Rim splitting

[John W. McKone]

Hi All!

I just got back from looking at a Yamah CFIII that I will be rebuilding
soon, and found one heck of a rim split.  This is not your typical
lamination separation that any of us who rebuild see fairly often, but a
horizontal split completely through the rim, from inside to outside.  The
split is about a foot long and is located about one inch above the
soundboard.  It begins on the bass side of the piano, just where the rim
begins to curve around the back.

Has anyone had any experience repairing something like this?  I'm trying to
decide what glue and/or filler to use to get the best combination of
stability and structural integrity.  It seems to me that fiberglass might
be the best bet for gap filling, but may not hold the split as well as
something like resorcinal.

Ideas? Comments?
