Update on the back - we finished jointing and joining the pieces today. We decided against the mahogany as it had some runout that we didn't want to deal with, so we used a piece of ribbon sapele instead.

Note that the photo is kinda upside down - the walnut is actually on the treble side, sapele on the bass side. The photo's not taken straight frontal, so it doesn't look right when you turn it around the other way, sorry.
Side note: I like this project, but if there has ever been one that didn't like me... this is it. First the walnut split - OK, we picked another piece. Then the plane jumped when it hit the maple and did a little touch down / take off trick resulting in about eight or ten really ugly gouges (a couple are still visible in the photo if you look closely). And about three other things that just spoiled the fun the whole time... :\
Anyway, I'm wondering about a couple things. One is the "pre-finishing". If you are going to feather the back after you put it on, I wonder how much work we need to put into getting a perfect polish before we send it to you. Also, I'm wondering how far down to take the thickness - it's about 2.2-2-6mm right now.
Another question is about the radius margin. Brad, you said 2mm all around is more than enough - OK, I believe you, but I would feel better with about 4 mm.
Finally, the braces. As I have said before, we can't really shape the braces without seeing exactly how they fit with the radius.
Let me know what you think.
