A short beam from the belly rail to the case in the same area would allow for another nose bolt that could take the place of the bell. I cant say the bell has any effect in and of itself to influence tone but does stiffen the plate web where it attaches thereby influencing tone. There must be a modest down force of the bell bolt to do so which by the way will increase the downbearing a small amount (tone effect) These bolts also seem to come loose from time to time and cause a weird rattle. Take the coupling bolt out of a D sometime and listen to what happens to sustain through that area. Del Del I took your suggestion out of curiosity today. I have an almost completed D in the shop which by now I know intimately in the tonal sense. I listened carefully to octave 6 & then disconnected the bell bolt. Honestly it was difficult to say there was any desernable change. However when I put it back in I decided to tighten it a bit more & the sustain though slight increased on a few notes primarily C-6 ,thru D sharp 6. It was so slight that I cant imagine a beam and nosebolt wouldn't have the same effect. For all its touted features I'm questioning its benefits not to mention the torque it puts on the rim where some separation is often seen. Know what I mean?
