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.</STRONG></FONT></DIV> <DIV><FONT size=3><STRONG>    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. </STRONG></FONT></DIV> <DIV><FONT size=3><STRONG>   I'd say the new puncing  has a similar beneficial yet cumulative = effect much like to mating & hammers to & leveling strings</STRONG></FONT></DIV> <DIV><FONT size=3><STRONG>  I placed the green punching = between two pieces of thin maple & put a calipers on each side. The = compression with <U>modest force</U> would change easily as much as .030. The white new = punching only .010.</STRONG></FONT></DIV> <DIV><FONT size=3><STRONG>   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.) </STRONG></FONT></DIV> <DIV><FONT size=3><STRONG>  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.</STRONG></FONT></DIV> <DIV><STRONG><FONT size=3>  Think of the improvement in SOUND Baby!!!!!!!!</FONT></STRONG></DIV> <DIV><FONT size=3><STRONG>  I  noticed no change in = noise even though this is a pressed felt & not woven.</STRONG></FONT></DIV> <DIV><FONT size=3><STRONG> I immediately changed the entire set = & tomorrow or Friday I'll have a chance to hear & feel  the = whole piano.</STRONG></FONT></DIV> <DIV><STRONG><FONT size=3>  Regards</FONT></STRONG></DIV> <DIV><STRONG><FONT size=3>  Dale Erwin</FONT></STRONG></DIV></BLOCKQUOTE></FONT></BODY></HTML>
