Johannes uses the drilling technique as a method for producing self-made didgeridoos and is constantly improving the methodology. His instruments are barely distinguishable from termite-hollowed didgeridoos. By drilling, it is possible to build didgeridoos without glue and to fully bring out the natural beauty of wood. Johannes' White Beech didgeridoos are among the most visually spectacular didgeridoos ever. In his chapter, he describes in detail how he builds and presents his self-made tools.

Very helpful for the ambitious didgeridoo maker (and for wood-workers in general) is Johannes' internet resource on felling timber according to the lunar calendar.
