<x-tab> </x-tab>That's an
interesting thought and a possible resolution to the crisis but it
doesn't answer if anything could or should be done with a warped plate. I
may go back to the call I had last night at my own expense to see if the
glide bolt adjustment will work. I don't mind eating a little for my own
education. I still wonder 1) could this have happened some time after
manufacture and 2) If not, why was this ever sold in the first
place?<br><br>

I had this happen on a brand new BB Mason and Hamlin not so long
ago. I raised the glide bolts, and it slipped right out.
They'd been cranked WAY down, though I couldn't figure out why. The
keyframe was up about 1-16 inch higher than it should have been.

I hope this helps,<br>

<dd> I've never
encountered this before and now I've seen it twice in <br>
<dd>the same week. 2 pianos both from very different manufacturers and
from <br>
<dd>different eras coming in to my neck of the woods from 2 entirely
different <br>
<dd>climates and regions both have the same problem. I went to each of
these <br>
<dd>customers homes and for one reason or another found it necessary to
pull <br>
<dd>the action. (Sorry, both are grands). I found that the pin blocks
were <br>
<dd>touching the center 2 octave action screws and it was impossible to
pull <br>
<dd>the action as we normally due. I was able to pull off the stretcher
on one <br>
<dd>of these and found to my surprise that the pin block was intact. No
<br>
<dd>delaminations at all which is what I expected to find. Instead I
found <br>
<dd>after fishing out one of my most important tools (string) that the
plate <br>
<dd>was warped downward in the center by roughly 3/8" or 10 mm
pushing the pin <br>
<dd>block into the action.<br>
<dd> If any of you have
ever run in to this problem especially in a <br>
<dd>rebuilding capacity, what if anything have you done about it? I know
of no <br>
<dd>way to un warp cast iron so I suppose that's out of the question. Is
the <br>
<dd>piano scrap now? Is it possible that the warp happened recently and
did not <br>
<dd>exist at the time of manufacture?<br>
<dd> FWIW, one of the
pianos is a 70yr old (or there abouts) Henry F. <br>
<dd>Miller grand and the other is a 15-20 yr. old Schumann (Samick
product). <br>
<dd>The first actually has some potential to be a fine instrument if it
weren't <br>
<dd>for the warped plate. The second never was and never will be anything
but a <br><br>
