After the braces have been glued to the back, carving is done to remove mass while maintaining strength. I used quartersawn Mahogany for this purpose. The braces are rounded in the middle and sloped on each end where they will meet the sides.
The back is placed on the sides and marked where the braces meet the sides. Some of the kerfing will have to chiseled out to accommodate the sloped braces. When the fit is just right, it is time to glue the back. I follow the same clamping procedure using my homemade clamps.
After the glue is dried, I use a flush trim router to remove any excess overhang of the back. It is now getting exciting – I can start to imagine the sound this instrument will make!
