But if the idea = is to add tension to the board and the board is already under downward = pressure from the strings, isn't pushing up from the bottom taking = pressure off the board by neutralizing the downward force applied by the = strings? =20 At any rate, it seems that whatever the system it should be = adjustable, something you could ratchet up or down. To precalculate the = actual amount of additional pressure needed would be difficult, so a = system which allowed you to increase or decrease pressure and listen to = the results would make the most sense to me. David Love Conceivably a spring could be positioned either above or below the = soundboard panel. Since most of the discussion to date has involved = pianos with collapsed--or collapsing--soundboards, not much thought has = been given to helping them along with this process. The string load = seems to take care of the downforce requirements all by itself. The idea = of the springs has been to either slow down or, perhaps, even reverse = the collapsing process. Consequently most, if not all, of the work done = in this area has involved placing the spring(s) below (or behind) the = panel. Again, much has been written on the subject. Check it out.
