My wife pulled a Maple quilt rack out of a dumpster the other day and gave me the task of fixing it. I have it about done, but need to find a way to pull some of the wooden plugs covering screws that need to be tightened. Some of them are set at the right depth, and some of them are pushed in to far. I do not believe any of them are glued. Any suggestions on how to remove them preferably without tearing them up as I do not want to refinish this piece as it does not need it.
