I've got an old pop-rivet gun which worked perfectly well the last
time I used it, maybe 1978.

Bought a selection of rivets the other day and there is no grip. So
has the pin diameter changed with metrication? Or is my gun broken?

Presumably there is a spring loaded gripper pawl inside the rivet
gun. Maybe it's just sticking?

Have you got any original rivets to compare with the new ones.

There are several sizes of pop rivet - with different shank diameters.
The better guns have several nozzles, allowing you to fit the
appropriate one for the rivets.

But the nozzles just press on the rivet head, they don't grip the nail.

the rivetter must, or it won't do anything useful. As said probably a sticking mechanism.

Yup. Soak it in WD40.

Well a combination of factors but a good spray of WD40 followed by
some graphite oil once dried and lots of vigorous opening an closing,
plus shoving a panel pin into the slightly corroded nozzle and after
managing to get a couple of rivets in the whole gun started to smooth
up nicely - job done.

Thanks to all who made sensible suggestions.

They do have a connection with gripping, look at the taper on the end of
the nozzle it is in a different place for each one,the taper acts on
the gripping jaws

Yes the gun has 3 different nozzles.

Jeez I would never thought of that, I was using the left one.

Don't think they have changed - assuming the same size rivet. But on mine
the gripper mechanism is the same for all sizes - you just change the
nozzle. I'd check the gripper hasn't seized.

Nope, the one I built the house with in the very early 70s
still works fine with new rivets.

Yep.

Well the last time it was used was in Perth, WA so maybe it's an
antipodean thing.

Or I'll go for something seized/sticking.

Or splash the cash and buy a replacement.

In emergency can pliers/mole-grips work?

Pliers no. Mole grips plus nail puller I doubt, let us know.

Is it worth it given how cheap a new pop riveter can be bought for?

Nope, most of our pop rivet guns and rivets are imported.

I did initially thing that, but then I realised
that pulling the handle should have enough
force to close the jaws on the rivet nail.

More likely what used to move the jaws
closed when you squeezer the handles
has broken so that squeezing the handles
no longer moves the jaws IMO.

Or splash the cash and buy a replacement.

Yeah, they arent expensive. I've added some
more from garage sales just so I don’t have
to hunt up the original one when I need to
pop some more rivets.

No, you need a lot of force to pop the rivet.

Well, I meant worked when upsidedown!

But yes it is a Spiralux Model 2730 Heavy Duty Riveter bought from
McPherson's Ltd for $14.30.

I wonder if it had a lifetime guarantee.

Not sure anything did at that time. Pretty sure that came later.

No one ever takes much notice of me,if you have the wrong nozzle in, the
taper on the inside end may be holding the gripper jaws apart long
enough to slip, although the taper's prime purpose is to make it let
go,look closely at the design.

Nope. You have to keep the rivet up hard against the workpiece whilst the
shank is withdrawn.
BTW, you're lucky to still have that old gun; the most common Chinese-
made ones you find on the market today are total ****E.

You'll probably find that the "gripper" bit has got crap/corrosion on it preventing it from biting on the rivet shank.
Dismantle & clean up.
They grip a wide range of sizes when working.
