<DIV><FONT size=3> My guess is Mr </FONT><FONT
size=3>Bluethner didn't pay that much precise attention to the amount=
of
crown especially if he was compression crowning ,which he
was. Judging by the one & only one I've rebellied he didn't g=
et
much crown for long as his ribs were to flat & not tall. Panel was=
falling apart.</FONT></DIV>
<DIV><FONT size=3> If he had a 60 ft radious thru out I'd be
surprised. And historically ribs that short meaning not tall ,as we've=
discussed much, won't hold a compression crown many years. </FONT></DIV>
<DIV><FONT size=3> I think they just knew
compression was apart of the accepted recipe of the day & this is =
how
it was done.</FONT></DIV>
<DIV><FONT size=3> He did have a beautiful sweeping cutoff bar thoug=
h and
his ribs did some fanning as I recall.</FONT></DIV>
<DIV><FONT size=3> Crown the ribs to something tolerable &=
the
piano will be fine. His scales were also horrible & whacky & all ove=
r
the map. a new bridge is what the one I did needed. Didint' get it thou=

<DIV><FONT size=3> Hey it is what it is as my wife says.</FONT></DIV=

<DIV><FONT size=3> Rumor has it that his glue maker was t=
he
worst and so getting a Bluethner apart is a cake walk. That's wh=
y he
used all those screws in the face of the board. It'll be interesting to hear=
the
progress on yours. If you need advice........</FONT></DIV>
