Hello Ron N.! A remark about your Steinway B rim: > Even with that "iron fortress" rock maple rim, it was > absorbing more soundboard energy because I had removed the > MASS of the clamps from the rim. When I got the plate bolts Don't the B's have only a few longitudinal beams connecting the stretcher to the tail and perhaps the curved part of the rim? If so, then it is a reason for the vibration of the rim, because it's not stiff enough transversally (I mean from spine to curved side). I think in such a case, adding 1-2 transversal braces would make the whole rim much stiffer, thus providing a more rigid support for the soundboard and somewhat improving sustain. What do you think?
