I don't agree with Grotian's sequencing method. I've been sorting low pitches to the bass end and high pitches to the top for over twenty years. One basic principle I follow is a low pitched knock associated with a movement within the piano reduces power. It is one of the main reasons I change front rail felt punchings. Hard felt punchings create a low knock that robs power from the sound. I find the same to be true with the pitch of the shanks. </div><div><br class="webkit-block-placeholder"></div><div>But as I have said before: to each his own. Grotian does it their way and that's fine. I know what works for me. </div><div><br class="webkit-block-placeholder"></div><div>Tim Coates</div><div><br class="webkit-block-placeholder"></div><div><br><div><div>On Feb 16, 2008, at 8:07 PM, Keith Roberts wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>My question is, if you are weighing the whole shank and flange, how do you know the distribution of the difference in weight?
