Oh. So you can post a link -- great. I'm waiting for it.

Setup time with no moisture is quite long. A puddle will stay a

thin in the presence of moisture, or in some cases alkaline substance,
it cures very quichly. Baking soda sprinkled into a drop of CA

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.

Joe Gwinn


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.

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 :-)

Hardly an urban myth.

Is it not interesting, that something which sounds like "an urban
legend" - must be fiction? That it could not have happened, because
err, ah, well, everybody knows it is a myth.

Like the existence of "Smart" US Army 2nd Lieutenant. I have to
take the word of two witnesses (One a Retired Sergeant) of just such
an occurrence. SO there was - at least the one time - a Smart US
Army Second Lieutenant. And a Harvard man, if Sgt Armstrong is to be
believed.

But it appears to be a very dirty trick that has managed to survive to
be occasionally played on the helpless.

Yep. I heard it put once, that Sea Stories" heard second hand,
are retold because they have some "survival lessons". Like the guy
who fell out of the bosun's chair, due to exhaust and paint fumes.
Landed in the whale boat. Broke his nose (and arm). When they
unpacked the cotton from his nose, it hurt. A lot. And he said "let
me catch my breath" but they grabbed the packing in the other nostrel
before he could. He passed out from the pain. Woke up as they waved
smelling salts, and answered some questions and then dutifully signed
his name where they told him. Then is when they explained that he had
broken the one corpsman's arm and the other's cheekbones when he
grabbed them. But he was deemed unconscious, so ... no charges.

There is a lesson there, for those who have understanding.

Go not to the Net for answers, for it will tell you Yes and no. And

Given that information it sounds as though those who squat on toilets
seats with puddles of unspecified liquids on them are in danger.

Are dirty toilet seats preferred seating among certain classes?

I want to try soldering some aluminum plate (0.032€�) onto each side of a
brass cylinder. When trying to solder aluminum in the past I failed.

Famously, Al quickly acquires a tough oxide layer of Al2O3 in air, and
nothing solders to that. There are ultrasonic iron tips that break up the
oxide so quickly and thoroughly that it can't reform before the solder
gets to it, but they are too rare and pricey.

I actually had success with the method I heard about here long time ago:
cover up your soldered area with light oil (engine/turbine) and scratch
the aluminum surface vigorously under the oil with steel brush or a
scraper, then apply hot iron loaded with solder. I used regular SnPb.

Crazy glue cures pretty fast on skin.

As for the glue on seat trick, it's pretty old, but real. I first heard
of it in the late 1960s when I was a summer hire at RCA, where we had
Eastman 910 (the original cyanoacrylate glue, still under patent and so
crazy expensive).

It was a big novelty then. I worked in the Plastics Lab, and people
would wander in and ask us to glue their fingers together, which we did
after explaining how to undo it without damage.

The nasty trick was to leave a small puddle on the chair of someone
disliked. Worked instantly. The remedy was acetone. Never heard of
this being done to a toilet seat, but the extension is obvious.

As one who used super glue by the pint in three grades I can say
that it cures based on moisture or difference in chemicals.

The thicker the solution is the slower it cures. The water type is
fast. Hit it with a mist or mist one part - glue on the other - and
mate them. Almost instant.

The skin has lots of moisture. Super glue was developed for field
surgery. Instant glue together a wound or seal a vein...

Martin had a former friend that was a large supplier of that glue.
