>>Does anyone have agraffe to strike dimensions for note #1 on a >>Steinway C and an 85 note A (both around 1890)? > > >The A should be close to 152 mm. But these things vary on handbuilt pianos. JD asks: >>How do you arrive at that figure, Ed? The speaking length of A-1 on the model C is roughly 1624 mm. 1/8 of that is 203 mm; 1/9 is 180 mm. Not having a C to hand, I have no way of giving an authoritative answer to the question but 152 mm seems unlikely. If you measure from the front of the front rail to a point 3.5 mm into the speaking length of note A-85 and then measure that distance at a right angle from the rail to a point on string A-1, that should touch the strike line, I think. << I arrived at the figure from measuring from the inside face of the agraffe to the strike point on the string that the hammer contacted. On note # 1 of an 1892 model A. Others? Ed Foote RPT -------------- next part -------------- An HTML attachment was scrubbed...
