Re: 3d-printed whistle head: strengthening lower octave

The finger holes line up only because you used the same pattern at different starting points. If you line these up window to window, or end to end there is a better context over hole placement vs size. Are your measurements linked to a spreadsheet yet? I tried to line up the windows (give or take a...

Re: 3d-printed whistle head: strengthening lower octave

Those look quite nice, and pretty unique, whic hsi also nice. One of my biggest thigns for wanting to maek a 3d printable / injection molded head is uniqueness. Making a whistle out of tubes like everyone else kinda always looks the same. Print quality is also nice. Did you have to use internal sup...

Re: 3d-printed whistle head: strengthening lower octave

The main factors I'm aware of which affect volume are window width and tone hole size - and thanks to cutoff frequencies there's a physical limitation as to how small those can get and still work. Is there another factor I'm missing? I'm actually pretty satisfied with my 3mm windows - but I want to ...

Re: 3d-printed whistle head: strengthening lower octave

So, my attempt to make the above head went really wrong, if fascinatingly so. I did my usual process of cutting the pipe a little long, doing a bell note calibration, calculating hole spacing/sizing, drilling holes with bits smaller than predicted, and then tuning the whole thing. This whistle is in...

Re: 3d-printed whistle head: strengthening lower octave

So, I went back into WI Designer and added an extra bore point, so now I have the block at -4, the labium at 0, the bottom of the taper, and the end of the whistle. The new design might look more like what everyone's been expecting: https://i.imgur.com/ZDsp3fSm.png I've also found that it's possible...

Re: 3d-printed whistle head: strengthening lower octave

Taking up more space ... makes the upper second octave more sharp. Having a little cave in the block or mouthpiece like in gens, feadogs, etc, will have an extra flat upper second octave. No spacer or cave will be in the middle. As I thought more about this statement, I realized that it makes a lot...

Re: 3d-printed whistle head: strengthening lower octave

You could do what makers do normally to adjust the space in the windway. Burkes, Reyburns, MK, Etc, all take up space by having the block on the inside continuing on the sides, and go forward as much as you need to, to adjust the tuning how you want. Taking up more space by having it longer makes t...

Re: 3d-printed whistle head: strengthening lower octave

I decided to throw caution to the wind and make a head with a longer window (5mm), a higher wall (5mm), a larger roof radius (1mm), and some extra block length (.5mm) - and I ended up with a head with a lower octave so solid it says down there right up to the point it jumps to the third harmonic (th...

Re: 3d-printed whistle head: strengthening lower octave

Gah, sorry, I made a typo - I meant to say I'm using A , not B (I haven't fundamentally redesigned anything since I made my original post - that head is still current). With the "Just D5" profile, with 4 bore points, the best error factor I can manage is 237, net error .01, deviation 3.74:...

Re: 3d-printed whistle head: strengthening lower octave

Wow, ok, that was way over my head. So, that section seemed to discuss the need to make the area right around the window narrower, but I don't think it touched on making the bore conical; indeed, figure 22.11 shows examples of a contracted "blowing end" with a straight bore, a conical bore...

Re: 3d-printed whistle head: strengthening lower octave

I've made a couple of new heads so far. The first one increased the roof radius to .75mm and dropped the floor radius to .25mm, and that helped some. The second one increased the window length to 5mm. That helped more, but it also introduced some "reediness" to the tone. There's a .1mm gap...

Re: 3d-printed whistle head: strengthening lower octave

My goal is to make a really quiet whistle for my ears only, so I'm trying to see just how small I can get anything related to volume - and my understanding is that windway height, window width, and hole size are the main contributing factors to volume. I'm not so much concerned with how hard it is t...

Re: 3d-printed whistle head: strengthening lower octave

A standard conical-bore tin whistle starts larger at the head and gets smaller towards the bell; and something I read (somewhere ...) claimed that the taper doesn't actually have to extend the whole length of the whistle, that just putting it in the head is almost as good; so it makes intuitive sens...

3d-printed whistle head: strengthening lower octave

I've been working on making a 3d-printed tin whistle head to put on a (c)pvc pipe, and I've been making good progress. I'm happy with the tone, and I can get all the way to the top of the second octave without the sound getting breathy. However, my lower notes are too weak and want to flip into the ...
