I am currently building a Low D (D4) whistle with 25mm OD tube. I have a commercial model to use as a reference, so it is going well.
My next project is an Alto F. Unfortunately I don’t have access to one. So I was wondering if anyone could either point me in the right direction to any online resources or give me some measurements. The first is, what diameter tube is your whistle made with? what is the overall length and a bonus but not strictly needed hole spacing and size.
Could anyone with a Low F whistle and a set of callipers or a ruler let me know what size tubing is being used for their whistle? Preferably the outer and inner diameter. I am trying to build one with 25mm OD/21mm Inner and the hole sizes are too big for my fingers!
3/4 nominal PVC (1.05 OD x .824 ID) works pretty well on my PVC models, but I do turn down one end and bore out another piece for the mouthpiece to reduce the windway height.
Mine is 7/16" diameter which is actually a little bigger than your 11mm. Out of curiosity are you trying to use your finger tips to cover or pipers grip using the middle joint flats? The piper’s grip may help you with covering those if you hadn’t been using it.
Thanks for your help. No on Low D whistles I use a pipers grip. I am just having a few problems scaling a low D whistle that I have to a alto/low F. Some of the holes are just coming out too big. I need to move them up and down the tube to get a comfortable finger span.
