On the 1960s Hamburg Steinways I've come across you'd probably need 
to counterbore right through the iron plate to get the agraffe to 
hold the string at the proper strike height at least in the middle of 
the scale.  Let's say this is a nice theory to be immediately 
consigned to oblivion, since it could never be put into practice -- 
that's supposing you mean a straight straight-edge.
