pallet staff exchange

[matabog]

Hello!

I have a question, if I may: is there any way I could exchange the staff on the left with the one on the right? I would need to push out both of them and push back the good one on the left pallet fork.

The staff is 0.4 mm and the pivot is 0.12 mm.

Is there a stake (4.7mm ones) that small? I need to change it because the end fork is damaged (don't know if you distinguish in the second photo).

Thank you,

Bogdan

Use a jewel press, not a staking kit, as the placement of the fork vertically on the staff is critical... there are pallet staff pushers available for all of the jewel presses (Horia, favorite and seitz)

As Flyingwatchmaker says.  When you have swapped them over you will need to ensure that you set the height of the staff correctly in the fork. If you check out the thread on banking pins there is a link to a raul horology page with a picture of the alignment you need to achieve.

 Thank you for the advices!

@FlyingWatchmaker  At the moment I don't have a jeweling tool, just a staking tool. The straightness is pretty ok - I will try to make a diy punch from a G28 or G29 needle - I'll put it in a 0.35 punch and push out the axle. To put back the axle in the other pallet, the 0.3 punch should work.
We will see

@StuartBaker104   I have that book

Do you know if you can buy a new pallet if it all goes horribly wrong? What's the movement?

it's just for fun

the watch is ok, I had a good spare pallet. now I am playing with two scrapes. One has a broken pivot and the other has the fork affected (the impulse jewel end) - I got nothing to lose

the movement is Landeron 48 but I don't think it matters - a pallet is a pallet is a pallet

Landeron 48 pallet is about £30 on ebay... feel free to risk what you have in the name of education or use a scrap movement and take the staff out then replace...

On the right side you can see a G29 needle tube. It is 0.33mm/0.15mm (ext/int diameter)

Now I have to put them back.
