After the bridges are glued to the topside of the piano, the bottom side is ready to be finished. The first step is to cut a radius on the top of the ribs. Then nthere is a lot od hand sanding in preparation to finish being applied to the underside only.
The surfaces of the board that will accept glue need to be masked off before finish is applied.
With the underside finished, the board is ready to be glued into the piano.
