Do you mean to insert the eye bolt HORIZONTALLY into the rib, then, and align the hole so that the screw then is inserted through it and is screwed upward into the sound board from the bottom? Doesn't this assume a lot of drawing power of a small wood screw into a thin piece of spruce? Does this leave a screw tip showing through the soundboard from above? Or would you use a machine screw and washers/nuts to spread the load?? ? Geoff,? ? You've got the right idea. Yes, there is a possibility that the tip of the screw would show up through the top of the soundboard. But at this point,?what's more important,?the physical appearance of the soundboard?or the vibrations of the soundboard?? As I said,?it's not a perfect repair, but maybe better than nothing. ?
