Thanks, Ron; I guess I did think titanium was stronger. So it depends whether you measure by volume or by weight... In the bigger picture, I like the fact that this is a strong shaft. I really thought I might break the student lever I had; the flex in it scared me. --Cy-- ----- Original Message ----- From: "Ron Nossaman" <rnossaman@cox.net> To: "Pianotech" <pianotech@ptg.org> Sent: Wednesday, December 29, 2004 12:49 PM Subject: Re: Tuning Levers > >>I love mine from Michael Calahan (mcalahan@networld.com): solid >>(non-extension), titanium shaft (no flex), with a Coke-bottle bulge in the >>middle of the handle, and a ball end. > > > Cy, > You may not have meant to imply that titanium is stiffer than steel, but > just for the record - it isn't.
