins, but are they small enough ?

    • 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
