[pianotech] WNG Backchecks

[Gene Nelson]

Thanks Ed,

  The WNG hammer arcing jig puts the arc a little bit further back on the tail than the Spurlock jig. This should give better clearance of the hammers at rest position.
  best I can tell, that's what it's like working on pianos.

  <<<Just last Tuesday our chapter was treated to a great class on WNG Back Check installation at Piano Disk by Jerry Reiersen and Mark Burgett. I think it will be taught at the California Regional. 
  Yes I do have the WNG tail cutting jig.
  The ones that we put on in the shop, check and hold in the up and down direction exceptionally well. The catching portion of the buckskin is limited to not much more than the surface area that is cut into the hammer tail so there should be no issues with high checking and hammer grabbing the back check.  I have heard that checking can be made at 9.5mm. Looking forward to experimenting with this.
  Will be curious to know as more folks use them if the standard installation procedure will work on short and long keys equally well.
  Gene

      With a bit of clever mini-woodworking, you can probably add a piece of wood to the hammer tails.

      <<Appears to be my only option.


      Or, perhaps you can return the hammers for something with a longer molding.

      <<What hammer sets do you use? What is a typical overall length for note 25 top bass? My Isaac is 81mm and I need 83

        Hello list,
        While trying to get ready for installation of my first WNG Backcheck set I discover that my hammer set (purchased uncut, unbored & uncoved) is not long enough (especially in the upper bass)  to get the 25.4mm beyond bore distance. 
        Anyone else get a chance to work with these yet? Have similar issues?
        Gene
