If you are putting on new hammers, which I presume that you are, why not bore your hammers (or have your hammer supplier bore them) to the diameter of the shanks that you will be using? What make of piano is this and what kind of shanks do you have on them. What is the diameter of the original shanks and the upright shanks? Are the knuckles on the old shanks round like most shanks, or another shape. You will be much more likely to receive good answers if you are specific about makes and models, and offer as full a description of the part in question. There is no such thing as generic piano parts, there is too much variety.

Poulson Sent: Thursday, May 31, 2012 5:21 PM To: pianotech at ptg.org Subject: [pianotech] Square Grand Hammer Shanks It turns out that the hammer shanks on the grand I am working on are undersized, about the diameter of spinet shanks but longer than the spinet version. I am thinking about reducing the ends of standard upright shanks after cutting them to size. However my standard hammer shank reducer can't take off that much (.04 inch). Is there such a thing as a tool that will reduce the shanks to the right diameter available? Thanks Patrick C. Poulson Registered Piano Technician 530-265-1983
