[pianotech] agraffe prep redux

[Jude Reveley (Absolute Piano)]

Hi David,

Sorry I couldn't resist the digression since I've been meaning to ask for 
awhile now, but to your point...I would pull the semi-agraffes out, 
sandblast the dirt and finish off, toss them in a vibratory tumbler, 
reinstall them, shoe shine them with abrasive cord followed by some Flitz 
buffed with a dremel polisher or Foredom and Qtip. I think the abrasive cord 
might be easier to work consistently than the file (unless you feel you need 
to aggresively remove some material).
