[pianotech] SnS rim screws

[Joe Goss]

Hi Del,
>From dry to wet the piano has moved. I would think that the crown would increase with that change.
I'm thinking the change might be related to the drying out of the wood, spacers shrinking allowing the plate to move down when the bolts were tightened.


The felt in hammers in dry  conditions seems to not have as much life to the tone

  It's more likely the relative humidity around the piano has changed thus changing the moisture content in the board thus changing the amount of crown. Happens all the time when humidity levels changes.

  Joe, it could then be possible that the plate was up off the supports and when you tighten the plate bolts you got the plate down onto the supports and thus the improved tone and down bearing.
