Instrument

Rim: Back Frame Solid birch mortised foot-piece. Solid birch soundboard lining. Grand-type maple laminated closing rim; unequaled verticle strength & stability.

Braces: POSTS: 5 FULL-LENGTH tapered solid spruce with a volume of 3,600 cu. in. (58,993cm3); assures that backframe will remain straight and consistent and stable tuning. Strategically positioned with bottom ends tenoned into birch foot-piece for positive vertical alignment. Spruce fill-blocks between posts at top of backframe capped with solid birch backing board for positive horizontal alignment.

Pinblock: Hexagrip patented design; 7 laminations of quartered hardrock maple stock. Grain symmetrically distributed at successive angles of 45° or 90° employing grain direction uniformly around the circumference of the tuning pin to provide the ultimate in pin grippage. As a result of this exclusive design, the tuning pin has smoother movement under torque, a more uniform retaining action for solid setting, and a piano which will hold its tuning longer.

Soundboard: Created like the soundboard of violins to give a free and even response throughout the entire scale, it is so constructed as to be 9 mm thick in the center and tapered to 6 mm as it approaches the rim and outer case before being DOUBLE CROWNED. This design permits complete freedom of movement, while acting as a homogenous unit to displace a greater amount of air, thereby creating a richer and more lasting tonal response. Close-grained, quarter-sawn Sitka spruce, a wood having unusual stability and vibrance under stress and vibration, is used exclusively for the soundboard.

Ribs: Made from durable, resinous sugar pine to assure strong and constant support of string down-bearing on the soundboard. Rib ends are hand-fitted into their mounting surfaces virtually locking in the important soundboard crown.

Bridges: Treble: Hard rock maple vertical laminations capped with solid hard rock maple; planed to prescribed height, graphite coated, drilled, and notched by hand for precise individual string bearing. Design defies splitting. Bass: Rock maple base, cantilevered at angle for maximum resistance to string pressure. Maple doweled, glued, and screwed to soundboard.

Scale: Overstrung; combination agraffe; Front AND rear duplex. Tension: 37,500 lbs. (16,875 kg)

Plate: Sturdy gray iron; filled, hand-milled, and sealed; bronzed and lacquered.

Tuning Pins: Premium blued steel with rust-resistant, nickeled heads.

Strings: TREBLE: Ten whole & one-half sizes from high-tensile Swedish steel. BASS: Swedish steel core wire wound with pure copper. Longest, pressure bar/bridge: 46 3/8" (118 cm)

Hammers: 12.5-pound (5.66 kg) premium wool top felt over premium wool under felt; treated to resist insects and moisture. Compression-wired to retain permanent shape. Hard birch moldings. Shanks from select resilient maple.

Dampers: Horizontal-cut premium wool for effective dampening. Maple heads for endurance.

Action: White, quarter-sawn maple parts are bushed with specially treated wool action cloth for freedom from friction. Parts are anchored in hard maple rails. Dependable, Direct-Blow design permits ALL parts of the action to lie above the brass capstan screws. Specially designed to respond 14% faster fortissimo & 6% faster pianissimo by using an exclusive combination of half-round balance rail bearings and strategically placed key leads.

Keys: Bavarian spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, delicately abraded ebonized sharps. Tough, durable Linden wood buttons reinforce keys over balance rail permitting maximum tonal power with every strike. Longest: 16 1/8" (40.9 cm)

Keybed: Made from planks of stable, quarter-sawn spruce. Horizontal planks are freely mortised together, while their ends are permanently mortised into vertical planks, presenting a vented system for humidity escapement while allowing for necessary expansion and contraction. Hand-milled to be flat and true correlating with keyframe for snug fit. Strong, rugged construction provides a solid mount for keyframe and action allowing for precise and prolonged action regulation. Thickness: 2" (5.08 cm)

Pedals: Heavy, solid brass. Soft, sustaining, and full sostenuto.
