In the latest set of builds I am going to build a concert as a base for a number of experiments, aka, learning some new skills.
I thought I would try out some really nice curly maple I cut from a tree a fellow in the neighborhood took down. It has a really fine, even curl. My favorite kind of curly maple. It also (at least some chunks) has a little brown heartwood with a little bit of spalting (rot down the middle of the tree). When I got the back glued together, it looked so nice, that I was unwilling to cut it down to a concert size. Better to save it for a larger tenor sized instrument in the future, to save as much of that really nice curly grain as possible.
I decided to make the concert out of some curly ash (nearly the last of the stash) that is just concert sized. No wasted wood.
