Esteemed Colleagues,
    Happy New Year to one and all!  And thanks to everyone who is so =
willing to share in their knowledge and experience.  I, and many others =
who don't post that often, surely appreciate the knowledge posted to =
this list.
    We have a Baldwin upright here that has ribs separated from the =
board, along a specific line, just south of the bridge.  It is so close =
to the bridge edge, that I suspect that there has been some bridge =
twisting, or roll, that just pulled the board away from the ribs at =
those spots.  If you run your fingers next to the ribs, you can feel the =
valley created in the board.  Is there a way to clamp and glue WITHOUT =
pulling the plate, as this piano is not worth doing that much. =20
    I have been thinking about this, and am looking for a suggestion, =
articles of reference, whatever you can share!
Thanks in advance!
Clark Sprague, RPT
