"Dead Keys - Noisy Hammers"

[Paul McCloud]

            Check to see if the bridal straps have slid down the wire.
Baldwins had some wires that look like a snake at the tip, which
supposedly works to hold the bridal strap, but the strap slides down on
the wire.  If so, a spot of glue will solve this.   
            Also, see if the straps are hanging up on the tip of the
jack while it's being played.
            Hope this helps.

Hello,
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?
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?  
As an aside - the piano sat dormant for at least 30 years with no care
at all in West Texas.
Thanks
