Center Pin Tool
The most notable refinement we’ve made to this familiar tool is in its smoothness. Typically this tool has unpolished steel rods that slide inside holes in the bare aluminum itself. That just means too much friction can develop and possible binding, even when lubricated. So you have to work that much harder, placing unnecessary stress and strain on your hand and forearm especially when repinning complete sets of parts. We’ve polished the steel rods and added bronze bushings for them to slide in. Because of the smoother non-binding operation we are able to use a lighter gauge spring for further stress reduction. Has a replaceable screw-in pushpin. Finish is black anodized aluminum to keep the metal from staining your hands during extended use. WNG logo is laser etched.

Damper Action Installation Tool Kit
Understanding that most piano rebuilders have little-to-no experience installing damper actions, Wessell, Nickel & Gross has developed a comprehensive set of tools and procedures to help them install a WNG Damper Action into any piano. The Damper Installation Kit includes a Damper Action Measuring Tool, a Damper Flange Rail Punch, an Under Lever Center Height Gauge, and a Damper Pickup Half Stroke Gauge. The kit is meant to be used with WNG’s Damper Action Installation Procedure, which is divided into seven parts and can be found below.

Damper Action Measuring Tool

This invaluable tool quickly and easily performs the following operations:
  • 1. Tells you if a WNG damper action will fit inside your piano.
  • 2. Helps you pick the correct spoon length for your piano.
  • 3. Gives you the correct mounting block thickness for mounting to the belly rail.
  • Damper Flange Rail Punch

    The WNG Damper Flange Rail Punch is perfect for marking a flange rail for drilling.

    Under Lever Center Height Gauge

    This tool allows the technician to effortlessly arrive at the proper underlever center height for the damper action.

    Damper Pickup Half Stroke Gauge

    The Half Stroke Gauge makes it easy to create a half stroke relationship between the height of the underlever center pin and the spoon pickup to the key.

Glue (CA Gel)
WNG recommends using its CA (CyanoAcrylate) glue for gluing hammers to its high performance carbon tube shanks and has worked hard to develop a glue that handles like traditional wooden glue that technicians are already familiar with—the methods and techniques required for attaching a hammer to a carbon tube shank using WNG CA Hammer Glue require little change for the experienced technician. WNG CA Hammer Glue is a gel and therefore highly viscous—it does not run when applied and fills gaps well. These properties make it ideal for conventional hammer boring and fitting techniques. The open time (when the glue is out of the tube and waiting to be used) and setup time (the time required for the glue to set after it has been applied) are similar to traditional glues and WNG CA Glue does not require accelerator. Additionally, WNG CA Glue is highly resistant to moisture, unlike traditional glues often used to hang hammers, making looser hammer heads much less likely.

Regulating Tool Kit

Drop Screwdriver

Unlike most drop screwdrivers, WNG's are intentionally made to be very short. This allows the technician to easily steady his hand on the shank flanges while regulating. WNG also offers two different versions of its Drop Screwdriver--one with a barrel and one without. The barrel helps to locate the tool on the drop screw, however, some technicians prefer not to have this barrel.

Balancier and Jack Regulating Tool

The handle and tool tip are the same on WNG's Jack and Balancier Regulating Tools--the only difference between the two are their lengths. The Jack Regulating Tool is the ideal length to reach in to the regulating screw on the jack. backcheck

Let-Off

The WNG Let-Off Tool allows you to adjust let-off button eye screws during a bench regulation. The tool's length is ideal for steadying your hand on the shank flanges and its tip is relieved so that it will not bind on the regulating screw. *Please note that the WNG Let-Off Tool is designed for setting let-off on actions that use an eye screw. It is not the appropriate tool for dowel regulating buttons.* backcheck

Damper Hook

Typically, piano technicians remove the damper to make the topbend--a process that is highly inefficient. When pianos are being manufactured, factory damper installer workers make this same bend while the damper is inside the piano, resulting is much less wasted time. WNG's Damper Hook enables piano technicians everywhere to use the factory's efficient method of making topbend while the damper is still inside the piano.

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.
