Where are you doing this experiment(s)?</blockquote> Im afraid you will have to back track a bit through recent archives...about two weeks back for the full story... but it is basically about a new touchweight manipulation scheme. New in the sense that it changes touchweight by manipulating the weight leverage of the action without changing the leverage with respect to distance or velocity. Small opposing magnets are installed on the key stick forward of the capstan and directly above on underside of the whippen. Together these function like a second (compressible)  capstan/heel. <blockquote TYPE=CITE>What kind of piano/action are you using?</blockquote> I am half way through my first full install on an August Forster small grand. It looks like the darn thing is working way beyond my expectations. I am finding no problem obtaining a range 12 - 15 grams of DW relief with no significant  (none yet) drawbacks. I can adjust down to about 3 grams if I want, or simply flip down the key magnets to remove their influence. You'll find some pictures in the archives, and I will be releasing a full pictorial and article in a month or so... that is unless I find some fatal problem with the idea between then and now. :) <blockquote TYPE=CITE>  Thanks, Dave Stahl  </blockquote> -- Richard Brekne RPT, N.P.T.F.
