Source of brass treblet tubing as used for making a whistle.

[Dave WoottonParticipant @davewootton]

I've always been useless at making whistles, but suceeded following a design from M.E that is fully machined from brass, it was described in M.E in an article " Jupiters Whistle" and I think the authors name was Olds, would have been early 1980's at a guess . mine is quite small and shrill but the steam gap is adjustable and it is easy to tune, the size can be varied , the longer the bell part the lower the note. I used an electronic tuner, had a photocopy of the article but just tried to find it and afraid I can't.

No soldering required!

Thinking of the material, I doubt the choice of metal would make much difference because the sound is produced by the vibration of the air, not the wall . I believe (cathedral-size) organ pipes are made from a fairly soft alloy rather like pewter.

The advantage of brass over copper is that it is tougher for the diameter and thickness.

Comparing metal to wood-wind is different as wood is somewhat absorbent, and that probably according to frequency so affecting the harmonics that give the instrument its timbre.

Incidentally, somewhat tangentially to the thread but having mentioned organ pipes, it's well worth exploring the web-site of organ builders Harrison & Harrison, for a fascinating and very informative stills-gallery showing these huge and very complicated instruments being built. Including making the pipes. I had imagined it nowadays all CNC and synthetic materials, but no; whilst individual parts might be made like that the assembly, in the firm's very up-to-date factory, involves considerable, highly-skilled manual fitting; a lot of it in wood.
