Subject: Action Spread Measurements


I have started my first of several grands YC Brackets to replace......This one has had previous regulations to compensate for the expanding brackets issue. The hammer flange screws barely cleared the bottom of pinblock getting it out of the piano!

 At first I was very careful to remove one bracket at a time and install that new bracket before moving on to the next one .....but now, I realize that was not practical as the brackets have changed/distorted over the years and so has other relationship deminsions over the years, SO......

"Where do you find the measurements for action spreads listed?" 

This piano action  is from a WG57 (Weber) model and currently measures 114mm on both ends! (This is after I have replaced all brackets with the new ones.) Okay, tell me this way off??!!!

Thanks for you knowledge!
