If it's a steel frame, you can just have it brazed back in. You might want to post something in the framebuilders section of the site and see if anyone there knows where you can get it done in your area.

Is it a braze on? It may be a rivnut! There is a way to tighten a rivnut if it is loose. A picture would help.

usually for the bottle cage it's just a threaded thing inserted into a hole (like a spoke nipple but larger), it can be glued in place with some epoxy or soldered or brazed. But for such a small thing epoxy works.

I've glued two regular nuts on a frame that didn't had holes for the bottle cage and stand fine for several years (i had stripped the paint for a good gluing though).
But if you have the holes and have the threaded nuts that fits in that holes, then almost any glue even superglue might work, but I'd recommend epoxy (two component like Bison Epoxy)

Pretty cool way to fix a loose braze on with a QR skewer

the QR is for removing the rivet inserts, not for installing (installing can be done with a rubber mallet)

Wrong. If it is a loose riv nut, which is held in place by being expanded when compressed, like a rivet, then the QR trick can be used to try to get it to expand. If still in doubt, click the link and read the how to from Park.

Except it only works for "riv-nut" type cage mounts, not actual braze-on mounts.

Which is why I wrote this: "Wrong. If it is a loose riv nut, which is held in place by being expanded when compressed, like a rivet, then the QR trick can be used to try to get it to expand. If still in doubt, click the link and read the how to from Park. " in the post above yours.

Assuming a riv-nut the Park tool method works. I did it with a loose bottle cage "braze on" on Ten Wheels Cannondale tourer and it is still tight.
