Now the task is to make the outside of the back level before I start to carve it down to match the inside contours. I am doing this with a very old Stanley plane I found at the flea market. It needs proper sharpening, which I am working on, but I was able to get it sharp enough to bring the laminated sections down to pretty much level. The centre piece is actually the level I'm going for. I wish the others had been the same thickness but that's just the way I got them, and I don't have an electric planer.
As you can see, there are variations in the grain patterns. I actually wanted that for this guitar. Most builders go out of their way to get a consistent grain, but I'm going for a look that will evoke the feeling of an old style radio, which often made use of wood grain in a different way. As I progress with the back, I will simply add new photos to this post, as I did with the inside carving earlier.
