How to remove this stud?

[VWatchie]

I was going to make my first attempt at static posing on this watch (Vostok cal. 2414) when I discovered this version of the movement has a different stud arm than all other Vostok 24XXs that I've seen, and I've seen quite a few. This watch matters to me so I've been practicing the procedure at least five times on a scrap 2414 where the screw is also friction fitted but with a different construct which can be seen next...

This type of stud arm is also a bit tricky but I've made an eccentric screw to separate the arms to make the stud fall out.

I've tried to push out the stud (first two images) using sturdy tweezers and some force but it won't budge and I'm afraid using too much force and things could go terribly wrong. So, any tips or advice?

Russian ? I have tried but has also failed. I took the easy way and took a complete set from an other movement. Can probably be removed with a staking set.

There is no threaded holes on this side either? Then it's tapered shape and friction fitted.

If you feel lucky - Kendrick & Davis Inverto Staking Tool is your friend.

But would check the opposite side first to see if it will be safe to apply pressure to reinstall it. Some of these studs have thin walls filled with some sort of epoxy to hold the hairspring.

This is what happens when you get really cheap watches they skip parts. You may find that it's not actually tapered it just Friction in as it's probably really not meant to come apart. But you may still be a little push it out it's probably not tapered either.

The other option would be to unpin the hairspring providing they have a pin?

What would be nice is to have a parts list with pictures but I bet that doesn't exist.

It all depends on how hairspring is attached to the stud and tools at your disposal.

If glued, you might just take a solder gun to the stud and burn the glue.

If pinned !     unpin.

if laser welded remove the stud in a staking set. 

You might just remove cock and balance assembly,  place it on a hard surface  ( cock down, balance up) then press on the stud arm to break the stud  loose then push the stud stud out with pair of tweezers, one prong of tweezers under the stud arm, the other on the stud.
