John, While we're trying to protect our ears, we need to also protect the piano. Has anyone talked about the need to be careful with the agraffe bearing surfaces? If we press too hard on the string in the direction that would cause it to cut into the agraffe bearing surface, it seems like that would potentially damage the surface and set up a poor termination. I'm thinking that if you push sideways or down and to the side as you described- that should be safe. The termination point of the string is in the top of the agraffe hole and hopefully?? not in the "line of fire" for this procedure. Also, there maybe similar danger in over-agressive use of the string hook. I would like to hear what Paul Revenko-Jones or anyone else that has done some up- close photography on agraffes, thinks about this string setting procedure. I'm not sure how much pressure it takes to cause the string to deform the brass.
