PVC Pipe Bending

hi my name is Dave and I'm here to teach you how to do some PVC pipe bending if you look in the background you can see that I've done four already and I'm getting ready to work on my fifth and final one so I made a jig to hold these bows the way I want them and before I put the pipe on the jig I had to glue them together I'll show you that over here now here's the pipes that are already glued up I have an angle a coupler of about 90 inches of PVC and I have the same kind of fittings on the other end and what they're going to do is they're going to engage these uprights so this has to be symmetrical so what I'm going to do now is bring this over to my my jig that I built and this is an old table with some chunks of 2x4 a strategically placed it's going to hold this thing and you'll see there's a hole right there I'll explain that in a minute on these rulers I just hold it up a little bit off the table so when I apply the heat it just stays on the pipe and it doesn't get transferred to the table so what I'm going to do now is I have to engage the very beginning of this in there and I'm going to have to put the camera down a second to get this started so hold on a second so very tight fit and there we go I got it started okay so you can see that it's ended the start it's in these blocks now as I go around I have to push it down this is a little awkward to film okay you can see how I'm in in these and I got to come all the way around this it takes a lot of force to bend his pipe some more here here we go okay so now I'm in this jig all the way so this slot simulates a the position of one of the uprights and measurement from the center of this over to the other one is eighty nine and a half inches so that's senator center mounting distance and what I did was I when I first built this I put the pipe in without any of these blocks it just found its natural curve and I buttered these 2x3 chunks up against it and screwed a man you can see that this is up a little higher this is so that the heat from the pipe doesn't transfer to the table and kind of Wick it away and also the same thicknesses these this coupler so if you look down the height this extra height here is equal to this thickness so this pipe is sitting nice and flat and it's not going to be twisted at all so the key now you want to know what this hole is for well that's so I can insert a funnel and put boiling water in this pipe so what I all didn't need to do with this table first of all is I got to stand it up so I have a level on this so that when I when I tilt it down let me come around here you see this level it's just about level so this means that the when I put the water in it's going to fill this thing up evenly and it's not going to favor one under the other so now I have to clamp this up and put the funnel on hold on I'll show you that okay so I got this clamped in now you can see this this is just retaining this so it doesn't fall out my first lawn I actually had this up over this piece here and because it was sticking up a little bit it squished it and oval eyes dit and I had to play around with it to get it to fit so anytime you're clamping the PVC don't clamp a higher surface that will interrupt the the mating surface I also clamped a funnel and I put a screw here so this funnel doesn't flop around if we're dealing with boiling water at 220 degree 212 I think it is yeah on PVC pipe ideally should be bent at 170 that's what I read on the internet but 220 is good because I figure as soon as I pour this hot water in there the cooler pipes going to wick some of that heat away and I'll end up close to 170 keys I'm restraining it completely so this thing can't get can't do anything funny here's the other end so when I pour the water into the other end I also got a hole here when this pipe fills up you'll start to see water coming out of here so then I know the whole thing is filled up so P key here is to do this in the area where you won't get burnt and spill hot water on anybody I'm going to go in the house and get the water something to keep in mind is if you got a cat get the cat in a different room so it doesn't walk between your legs and trip you and have you spill hot water all over yourself wear gloves just be very careful I'm going to put this down I'll go with okay it brought out my boiling water I'm going to use a smaller pan and I'm going to come over here and I'm just going to pour it in so I'm just going to keep doing this till this pipe fills up and I start getting water coming out of the ends you can feel it when it's just about there you'll get that watery acoustic that just coming to the top okay so I've got water coming out of the ends now I want to look at the back of this thing I use the subscrube old it in so if you're using longer screws just be careful that you're aware that these are sticking out and it could stab you in the knee but I'll just use an old table some chunks of wood you pretty much got a the first one you do is your experimental part so I would say if you got to make I had to make five of these I should have had enough materials for six in case I messed one up but it turned out I was able to recover from that one that oval eyes the end so once again I got the level the table is sitting level so this means the water is going to fill the pipe up equally so what I do is I set a timer for about 15 minutes just let this sit and sometimes you can hear it creaking as it adjusts the pipe is very warm it's not burning hot but it's holding it but this pipe gets very soft if I just take this off right now we'll be like spaghetti so I'm going to light wait 15 minutes and then what I'm going to do is knock the table over get the hot water out and then I'm going to take this a gallon of cold water and pour it in there next and that'll cool everything off and set the form so 15 minutes I'll be right back just it in about 15 minutes I took the clamps and the funnel off now what I'm going to do is I'm going to push this table over so that I can drain the water out of the pipe so I just tip it up like this you can see the water kind of ran out of both ends here and I put the table back up there we go now we're back up here put this came out so we put the cold water and make sure it doesn't come out of the form I got my cold water I already took the funnel off but I can just shove it back on okay this is a little awkward on a filming aspect but here we go so now I'm putting the cold water in there and this is still in the form so I just keep filling it up the water comes out the ends go so I know I'm full just side it away okay so now I'm going to just let this sit for about five minutes cool off that'll lock this the form in and then I'm going to yank this thing off the form and you'll see how nicely this works okay five minutes is up now I'm going to do here is I'm going to pull this thing out of the form and let all the water out now you can see on the latest on the ground perfect so it kept goes the shape that I wanted it to exactly and now I'm going to go put it on the canopy frame here's the end result I made five frames on my jig and now I have a curved roof so when I put my tarpaulin over this on my raft here the water can drain if it rains out last year I had a flat roof and the water collected and uh it practically collapsed this whole frame so now that this is round the water will be able to shed I cannot leave the cover on overnight and if it rains out no no worries I still have to make some height adjustments some of the uprights got to be cut down about a foot I got a little extra height there because the boughs were taller than the flat roof but this is a much much better arrangement here's some final food for thought this is the engagement of flan part and the the - what happened on one of them was just got oval eyes because I had clamped on it and what I was able to do was take a heat gun and kind of stick something in there and open it back up and make it round again it got it close but no it wasn't exactly a perfect fit so what I did is I was able to open it up even more with what I did was I took a piece of sandpaper and see how I put it on here so it was just a little piece of it and is able to work it in there this is awkward filming by myself what I would do here see if I can show this is I was able to engage this in here and kind of run it back and forth and just sand this a little bit bigger and get it smooth because there's like a little rough edge here and that that made the fit even better so don't fret if you squish something use a heat gun and you know work it back open with something I took another pipe and shoved it in there to make it round but it's it's got memory so when you pull it apart it's going to spring a little bit back just take a little sandpaper clean it up make it smooth and you can recover that way it's always easier to just take a little more material off than it is to try and bend it and force it it's kind of like whittling you got to kind of work at it to get the fit you want and that's just a little tip another thing is PVC pipe oh it's a very easy work with very easy to cut little common tools ten foot section of this stuff is about three four dollars where if I use metal conduit it's close to ten bucks a section so plastics much easy to work with you can use PVC glue so it's together real quick if you make a mistake it's fairly inexpensive to do it over again you can always cut pieces of pipe out and use couplers to make it back up again but if you wanted to go with steel I'd say make one out of PVC first to get everything the way you want it and then you can know what you need to replicate in the metal tubing when you're on a boat a metal canopy is probably bad for lightning strikes but PVC is uh does have some static to it so probably would I don't know if it would cause any trouble what I had down here are the basis that this plugs into if you use these leave a little airspace in there so when it rains out this can dry out under here what I did was I put some washers between this flange the deck to just boost it up a little bit and underneath the deck is the plywood it's screwed in there and a lot of different places I actually made some six six mounting holes there were three big ones for lag screws the decks quarter-inch plywood so how to go easy use appropriate fasteners these that got online of about four dollars each so there's ten of them so the cost isn't too bad for a homemade canopy this all comes apart the lower rail comes off then this upper rail comes off and then these bows come off so everything breaks down and I can travel with this thing everything

great video, however difficult to watch a tripod and a remote mic would make your videos excellent tutorials. thank you for doing that.
