I've seen riviters working on F18's at Boeing,
and it sure appears to be a
higher art form. Not sure it's something I could do, but thought I'd ask
here. I've seen all kinds of rivits - different sizes - on an H960 I believe
there are a couple? Anyways, what tools are required, where can one get
rivits, what different types are there, and is it something a neophyte like
me who has never done a rivit before can do? I'm looking for the basic intro
to replacing a rivit for someone who has never done it.
There's a type of rivit called a pop rivit that I've used before. I get the
impression
that it's not as good a the sort used in manufacturing, but for this kind of
purpose, I'd think it would do fine. The basic tool is a squeeze handle device.
You take a rivit that has a shaft running trough it similar to a finishing nail
with a bulge on the inside end of the rivit. You put the shaft into the riviting
tool and insert the rivit into the hole. When you squeeze, it pulls the "nail"
inward and the bulge streches a cylindrical part of the rivit pressing it against
the back side. Then the tool cuts the "nail" and the two pieces are tossed.
What's left is the rivit pressed in place. I think most tool shops carry these
as well as supplies of the rivits.

Is rivit a US variation or a typo? (it's 'rivet' this side of the pond)
Anyhoo... agreed that for this kind of work it should be fine. The tool needed
should cost virtually nothing (I'd certainly expect it to be less than $10US)
and is really easy to work with.
Places like Halfords and B&Q will sell them in the UK (along with better tool
shops too); in the US Home Depot almost certainly have them and probably
Wal-mart too. Same applies to the rivets themselves.
I've always wondered how the massive rivets on ships are put in, in particular
how on earth they get them to also be watertight around the hole!

They are more-or-less forged into place. They are heated until they
are red, then hammered into place. The hammering action forms the
shape. A good rivetter was very valuable, as it was a artful skill,
being that he had a very short time to do a perfect job, hundreds of
times a day.
If you do not care what metal is being used, copper rivets are easy to
work with and form, using a ball peen hammer. And lots and lots of
light hits.

They're put in red hot and when they cool they contract and pull the
plates tightly together. In modern times the heads are hammered into
shape with a pneumatic hammer, but in older times it was 1, 2 or 3
men swinging big hammers - I've watched both methods being used!
Incidentally, my mother was a rivetter in WW2, she made Spitfire wings
at Castle Bromwich, Birmingham - mostly left wings IIRC.

It usually is on this side, also.

Pop-rivets are available in various sizes and materials. For this,
aluminum would probably do.
There are also "riv-nuts", that leave a threaded hole down the middle when
done.

"Real" rivets require access to both sides, and are beaten against an
anvil. For some uses, "real" rivets are put in red hot, and tighten up
more as they cool.
