before gluing the two bookmatched pieces for the back and soundboard, the edges need to be sanded flat and square so the create a good seal down the middle. To do this, a fence is used to sand and square the edge that will be glued together.Sand until you cannot see any light through the joint when you squeeze the two pieces together. If there is any light seen on either edge of the pieces when they are connected, they will rock apart, literally.
