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 ?
