LMS Whistles

[Stuart Davies 3Participant @stuartdavies3]

Dear all,

 

I am making a whistle for my 3.5″ gauge Black five and want to make one with an LMS type hooter sound to it. I have followed the directions in the Martin Evans book and have attached a chamber to a smaller whistle. I bought a 3/8″ dia whistle commercially built, and cross drilled a hole in the top near the end, I then soldered a linking tube to a 1&1/4″ tube which stands vertically at right angles to the small whsitle.This larger tube is 1&1/4″ long. The note I get is very quiet and has no focus to the sond at all.There is no ‘ring’ to the note. I’m wandering if anyone has built a similar whistle that has been successful that I could copy?

Hi Stuart,

I well remember the hooter type whistle from when I was young – very deep sound.

I think that you need a considerably longer tube to make that deep note – look at musical instruments that rely on a blast of air. Try to read up LBSC`s instructions for whistle making. I can tell you that he said to keep the end open with a tight fitting piston on a rod protruding from the end of the pipe, so that you can adjust the effective length to get the desired sound. You might also do well to test on steam, not compressed air.

Regards,

John.

I found this whistle site.

What I liked about this site was the practical and the science behind the design. Hope you find a way to correct the pitch for your own tube.

John, it seems that site address is non existant.
