I'm in the beginning stages of having a custom built and had my mind set on a spalted maple top cap. However, my luthier (DP custom - no I don't care what you think about his work) sent me a piece of spalted maple because he wanted me to be aware of how fragile it is. I've got to say now, that I'm really hesitant to use it. I was able to snap it along the grain with minimal pressure between my thumb, fore, and middle fingers. After snapping it about 4 times, the individual pieces' edges were really soft, and spongey, like cork, or that wood for a toy wooden airplane/glider (see attached). Has anyone had any negative experience with spalted maple as a top cap? Any advice on an alternative? I love how it looks, but don't want to risk the integrity of the instrument. He did say that he could use some techniques in the finishing process that can "firm it up" if I want, but somehow that seems less than ideal. Help?
