In this demonstration I show how to turn a train whistle. The train whistle is actually four whistles inside one body. I will show how make a jig, either using a 3D printer or just from wood, that makes it easy to use the lathe to drill the four holes in the required positions. I will also show how to make a jig to help to safely sand a dowel into a fipple.
