So some of my tuner screws are no longer tight but keep spinning when screwed in. I learned that toothpicks are perfect fill for the holes and will create a good bite for the screw. My first world problem and question is: should I used glue and/or drill pilot hole before installing the screw? 1. I see many do neither, and the logic is toothpicks are made of very soft wood. 2. I could argue the contrary that soft wood needs strenthening and thus glue would be a good companion. 3. Besides, since it's a snug fill, would that extra material be too much for the hole and therefore need pilot hole to be drilled just like normal plug and bigger screw would require? Many thanks for your thoughts.
