How DO you regulate hammer = height and letoff in the grand piano? The method I learned is: Pull the action, = measure string height at the extremes of each section using a string height = gauge and a busines card; put the action on a nice, firm, flat surface (I = know that this is the place where errors creep in, if the keybed and the = work surface are not both quite flat); use a contraption to simulate = string height; and regulate hammer height, letoff, checking, drop, = etc outside the piano.</SPAN></FONT><o:p></o:p></P></DIV> <DIV> <P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT = face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"> <o:p></o:p></SPAN></FONT></P></DIV> <DIV> <P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT = face="Trebuchet MS" color=teal size=2><SPAN style="FONT-SIZE: 10pt; COLOR: teal; FONT-FAMILY: 'Trebuchet = MS'">In some situations I have had to do an on-site regulation where there is no = good, flat surface for the action, so I've tried to do it in the piano. I = can't see how you can do a good job with it. Feeding a hammer blow gauge = through the dampers, turning it 90 degrees and pulling it gently up to = contact the undersurface of the string, and holding it there while trying to get = an eyeball on the hammer surface from the front of the piano and using = the other hand to regulate the capstan ... difficult enough to do = samples but what a challenge to do them all that way. Very hard to get a good = line of sight over the hammer flange under the pinblock. So I have resorted = to approximating, measuring only a few, pulling the action into my lap = and eyeballing the tweeners.
