<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Dave, The scary part is to think that if it was okay a month ago, it is possible that a month from now you'll have to go back and undo everything you just did.  Don't lose any sleep waiting for it to happen, though.  <G> I've had the happy experience of finding the action sloppy on a spinet with lots of lost motion, adjusting everything to specs, then needing to undo some of the work several months later because the jacks wouldn't slip under the hammer butts.  The lady knows it needs humidity control, but it's one of those families where money seems to be in constant short supply.

When I arrived at his home, I found that the piano was so far out of regulation that I felt obliged to look for structural damage in the instrument.  I have never seen a piano so far out of whack.  There was no cracked plate, no warped keybed(it has a metal frame under the keyboard), nothing out of place, no signs of anything broken.  The hammers were between 1/4 and 1/2 inch off the rail, and most of them blocked against the strings when played with a moderate to hard blow.  I thought of trying to raise the action bracket bolts(the ones they rest on on the keybed) to raise the entire action up a small amount, but they were as high as they could go without bending the nose bolts upward. I figured it was a humidity problem that had caused some swelling.  That's a helluva a lot of swelling, though.  I ended up having to turn the capstans down more than one complete turn, then re-regulate the let-off and the back checks.  It came out fine, but I am wondering why  this happened.  According to the lady of the house, it went from good to unplayable in about a month.  It was almost as if someone had given a toddler some tools and told him to go play with the action. Anybody ever seen anything like this in a really high quality instrument? Dave Stahl</blockquote> </html>
