[pianotech] agraffe prep redux

[PAULREVENKOJONES at aol.com]

If you can keep a consistent angle of pull with abrasive cord, and rotate  
it so that you create and follow the radius you are trying to create, then 
more  power to you. Simpler by far is using the Foredom/Q-tip, and less 
invasive and  uncontrolled.

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).
