I made the mistake of trying to remove a Schlage lockset with a regular screw driver too many times. (The knob makes it impossible for an ordinary driver to seat properly on the Phillips screw head. So every time I touch it, the screw heads get worse.) Now I've stripped both screws.
I installed the door knob in the main entry two years ago, and it gets a lot of use. I originally attached the screws with threadlock because I was so fed up with re-tightening them every few months. I was expecting them to be a bit stiff. But since I was the one who put the thing together, I thought I could just carefully back it out. It got it off once, but not any more.
So I wised up (a bit) and bought a $3 offset screwdriver, but the screw heads are too worn. The offset driver just slips out of the heads no matter how tight I grip it, and I've cut both hands trying to hold it steady.
I tried setting up a screw extractor, but the knob prevents me from drilling through the center of the screw. I also tried tapping the handle-end of a flat head screwdriver, with the flat head tip placed on the axis, to try and get some counterclockwise rotation, but the threadlock seems to prevent any movement.
Unfortunately I may have to completely destroy the lockset to get the thing off, which seems like a complete waste, but I'm running out of ideas. Is there anything else I can do that might remove it, without losing any more blood?
