I’ve searched this site and others, and while this has been addressed many times (with many differing opinions), I couldn’t find a situation quite like mine.

I’m installing brass hidden barrel hinges on a small walnut box. The hinge barrel is 8mm, so it doesn’t fit in an 8mm hole. I used a smaller bit with sand paper taped to it to widen it a bit. I also found aligning the holes perfectly in all directions was exceptionally tricky. The result is when the hinge is in the hole there’s a fair amount of play. I need to glue the hinges in the holes and they can’t move once there.

I initially thought of silicone but it would be too flexible. I don’t think wood glue (Titebond) would hold it, so I am now thinking JB Weld 2 part epoxy. I have some on hand but never used on wood to brass connection. My concerns are (1) will it bond to the wood and metal, (2) will it hold, given it’s a hinge with movement, and (3) will wood expansion be a problem with the hard epoxy?

Edit to add – I found a helpful site, something like This to That where you can put in the two materials you are gluing and it will give you the glue to use, but doesn’t address the concerns I mentioned.

Any epoxy should work fine, but you get a permanent connection

If the outside of the hinge barrels are shiny, you might want to give them a light sanding with 100-grit so the epoxy has something to grip. Wipe them down with denatured alcohol, too, to get oils and crud off.

I haven’t used them, but I understand that some brands have a set screw that expands the barrel in the hole to hold them in place. Use this type and you should have no problems and (I think) they will be removable. Otherwise, most any epoxy should work. Of course, don’t get any into the mechanism. Wood expansion/contraction should not be an issue.

Along with the set screw,
There are 1/2 countersunk holes on the sides which I believe you can screw the barrels down.

Bilyo and the red arrow rules! ...I am yet to see a hinge that you glue in …but always keen to learn!!

Some do have a groove and countersink where you use a screw to hold it down and some have a built in set screw that acts to like a wedge to expand the barrel at the bottom to lock it in place. Check out about 2:00 minutes into this video. The one shown in the video has both.

The problem with the locking screw is it’s more of a wedge on one side. When you tighten the screw down, it pushes a piece of the hinge on one side outward. When it contacts the wall it moves the whole barrel in the opposite direction. Then it’s no longer aligned correctly. And exact alignment is critical – down to less than a millimeter in any direction or things don’t work. If the holes were exactly aligned and there were very little space around the hinge then it wouldn’t be an issue, but I had to enlarge the holes because the 8mm hinge won’t go into an 8mm hole.

So now there’s enough play it throws things off. I’m trying to stop the movement by wedging a toothpick in the opposite side. When everything looks good and works I’ll “spot weld” it with epoxy, remove the toothpicks and add more epoxy. Amazing how one little issue compounds and grows as you go along.

Regarding the groove on the side of the hinge that was mentioned and where a screw is meant to be used – in my research I found anyone who tried that had issues, i.e. finding a screw that small that wouldn’t break when screwing it in, trying to predrill while the hinge is out (can’t do that) or while it’s in, in such a small opening, was challenging. That is the groove I am using to stick a toothpick into. I may try a screw with a bit of wax, if I can find one small enough, and see how it goes.

All in all, I’m learning a lot in my first woodworking project in 30+ years. It’s challenging and that’s good. I also am learning to not get too ambitious too soon! I think these hinges will be put on the shelf for the next box project and I’ll come back to them another day.

Of course, your problem originates from the over sized hole. Are you sure your barrels are 8mm and not imperial measure? They are made to require a snug fit in the hole. Otherwise – the problem you are having. You need to figure out why the barrels will not fit into a properly sized hole. However, as said previously, the epoxy will work. It is just not easily reversible.

If it’s a SOSS hinge give them a call I’m sure they would know.

Good luck!

I have successfully used medium thick CA glue and also Urethane glue (the original Gorilla glue type). The urethane glue needs moisture to cure so moisten the surface of the hinge with water. Only a “very” thin coat is needed because it expands as it cures. Epoxy will do it too but is a bit more messy to use.

It’s not a high-end digital caliper but I think it’s reasonably accurate (see pic below)... In the reviews one post mentioned this issue. I didn’t think (there’s my problem right there) it would be a big deal to overcome. Hubris.

Not an SOSS hinge, but if I do try this later I’ll go with one of those.

Those are TAP-IN hinges. They’re supposed to have an interference fit. That’s why its knurled.

At this point, I would just go ahead with the epoxy and be done with it. Should be fine.

jb weld sets rock hard, I think that would be the best bet. I would rough them up with sand paper and file some light grooves into them, i would oversize the hole by 2 mm each side. most epoxies work best with some thickness to them, unlike wood glue where no gap is best.

crazy idea. set the hinges in a block of wood and the fit the blocks. It may be easier to clamp them an operate the hinges to make sure your happy with the motion, plane the blocks a little to refine the movement and then glue the blocks.
