<html>  <head></head> <body>  <DIV>Hi list,</DIV> <DIV>Tuned this new Hamilton grand at dealers just before Christmas. No big deal, not great ,but no real major problems. Went back last week after a prolonged cold snap here in the NE. </DIV> <DIV>Key dip was no more than 8mm and regulation was terribly off as you would expect.</DIV> <DIV>Looked under fronts and found about an average of 8-10 punchings under each key,also key height is off on several naturals.</DIV> <DIV>I'm open to any suggestions besides gasoline and a match to correct.</DIV> <DIV>My first thought is to redo height and dip and then regulate,but could this be a key frame problem? Humidity level has not been over 30% in this room.</DIV> <DIV>RU/UP</DIV>  </body> </html>
