Flutes are harder than they look, because the sound is created by air tumbling around the inside surface, so every little bobble can change the sound.
I've done several rounds of PVC drum making workshops, because the first was enough to show me how to do it, and I taught other folks. Extremely forgiving media, although we do pay the provider to cut the pipes to length for us -- the original workshop had hacksaws.
