<div>Doo day, All. Once, with restoration the 50 year old Grand Bluethner I= 'd get the some loose balance and front pins in the keyboard. I have Soviet=  many let-off buttons. I drilled widen the balance and front hole= s to deep of the one or two thickness of the let-off button and plug with e= poxy. After sanded and drilled new hole for pins. It was tight enough and h= ad not problem after, in regulating. I don't know How they are work no= w, because that Bluthner had purchased the officer of the German = Embassy  and moved, how he told, to the West Africa. </div> <div>With warm regards</div> <div>Timur Rizayev</div> <div>piano technician</div> <div>Mahidol University</div> <div>Thailand.</div> <div> <br><br> </div> <div><span class="gmail_quote">On 11/9/05, <b class="gmail_sendername">= <a href="mailto:Wimblees@aol.com">Wimblees@aol.com</a></b> <<a href== "mailto:Wimblees@aol.com">Wimblees@aol.com</a>> wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0= px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"><font face="Arial" color="#0= 00000" size="2"> <div>The action on a 50 year D is getting to the point where I've recommend= ed that we get a new one, but the budget just isn't there.
