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 rivets.
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.

Hose hanger with hose   Pop rivet gun nozzle change

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 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.

Comparing drill bit and pop rivet sizes   Drilling out / removing old rivets

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 more layers.
 OK 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 and stable. 
New rivets and a job well done
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.
