Hello Phil, Providing the hammer molding is perpendicular to the string plane, the force on the string is F*cos(A). "F" is the force which is theoretically available if the hammer molding and the shank are perpendicular, and "A" is the angle between the shank and the string plane. The formula says that the force is maximized when the shank is parallel to the string plane. In addition, if the shank and hammer, and the hammer and string plane are not perpendicular, there is actually a wiping motion between the hammer and the string. This motion is always there when the string deflects, but it is minimized with the 90 degree angles. Vladan I would like to revisit the idea that shanks should be parallel to strings at hammer contact. ... Any thoughts? Phil __________________________________ Do you Yahoo!? Yahoo!
