Split treble bridge

[Frederick G Scoles]

This is my first post to the group.  I've been a guild member for seven
years and just recently completed the tests to upgrade from Associate to
Registered Technician. (Whew!).  Have been in the Chem. Dept. (SUNY
Oswego) for 13 yrs. as the Instrument Specialist (Electronics, test
equipment, etc.).  With pianos, I rebuild about 2 players/reproducers per
yr. and about 25 hrs. per wk. tunings, reconditioning, regulations, etc.
Last month I was pitch raising a 4 yr. old (relatively new) vertical
piano and found the top 4 treble notes would not tune.  Then I noticed a
bridge split about 3 inches long which runs along the top (speaking
length) bridge pins and extends virtually to the bottom of the bridge.
About 8 of the pins also fell out.  The factory and dealer both want me
to repair it (versus replacement).  Any journal articles I've seen on
this usually mention that such a repair may not be permanent.  The
factory prefers a good epoxy and the dealer suggested a good CA glue, so
I assume I must use the epoxy (long cure-time West or Duro?).  The bridge
is solid (not capped).  The part which split appears to have also warped
since the split is at least 3/16" wide on the treble end; and the break
was not "clean", as it has many splinters.  My concern also is how long
such a repair might last.  Thanks for any advice or article references.
