[pianotech] Agraffe for Chinese piano

[Isaac Sadigursky]

Hi,Mark !
Sorry if I made myself not clear:  I meant Re-tapping tha agraffe  
HOLE,not the agraffe,and only if nessesary,as a last resort....BTW,I  
do have 1/2" plugs ready  made for 7/32" and 1/4" inner holes,because  
I had to deal with badly damaged holes.
I even don't have dies to re-thread agraffes,but do on a few occasions  
had to re-tap the holes...Thank you.... Nice weekend to everyone...  
isaac.
