Dulcimer String Anchor Pins
Instruments- discuss specific features, luthiers, instrument problems & questions
I would think that eventually the hole will elongate from the tension of the sting pulling the ball end into the wood. The pin holds the ball end in place away from the wood. However I am not a luthier...
I thought the same when I first tried it Don, but since then I've made perhaps 50 dulcimers using this method and it works perfectly. I wouldn't want to try it on softwood though. This is what it looks like with the strings in place.
