Hey, just an idea while you were talking about the screwdriver and not having a long enough bit for it. What about finding an old screwdriver somewhere cheap and removing the handle? Then you'd have a longer piece that you could put in your drill. With the hole that was drilled too big I wonder if you glue like a stick in there of some sort and then redrill it if that would work for you. You did a great job at putting that new cabinet together the one that you made. It looks great.
