3-jaw rivet guns? (or: "Ping Andy Dingley!")
 

I asked the query below tagged onto the bottom of an old thread, which
may be why it got no response, so I'm trying again in a new thread (and
x-posting to URCM too!)

Having looked around, all the rivet guns I can see appear to have two
handles (like a crimping tool) with a round nozzle for the rivet at the tip.

Can anyone advise please? Many thanks.

When buying a pop-rivet gun, get a 3 jaw design, not a 2 jaw.
There's an extra size increment you can have, just from the grip, let
alone the effort needed.

Thanks for that advice Andy: now, as a total rivetting numpty, is it
obvious whether a rivet gun has a 3 or 2 jaw design? Never handled one
before. What about the Screwfix one which I cited previously?

If you have access to a compressor, beg/borrow/steal a pneumatic one ;)

Watch your fingers with those blasted things.

That looks similar to my "Fuller" pop-rivet gun. If you remove
the round nozzle you will be able to see the jaws that grip the
rivet. Mine has two jaws and that is OK for the small amount I
use it. For long rivets I have to press the handles together
twice. I assume that a three-jaw gun would handle bigger rivets
and be able to rivet in one operation. But then it may not fit in
confined spaces and would cost more.

I use a two jaw one for occasional riviting (like once in five years).
I can't really see why three jaws would be significantly better than two.
They only have to grip the shank while you set the rivit.

In that case, the rivets must be too long. To judge how long the rivet
shank should be, take the thickens you are riveting and add just a
little over (10%) the diameter of the rivet to the length. That way, you
get a good rivet set.

I have never encountered a three jaw gun in the aerospace industry, so I
can't comment on them.

Speaking as an aircraft engineer, most of our pop pliers are the
standard 2 jaw. Lazy tongs are 3 jaw.

The pop pliers have a small range of rivet size options in terms of
dia, or you need to change the jaws. The lazy tongs take a far greater
range of rivet mandel sizes with the same jaw.

Most pneumatic pliers are also three jawed

No. Look up the snout and count them, but you have to look close. I
think "Beargrip" are the commonplace brand with the good grips.

Most cheap ( £20) hand riveters have nose bushes for 3,4,5 & 6mm
rivets. You have the hand strength to pull a 6mm aluminium rivet with a
simple short-handle riveter, but the cheap 2 jaw tools can't get a good
enough grip on it. A 3 jaw one can. Bigger riveters, such as long
handle or lazy-tong riveters generally have jaws adequate for the task.
