More than a dozen thin layers of select hardwood are laminated into a single solid sheet and gripped in a giant press for a minimum of twenty four hours. When the pressure is released, out comes the finished rim of the grand piano permanently shaped into one of the most aesthetically impressive and functionally perfect contours ever designed for so complex an instrument. Forming the rim is a vital step in achieving tone. For fine tone must begin with the stability of the piano framework itself. To assure a rock firm bass for the sensitive scale, the soundboard is glued directly to the inner maple rim then the heavy plate is bolted to it. The keybed, on which the action and keyframe rest, is made of clear spruce rails doweled together and mortised into reinforcing walnut end pieces. This type of construction eliminates the danger of warping.
