Over on the Friend's site there was a discussion on a model that could hold up in the trunk of a car. I suggested aluminum but the general consensus was along the lines of a composite material? In order to survive up to 200 degrees there can't be any type of adhesive used as a fastener and I don't know of any composites that will hold up in the heat AND under tension from the strings...... my direction is a piece of 6061 aluminum bar stock with T6511 temper and that will hold up right nice to 330 degrees. The staples can be pre-drilled and driven in for a press fit. I'm going to bake the tail piece and head stock in the oven to ready them! (Select maple) I'm still looking into the tuners. It will be a modern board zither without a sound box but can be set on a tabletop to play. To be continued...
Awesome! I've thought about trying to build something like the sheet metal guitars you see. I agree about the composite. I've made modern longbows and they're cured at 180 degrees. If I remember correctly, the composite must be cured at the temperature you want it to survive. If exposed to a temperature higher than the curing temperature it will fail. I bought some carbon composite once and it was cured at room temperature and it delaminated from the heat of sanding on the belt sander. So I think you're on the right track friend!

Got a whole bunch of mistakes on this one but it will work! I had to reverse the staple board to get another set of holes to drive the staples into. Low RPM and the pecking technique worked great. I angled the tail piece so the instrument will set on three points for vibration transfer. I may see about incorporating nylon contact points there to keep it from wondering when it is strummed?
