I'm not sure how this will look after going through the ether, but this is the drawing I use. As you can (hopefully) see, my lines of measure are a little different than those given by David L. ddf Delwin D Fandrich Piano Design & Fabrication 6939 Foothill Court SW, Olympia, Washington 98512 USA Phone 360.515.0119 - Cell 360.388.6525 del at fandrichpiano.com - ddfandrich at gmail.com -----Original Message----- From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Brown, David Sent: Thursday, September 20, 2012 7:30 AM To: pianotech at ptg.org Subject: [pianotech] Action Ratio measuring Well, that is just me being unnecessarily thick! Every representation I had seen showed measuring diagonally from balance point to key front / capstan. Thank you , David. Can you do it this way because the measurement at the bottom instead of diagonally gives the same results? If we could also explore a little more- once the action ratio is obtained , my understanding is that it is inverse to strike weight, higher ratio drives lighter hammers better with fewer touch weight problems and vice versa?
