<DIV><BR>My concern would be over the integrity of the plate in the HP =
area.
Del pointed out some time ago that this area<BR>is not thick enough to =
support
vertical HP's reliably, the bass is but not the treble. Is there room =
under
the plate<BR>to install a thickness of metal to brace the area or =
would that
be warranted?</DIV></BLOCKQUOTE>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080>Actually, it is but one must use at least a =
moderate
amount of common sense. The Baldwin plate was thickened to prevent =
breakage if
the strings were placed quite high on the pin. I've seen some of them 12 =
to 15
mm up on the pin. That placement puts quite a stress on the plate. The =
S&S
plate is thick enough to accomodate a string placement approximately as =
high as
it would be if it passed over the original back bearing bar -- usually 3 =
to 5 mm
above the plate surface through the tenor/treble. They can ride as much =
as 5 to
7 mm off the plate surface in the bass -- where the vertical hitchpin is =
most
benificial anyway -- without problems. </FONT></DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080>The problem comes in when the technician uses =
the
vertical hitch to accomodate poor placement of the plate or poor control =
over
the bridge height. </FONT></DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080>One reason -- perhaps the major reason -- why =
Baldwin
introduced the vertical hitch was to facilitate manufacturing. In my own =
work,
however, I've come to realize it actually provides a superior string =
termination
and we use them quite a lot. I don't know if Mr Conklin understood all =
of its
acoustical advantages or not -- I don't recall reading anything he may =
have
written about them -- but I expect he did. He is a pretty smart and =
thoughtful
man.</FONT></DIV>

<DIV><FONT color=#000080>This is not so easily done. The fit on most =

plates is rather poorly done and seemed to require a lot of hogging away =
