A screw hole eh? Your best bet is a 1/8" hardwood dowel. Drill it out with a 1/8" drill bit first, preferably in a drill press, so that it's straight. That should do the job nicely.Seaners said:What is the best method to fill a drilled hole on a guitar? Wood filler? The hole would be covered after filling so no issue with looks, but would still like to fill it. We are talking a screw sized hole here.
