I'm so proud of myself! I think it would be easier to design a new piano! It was a teacher's piano and she said that the dampers had never worked right - jeez-oh-petes - when depressing the sustain pedal, the bass dampers were an inch off the strings before the treble dampers lifted, and on most notes, the spoon engaged the damper lever right at the start of the key stroke - she also commented that the action was heavy. I know I didn't get it to concert-level accuracy, but the whole system ended up pretty darn functional and in the right ballpark. She gave it a try afterwards and remarked that it was now doing what it should.</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Arial">My question is this: how does one go about bending damper-head wires on verticals without trashing the hammer-butt springs - not that I disturbed a single one of course - but I can see the potential to do that.   ;-)</font></blockquote> <blockquote type="cite" cite> </blockquote> <blockquote type="cite" cite><font face="Arial">Terry Farrell</font></blockquote> <div><br></div> <div><br></div> <x-sigsep><pre>-- </pre></x-sigsep> <div>Jon Ralinovsky<br> Piano Technician<br> Department of Music<br> Miami University<br> 513/529-6548</div> </body> </html>
