Features of the Renner Wippen
On fine quality pianos, this amazing action mechanism, perfected over 300 years, is made from all natural living material like fine woods, felt, and leather which depend on small action centers to precisely control their motion with specific tolerances that must also move naturally within the environment.
Designed for superior fine adjustments after initial rough regulations. Also prevents butterfly spring from wearing a noisy groove in the repetition lever.
Renner wippens feature precision machined regulation screw and granulated tensions for optimum regulation.
Engineered and hand adjusted at the factory for maximum strength and precision in order to ensure the most finely tuned and durable regulation possible.
Over the average lifetime of a piano, the piano keys may be played millions of times, activating the hundreds of small levers which transmit the energy from the finger of the performer to the hammerhead which strikes the strings, producing the sound you hear.
Unique design includes a large, easily adjusted surface with adjustment arm ribbed at the base and deeply inset for maximum regulation precision and durability.
The flexibility of this unique design allows accurate replacement of piano actions for those very special pianos no longer in production and for which replacement parts are not available.
The High Definition Flange will provide a more accurate flange seating on the many different flange rails produced over the years for both vintage and modern pianos, providing a more accurate transmission of power from the key to the string.
One of the little know secrets of Renner action parts is the use of a special wood called Weissbuche – Hornbeam in English – which is naturally air-dried and aged over several years.
