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.<o:p></o:p></spa= n> </div> <div>   &nbs= p; 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. <o:p></o:p> </div> <div>   =  I'd say the new puncing  has a similar beneficial yet = cumulative effect much like to mating & hammers to & leveling = strings<o:p></o:p> </div> <div>   = 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.<o:p></o:p> </div> <div>    = 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.) <o:p></o:p> </div> <div>   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.<o:p></o:p> </div> <div>   Think of = the improvement in SOUND Baby!!!!!!!!<o:p></o:p> </div> <div>   I  noticed no change in noise even though this is a pressed = felt & not woven.<o:p></o:p></spa= n> </div> <div>  I = immediately changed the entire set & tomorrow or Friday I'll have a chance to = hear & feel  the whole piano.<o:p></o:p> </div> <div>   = Regards<o:p></o:p> </div> <div>   Dale = Erwin<o:p></o:p> </div> </div> </body> </html>
