Number of notes depending on model of piano.  = Then next group of notes to 2 div (1 degree).  Then the last group = to 3 div (1 1/2 degrees).  Lastly install the bass strings and set at = pitch to 1 div (.5 degrees).</BLOCKQUOTE>    Carl --with what device are you measuring with.

Grin.  --------- Carl   Carl, As I see it you've got your own stiky = wicket as most uprightswere designed to have little or no crown. Now what do = you do with the acu-just? I would opt for the baldwin spec on the upright = board ,which is as you say nominal.  Most uprights have little = crown(usually none) and little bearing and many still sound pretty good. It' a = mostly mass driven system or not much stiffness due to crown compression or = bearing load.    Best-----Dale Erwin</BLOCKQUOTE> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #0000ff 2px = solid; MARGIN-RIGHT: 0px" TYPE="CITE"> </BLOCKQUOTE> </BLOCKQUOTE></BODY></HTML>
