Spare ribs

The ribs are now on the soundboard, and all that remains to do to the soundboard before it's ready to install is to cut the rose hole. The ribs (the horizontal bars pictured below) help to stiffen the soundboard and keep it steady under the tension of the strings, and the cutoff bar (the other bar, diagonal to the ribs) defines the sounding areas of the bass and treble. First I glued them to the underside of the board, using go-bars to provide vertical pressure:



After the glue dried I scooped out the ends with a chisel, which is traditional.
