[pianotech] key leveling system

[JWyatt1492 at aol.com]

Hello everyone,
 
   I think what Wem is talking about is the  "Bowen-Henderson"
system.  The adjustment screw was like a large grand drop 
screw and was located near and in front the center pin. The 
bottom  rested on a strip  of felt in front of the center  rail felt 
running the full length of the rail. the bottom of the adjustment 
screw rested on this strip of felt  
 
    I rebuilt a  1920's  "Bowen - Henderson''  grand with  such 
leveling system. Leveling the keys  was a dream. 
 
    I inspected the center pin holes in the keys and there 
were no excessive wear to be found.
 
    In appx. 1962  J. P. Seeburg   blought the P A. Starck Co. 
They made Spinets and Consoles.
     These Pianos had a screw type leveling system  also.
This was located at the back and beneath the key. 
     This was simply an inverted upright let-off  rail  and
 was adjusted with a standard let-off tool.
      
   The systems described above will be on display in our
Museum soon with original parts.
   
    As far as the factories doing this   " think a  moment "
  If this cost a dime (10 cents) to install in a key and there 
  are 88 keys and they build 10.000 pianos that year  ?????
 
  Money  saved        IS --   100 %  -- PROFIT.
If a Co. does not make a profit it sends it's employees home
 cease to exist  -----------------. 
           Is  there an amen  ?????????
