Thank's for all the contributions.
I will start with a small bore (12 mm).
And probably followed by a 16 mm version. Or I try a 12 mm routerbit on a depth of about 7.5 mm, which gives a somewhat more square bore, equal to approx. 14 mm diameter.
I will, in time, post the results.

So the smaller bores make it easier to play the second octave? But the bell-note will be weaker? Considering the available routerbits, I have the choice between 12 or 16 mm. I calculate the whistles with TWJCalc. Both diameters result in models that I can build in wood. So what would you advise? 12 ...

I mistyped, should have been A#
Corrected the subject of my own posts

I am talking about whistles.
And you are right about the C# etc.
The graph is a great help.
So thanks.

I want to make my own A# flute, in teak or purperheart. I have these at home. But I don't know what bore-diameter to choose. Native american A# would be 20 mm (3/4). But that seems rather wide in my opinion. I know smaller bores make overblowing somewhat easier. So would 16 mm be a good diameter? Wh...

I just filled up the hole beneath the flue on my Dixon DX005 Did that with epoxy-glue. Put some masking tape to cover the flue and the cutting edge, and dripped the epoxy with a small needle into the hole. Huge improvement. I am a starting tin-whistler, and now it's easier to get the 2e octave. Just...
