<html><div style='background-color:'><DIV class=RTE> <P>Hello,</P> <P>I am new to repair and have a question.  I recently worked on a Baldwin upright with wire lifters.  Several of the keys noted by the customer played but would go "dead" after several strikes.  The jacks were not resetting.  So I replaced those jack springs.  Upon replacing the action (pain in the neck) we found several more "dead keys".  Question:  Is it ever necessary to replace all the jack springs on a piano about 50 years old?  Are there any good reading materials on this action?</P> <P>Also,  A few of the hammers seem to make a rattling noise when they hit the keys.  They seem loose but I can't tell and the noise happens when the strings are struck.  What should I look at to repair this problem?  </P> <P>As an aside - the piano sat dormant for at least 30 years with no care at all in West Texas.</P> <P>Thanks<BR><BR></P> <DIV></DIV><FONT color=#000000></DIV> <DIV></DIV></FONT></div><br clear=all><hr> <a href="http://g.msn.com/8HMBENUS/2728??PS=47575" target="_top">Play games, earn tickets, get cool prizes.
