7750 rotor post has a broken screw inside it

[johnbiggs]

Hey, guys, I have a 7750 movement where the rotor screw snapped off. I opened it up and it appears the rest of the screw is still inside the rotor post. Is there anything I can do to screw it back out?

One method is to grind a slot into it with a Dremel tool with a thin disk on it, then screw it out. Another method is to make an extension to it with epoxy and a metal pin or even a toothpick and when it hardens, use the pin to turn it out. Someone else can chime in with other ideas. Steve

You can see what I'm seeing here. I can't get a new rotor screw in that hole.

Or

Make the same scenario using  a reverso staking tool using two screw-removing stakes.

 

...just thinking out loud

 

The other option would be to disolve the screw using Alum.
