    I managed to break the top of my u-kala, it has a big crack/opening on one side and a smaller on the other. A local luthier said it'd be 300$+ to fix it and its only around 350 new so its not worth it. I'm looking to fix it myself the best I can. I'm just looking for ideas, whether putting a slim piece of wood under and screwing it on to mend the cracks or whatever just so long as I can still play it without it damaging more. Surprisingly it still sounds pretty good I just feel the tension from the strings will soon do more damage. Open to all suggestions! I dont expect it to look/play perfect, just something to still mess around on.

    The technical term for that instrument is "completely F'd".

    Agreed, but I dont just want to trash it, It still plays decent and will still be fun to mess around on and take in the car ect.. should I just leave it how it is?

    It's repairable, but not an easy DIY job. I would start by making a caul from half-inch ply or MDF and another from Plexiglas, about 2 inches wide. You want to use plexiglass so you can see the results of the clamping. The length will be limited by what you can feed through the sound hole.

    The wood caul goes inside and the plastic on the top. Clamp the two together with C-clamps through the sound hole, and see if you can flatten the splits. If there are no significant gaps, then cut a thin bit of spruce that runs the length of the crack, about 3/4 inch wide and glue it on the underside of the top bridging the split, using the cauls and clamps. After it dries you may want to deal with any cosmetic issues - or not.

    What is the condition of the top bracing?
