Back separation

[Jeff Stickney]

     Back separation - the piano's, not mine.  Can anyone supply me with
or direct me to a Journal article on the procedure for repairing a
separating back on a vertical piano?  Should the tension be lowered? (I'm
assuming yes.)  Would you use wood glue or epoxy in addiation to
installing bolts front to back?  Should you draw the separation together
using clamps and install the bolts, or can the bolts be used to draw it
together?  Thanks for any info.
