So I listened to the sound of F-4 carefully, checked the dip , then changed to the new ones, checked the dip , played the note & the sound suddenly came together with more power and clarity than the first punching. The solidity under my finger was firm and sure.     Thinking it to be an anomally I changed back to the green ones. The Sound diminsihed & lacked focus. Well ,I did this a bout three times on the same note with the same result. I then checked a bass note f-1 with the same effect.    I'd say the new puncing  has a similar beneficial yet cumulative effect much like to mating & hammers to & leveling strings   I placed the green punching between two pieces of thin maple & put a calipers on each side. The compression with modest force would change easily as much as .030. The white new punching only .010.    Considering all this, since the key is where the power is generated  it needs to have a precise stopping moment. If not after touch can change to a depth of .420 even with an initial dip setting of .390 .(which is my preferred dip in Steinways whenever possible.)   Think of the distance in excessive jack travel especially on parts with a narrow window for jack movement & also it's effect on slowing repitition performance. With the white punchings a far more dependable dip /touch can be assured.   Think of the improvement in SOUND Baby!!!!!!!!   I  noticed no change in noise even though this is a pressed felt & not woven.  I immediately changed the entire set & tomorrow or Friday I'll have a chance to hear & feel  the whole piano.   Regards   Dale Erwin</blockquote></body> </html>
