WNG Custom Back Action

SKU: 06-5802

What Options Should I Choose?

If you have any questions regarding what options to order with or how to order your damper action, please download the Custom Back Action Process instructions. You can specify a custom damper action by following these steps:

1) If you want WNG to supply damper heads and wires you will need to: - Establish the number of dampers in the piano. - Establish the number of bass dampers.

2) Determine which flange rail to use.

3) Determine Underlever Flange Types (with or without springs), Sostenuto Tab height, Spoon Length, and Leading Pattern. (Custom leading pattern available at extra cost).

4) Determine whether or not you wish WNG to supply a sostenuto rod installation kit. Please note that this costs an additional $75.00.

Can you drill and tap aluminum rails?

Drilling and tapping aluminium isn't difficult, but it is different than wood. You'll need aluminium tapping fluid, a 3.3 drill bit, and a M4.7 thread tap before you can start drilling. Please note that WNG does not include these materials with its damper actions. However, you don't have access to or can't find them, WNG offers them in a kit or you can buy them individually via the links below.

Do you need a scale stick?

To complete your order of an Assembled Custom Damper Action, you will need to send WNG a completed Scale Stick. For information on how to order a Scale Stick Kit and instructions on how to use it, please visit our Scale Stick page.
