I'm<br> assuming that the kind of differences in tone that a looser pin will<br> make are different then a shank with a soft spot causing an abnormally<br> low resonant frequency.  But, since I dont know more specifics about<br> what Chris was exactly getting at... I'll have to reserve further<br> judgement until I get a chance to try this out myself.<br> <br> Sorting by frequency ahead of time is indeed easier then sorting by<br> weighing.  And all this has gotten my head a scratch'n again :)... so on<br> the set of D shanks I'm about to weigh I will cross check just for the<br> sake of interest.  I have a set of weighed shanks ready to install for a<br> Bechstein B also... I can check the resonant frequencies of them and<br> cross check them as well. Should go fast enough.<br> <br> Most certainly tho... if Chris has demonstrated that pinning can effect<br> shank resonant frequency... then these are best sorted ahead of time. <br> I've heard of the adjustable friction flange... but never tried them...<br> so I cant speak as to how they work.  Perhaps Stanwood himself may chirp<br> in here.<br> <br> Cheers<br> RicB</font></blockquote> </blockquote> </body> </html>
