How to replace this incablock

[richiesgr]

Hi

After a lot of work (because I'm a beginner) I've lost the spring of an incablock(it was in my tweezers then he disappear literally).

I've managed to get another one from another movement. the same one

First question: can I use another spring to replace the existing one

Second question: how to replace this piece it seems impossible to me because it jump all the time you try to touch it

I join the model of the incablock spring

Thanks for your help

Shape the end of the pegwood so it fits just inside the setting, next hollow out the middle of the end of the pegwood so that there is space for the dome part of the jewel and spring. Apply pressure and twist.

 

Good luck.

Looks a kif trio, not incab, there is a special tool for this

Remove and put the bridge on a hard surface to gain more control over the task (important).

     The wooden tool anvil speaks of is a good idea. many approaches have been discussed before.

I slide two prongs in the groove , hold the spring down under my thumb nail ( you have more control with your fingers as compared to tools)  turn the spring with tweezers (move each prong a little at a time) to get the third prong in the groove.  Rinse and dry.

kif trio,

Like so many things in watch repair there is a tool. I have a picture of them so you can see what they look like. Three prongs to correspond your spring. With the tool it allows you to get all three prongs underneath where there supposed to be when you rotate. You can get them without the tools it is just more fun.

Hello

Thanks for the help read a lot about these spring KIF. I'm going to try first with the pegwood tools as described by anilv.

If I do not succeed I'll buy these special tools.

They are not too expensive but I don't know how much use I'll have for them after this movement. 

In any case my advise keep them preciously as the piece price is 3.95 pound + shipping  (not bad for 0.1g of metal).  

Best Regards
