An Appenzell dulcimer (or hammered dulcimer) is a hammer-struck, trapezoid-shaped zither. The Appenzell region in Switzerland has a long tradition of dulcimer building. The project is a wonderful synthesis of traditional craftsmanship and computer aided manufacturing: According to the design of the dulcimer player Fredi Zuberbühler, we optimized the frame elements for a dulcimer with arched resonance body and prepared them for the CNC-production on the 5-axis-router. The tops are subareas of a cone with shifted apex and therefore only single-curved. The bent tops allow better resistance to the string tension and requires less frame elements. The project was realized in a cooperation of Werner Alder dulcimer making for the handmade detailing and finish and Bach Heiden AG for the CNC-production. |
