information from the article is the use of a counterbore to set the
position correctly. It really helps in cutting down the use of the washers
and the over tightening problem...>>

These are probably not the particular articles to which you referred, but
will adequately do until someone comes forth with the information.

1) August 1983 Piano Technicians Journal, pages 22-23, The Eclectic's
Notebook, by Christopher S. Robinson, Connecticut Chapter introduces the use
of a HOLLOW MILL for this purpose.

2) May 1984 Piano Technicians Journal, pages 27-29, Shop Talk, Agraffes, by
Susan Graham, RPT, San Francisco Chapter explains that "...a hollow mill does
not come with a stem...", whereas the counterbore does.  "...It has the same
center hole and protruding blades arrangement..."  The article goes into
detail on replacing a set of agraffes from one of the best technicians
around.
