	One of my favorite subjects is whistles and I am happy to have a request to write something about them. To me, the whistle is a very important part of a locomotive. I would never think of building a loco and leaving off the whistle. That would be like omitting the fire or one cylinder or some other vital part. All of which brings us to the "crux of the mux", or something, and you can easily see what caused me to make a whistle for one of our great living musicians, [http://en.wikipedia.org/wiki/David_Rose Dave Rose]. It wasn't that I know so much about whistles, (note first, <i>important</i>, word in our title) rather than his poor locomotive was speechless! While I was giving it a general overhaul and pair of goat glands someone, namely Dick Jackson, dropped in to view the proceedings and hit my weak spot. He said that, "Of all the Live Steamers, I shouldn't be the one to let a loco go out of the shop without a tooter."

	The throat disc and pipe connection are turned from round brass. Rough out approximate shape, drill the center hole in the end and cut to accurate length. Any scrap of flat brass 1/4" thick or more and large enough to plug the tube will do for the other end. Neither of these will need pinning. Just clamp the partition assembly in a vertical position in the vise and sit the ends on for soldering, be careful with alignment, of course. Clean up and drill a center hole in the end drum and you are ready for the lathe work.		The throat disc and pipe connection are turned from round brass.

	Hold the throat piece in the three jaw and use a tail stock center for the other end. Rough turn over the entire length to near diameter for a press fit in the tube. Then finish turn the end next to the tail stock. Half the length may be finish turned at this setting. Then reverse the work in the lathe so that the throat is next the tail stock and complete the finish turning. Diameter of the throat disc is most important here. This governs the size of the throat opening. Tolerance for this opening is shown on the drawing and applies to all scales.		Hold the throat piece in the three jaw and use a tail stock center for the other end. Rough turn over the entire length to near diameter for a [[Press fit\|press fit]] in the tube.

Then reverse the work in the lathe so that the throat is next the tail stock and complete the finish turning. Diameter of the throat disc is most important here. This governs the size of the throat opening. Tolerance for this opening is shown on the drawing and applies to all scales.

	Remove from the lathe and clean up with a fine file. The slight difference between the two cuts as taken from opposite ends can be filed smooth, although in most cases it will not be enough to cause any harm. No increase in diameter is to be allowed for the press fit. The innards will fit right enough if machined to the diameter of the inside of the tube. In fact I generally turn this part one thousandth smaller, but must advise you that it may lead to the extra job of having to soft solder the two sections together in the event that you do not get a snug fit.

	I doubt if you will have a press large enough to push the two parts together. My whistles are persuaded along by aid of a large rubber mallet such as is used for automobile tire work. Hold the tube in your hand. Press the vanes in by hand as far as they will go, throat end first. Then still holding the tube in your hand drive it into position with the mallet. If the fit is tight a little oil will help to lubricate. It may be necessary to use a block to hold the tube in the final stages of the struggle. A short length of pipe is good for this. Put it in the lathe and bore it out a few thousandths larger than inside tube diameter then counter bore for about 1/4" depth to outside tube diameter so that the tubing will fit in snug but not tight. Be careful to have the pipe long enough to avoid having the throat strike bottom. When all is pressed together the tube end should be 1/2" from the face of the throat disc. If the facing of this disc became distorted due to heat while soldering or otherwise blemished it may be re-faced by use of a cut-off tool while held in the lathe as before. Only the outer edge needs facing.		I doubt if you will have a press large enough to push the two parts together.

	So, as I said before--fools jump in! Now Dave has one of the oddest Royal Scot locos in the world. It looks as British as ever and still eats Welsh coal from England, thanks to [[Lester Friend\|Les Friend]], but has a voice that is definitely American. I will not list the four notes used on Dave's whistle because it is nice for him to have his own special tune. The information contained here will enable you to select something of your own choice. I never make two whistles alike; for one thing, variety is too interesting.		So, as I said before--fools jump in! Now Dave has one of the oddest Royal Scot locos in the world.

	The chart gives you notes in the scale and their frequency along with the proper length of stopped pipe to create them. If the pipe length is doubled the same note will be derived, only one octave lower and vice-versa when the pipe is halved. An open pipe must be twice the length of a stopped pipe for the same note.

	: For those that choose to use these drawings, beware that the note charts given for chamber lengths are totally incorrect. Both Nelson's and Bagley's charts were drawn based on using air and not steam. Therefore the chamber lengths are off by as much as 4.5" on the low side (middle C) and 2" on the high side. Nelson's also shows a list of SP whistles that never existed. He says they came from Bagley. I've always been a little perplexed as to why they published these charts but it is what it is. Just a little tip from someone who's been there.
