There are no loose braces. If you align a crack like that (where the plates exaggerated look like: / \ ) in the lower bout and insert glue in it, isnīt there a risk to put tensions in the top, that will make it less vibrant in the most important area?

If the bracing does indeed look like that and none of them are loose then you have a crack that crosses the bracing which makes it more difficult to repair. If it closes up nice and tight though just by aligning it then you can glue it back together. If not then it will need to be splinted.

If anything, the top is not vibrating properly now since you essentially have two large sections of the top that are separated and acting on their own. Once you put them back together then, in theory anyway, you should have a better top and one that produces a stronger monopole 'loud speaker' mode.

But that's just working it out on paper too. You may very well notice no difference at all but imho it should be fixed.

2/3 of the crack in top glued. First runs approx. 1 cm from fretboard. Is there a big pressure on that part of the top?
(I,e, would it need an extra supporting layer of veneer, or just cleating each 5 cm? Or, maybe even, just let it be?)

Then the big matter the crack below the sound hole. To mate the surfaces better they could either be pressed down with at clamp or some strong rubber band (to press the edges down with a stick in between). I canīt choose either idea. Or, do you have any suggestions, please?
Regards
