(or is supposed to) . 3 inches of flex says somethings really wrong. If it were me I'd be concerned. !877 is old. When you screw the tail down its going to put some torque on  the pinblock. It's possible its just a fluke warp but I recommend looking again carefully at every thing. Maybe it was sitting to high on the nose and strut bolts. Don't break any thing!!!! You're kinda of second hand information as you were't the original re whateverer person you're at a disatvantage as to some possiblr particulars.</BLOCKQUOTE>     Some plate flex is no real concern and usual but if the piano is getting a new belly I have the freedom to set it up with no plate flex at all.             Dale Erwin <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> Are we 100% sure the new pinblock sets at the original height and the top surface is at the original angle?

I am assisting a technician who has replaced the pinblock and board in a Steinway B. The frame has been out of the piano for about 5 months. As we are fitting it back in, it is not at all close to sitting tightly on the front or rear sections of the inner rim. If I clamp the front down tightly, the rear (tail) will raise about three inches (the new pinblock is exactly where the old one was). Is this normal? I was worried that bolting it down that much would stress the plate. Thanks. </BLOCKQUOTE> </HTML>
