I will most probably float the soundboard in the deep base. I won't need to glue new ribs and there are none in the far corner that would interfere. I will probably also replace the board (and ribs) as it has collapsed and I am wondering just how long should this float (cut/rip) should be. What are the criteria involved in deciding on the length of the cut? How do factors such as thickness of the board, distance of bass bridge to rim come into play here? Another question I have been wondering about is whether anyone has ever floated the soundboard at the high treble end, along the short side, perpendicularly to the end of the bridge. What are the likely results of such an experiment. Btw the treble end float idea is just theoretical curiosity. Can someone with experience in this matter share a few thoughts ? Thanks, Peace, Jean-Jacques Granas Warsaw, Poland ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
