 | | The most important thing here is that the windway have approximately the same height all the way along, and that, looking through the bottom end of the pipe, you be able to see a *small* crack of light through the mouthpiece. |
 | | It's a bit tricky when the fipple is sticking out the end of the tube by a few inches, but holding the whistle sideways, like a flute, and covering the end of the mouthpiece with your mouth, it should be possible to sound a note. |
 | | So it seems better to make the fipple so that the windway is quite shallow, and then steadily strengthen the tone by sanding it down, until it plays where you want it. |
