Hi Malcombebb,
Yes. The thing has crossed the boundary between cosmetic and music.
A ceremonial instrument was never intended to play.
I would square the ramp-edge to get a decent sound.
The wind-sheet created by the mouthpiece demands a flat edge for the vortex to form.
It is true the the wind-sheet has a slight curvature, but not that much.
But it is a lot of thinking and work to calculate the curvature from the windway exit to the ramp.
I would slowly reduce the curve with knife or file until a 2-octave sound appears.
After that, I would work on the height of the wind-sheet and how it spreads to the ramp.
Play with it. Then play upon it.
11 mm is difficult for the bottom notes - but achievable.
From the photo, a good instrument might be had from it if you can accept big pressure gradients between 1 and 2 octave.
Work with the curve. It's complex.
