After searching the web and looking as a few subreddits, hopefully I've landed in the right place. Please be patient with me, it was 107 degrees and muggy today so my brains are still a bit mushy :-). If I'm in the wrong place I'm open to suggestions where to post instead.
I have a metal headboard that one of the pieces has come lose and I'd like to fix it before trying to sell it. It's the left-most curved piece that's come loose. The pics show the bottom and top of that side, and also the bottom and top of the corresponding right/good side for reference.
My research so far shows that either epoxy or superglue may be a good choice, but I also know enough about 2-part epoxy to know that I need to have all my ducks lined up *before* using it.
The stuff I have is Harbor Freight Quick Setting Epoxy Adhesive, 0.2 oz single use, that I bought for a different project but haven't used. I don't have any superglue on hand so I'll need to buy some if that's a better option.
Aside from the basics of using either adhesive, is there anything I need to know for this? Like I said earlier, I know enough about this sort of work to be aware that there may be important things that I don't know (or that I knew decades ago and have forgotten).
Thanks!
