"Perhaps that can be done DIY from an PVC pipe with an hot air gun or a gas burner to soften and shape the end."

When I used to make my own PVC didgeridoos, I would melt candle wax and then dip one end repeatedly into the wax to build up wax layers until it had the desired thickness and shape.

Twenty years ago my neighbor, a retired surgeon, made me a PVC didgeridoo and did the wax buildup thing - I still mostly play that didgeridoo. Years later my wife bought me a traditional heavy didgeridoo from Australia, but it doesn’t play as well; still, when I played at a friend’s wedding I used the Australian one because it looks better :-)

I had excellent results using a large section of black bamboo, though I forget the exact taxonomy (lako?). I meticulously beat out the segment walls, then with a rasp fastened to a long stick, filed down the ridges. After sanding, I finished it with oil based stain, which necessitated it living outdoors for a while. In the end it proved a fine primitive instrument. I gifted it to someone and miss it. I can attest to the therapeutic effects of mastering the didge.

PVC works, but the acoustics do seem superior with actual plant material. Certainly the feel.

Update: I used beeswax for the gob hole.
