(Even though he is a N.Y. Yankee)<o:p></o:p>             “You can observe a lot by looking (listening)”<o:p></o:p>             <o:p></o:p> It can sometime help to have the owner play the note(s) whilst you climb over under and around this thing. Touch – push – grab everything including stuff on the wall. <o:p></o:p> One client was remodeling and put an old metal medicine cabinet on the floor 10 feet from the piano. At the piano the noise WAS coming from the piano (Bosendorfer) .I stood away while she played and the noise came from behind me (the cabinet) <o:p></o:p>             <o:p></o:p>             Don’t take any case parts off at first. Hear the buzz then remove on part at a time. <o:p></o:p>             Occasionally the noise will follow a case part and you’ll have it.<o:p></o:p>             <o:p></o:p>             Recently I had a noise from a top stick at rest rattling against the plate as an example of a case part noise.<o:p></o:p> <o:p> </o:p> Over the years one of the most vexing was on an old Chickering grand. Turned out to be the back action mounting blocks that were secured to the belly rail with screws and washers. One was just a little loose and you would have thought the soundboard was coming apart from this noise.<o:p></o:p> My point here is it could be a myriad of possibilities .Think of it as treasure hunt and by enlisting the owner they will have a real appreciation of your efforts and ultimately your expertise.<o:p></o:p>             <o:p></o:p> Tom Driscoll RPT<o:p></o:p> <o:p> </o:p> </div> </div> </div>  </body> </html> No virus found in this outgoing message.
