I have a retaining screw on a gearbox shaft that appears to have been broken off. This is on the IJ path of adventure mini playfield.
Since it's metal, I don't think I can use some of the usual wood screw removal techniques.
I drilled a small hole in the center of the screw, but didn't get much past that.
Because it's a shaft, I can't really press too hard down on it with anything.
