soundboard on my 1890's Knabe upright

[Fenton Murray]

1890 Knabe upright, ummm, might have been too difficult to remove the plate during the restring ( not rebuild ) which is why the cracks were not shimmed. The cabinet was built around the case on a lot of those. The low tenor is often a problem, grain run out on the bridge there is common (ESPECIALLY on Knabes) and I've seen bridge roll and a loss of bearing in that area. It's not really a recording piano, more money than it's worth to do right. Might have to live with it, Daniel.

  Daniel, 

  It sounds as though the "rebuild" did not include a new soundboard?  Anyway, if you like the sound and it's not buzzing, just let it be.  No, you can't shim from underneath, you would need to de-string remove the plate and shim the cracks. A lot of work, especially for an upright.  Then again, if it starts to buzz, then off to work you go if you think it's worth it! 

  My 2 cents

  hey techs 
    
  i've got a rebuilt (rebuilt 2 or 3 years ago) 1890's Knabe upright. nice warm, woody sound, and it's already been used in a few recordings. i'd like to have it sound nice for many more years. i do have one concern. i've noticed a crack or two in the soundboard, and it bums me out to have a rebuilt, beautifully sounding piano with a crack in the soundboard. 
  now i did a few shims at nbss on grands we were rebuilding, but never any uprights... and in the following post https://www.moypiano.com/ptg/pianotech.php/2006-January/184497.html, David Ilvedson says you can't shim from behind. 
  so my question is can anything be done to fix the cracks? 
    
  as always, any help is greatly appreciated. 
    
  thanks
