Have any of you tin whistle makers out there tried using an octave balancing wedge in a cylindrical bore whistle, as Doug Tipple does in his pvc flutes?
No, not seriously. I tried once to put a wedge in the mouthpiece of a high D whistle, but I didn’t notice much difference. I’ve never tried experimenting with different sizes and shapes, which is why I wrote “no, not seriously”.
This subject comes up every now and then. Here’s a recent one.

Yes,
I do in my brass low whistles and flutes.
My wedge design is a thin tube of brass that is cut diagonally and soldered inside the mouthpiece. The wedge is just below 3 inches long.
