Does anyone have any ideas about removing badly rusted out screws from wood? I attach two photos of bellows frames from an Ansco 8x10. The bellows needs to be replaced, but all the bellows frame screws are completely rusted. Aside from the bellows frame screws the woodwork is in good condition, although the hide glue has given out in most joints.

If I drill the screws out I don't think it will go well (a hand drill would probably slip off the screw head). I don't have a drill press - and the screws in the back standard would not be accessible using a drill press, the frame would interfere.

I don't expect that easy out / screw extractor tools will work well, but wonder if anyone has tried them in a similar situation? I have a feeling I need to cut the bellows frames out in order to get access to the screws to twist them out with pliers, but even then the screws might snap off and I'll need to replicate the bellows frames. Any ideas would be welcome. I'm in no rush with this.
