<DIV><FONT size=3> I have several comments about this. First when yo=
u say
drive them back in, I'll presume your not using a hammer? right?
</FONT></DIV>
<DIV><FONT size=3> The other thought is if you 'all are using acu-ju=
st
hitch pins 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. </FONT></DIV=
>
<DIV><FONT size=3> If one is <STRONG>not</STRONG> us=
ing
acu-just then it seems to me using a plate suspension system has a gre=
ater
potential for functionality in adjusting downbearing after the plate is stru=
ng.
However. Even if an adjustable system is used with conventional hitch pins
the lattitude for lowering the plate has limitations. </FONT></DI=
V>
<DIV><FONT size=3> The first being lowering the plate&nbs=
p;
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,&nbs=
p;so
the suspension system is limited here unless bass string bearing felts .bars=
etc
are readjusted to higher location. Possible, but a bit annoying.</FONT></DIV=
>
<DIV><FONT size=3> Also an adjustment at the highest treble plate bo=
lt
location also has limitations in <STRONG>any</STRONG> system, as I see
it , the stiffness of the plate flange bolted to the block &=
amp;
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. B=
ut
hey small amounts are often all that's needed.</FONT></DIV>
<DIV><FONT size=3> In my first encounter with using an
adjustable Coleman plate suspension system allowed me to apply much nee=
ded
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......</FONT></DIV>
