List, I am installing new butts, shanks, and hammers into an old Knabe upright. The replacement butts I bought are Tokiwa. I didn't think much about the fact that these butts are made in Japan, and Knabe is an American upright. The "actual size" photo of this particular Tokiwa butt in the catalog matched best with the old Knabe butts that I am replacing. However, the one dimension you cannot see in the photos of the catalogs is the exact location that the shank hole is bored into the butts- they only show a profile. Herein lies the nature of my question: I lined a new Tokiwa butt and shank up in the action, side by side, next to the old butt/shank/hammer. It turns out that the placement of the shank-hole in the new Tokiwa butt is a little over 1/16th of an inch closer to the strings than the old butt. This puts the hammer and shank at a different pitch resting on the hammer rail, and more importantly at impact with the strings. With these new butts, the hammer will make impact with the strings just BEFORE is reaches a 90 degree angle (assuming the original geometry of the butt/shank/hammer to string dimensions did so). Will this be a problem????? Your input is greatly appreciated.
