PIN BLOCK 7-ply;cut from tenacious,quartered hard rock maple stock. Grain symmetrically distributed at successive angles of 45 degrees or 90 degrees 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. 7-ply;cut from tenacious,quartered hard rock maple stock.

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 homogeneous unit to displace a greater amount of air,thereby creating a richer and more lasting tonal response.

KEYBED Made from planks of heavy quarter-sawn spurce. 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 of constraction. Front center is crowned contrasting the reverse-crowned action framed for snug fit. This design intensifies key movement and prevents "slapping" during heavy playing. Large male dowels ends provide a solid mount for adjustable brass touch-regulating screws. Thickness:1.75" (4.45cm)     Made from planks of heavy quarter-sawn spurce.
