DIMENSIONS
Length: 5′ 1″ (155 cm)
Width: 57¾” (147 cm)
Net Weight: 540 pounds (252 kg)
BRACES
3 solid spruce with a volume of 1,050 cu. In. (17,202cm3); Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim & cross-block producing a single homogenous foundation upon which is built the tonal component. Note: Treble bell is not required in smaller grands of lesser tensions.
SCALE
Overstrung; combination agraffe; Front AND rear duplex.
Tension: 32,332 lbs. (14,550 kg)
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.
TUNING PINS
Premium blued steel; rust-resistant, nickeled heads
STRINGS
Treble: Twelve whole & one-half sizes from high-tensile Swedish steel.
Bass: Swedish steel core wire wound with pure copper.
Longest: Agraffe/bridge: 45½” (116 cm)
HAMMERS
Premium wool top felt and under felt; treated to resist insects and moisture. Compression-wired to maintain permanent shape. Hard rock maple hammer mouldings and shanks.
DAMPERS
Horizontal-cut premium wool for effective dampening with maple heads for endurance.
KEYS
European spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, abraded ebonized sharps. Durable Linden wood buttons reinforce keys over balance rail, permitting maximum tonal power with every strike. Longest key: 19″ (48.3 cm).
KEYBED
Made from planks of quarter-sawn spruce. Horizontal and vertical birch planks present a vented system for humidity escapement. Crowned and reverse-crowned action frame gives a snug fit, intensifies key movement and prevents “slapping” during heavy playing. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Thickness: 1¾” (4.45 cm).
PEDALS
Heavy, solid brass. Soft & sustaining.
