Instrument
Rim
Made entirely from hard rock maple; 14 laminations; continuous
bent, both inner & outer form one single rim; unequaled strength &
stability. Thickness: 2 1/2" (6.35 cm)
Braces
3 solid spruce with a volume of 1,678 cu. in. (27,497cm3);
Spruce provides tensile strength with less weight. Maple dowels fasten braces to
rim & crossblock producing a single homogenous foundation upon which is
built the tonal component. Note: Treble bell is not required in smaller grands
of lesser tensions.
Pinblock
Hexagrip patented design; 7 laminations of quartered
hardrock maple stock. Grain symmetrically distributed at successive angles of
45º or 90º 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 8
mm thick in the center and tapered to 5 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: Solid rock maple mounted to cantilevered and splined base.
Maple doweled, glued, and screwed to soundboard.
Scale
Overstrung; combination agraffe; Front AND rear duplex.
Tension: 36,602 lbs. (16,471 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,
agraffe/bridge: 54 1/4" (138 cm)
Hammers
16.5-pound (7.48 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 dowels housed in inflexible seamless brass tubing to assure precise &
stable regulation. Exclusive single, combination phosphor bronze repetition and
fly spring provides constant crisp touch response. 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: 19" (48.3 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. Front center is crowned
contrasting the reverse-crowned action frame for snug fit. This design
intensifies key movement and prevents "slapping" during heavy playing. Large
maple dowel ends provide a solid mount for adjustable brass touch-regulating
screws. Thickness: 1-3/4" (4.45 cm)
Pedals
Heavy, solid brass. Soft, sustaining, and full
sostenuto.
