The touch is on the heavy side, but not unplayable. Even though everything works "right", on soft blows, the jack isn't going back under. The keys are eased, the wippens and not sluggish, the hammer flanges are not tight, and the jacks return when the keys comes up all the way, and  But on a medium fast repetition, the jack doesn't come back under, and the hammer butt gets caught on the back check.  Would weakening the return springs help this? Or is there something else I should be looking for. </SPAN></FONT></div> <div> <div class=MsoNormal><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">Willem (Wim) Blees, RPT<FONT color=navy><SPAN style="COLOR: navy"></SPAN></FONT></SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">            </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Wim,</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"> The late great Steve Jellen addressed this in class. A too strong hammer return spring can overpower the returning jack. I would first check the jack pining, jack springs and condition of the butt leather and smoothness of jack tops. Also having the hammers check closer to the strings can give the jack more room to return. Capstan-whippen cushion friction and maybe even spoons digging into the damper levers could be worth a look. </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">A thousand years ago I was stocking up on all sorts of supplies and theorized that “heavy duty” and “heaviest -strongest “   had to be the best choice for everything.</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I think some20of those springs are still kicking around the shop.</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Best,</SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Tom D.</SPAN></FONT></div> <div class=MsoNormal><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"><br> <br> </SPAN></FONT></div> </div> </div> <br> <div><FONT size=2>No virus found in this outgoing message.<br> Checked by AVG.<br> Version: 7.5.524 / Virus Database: 270.8.0/1722 - Release Date: 10/13/2008 7:50 AM<br> </FONT></div> </div> <div id='MAILCIADA018-5bb048f4d38e2a2' class='aol_ad_footer'> </div>
