Mat Roop Posted June 3, 2022 Report Share Posted June 3, 2022 I am not a maker, so maybe this makes no sense but... I'll ask anyway... While recently repairing a back plate sound post crack made me wonder what would happen if the back plate were to be installed in reverse with the arching concavity outward. that should make for several advantages ( I think) 1- with changes in humidity, the post fit should not change as both plates would expand & contract, not exactly but similarly, keeping the spacing between top & back the same... more significant for the cello or bass 2-pressure on the back plate from the post should be less likely to create a crack 3-sound radiation from the back plate would be to the outside instead of being trapped inside and interfering with the vibrations of the top plate. A speaker cone always projects from the concave side... so why not the back plate?? or for that matter why not both plates with the concavity to the outside? I've been thinking of taking a less valuable violin and making new taller ribs and fitting the back plate in reverse. Of course I'd have to do some calculation to try to keep the internal volume the same as original... if that matters. Anybody thought of this before??? Thoughts on what the results might be?
