	I've met with several Steinways from, I think, the 1970s, which
had agraffes with insufficient counterbore. The hole in the agraffe was
pretty much just a straight cylindrical hole. I found that leveling
strings on these pianos would often result in more problems than just
leaving the strings where they were. In many cases, pulling a string up
would cause a buzz--either immediately or down the road a bit.
