- How to do-it-yourself instructional on
repairing a broken garden hose hanger using a pop rivet gun. Shows pop-rivet
gun tip replacement, drill bit selection, installing and removing pop
Alright now hereís something that I know
is a common problem because I used to work as a tree surgeon and we were
often going into peoplesí yards and using their hoses to clean-up and
youíd find that the hose hanger was broken like this. So Iím going to
show you how to fix that using a pop rivet gun. And itís real easy. And
Fun. And itís fun because itís easy.
- OK so here it is a typical hose hanger and
of course this part has come off. OK there you go it was spot welded into
place. You know they just, I guess they didnít have their hearts in it or
perhaps it was done a robot or perhaps the heat settings were just too low
to make an effective weld. Screws that are holding it on the post, back them
off a little bit.
- You want to try and save money I understand,
you know I sure do, and so every once in a while you think ďwell I donít
use the tool very often so Iíll just save money and buy a cheaper oneĒ.
But the fact of the matter is I didnít save any money because I broke two
cheap ones before I shelled out for this more expensive model right here.
Whatís good about it is that itís got a steel stopper cast into the
- [Clicks handle]
- Alright, so Iíve got my rivet gun, itís
come with itís own little wrench, right here, fits in the handle. So
imagining I had to change the nozzle, which in fact I donít because this
is the right size, but Iím just going to show you, you know youíre going
to put on the wrench that came with it or perhaps your own wrench if you
have ring wrenches, those are the best of course. And this end you just want
to unscrew that. Thereís your nozzle. Trade it one of the other ones, say
in the handle. OK thereís the secret is you need to have the handle
squeezed shut in order to change the nozzle. Very simple, screw it down. You
want to add a little bit of tension too but that was it Ė you saw it. Here
let me undo it and Iíll show you again. OK. Again, you have to have that
handle squeezed down, and just add the tiniest bit of tension and thatís
all. And then replace the nozzle that youíve just changed back into the
handle immediately before you get back to work so you donít lose it. And
again just that tiny little bit of tension in order to make sure itís
locked in place. Yeah donít be in a hurry to undo this screw and figure
out whatís inside there because itís just a lot of very delicate little
wedges and springs that you do not want to have to try and reassemble.
Itís very challenging.
- OK so real quick this is exactly what a pop
rivet is OK. Not to be confused with the kind of rivets that they used to
put sky scrapers together with. Now that was something entirely different.
That looked something like this Ė this is not one of those rivets but this
is something like what it would look like. And you would put it, you know,
through two pieces of connecting steel and then mash the end of it down with
a pneumatic hammer and thereby it would be one solid piece, unlike say a nut
and a bolt combination that has a chance of coming apart, this is one solid
piece with an interference on both sides.
- Now the rivets on your jeans are something
else entirely, and of course, theyíre also rivets but thereís a cap on
either side thatís squeezed together. And I imagine theyíre put together
by robots with some kind of hydraulic pliers device.
- Itís basically a nail or a pin thatís
fitted into this Ė letís call it a collar, a shouldered collar. And the
head of the pin is rounded and the pop rivet gun accepts the stem and then
it cinches up on it. OK now Iím going to show you OK once itís installed
this is how a pop rivet works. OK Iíll just show you. Whatís going on
here is that the rivet gun is pulling on that pin. And itís pulling it up
and itís pulling it up and itís flaring out the other end. And so as I
squeeze the gun together, inside the shaft here are some spring loaded
wedges that are used to clamp on to the pin and pull it in this direction.
OK so weíre pulling on the pin and there itís starting to flare the end,
OK. Now, hereís the thing is you can see that itís backed off so in the
real world youíre going to have to move in on your work, push down and
accept some more of it and then squeeze and pull it up some more and when
you get to the end of your stroke, again youíve got this slack that you
need to take up so youíre going to be able to push into it like that. And
then pull again and eventually youíre going to get to the point where the
tension is too great for the strength of the pin and the head will shear
off. See the way itís all become distorted now Iím just going to the
last squeeze. Here we go and this is the one thatís going to shear off the
head so unfortunately itís going to go flying. And then of course, there
it is. Now thatís the shaft of the rivet I just showed you a second ago.
Now itís also worth noting that different rivets, even though theyíre
for the same size bore they have different sizes now that means that
theyíre designed to go through different thickness of material or perhaps
so after a little bit of digging around in my collection of pop rivets
Iíve come up with these three. Theyíre the biggest and the heaviest duty
that Iíve got for the job. So in order to select the correct drill bit
size, you just want to match it to the size of the insert. Keep in mind that
although itís counter-intuitive, I know people are constantly trying to
put this into the hole they drill, that is the wrong end. This is the end
that is held onto by the pop rivet gun and this is the end that gets
inserted into the hole. So weíre just going to match it up we can try
matching it up this way, see which one shadows, there we can see the drill
bit completely shadows the and you can see again itís pretty just barely
visible. So thatíll be a really good match.
- Alright well weíll just clamp this into
place for drilling have to do it on a piece of wood like that and hereís a
little tip when the wood comes up through the hole that your drill bitís
making, youíre already through. Just going to line it up, as I said you
see that wood coming out, you know youíre through already. OK thatís the
pilot hole, now weíll switch it up and do the rivet hole.
- OK and for the hook is the same deal we want
to do a pilot hole right on the dimple that is left behind by the old spot
weld. OK now so whatís left is dropping the rivet into the hole like that
and fitting on the rivet gun like that. And itís just a matter of
squeezing it, the rivet gun does all the work.
- OK well here we go these two on the ends
turned out great and this one I let go loose just so that I could show you
how to remove a pop rivet. Now Iím going to remove this one so I can put
another one on so I can get it nice and flat like these two are. You just
want to take a drill and put it right in the centre and you just want to
lightly cut away at it like that until you see youíve separated the rivet
cap from the rivet stem. And now that thatís done, Iíll just show you
the back here, this is what they look like on the back. See theyíre
expanded collars, expanded collar on the front quite nice, nice and smooth
not going to be any danger to my garden hose thatís for sure. So Iíll
just get one more. Again, drop it in, put on the pop rivet gun. Whoops.
Thereís a rivet stem still in this gun. There we go. Put on the pop rivet
gun just like that and bam. Weíve got three. Weíre ready to go and hang
it back up. Put the screws back on that hold it to the wall. See itís nice
- Where the spot welds broke weíve got three rivets now and
itís nice and strong, itís held on there good. Alright, we just throw up
the hose and weíre finished.
