[pianotech] agraffe prep redux

[David Love]

A little off the original subject.  These are half agraffes I'm talking
about for which a q-tip is relatively useless because they're open on one
side and you won't be able to give a "gentle shove" and have them stay in
contact with the string bearing surface.  The recommendation I got from Del
was to us a small, fine rat tail file and bevel them carefully at a 45
degree angle on the speaking side.  Clean them up with a brass brush and
don't worry too much about the non speaking side, FWIW.

Jude,

Like Paul, I find the Q-tip (when given a gentle shove) does well to take
the necessary shape when polishing.  I think the photos give a pretty good
example.

I like the idea of polishing the agraffe holes with Q-tips (and Paul's
photos microscopic images certainly made a nice demonstration), but I have
not been able to find any Q-tips where the diameter of the shank allowed me
to get in deep enough. As a result I still continue to floss with a very
high grit abrasive cord. Q-tip suggestions?
