Key Prepatation - Hermann Kluge Gmbh in Germany specially manufactures Keys for the Charles R. Walter W-190 Grand Piano according to Walter specification. Front key bushings, balance rail key bushings, and the balance rail holes are carefully fitted with calibrated culls and lubricated by Walter factory craftsman. Keys are thoroughly evaluated for precise sizing before the weigh-off procedure is initiated.

Key Weighting - Precision key weighting is critical to the touch weight and responsiveness of the piano. Each key is carefully "weighed off" according to a specified procedure. A tray holds the exact weights used in the weigh off for later insertion into the key.
