I wanted to let you know and also, David and Ed, what I observed today when I was back at this piano.
<P>These strings do rise toward the bridge. Maybe about 3 degrees of rise - but I'm not sure if I measured that accurately. However, I know that the hammer shank should match that amount of rise upon contact with the string so I put a little line level on the shank.</P>
<P>On some of the old hammers the wear is significant so I had to guess about how much more hammer there would have been when it was new. The holes I have already bored, unfortunately, are probably making the hammer "too long" and undercentering. The bore distance I used was the result of doing the simple math: subtracting the heighth of the hammer flange center pin from the string height ( and not accounting for a rising string). </P>
<P>I don't think that there is enough said about that kind of potential error. </P>
<P>Tomorrow, I want to plug a couple of these long bored hammers and rebore them at the distance of 48 mm like the old ones.(Instead of the 2 inch bore) Then, I will try those on the piano before I do the rest. Is this a smart approach? I tried regulating (aftertouch priority method) the long bored hammers and their new shanks but to get a note to play really well, a real short blow was required, like 41 mm.</P>
<P>The plugs will need to be end grain on the side, true? What is the best way to make those? A hardwood dowel would have incorrect grain orientation I think. </P>
<P>Can you visually detect rotation in a wippen rail? <BR></P>
<P>Gratefully,</P>
