The best for gluing steel to brass (which I do most often) is
Household Goop.

I'm pretty sure it's a chemistry issue. For such things, one asks
the
glue manufacturer. If I recall, brass is the problem.


The glue manufacturers I asked did not have a dicky. Indeed brass is
the problem. It does not matter how you pre-treat it. Incantations
and
saying Lord' prayer backwards does not work either.

Just Goop.

You saying BRASS is difficult to solder?????

No, glue. I think the zinc reacts badly with some kinds of adhesives.
Aluminum has this problem too. Anyway, there are glues that work, and
glues that don't work.

There are techniques that work as well, not just adhesives.

For instance, for aluminum...
The problem is that aluminum grows an oxide layer is just a few
seconds.
So what you have to do is prep the oxide layer and bond to that.
Phosphate wash followed by two-part primer like EpiBond or Randoplate.
Now your glue can bond to the primer and get some adhesion.

Urethane glues will actually work with the primer, Looks like it
dissolves into the primer.

But for general bonding metal to metal, pick a Goop, any Goop,
and stick with it.

How does this work for people to metal?

Cyanoacrylate. Glues people to almost anything.

Had a case of that yesterday over at Kern Medical Center. Woman went
into the rest room, dropped trou..and parked her ass on the
seat.....which someone had doped nicely with super glue.

She sat there for some time..then tried to get up...after some further
time..she started screaming for help. It was even further before anyone
heard her. Fire department came..tried various things..nothing
worked..seems the lady was a bit obese..and they were having trouble
getting solvent into that lard/seat interface..so they ultimately
unbolted the seat, flipped her on her face..put her on a gurney and took
her down to the ER..where evidently they got the seat off..some 4 hours
later.

Reported on the local news..to great snickers and hands over mouth.

Here's another Gunner confabulated story. This incident happened in a
Wallmart in Monticello, Kentucky, nowhere near Kern County CA. Google it,
there are thousands of hits. Funny that none of these I found mention the
particular details of unbolting the seat and flipping her over. These were
made up for purposes of good story telling I presume?


If I remember correctly, the first time I heard that story the ass on
the throne was the NCOIC of the Missile Assembly Shop at Udorn RTAFB,
Thailand in about 1971-2. The other details have remained almost
exactly the same though.

An urban myth perpetrated down through the ages :-)
