Under the kind tutelage of fellow Gauge O Guild member, Ian Middleditch I have been playing with turning whistles.
First, I made a form tool from a length of 3/16 silver steel rod ( based it on a photo that Ian kindly sent me of some that he had made.
Once filed to shape the cutting end was hardened and tempered using my microflame (the last time I hardened and tempered anything was when I was at school).
Next I drilled out the centre to take a 0.8mm rod and then roughed out the larger top part of the whistle.
Then I used the form tool to create the final shape. It did create the final shape but I think that it would do even better on a slightly narrower piece of rod this one was 2.4mm and I think that a 2mm rod would create a better shape with this particular tool. In the event I touched it with the diamond file to finish it off.
I then parted it off and I took Ian’s advice and put a length of 0.8mm rod in the tail chuck and through the hole in the part so that it didn’t disappear into the mists when parted off.
Repeat the exercise for the bottom part and solder together on a length of rod with a 0.5mm spacer in between to create the whistle (I used a small piece of 20thou styrene with a hole and slot made in it to slip over the centre rod).
The nuts were added after the whistle was made up and are from microbore tube filed in a pin vice to a hexagon shape.
