Installing Vostok anti-shock spring

[Endeavor]

Hello All;

I have some problems installing anti-shock springs from Vostok 2415 / 2416b movements.

These movement have these 3-leaves springs;

Taking them out is not such a problem, but inserting them is for me another story. I drilled a 1.5mm hole in the center of a peg-wood and sharpened the edges. While pushing down and turning the spring with the peg-wood to install, one spring leg / leave broke off. I find with the peg-wood, if the spring is off-center, the spring hard to correct and to get the leaves to engage in the slot. Most likely I tried too hard, and one leg broke.

What systems / procedures are others forum members using to safely install these springs?

Hope to hear.......

Thanks on beforehand

Roland.

Let's call them spokes to simplify things. Push one spoke in under the rim across from the notch but have another one over the notch ready to push down and under the rim then gently push that one to one side in a circular motion until the last one is over the notch push that one down and under the rim all done with thinnest tweezers. Did that make sense.

Oh forgot to say when you have all 3 spokes in it should be straight and central to the jewel as your plc.

Hi Endeavor,

Is the photo you posted the actual watch ? the end curve of the hairsprings looks a little off. Once you've sourced a replacement shock spring you may want to tweak it a bit. Mark's video's helps.

@Cad101 & @anilv Thank you both for your replies

First of all, the picture is not from the actual watch, just taken off the internet for conveniences and purely to show the spring-type. 

I'll try your method Cad101, even though with two spokes (spokes is indeed a much better word, thanks!) in the rim, trying to engage the third spoke, the spring gets loaded for a jump into infinity. That's why I initially liked the idea of the peg-wood on top, to hold the spring down. Perhaps the peg-wood idea is better suited for the type of springs were all three (sometime two) points / spokes have to be engaged simultaneously ?

Will try this morning but will vacuum clean the floor first......

Thanks!

Roland.

@Cad101 Did nearly what you described above, apart from that when the last spoke was above the notch, I pushed it down with the center-hole peg-wood and rotated the spring in place. It felt (for me) that the risk of a jumper was reduced significantly and that worked very well !!

Both cap-stones have been cleaned & oiled and are safely back in place...... thanks a lot for your help !

@anilv Had a look at my new hair-spring and if you talk about the apparent kink, my hair-spring looks identical as the one on the picture.

Your welcome glad I could help I forgot to mention I usually use two sets of tweezers one to hold the spring down while turning the other but your pegwood technique seems to have worked well enough

Yes Mick; I figured that's where your second tweezers were for. I'm not equally good with both hands, so I have to come up with alternative methods. With the center-drilled peg-wood it was just a matter of starting at the low two spoke side, gently pushing the wood over the spring and pushing down the third spoke, followed by a little twist. With the peg-wood I felt I was on top of it and the spring had no where to go

Each time one masters a bit more of watch technique..... thanks for your help!
