model 2 six-hole flute in "B flat" (Bb)

result of the evolution of a prototype with the following characteristics

than the other B-flat model (in green, on a separate page):

-in 4 parts, to limit the size of the pieces:

longest part less than 220 mm

different whistle :

-result: more resonant sound (this may vary depending on the material)

-different alternative fingerings

-part in a circle to inscribe something

(in general, people put the low note)

Please note: for this model, the names of the parts to be printed end with "102".

addon-02-04-2024 :

a friend who plays the flute all the time, and who participates in musical sessions, prefers an older prototype of this model in B flat, and insists that I offer it online as well , being one of his favorite flutes .

• different mouthpiece, rather large and angular; please at least sand the edges a little if you insist on trying this model, probably less comfortable for some.

-it has a smaller gap at the bottom fingers which may be preferred; for convenience.

-the sound is less resonant.

this old proto has no round for inscription

all files in this model end in "old".

don't mix files, be sure to print one or the other, as the differences are significant and the tubes and whistles are not supposed to be compatible (no observations or tests in this sense have been made).

printing: print the connecting sleeves vertically if you like.

But it's advisable to print the tube with the clearance holes horizontally, as for the tube with the whistle.for good sound quality.

use fairly rigid materials; pla, "transparent" pla, etc...

quality good, bridge parameters enabled

post-processing, assembly :

sand and deburr where necessary (irregularities, traces of supports, etc.)

the blowing duct that allows air to reach the whistle must be kept clear.

If necessary, fold a small piece of sandpaper in half to stiffen it a little; and pass a few times through this duct.

if the parts have trouble fitting together, rather than sanding,

you can, with care, use a heat-gun

to slightly soften and heat-adjust a part before assembly.

gluing;

it's important to avoid any air leakage; this guarantees correct sound: use cyanoacrylate or epoxy.

For cyanoacrylate, you can apply it in two stages, with a brief pre-assembly,

if the quantity for the first application isn't sufficient.

you can remove any drips with a chopstick that you run through the inside.
