Sectional ABS Didgeridoo Using Four Different Diameter Pipes (Key of F)

This didge is the first one I've made that uses FOUR different diameters of pipe. It drones in F and also toots in F...which makes me wonder if it could simply be "scaled up" to produce didges in C and D that also toot at the key note.
