A narrow flue on such a big flute may make the overblow
situation more difficult. If you consider the other option of going
wider and keeping the flue extremely shallow with only a small (or
no) upper edge bevel, this may work. Where that edge is positioned is
the first culprit of the overblow problem.
If you use super-thin superglue on the flue floor, you can sand it
very smooth to reduce air-friction in the flue (and reduce back
pressure in a very shallow flue). Same with the bird base. A flue
twice as wide, twice as shallow delivers the same amount of air but
makes it work MORE efficiently, producing a louder output in volume.
