Thanks. I've seen that page before. It's a general overview, not hard data on various shapes of carbon fiber lever handles (tube vs. solid rod vs. hexagonal or whatever), how much the length of the lever determines flex; no info. on how much of the flex is in the handle-to-head interface (the threads), how much play can exist between the tip and the tuning pin, what features raise the price to $400 when somebody else can make one for $200, etc. --David Nereson ----- Original Message ----- From: "Mr. Mac's" <tune-repair at allegiance.tv> To: <pianotech at ptg.org> Sent: Tuesday, February 01, 2011 8:34 PM Subject: Re: [pianotech] Carbon Fiber Lever (was Hammer Technique: was Q &ARoundtable) On Feb 1, 2011, at 6:10 PM, David Nereson wrote: > … The websites and ads for these levers give very little > data from any actual tests of flex or leverage, … <David, The Fujan site does offer quite a bit of data.
