Hi JD. Have not read Junghans book no. But I have noticed that getting the same amount of downbearing force on a long string vs a short string requires quite a bit more string deflection and hence deflection angles. Most of what I read here is that usual practice is to have very little downbearing angles in the lower areas of the scale, and more in the treble. Which goes in the opposite direction of evening out downbearing force. I have designed no scales as of yet... well one sort of... and am admitedly new to the whole field of scale design and am of course as a result very unsure of design principles.

Have you not read Junghans in 'Der Piano- und FlŸgelbau' either, which details a scale on very similar principles to Wolfenden's; not that several makers were not already following these principles -- there was nothing new about it in 1916 -- and most still do. In fact an 1865 Kirkman I am currently working on might almost have been the model for such a scale. What scales have you designed and what principles did you follow? JD
