This is a picture of my first ever diddly bow. It was constructed from ash and is primarily made using an axe with a little help from a saw and a knife. The axe is even used to drive the tuning wedge. Can you tune your instrument with an axe?
I set this up at a recent bush craft training weekend (which was, as ever, an excellent weekend). You can tell I was listening to the training because I identified the tonewood used to make it by the fungus growing on it. This is not a recognised techiniue for identifying a guitars tonewood!
