Best Epoxy/Glue to Reattach Sheared Off Horizontal
 
Hi guys,
Seeing as literally everyone here has more experience with fixing things than I do, I thought I'd ask this question and see if I can learn a thing or two...
So, what is the best epoxy/glue/other adhesive for reattaching sheared/broken off horizontal stabilizers to a diecast aircraft? I know super glue is bad, as the fumes are very likely to damage the paint, so can anyone recommend a different adhesive?
In a different thread someone talked about using two-part JB weld to reattach some pieces, which I'm definately considering getting, but I'm sure there's more. Last time I tried to cheap out and just use white glue, which held for awhile, but I'm on the hunt for a permanent fix, if possible.
Thank you in advance!
-Phillip

It depends on how it is broken and the size (thickness) of the stabilizer.

JB Weld epoxy should do it. Just wipe off any excess that may creep out from the crack.

If it's a tight fit you can use white glue.

Ah yes, I was at work when I posted the question, so I wasn't able to get pictures at that time. But since I'm home now, here are a couple.
Unfortunately they were both sheared completely off. There's some Elmer's glue left from the temporary fix, but that shouldn't be hard to get off.

What is 'white glue'

snowghost 09-07-2019 08:52 PM

Elmer’s Glue-All

Some time ago I did something that I thought impossible.

The two vertical fins of my Bréguet Deux Ponts separated from the horizontal surfaces (it was before painting).
The model is white metal.

I made good use of "synthetic metal" that is used for auto body repair, two components : resin and metal powder.
First remove the adhesive residue on your model.
You mix the resin and the metal powder, be careful, it is toxic and you apply with a fine brush.

In your case, the stabilizers have to be secured in the appropriate position.
You need to make an assembly jig, that's what I did for my Bréguet.
The mixture will be applied on the metal, cover carefully the painted parts with masking tape, the excess can be removed with alcohol.

I attach three pictures showing how thin the fins of the Bréguet are, the synthetic metal I used and a jig I recently made to restore a model with its vertical fin badly broken.
The fin was secured as shown, fuselage and wings taken prisoner in the jig.

Restoring your model will take time, think twice, choose the best solution to make your jig.
Sometimes, what looks impossible is possible, simply, it takes time ...

Good luck.

Jean Pierre.

It's tough to repair when it is sheered-off like that. All you can do is use an epoxy (very messy) or super glue to 'fix' it in-place but I'm afraid any slight stress will just break it off again. Plus it's next to impossible to do it without having a lot of excess glue being visible or messing the fuselage up with the glue.

I've never tried it but you might be able to use a very thin gauge Dremel drill bit (not sure if such a bit exists that is that small) to make two corresponding holes in the slot and the stab - using a thin wire or pin inserted in to both holes - then stabilize it with a little super glue or epoxy.

When you glue it, tape everything but the splice. That needs accurate preparation, but the result is worth it. Be sure to peel of the tape before the glue is totally hardened. That should prevent the fuselage from most mess.

Good call on that one.

Much appreciated everyone! I'll be sure to tape everything else off to limit the mess on the rest of the body. The suggestion for building a proper jig to hold everything in place while the glue sets is also a great idea. I wish I could make one to the same degree as Air France did, as it looks like one heck of a solid jig!
I was thinking of trying to do it the cheaper way, by putting the model back into the bottom plastic packaging tray with some epoxy on the sides and finally pressing the stabilizers onto the sides. Which hopefully will hopefully hold everything in place, and at the proper angle, which is what got my last time I tried this.
I also found this epoxy at my local Home Depot, it's called JB Weld "ClearWeld", which apparently dries mostly clear, which will help once I inevitably get it all over the rest of the model...
I'll try and get it done tomorrow, and then post pictures of the results.

Alright, for all who may be interested, the aircraft reconstructive surgery has finally taken place! I didn't start with many tools (from left to right) just the epoxy packaging which doubles as a mixing tray, a microbrush, a little pointy stick for quickly and precisely moving any epoxy away from an area it wasn't supposed to be on, a wooden mixing stick which came in the package, the JB ClearWeld epoxy, and a pair of disposable gloves, since this stuff apparently causes skin and eye burns. Though if I hadn't found the gloves in one of my drawers then I would have probably taken a chance and forged on without them.
The process was fairly simple, I squeezed both parts of the epoxy out into the package mixing tray, which I thought I couldn't mess up, which was wrong. Even though the plungers are linked, meaning both go up and down at the same time, one of the chambers had a decent amount of airspace in it before the goo came out, so I got a bit more of one side than the other.
Now, any good model maker would have probably thrown out the batch and squeezed a new amount out, but I didn't think about that and once again forged ahead.
Mixing was straightforward, it took about 30ish seconds for the goo to combine, though there apparently isn't any specific length of mixing time listed on the package.
After that I used the microbrush to apply the epoxy onto both the aircraft body and the stabilizers. From what I saw there really wasn't any seepage away from the surgical site, so I then put the aircraft into the bottom half of the plastic packaging, making sure it wasn't touching the sides, then I carefully pressed the stabilizers into their appropriate place.
Next I let the epoxy dry for about five hours, then took the aircraft out for pictures, and to make sure it wasn't stuck to the package. After three or so hours of being out I noticed the stabilizers were starting to droop, so I put the model back into its packaging to (hopefully) cure for another four or five days.
And there, friends, is my adventure into trying to repair sheard-off parts of a diecast aircraft.
I'll post more pictures and info once I take the model out again.

Awesome. Looks mint. It should actually be stronger now than from the factory.
I really like the idea of using the plastic packaging as a makeshift jig. Brilliant.

Hey well done fixing this ANA B777-381ER :cool:
Looks like it all packed out very well :)

Great job.

When facing this kind of problem, you have to be creative and find the best solution.

Thank you Phillip for sharing these pictures.

Looks awesome! I could never do such a clean job.

It looks good! JB Weld it is. Thanks for the presentation. If the horizontal stabs should break off again, Widebody's suggestion on post #10 was the same idea i was thinking would definitely secure them.

You know, I was definately considering that, too. I loved the idea of drilling a couple holes and sticking something like a brass rod in between to really secure the parts! The only reason I didn't try it this time is I don't feel like I have the skills for that, and I'm especially lacking the powered tools needed for that kind of job.
Coming from the world of HO and N scale model trains, small parts and wires don't really scare me. That's mostly because I haven't really worked with drilling into metal at all, since all the train bodies are basically plastic, I've never had the chance.
Even depending on the type of plastic it can be hell to drill through, so I can only imagine how hard it would be to drill into a solid metal aircraft body...
Nevertheless I'll definately keep that idea under consideration, as it sounds like a great experiment for the next time I knock off stabilizers...
(Yes, we all know this will happen again)
