From Pathfinder Wiki
Before drilling, glue an end cap on to the mouth end of the flute by applying PVC cement to the pipe (not to the cap). Once the glue has set, drill the mouth hole through the end cap. Then drill the remaining holes. Run a wooden dowel through the inside of the pipe from the uncapped end to knock off the burrs left from drilling. If desired, you can sand the outside with wet sandpaper while you hold the pipe under a stream of running water. See the note on the Pan Flute for precautions against PVC dust.
