Best Answer - Chosen by Asker:
Action height is very dependent on the string height off the first fret!. This is adjusted by cutting the slots to the correct depth on the nut!. It should be done by a professional luthier!.
Do not use epoxy!. It is common to have to replace/adjust the nut!. If you epoxy it there may be damage to neck/fingerboard getting it back out!. Use Elmer's Titebond or a similar glue!. Do not use much!.
At a guess, I would say the nut is probably cut correctly now!. To check it!. String the guitar (putting the nut in but not gluing it yet), tune it up, and try it!. If you don't get fret buzz and it's not too difficult pushing the strings down to the first fret, you should be OK!. Loosen the strings up (a lot - this might get a little messy) slide the nut out, coat the inside of the nut slot with Titebond, and put the nut back!. Try not to slide it back in, if you can so as not to push the glue out!. You might try it first dry to see if you can do it (see if the strings are loose enough)!.
Hint: I always down tune my twelve string acoustics one note (D instead of E) to make them easier to play and relieve a bit of that pressure on the neck!. It is very common for twelve string necks to warp!.Www@QuestionHome@Com

I have to wonder why you need to glue the nut back on!. If the previous owner managed to get that thing out!.!.!. it's usually so solid you have to chisel it out!.!.!. then I have to wonder what ELSE that idiot did to the guitar!.

If you have the nut then you can use any epoxy to glue it in place!.!.!. just so it's solid!.Www@QuestionHome@Com

Regular plastic cement should hold sufficiently!. You don't want to glue the thing in too solidly because the nut is made to be replaced!. They wear with the strings being tightened and loosened, and sometimes they are deliberately shaved down by owners to get the strings closer to the fingerboard!. Over time, one or more of the grooves may wear too much and then all you should have to do is pop the neck nut off and glue in a new one!. If your action is critical to you, it would be best to have this done by a Luthier!. They have the proper tools to adjust each groove with precision!. If string height is not as much of an issue, then a little sanding at the bottom and a little glue plus a little pressure (make sure that you put a piece of wood between the clamp and the bottom of the neck so there is no scarring) and a few hours of waiting are all that are required for this simple repair!. If you are merely replacing a neck nut that has come loose, make sure you clean both the nut and the surface you are sticking it to!. I have even used Elmer's construction Glue, but it takes longer to set up!. I am secure in the fact that it will be quite easy to remove when needed however (water soluble) and it is relatively easy to clean up!.Www@QuestionHome@Com
