I am re-arranging the shelves in an old bookcase, and I'm having trouble removing a few broken shelf pins inside the holes I want to use. They don't protrude enough for me to get any kind of grip with the needle-nose pliers that I used to take out the other pins.
The shelf pins are this style. Quarter inch diameter. Not sure what kind of metal they're made out of. The pin itself is hollow, which rules out most of the common solutions for this kind of problem.
Does anyone have any suggestions for how to remove these?
Have you tried inserting a screw in the opening of the pin and pulling it using the now attached screw as a handle? Or gluing it if screwing is not possible and then pulling?
