<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>
