Grandson, Kaler, got a train set for Christmas, and I figured that he really ought to have a good four-note whistle to drive his parents nuts. So, after a little research, I found a workable plan and made a couple of them. Both whistles are made of popular, 1.5×1.5 inches square; one is about 8.3 inches long and the other, about 6.5 inches. Each has 4 half inch holes drilled to different depths down the length. The long one has holes of 4,5,6,7 inches, and the shorter whistle has 3,4,5,6 inches. After the side openings are cut, the holes are plugged with dowels. leaving about 1/3 of the hole open. The dowels are recessed into the opening about 1/8 inch and the mouth piece added. The recess allows the air to enter the mouth piece and be channelled to all four holes.
I just had to do a little art work on them….just a fine point Sharpie and sealed with poly.
The sound is wonderful on both of them, and I can hardly wait to give one to my grandson.
