Piano won't stay in tune

[Mike and Jane Spalding]

Hi Duaine,

If the reason the piano won't stay in tune is that the pins are too loose (you would know this from your tuning) then pin-block treatment (I try not to say "doping" to my customers) may be an appropriate remedy.  There has been some debate about the merits of CA glue vs. glycerine here on pianotech, you can find it in the archives.  Personally, I much prefer CA.  Better tuning pin feel, and doesn't destroy the wood.  For either material, it takes more than a couple drops.  You need to apply it until the wood won't absorb any more.  Verticals must be tipped, to keep the liquid from running down the plate onto the felt and strings.  WARNING!!  This is not something you want to do by yourself for the first time on a customer's piano.  It's a good idea to own an old piece of junk or two, for trying out new procedures.  Or, through your local PTG chapter, find someone willing to let you watch while he/she does one.

hope this helps,

Mike Spalding RPT
