Repair Tips on fixing broken wing?

I'd guess anything you do will leave a visible seam that you'll have to conceal, whether by filler and sanding or possibly just by painting the wings. I'm hoping others have more advice in that regard as I don't have much.

Super glue will work, but for a piece that big and heavy will probably only provide a rather weak repair prone to breaking again the in the future. Do you move this doll or leave it as a static display? Super glue may hold well enough for a static display. If you do move it (or honestly just in general) I'd lean more towards two part epoxies as they are much stronger.

If you try super glue or epoxy and find the repair just won't hold and it keeps breaking as you move the wings or doll I'd suggest pins. By pins I mean very carefully drill a few aligned holes into each side of the split, maybe ~1/2 inch (~1cm) deep on each side. Then insert small metal pins or rods into the holes. You can make the holes a tiny bit bigger than the diameter of the pins to make alignment easier since they'll be hand drilled. Then when you glue/epoxy the pieces together also put some into the holes before you insert the pins so that the pins get sealed in place as well as the broken edge getting joined. I've done this on several things that just wouldn't stay "fixed" and it's made a huge difference.

Of course drilling pin holes carries some risk. If you're not careful you could cause a chip or if you get the angle wrong drill out of the side of the wing creating a visible hole in the good part. Also multiple pins are much harder than a single pin (such as on a small repair) as they all have to line up such that you can slide the two parts together with all pins inserted. So if you've never done it before I'd certainly suggest at least searching for some videos or other tutorials before you try it.

But I think I'd try it without pins first. Yes if it breaks again you'll have to clean off some old adhesive and end up with a slightly more noticeable seam, but it's just so much easier.

 

I second what scripple said about super glue and/or the use of pins with it. I would like to add if you do use pins remember to use a mask rated to filter particles as resin dust is toxic.

I've worked with superglue and toys a bit over the years, and it might hold fine without needing to be pinned if you are very gentle with the wings. I have not used epoxy much but a two part epoxy might have a slightly stronger hold.

 

I agree with what others were saying. In order to conjoin the pieces, superglue or epoxy resin might work. For the seams, perhaps apoxie clay could help cover it up if you smooth it out well enough, or sculpt some details? It might also help add more strength to the wing overall. I don't know much in this area, but I've seen people mod parts and so apoxie clay comes to mind for fixing aesthetics. For the epoxy resin adhesives, I know there are industrial strength types but I don't know how specifc resins will react with it, but it might give a bit more strength than regularly used epoxy resins. I wish you luck in this endeavor!
