[pianotech] Key leveling

[tnrwim at aol.com]

Hi Jack Et al,
Have you or anyone else seen the key levelling system that utilizes a 
ong screw that goes down through the key button/key onto the back of 
he balance rail punching?  Turning the screw in or out makes the key 
o up or down.  I'd love to get a photograph of this for a class I'm 
eveloping: "Off Center Balance Rail Bearings" for PTG Institute

I have a customer with a Ludwig grand with this system. I sent a picture of that a couple of months ago. I don't have it any more, but I can take another pictrure the next time I tune this piano in April. I'll make a note in my data base to send you the picture.

>Hello to All,
>     This leveling  system was produced by J.  French just
before P. A. Starch bought them in the late 50s. When
Starck was bought by J. P.Seeburg. in the mid 60s was
when this system went into production.
>   It was indeed  presented  as the best leveling device
ever, by the  " Seeburg "  brochure.
>   Its  weakness was that after you leveled  the key you
then you often had to adjust the  standard  capstan..
>    At first I really liked the idea.  Then  actually using them
  was not so good.
>    Of course the very best " leveling device" ever,
was in the  " Bowen Henderson" grand of Boston.
It was a dream  to work with.
