The springs are all the same age, and probably from the same batch of wire. So replace them all. John M.

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.
