Mike: I had to replace an agraffe on a Steinway in our practice rooms. It is the second one I've replaced on that piano. It and 10 others that we have were all made in 1983. The 11 that we have are all within 399 serial numbers so they came out very close to each other. I'd think that if it were a bad batch of agraffes that we'd have problems on some of the others. I think now that it is probably a guy on the line who just turned them down too hard and left too much internal stress in the agraffe. dp David M.

The other day I saw a 90 degree angle drill adapter with a small chuck that connects to your drill that might work. You might also consider going up from the bottom of the pinblock with a R.H. close coupled or right angle drill which will spin the agraffe out through the top. It will have the same effect as a L.H. drill bit coming down from the top. Why do some have this affinity for broken agraffes? Just lucky I guess.....
