A full 2 1/2″ thickness of selected hard maple layers, laminated, cross banded and held with moisture-resistant glue, then held at a constant temperature and humidity for at least four weeks to ensure proper moisture content.
Pinblock
The finest quality Delignit pinblock is used to guarantee an extraordinary life expectancy.
Bridges
The bridges are hand made and pinned; manufactured of hard maple according to a special vertical lamination process with a high grade, quarter-sawn maple cap.
Sound Board
The sound board is made of clear, close-grained, quarter-sawn, solid spruce. It is varied in thickness by reason of acoustical design. The ribs are of select, quarter-sawn spruce graduated in width and thickness, and feathered for flexibility and frequency of response. Each rib receives a special individual crown for its location in the sound board structure. The ribs of the Charles R. Walter Grand are also unique in their method of being mortised into the inner rim. This process is individualized for each rib of the piano, producing the perfect balance of stiffness and flexibility required in every square inch of sound board. The exclusive sound board design gives a very even tone from low bass to high treble.
Strings
The treble strings and the core wires of the wrapped strings are of the highest grade music wire. The wrappings of the strings are solid copper wire. String length and diameter of inner and outer wraps are all carefully computed to achieve the very smooth inharmonicity scale so characteristic of all Walter pianos. The longest speaking length of the W190 Grand is 57 1/2″.
Action
The Walter Grand contains the finest grand action, custom made by Renner for the W190 piano.
