[pianotech] Point of contact between capstan and wippen heel

[KeyKat88 at aol.com]

Greetings and O My!!
 
       Thank you SO SO much for this!  This explains to me why the hammer 
goes forward into let-off at different  "speeds'' / acceleration rates and comes 
back out (or forward toward the  player)  at different "speeds'' even in a 
piano, whilst every  regulation adjustment seems to be equal. 
 
THANK YOU
Julia

What  happens when the motion crosses the magic line is that the key lever 
arm  continues to lengthen but at a faster rate, while the wippen lever arm  
continues to shorten at a slower rate.  This would be true well beyond  the 
normal range of motion.
