For a quick fix @name_of_user, I think it turned out good for using CA glue.
Like what @MJ1 said, epoxy would be the better long term fix. If the CA cracks, it will be fairly easy to pick the rest of it away thanks to its brittle nature. If you are worried about the brass insert getting adhesive in it:
Take a screw that fits those threads and put vaseline (petroleum jelly) on the screw and the threads, then screw it in a little ways into the insert. You can then apply epoxy liberally without fear of it getting into the hole.
If you got a little too much on top of the insert you can just sand the excess down flush. My old Model Plane mentor showed me this when we would nearly flush mount hinges to control surfaces on wings and tail. The epoxy would bond everywhere but the movable part of the hinge we put petroleum jelly.
Great job on the fix and the detailed pictures.
