With the WNG Portable Piano Pounder, rebuilding shops, piano stores, and piano tuners who do action work can now produce a degree of stability and consistency in their work once only available to manufactures. The WNG Pounder is portable and easy to setup. It is compatible with any piano that has a standard head scale. Setup requires 1-1/2" or about 40mm of open space at both ends of the keyboard. The inputs go from 90v to 230v and boast 1,200 hits per hour!! As with all products on this site, the price listed includes FREE domestic shipping.
The Portable Pounder plays the keys vigorously in clusters, naturals-sharps-naturals, up the keyboard over and over at ff (double forte), right down into the punchings. Turn It on and off at will or set it to run for 2, 4, 6, or 8 hours by its timer. After removing the cheekblocks, clamp the end brackets in their place and clamp an addition clamp to the keybed in front of the action to prevent the action from walking. As a best use for rebuilder, regulator, or manufacturer (Mason & Hamlin now uses this Portable Pounder over its industrial one in the factory - much easier), install it at day's end and time it to run for 8 hours overnight in preparation for the next day's work.
the regulating rack
Letoff racks provide letoff for a section. Regulating Racks provide the entire strike profile and change its height as needed for the whole action.
Applying The System
The Setup and Order of Operations guides you step by step and the Laminated Protocols let you tick off steps as you go, so you don't get out of order or leave something out.
The Regulating Rack's rail has LEDs that illuminate both templates and action. The Hammer Hanging Jig has its own LEDa, too. And Lighting Rails come in four sizes to shine light wherever you need it.
