In an exceptional method used by Steinway for over a century, the inner and outer piano rims are bent into the shape of the rim as a single continuous piece. Before Theodore Steinway developed and patented this method in 1878, rims were made of separate pieces held together with joints. 18 hard-rock maple layers, each twenty-two feet long, are used to construct the rim of a concert grand piano. The layers are 1st coated with glue and stacked. The stacked layers are then glued into a single form of wood by bending on the rim-bending press, a giant piano-shaped vise.
