August 2007 Piano Technicians Journal is public for those who read it! 5 page article by Barbara Richmond with Darrell Fandrich, Ron Nossaman and John Rhodes I've read some accounts of adding mass and those procedures have not been made too public yet, but you can experiment w/small vice grips on the back bridge pin in various areas to see if adding mass will do anything to enhance the sustain. Sometimes it filters/or dampens. Some people attach weights to the back of the soundboard/ribs and some move the treble wires aside, drill out the bridge, instert a small weight, and then cover it over...replace the strings. You need to be sure, that where you put them does not damage the bridge, or contact the strings. Several in a line, increasing or decreasing, depending on where you go. Someone really needs to get a proper procedure written up. Maybe they have. There probably is an "order" of preference as to which mods you should do in which order. Others can speak to that. Just throwin' some ideas out there. Richard Adkins Coe College -------------- next part -------------- An HTML attachment was scrubbed...
