John began the evening rather unusually by apologising in advance for the failure of his intended project. It seems 9 out of 10 whistles do not! John also mad ethe point that he does more preparation than my be strictly necessary (possibly because so many fail). So to start John puts his blank through the thicknesser and produces a 1” square piece about 5” long. Next he cuts a “fipple”. This is a triangular slice acroos the blank about ¾” from one end and about ½” deep and ½” wide. At this point the blank should look much like the (not to scale) drawing. Next mark the centre point on the fipple end an put the other end in the chuck and the centre into the mark. Turn to the round.
Next drill a 9mm hole in the fipple end about 2” deep. The length of the hole determines the eventual pitch of the whistle. Note the fipple should reach into the drilled hole. Insert the centre back into the hole and turn the mouthpiece shape to suit human lips. Mark along length of whistle to ensure parting cut is past the end of your drilled hole and
part off. The final element is the cut a piece of 9mm dowling about in half just long enough to plug the mouthpice of the whistle. Glue this in place, wait until the wood dries and test. I am very happy to report that despite his fears John’s whistle did.
