More Agraffee

[PianoGuru@aol.com]

Hi Michael

Baldwin has a technical bulletin describing such a repair.  There are over
sized agraffes which would allow you to tap the hole to a larger size and
install the oversized agraffe.  Only the threaded portion is oversized.
 Another option is to drill and tap the hole from the bottom, but not all the
way through.  Then install a special bolt with a hole drilled through its
length.  When the bolt bottoms out in the hole it is broken off flush.  The
threads for the original agraffe are then tapped in the pre-drilled hole in
the bolt.  This repair is used by Baldwin and O. S. Kelly, and is described
in more detail in the technical bulletin available from Baldwin Technical
Support at 501-483-6116.

Good Luck,
