[pianotech] Schaib-Arendschein Grand Action

[JWyatt1492 at aol.com]

Hello Pat,
 
     Yes I do.  This type of grand action is a  single 
escapement.
   
    Regulate it the same as a standard vertical  action.
That is the hammer shank on hammer rail with a 
tad of lost motion. Let off and blow distance the same.
 
   Thayer Action Co. built all of the " Staib " ( Grand  )
actions.
 
   On the Foundation page in a recent Journal you will 
find a picture and a short commentary on this action.
M. Schultz used this action also along with other
Piano Company's.
 
   It worked well ( as a single escapement) action.
 
 
Regards  
Jack Wyatt
Dallas
