Travis,
You're way ahead of me; all I have is plans from "Live Steam" for a calliope, and bunch of brass tubing I'm saving for the whistles. Been planning on this for 20 years or so, I'm not always the fastest guy around! Heck, I learned how to shift in a Model A, can't be too fast! (still have that A too)

Here is a photo of my original 20" Type 1 toroidal whistle prototype taken during the July, 1982 tests at the Greater Cincinnati International Airport. I'm wondering how many of you in the Greater Cincinnati/Northern KY area remember hearing these tests? This type of whistle could replace air horns currently used on ocean liners and aircraft carriers. Could you image a calliope using a tuned rank of these? You wouldn't be able to use it on a riverboat.

A toroidal whistle is the acoustical equivalent of a large phased array of about 30 high power steam whistles and is capable of very high output at relatively low pressure. The prototype was successfully tested in July, 1982 at the Greater Cincinnati International Airport and was heard over a large portion of Northern KY and Greater Cincinnati by producing a 70 dB radius of 2.5 miles at a frequency of 430 Hz. This was far in excess of what the warning sirens could do.
Dear Annie, Keith & gang:
I'm no musician but agree with you two on using the 'Great' or 'Swell' pedals on a fine pipe organ. A year or so ago I attended the commemmorative World War II ecumenical service in Notra Dame Cathedral, Paris. There was standing room only and all of the hierarchy in full vestments, representatives of the allies along with soldiers and veterans in uniform. When the young organist
