Solvent based adhesives need a porous material to work best. Adhesives such as "Goop" would have a hard time drying when used in a metal to metal situation. Epoxies or moisture cure adhesive like MS polymer and urethane based stuff works great on metal to metal and the MS polymer adhesives will usually peel off of the metal when you are done but won't let go unless you pick at it. Of course, we are talking about low load applications like sticking coins on paddles.

clicking the "stick stuff together" tab will give you a guide to what type of adhesive to use in most situations. Of course, none of these are tuba related, but a good guide to common household repairs.

not only will I not Poo-poo this I will confirm that it can happen also with large amounts of epoxy (one of the chemists set the hood on fire by mixing a large amount together in a 1 gallon can to cure it for disposal). They laugh at him to this day for doing it.

Don't think it was the aluminum, Joe. Criminal investigators do their fuming by putting the super glue in an aluminum container--it retards polymerization. And they even heat the stuff.
But if you had a cotton rag in that dumpster, that may have been the culprit. Super glue reacts with cotton very enthusiastically--which is why you shouldn't wear cotton gloves when using it--you'll likely end up burning yourself.
Matt... Where did you get the information that Superglue releases vapors when heated? I usually pay pretty close attention to the MDRS's and I didn't realize Superglue was hazardous in any way after it is cured.

From the MSDS link posted above (answers both Joe's and your questions):
SPECIAL FIREFIGHTING PROCEDURES Fire fighters should be equipped with self-contained
breathing apparatus to protect against potentially toxic and irritating fumes.
FIRE & EXPLOSION HAZARDS Cloths used to wipe up spills may cause rapid polymerization that could generate sufficient heat to ignite the cloth. Combustion will evolve toxic and irritant vapors.
Google is a strange thing. Here we are, in so many words castigating the use of super glue for instrument repair, and for good reason. In the meantime, as I pull up this thread, on my screen, google has provided several adverts for places that sell or provide industrial super glue services! Typical.
