Hi everybody! 
I’m not a professional tin whistle maker, but I make tin whistles
I have a question. I would to perfect my whistles, and I make that with 5/8, 3/4 and 1/2 aluminium pipes, pipe cutting, cutter, sandpaper, etc…
What I need to perfect my whistles? Any Tin whistle maker there?
This is one of my whistles
My tweaked Generation D (I tweaked it myself )
Thank you! And help me please! PURA VIDA!
Welcome to C&F. Pardon my English, my Spanish is terrible. That’s a very handsome aluminum whistle you have there.
Yes, there are quite a few whistle makers posting here, including myself. I would suggest that you do a search on “whistle makeing” or “whistle building”. That should retrieve a lot of posts on the topic. You might just browse through the last few months of posts too. There have been a number of new whistle makers asking questions here lately. They will surely post to say hello. It is good to have another maker join the fraternity.
All sorts of methods and materials are used by the makers hanging out here. The tools you have described are the type most of us first used. I have gone on to acquire a lot of machinery to make whistles, such as lathes, drill press, buffers, grinders and so on. Enjoy!

Thank you!
Yeah! I have been thinking about professional machinery, so thanks for the list! I want to perefect my technique
It looks pretty good - do you have a record? 
Excelente whistle!! Luce realmente impresionante!
(Excellent whistle!, It looks really impressive!)
Thanks! What means “record”? the blow instrument played in the schools, or it means something more?
Sorry I need to learn speak English 
Gracias! que dicha! alguien que habla español!
Eso quiere decir una grabación (disco, CD). Algo que nos da una impresión del sonido de tu whistle.
Sí, “recorder” en inglés es ambiguo entre “flauta dulce” y “grabador”. Pero “record” como sustantivo musical indica siempre una grabación. 
I ment sound file But I saw this clip of yours on youtube - it sounds AWESOME! Are you gonna sell some whistles too?
Yeah! of course!

If you want to perfect it you first have to decide what’s wrong with it.
Then you have to realize that there is no such thing as a perfect whistle and decide which part of perfect you are seeking.
Looking at a whistle or listening to a sound clip is not going to allow anyone to decide its level of perfection. edit - by this I mean one has to also play it as well.
just my 2 cents
You’re right I think that the bevel of my whistles would have to be square and noncurved, like a susato.
Maybe what’s needed is a whistle tour. Then people could give you feedback having played one.
Very nice design! The photos are great.
I notice right away that the depth of the voicing window is a little shallow. This makes the labium ramp short. If you can use thicker material for the whistle head joint it would improve intonation. I also suggest thinner material for the whistle body. This will correct flatter pitch in the upper registers. Under the higher pressure of the upper registers, the air column forces itself up into deep tone holes and flattens pitch (more cubic volume used).
Thin Brass/Bronze tubing for the body can be found in most craft outlets and thicker tubing can be found in plummers supply outlets. If you want “Prefection” I suggest using a Lathe for tapered wood and metal designs. Tapered “Shell Augers” and a steady rest are used to make wood designs while “Metal Spinning” techniques are used to form tapered metalic instrument designs.
Do you want to “graduate” from found materials?
Very smart whistle!
Thanks for your advice! I send you a MP
Thank you!
