Repetitions

The use of composite materials has allowed Wessell, Nickel & Gross to design a repetition with features impossible to execute in wood. WNG's heel locating system, integrated button, stop and optional rest cushion would not have been possible if the parts had been made from wood.

A great deal of effort has been put into lightening the repetition. A testament to this fact is its unusual shape, designed entirely for the purpose of reducing mass or shifting mass towards the center of rotation. By reducing the moment of inertia, WNG has reduced the dynamic touch resistance felt by the pianist.

It is important to observe that this design could not have been executed in wood.

The 99mm Standard

Wessell, Nickel & Gross repetitions can replace any repetition that conforms to the 99mm standard.

This means that the distance from the repetition flange center to the jack center is 99mm +/- 1mm.

Optional Rest Cushion

On most repetition systems the rest cushion is either on or off depending on the design of the molding upon which the repetition is based.

WNG has designed an easy choice into the system. You decide if the rest cushion is included or not. It's your choice.

Precision Heel Locating System

On the WNG repetition, there are 7 slots in the bottom of the repetition base.

On the heel, there is a corresponding tab that is offset thus allowing two different heel locations for each slot. These locations are referred to as A and B.

Therefore, there are 14 different heel locations available to the sophisticated rebuilder. These are referred to as positions 1A through 7B.

Reduced Rotating Mass in the Repetition Base

The unusual shape of the WNG repetition results from the design effort to reduce rotating mass.

- The main beam is lowered to reduce the size and mass of the heel.
- The balancier post is angled back to move the mass towards the center of rotation.
- The jack stop is molded into the base and angled back to move the mass towards the center of rotation.

Low Maintenance Repetition

Hard Bushings

Cloth bushings have problems:

- Cloth bushings are unstable in a changing humidity environment
- As cloth bushings change, center pin torque changes
- As pin torque changes so does the touch of the piano

In comparison, hard bushings are quite advantageous:

- Hard bushings are dimensionally stable as humidity changes
- When exposed to changing humidity, pin torque change is negligible
- The change in the touch of a piano is negligible

Test Results: After 18 million blows, pin torque exhibited virtually no change. In extreme environments, from 10% to 90% Equilibrium Moisture Content, pin torque was stable.

Wide Variety of Flanges

WNG provides appropriate flanges so that the composite repetition is able to attach to a variety of repetition rails.

The available flange designs are: Current Mason & Hamlin, Steinway, Aeolian Mason & Hamlin, Wessell, Nickel & Gross Classic, Renner Short, Renner Long, Knabe T1, Yamaha, and Baldwin.

Three Different Jacks

WNG provides three different jacks for interchangeability with many repetitions.

Standard Jack: Most commonly used jack in the world.

Modern Jack: Same as Standard Jack except with a low angle tender

Classic Jack: Same shape, length and tender as found on WNG Classic actions

WNG Sample Parts Kit

WNG offers a Sample Parts Kit to aid technicians in determining which parts will work best on a specific piano. The kit consists of several pre-assembled shanks and repetition assemblies that will fit most common piano brands and which can be installed on a trial basis. It also contains a variety of flanges, shanks, and knuckles so that a custom action can be built to match most pianos. With nine different repetition heel heights that can be placed in fourteen different positions, a technician has the ability to experiment with different combinations to improve the geometry of the piano action.
