Installing the Tuner Piece

On the side where the string hole was made 3.5" from the end of the pipe, another hole was drilled 90 degrees around the pipe. The shaft of the tuner was put in this hole, and the piece was screwed into place using a wood screw that came with the tuner piece. This tuner piece is used to tighten or loosen the guitar string, adjusting the sound the string makes when it is strummed.
