Before setting the bearing on a new soundboard it is necessary to fit the new pinblock to the plate, and to relocate the plate and pinblock assembly into the case of the piano. The plate and pinblock need to be not only in the correct position left and right, but must also be at the proper height on all planes.

Part of the restoration process involves recapping the old bridges. This is done by removing the original hard maple bridge caps and all the original pinning and notching. This process is complicated in the model D because the bass bridge is attached to the treble bridge. The laminated bridge body is constructed at the factory with plies of vertical maple being pressed in a caul to the "U" shape you can see in the picture. These pieces of maple are one continuous piece from note one to note eighty eight.
