<DIV>
<DIV><EM> The other thought is if you 'all are using acu-just =
hitch pins
</EM></DIV>
<DIV><EM></EM> </DIV>
<DIV>Not accu-just, but vertical, yes. My understanding is that the =
accu-just
are a bit different (been a while since I've seen one).</DIV>
<DIV><EM></EM> </DIV>
<DIV><EM>then the type of plate suspension system isn't all that =
critical as one
can adjust the bearing on the board without moving the plate, especially =
if the
plate was installed in a fairly reasonable elevation.</EM></DIV>
<DIV><EM></EM> </DIV>
<DIV>You would think. But you don't really want the string more than 5 =
mm or so
above the plate and you need it a bit off the plate, so you really only =
have a
few millimeters of up or down adjustment. So you really need to get the =
plate
very near an ideal height - the pins don't really allow all that much
adjustment. I find myself adjusting the plate height just as close to =
ideal as I
did before using the adjustable system.</DIV>
<DIV><EM> </EM></DIV>
<DIV><EM> If one is <STRONG>not</STRONG> using =
acu-just
then it seems to me using a plate suspension system has a greater
potential for functionality in adjusting downbearing after the plate is =
strung.
However. Even if an adjustable system is used with conventional hitch =
pins
the lattitude for lowering the plate has limitations. =
</EM></DIV>
<DIV><EM> The first being lowering the plate =
behind the
bass bridge. A small downward adjustment of the plate here can provide =
way more
bearing than is wise.on heavily tensioned bass strings, so the =
suspension
system is limited here unless bass string bearing felts .bars etc are =
readjusted
to higher location. Possible, but a bit annoying.</EM></DIV>
<DIV><EM></EM> </DIV>
<DIV>Well, speaking for myself, all the pianos I have put the adjustable =
plate
suspension system one also got a new soundboard. I find that I am =
usually
adjusting the plate upwards rather than downwards from the original
position - largely because of the increased crown of the new
soundboard.</DIV>
<DIV><EM></EM> </DIV>
<DIV><EM> Also an adjustment at the highest treble plate bolt =
location
also has limitations in <STRONG>any</STRONG> system, as I see =
it ,
the stiffness of the plate flange bolted to the block & the =
unwise
application of to much rotational stress on same if that highest bolt is =
forced
more than a small amount. Too much here induces a continual strain that =
may bite
back in some form.ie. broken plate ,block pulled loose. But hey =
small
amounts are often all that's needed.</EM></DIV>
<DIV><EM></EM> </DIV>
<DIV>Indeed, I think most changes are small. But here again, if you are
replacing the the pinblock, you don't have to exactly duplicate the =
original
placement if you are going to be moving the plate a tad. Put it where it =
is
needed and at the angle needed.</DIV>
<DIV><EM></EM> </DIV>
<DIV><EM> In my first encounter with using an =
adjustable Coleman plate
suspension system allowed me to apply much needed bearing on a piano =
that I had
miscalculated bearing load upon. That instance also required some =
shimming of
duplexes etc to get the desired tonal outcome in one section & =
dimish it it
in another & I'm happy to say in that instance it saved my behind =
& the
gnashing of teeth of course. The piano sounded grand? of =
course......</EM></DIV>

<DIV>I looked at his system a couple years ago at a convention, but I =
forget the
details now. How does his system differ from what I posted?</DIV>
