I do understand your point of leads located closer to the balance rail (“further back”) more likely to produce a better feeling action than fewer leads up front. Isn’t this the real principle underlying Steinway’s accelerated action? It was my understanding that the underlying principle of the patent was two-fold, to have the leads as close as possible to the fulcrum, and to have the balance rail pin slightly distal to the center of the half-round, effectively causing the fulcrum point to shift proximally as the key rocks. What was accelerated was the ratio, in theory. Regards, Ed Foote RPT http://www.uk-piano.org/edfoote/index.html -------------- next part -------------- An HTML attachment was scrubbed...
