<BR><BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">Hi folks - inspected a Yamaha 1983 G-5 gray market. Nice piano, but I am
<BR>able to insert two business cards between the pinblock and the flange for
<BR>90% of its length. Is this common in this piano; are there any known
<BR>problems associated with it; has anyone noticed tuning stability problems
<BR>with this piano?
<BR>Thanks -

<BR>About 10 years ago I tried tuning a GH1 Yamaha grand with a lot of tuning
<BR>instability. It had a gap in the flange. Yamaha replaced the piano.

<BR>the tension, and inserted maple shims. Problem solved.
<BR>
<BR>But a gap doesn't always mean tuning instability. I rebuilt a '30 Wurlitzer
<BR>grand once, where the pin block was bad, but the piano was not unstable. When
<BR>I cut the new pin block to the old pattern, and placed it on the plate, I
<BR>discovered a very wide gap. I thought I had messed up. But when I put the
<BR>original block in place I discovered it was made that way.
<BR>
<BR>Ernie Juhn claims a block does not have to be tight to the flange. He claims
<BR>there are enough screws in the block to hold it in place. I am not sure if I
<BR>agree with him, but I do believe there can be a gap, and not have tuning
<BR>instability.
<BR>
<BR>Before you condemn the piano, let it go though a couple of climate changes,
<BR>and see where it goes. Then take it from there.
