Remove the stack, replace the keys and Voila! the perfect key bedding ...</font></div> <div><br></div> <div>Will,</div> <div><br></div> <div>I've been doing the bedding process this way for many, many years. Not certain when or where I picked it up. Just know it's gives great access for any necessary adjustments to the glide bolts and the stack gives enough weight as you say.</div> <div><br></div> <div>However, I don't set the glide bolts with the newspaper pull approach anymore. Gave up on that a long time ago. I use the method outlined in the Steinway manual. It's works perfectly, and it's never failed to give an excellent bedding on any brand grand that I've experienced.</div> <div><br></div> <div>So maybe it should christened the YamaStein? or Yamaway? or Steinaha? or SteinYama? or Wayaha? or AhaWay? Method   :-)</div> <div><br></div> <div>And what Ed Foote says about the feet of the stack not always contacting the keyframe is paramount. I lightly glue in place balance rail shims to take up any space that might exist. Makes for a really solid contact!</div> <div><br></div> <div>Anyhow, there's valuable regulating & voicing information in those manufacturer technical manuals. And one of the great places to pick up some of those is at the Big One in Dallas this summer.</div> <div><br></div> <div>http://www.ptg.org/conv/2003/</div> <div><br></div> <div>Keith McGavern</div> </body> </html>
