[pianotech] Underlever Spring Tension Measurement

[A440A at aol.com]

Greetings, 
    I set the underlever springs by measuring several along the length and 
marking them with a spot of chalk after setting them to the appropriate 
tension. Turning the whole assembly upside down, I give it a slight up and down 
shake.   It is easy to then set the entire rack to the index underlevers by 
simply pushing the levers down a little until they also move the same amount 
as my guides. 
Regards,
