- This video shows how to bend PVC pipe using boiling water and a jig to hold the desired shape in the pipe. This process was used to construct five rounded roof sections for the PVC pipe canopy frame on my raft
The take away here needs to be the method that this gentleman is GIVING us. Use it , appreciate it, or modify it to own needs or devices and be thankful that he shared it.
Exactly!
@@MegaKB33 Well thank you, at least two of us agree.
Yep; I hate when commenters get rude with somebody that's just trying to pass along good info to those of us that can make use of it! If someone doesn't like the video, move on to the next one and forget you saw this one! If someone thinks they know how to do it better, they should make their own video! Personally, I thought this one was terrific and will come in handy for me later this spring.
45 degree angle pieces cost much more what do you have more time or more money,also what if you had tp travel 100 miles to get supplies by the way Thanks for sharing
very true, excellent info here, i need to build something similar to make a protection for my orchard that hubby and i want to do with dwarf variety fruits trees, we got to protect them from birds, hot and cold weather ...this could be the way to go.
This video was great. I like this better than using hot sand. The jig was fantastic. Thanks for sharing.
Thank-you for the kind words. I have seen videos using the hot sand method and it does have its advantages; especially when making bends that could cause a pipe to collapse. The sand prevents this from happening because of the internal support it offers.
Perfect - David yr the Greatest ! * * !
@@Da175305M I like the got water idea. Makes great sense for longer pieces with gentle curves. Also, use the garden hose to put in cold water to push out the now not too hot water.
I haven't tried hot sand but I have used hot peanut oil (350 - 400 degrees). I'm not certain what temperature I can get the sand up to.
Nice! Your bending jig + hot water method demonstrates some cerebral activation. Just the technique I've been looking for to build a support for a tarpaulin in the narrow space behind my house. Lots of people have built hoop houses with PVC, but my idea is a modular structure which can be disassembled when I move to a bigger place. Looks like I'm off to the big-box store with a plan in mind.Thanks so much for sharing this.
Great process my man. For those with large pipe bending projects, I suggest adding a water recovery system (i.e. 5 gallon buckets, etc) to reuse the water.
David, thank you. This well made edited and sound/video was excellent.
Keeping things simple is always best. This is a very effective way to make constantly the same shape. And the idea is so flexible that other shapes can be made using the same principle. I thought you might use a heat gun to blow air through the pipe but hot water seems better.
*Nope, too complex. Hot sand works a lot better making this arduous process effortless:* th-cam.com/video/p1SMOPaajgY/w-d-xo.html
I've made large sweep elbows with 21/2 inch pvc. I used 2 salamander heaters pointed towards each other. Your right about the noodleing, it can get beyond workability easy. For what i was doing i couldnt form it like you did. Maybe in phases. I went a full 90 degrees bend, 3 foot sweep. But I've never thought about boiling water. Ultra simple. Thanks for sharing
This is awesome! Your video came up randomly and I am very happy I watched too. I've been racking my brain to come up with an idea to cover my wood. Now I know how to bend PVC pipe for a frame. Thank you!!
Great information and good demonstration of how to do it. I was getting a little "tlpsy " while watching your video, much like trying to get back to the ship after a night of liberty in a foreign port. Hopefully I won't wake up in the morning with a massive hangover like I did those days after a night of liberty. Great information. Thanks for sharing.
That is a lot of thought, planning and work you did on constructing the table where you bent the PVC. Good job!
How lucky I am that this video popped up randomly. I WILL be using this as a skiff shelter. You just saved me an ass of $$$. Outstanding Sir!
Phillip Same thing happened to me, random video that’ll save me money!
Brilliant! Fabulous idea! Thanks so much - I love that it's so practical and easy to do.
Great video Bud, will prove very hand for my trailer at camp, the awning is on its last days. Thanks very much for taking the time to do the video, very useful.
got a kink in mine with the hot sand and heat gun. maybe I didn't have enough sand. I was excited when I saw the long heaters you can put in them until I saw the price.
Your project looks awesome.
Nice! I did the same thing with PVC years ago, and was even able to use the bending frame for conduit, the thin walled electrical pipe. The PVC after 1" in diameter needs a bit of heat, so I made a heat box that was open on the bottom and used a small BBQ to heat the plastic pipe. I had elevated the open bottom box enough to not over-heat the plastic pipe. After an hour I would check the box and remove the BBQ to let the plastic pipe cool. This is pretty easy to do since 1" inch PVC can be curved a bit by hand, but needs the heat to take on the curve as a permanent shape. There are heating tools for PVC and the best ones seem to be those that fit inside, but you do need to ensure you use them to heat the pvc without overheating it and will still need a jig to control the curve you want the pipe to remember after it cools.
Great info David. I appreciate it. Might need to do some pipe bending, you never know what kinds of projects I will come up with. Also, I'm glad you got a tripod.
Another American craftsman. 50 years back every American man had a workshop, and was always building something after work. Diresta seems to have reignited a small blaze.
My workshop looks like it took a 152mm apers direct hit. I like it that way. Only I know here where everything is, and what is presently of focus. Good build, especially showing people the jig, and complexity required for accuracy.
Either you are single... or you married a good woman.
I have no idea wtf you are talking about!
I worked for many years at KitchenAid and had a very messy bench by a main door into the lab from the hallway. Tools and materials disappeared all the time from the neat benches and cabinets. Nothing ever was taken from my messy bench until they forced me to clean it up and label everything. It was empty in about a week.
My workbench looks like you'd expect a mad scientists lab to look. In complete disarray - but I know exactly where everything is ... except the cat ...
Good demo and method, lots of applications. The raft race looks like a blast!!
That's awesome. Opens up many project ideas. Thanks
Very similar to my jig I made to steam bend HARD MAPLE (1" thick) for the edge banding on a countertop. There's calculations of how much overbend to use (since wood will straighten a bit when taken out of the jig), and how long to steam the wood (I used a 6" diameter length of PVC with dowels inserted through it to support the wood yet allow the steam to make maximum contact, with the steam rising up into it at midpoint and traveling towards the two ends. First piece of wood snapped, but the second took the form and came out great for the countertop. Fascinating thing is that hard woods actually steam bend easier than soft woods, because of the nature of the grain...
Thank you for sharing this. I am definitely going to use this method to make a cover for my pontoon and to build a greenhouse.
Simple engineering at it's finest. Great project and I am happy you shared. Thank you!
Great video. I wasn't even looking for anything close to this application, but watched the whole thing anyway because it's well explained. Good job! 👍👍
LOVED IT ! Just goes to show ya , "where there's a will , there's a way "
The way I heard it was, "where there's a will ... there will appear 50 relatives no one knew he had."
or relative
Where there's a hole there is hope !!!
BRILLIANT yet so simple. That's the best part of your procedure, Mr. Malboeuf. It's simplicity. Many, many years ago, I constructed my 1st C-Band satellite receiving system myself using 1/2 & 3/4 inch EMT conduit for the framing ribs of my dish. To get the same, consistent curve for each stick of conduit, I curved them over a left over roof section or 2 of a large, steel Quonset type hog shed I helped Daddy build. Although it wasn't too hard to make all those identically curved sticks of conduit, the finished assembled structure of the dish was much heavier than I expected it to be. Even though I used hardware cloth & screen wire for the signal reflective surface of the dish, the combined weight of all those lightweight, thin walled sticks of conduit, again, ended up being much heavier than I expected. I'd thought of & would preferred to have used PVC, but was unable to think of a way to curve it & to keep it stay curved (I built it in the mid-80's). If only the internet & You Tube were available back in those days. Thank you, Sir, for these very informative & again, ''so simple'' instructions on how to do something I've still been wanting to do to this day. I've accumulated a large amount of various drawings & plans for curved framed, PVC structures both drawn out on paper, as well as in my mind that's been in my possession for decades. Thank you again, and take care Mr. Malboeuf.
While in college many eons ago, had a job stringing copper and/or pvc pipe for pneumatic controls over hot industrial furnaces. Learned a lot, quickly.
8kg hank you
WOW!!!!! I am super impressed! This is EXTREMELY HELPFUL!!! Thank you!!!
Outstanding! So creative! Lol! I love 🤩 the jig you made. I couldn’t afford the $2000 dollar curved curtain rod so I used light weight pvc pipe, painted & glued ends . It’s really informative to watch your method, thank you for posting. Smiles
I live in the tropics where, if it is not raining in meters - the sun is almost cooking you so ever since leaving the so called "education system" when I was 15 and into the "university of the cold cruel world" I have learned many new skills and this is one of them. Just goes to show that even in my late 70's I have learning something new every day, even from this youtube channel and this is one of them - just another skill well learned from another's world experience.
Thank you for sharing
I was looking for a way to do the same thing to my pontoon. Great idea i think i'm going to tray that. Thanks for the video.
Great job David. You are talented.
Your system is Extremely Effective! I have been looking for a Good Way to Bend PVC... This is it! Thanks so much!!!
I'm glad you have found my experience and technique useful.
You're a pretty smart and resourceful fella. Thanks for sharing.
Great job. I enjoy thinking things through and getting results. This shows that you are a problem-solving ninja!
Thanks!
Spend an hour to make a jig, and then a lifetime of looking at consistency. Beyond patience, this is probably one of the most important facets of performing a quality job that can often be better than what a professional would and it overlaps all projects. Good job on tactics.
Genius! Great ideas, thanks for sharing.
i would love to see how the finished version turned out. Great video thanks
Great idea, would love to see finished product. Good idea for a DIY covered dock
Brilliant, you just solved my problem, as if you knew I had a problem, thank you, God bless you.
Sometimes a random idea becomes the answer to a question you don't have yet.
Thanks for sharing your techniques. Pretty cool.
I like your Technique and the fact that you shared your mistakes is very helpful. cheers
Well done.
I have a lot of these sends to do. I'm thinking of using nylon cord and pullies to create the bend.
Well done and explained. Also dangers that exist and precautions.
Thanks for the education. I have a similar project to do that I have been engineering in my head for a week or so. Now I know! Suggestion for you , "Run a pipe down the middle at the top for rigidity". Dr. D
Your shed looks great! Thank you for sharing your knowledge with us! I built an 8x10 shed for my kids in my backyard earlier this year using plans I got from *WoodBlueprints. Com* Clear directions and an accurate materials list...It was great for a novice builder like myself!
Great job ! I worked in hydraulic fluid systems for 4 years up in Canada . This is the same technique we used to mfg fuel line , power steering line , heater lines etc .

this will be the best sail you've made yet!
Nice job. I convert canoes into sailing trimarans. For transporting my rig and camping gear to the water I used a small boat trailer and put a flat bed on it with a double bunk for the canoes. Your idea has merit, and if you don't mind, I'd like to do much the same thing to convert the trailer into a small on-the-spot camper. Also, I can see a version for converting the trimarans into on-the-water campers as well. An 18 foot canoe, with outrigger struts 6 feet apart will make a fine platform for a cross thwart shelter.
Thanks, great job Dave. - You need to show us the *after* with the tarp over it too. :)
Very good David, thank you for sharing!🤠
If you're doing a tiki bar type themed setup, you can take some 1-1/2" or 2" (pick your size) PVC and mark it every 12" to 14". Take a plumbers torch and heat around the PVC at a mark you made on the pipe. Went it heats up after a few seconds, you can push the PVC pipe downward and create a slight "bubble" or ridge around the circumference of the pipe. Do that to each mark you made. You can then stain the PVC with some brownish/green clear stain or use the torch to discolor the pipe. When you're down, it will look exactly like a piece of bamboo.
That was really well thought out. Thank you for sharing your ideas.
Cool
I use the same form techniques as a cabinet maker. A few weeks ago I made a front paniier rack for the fromt of my bike. I heated the pvc over a propane grill as I only needed to bend short segments. Had sand in it and bent it around the template. I inserted dowels where the support tube met the angle bracket and epoxy and screwed it to expand the dowel like an anchor. I will make vids as soon as I replace my stolen cameras.
Very nice job! Don't need the info, but you never know when it might come in handy. Thanks for the effort you put into the video
I'm always glad to share my experiences. I'm hopeful my knowledge can help folks with their own projects.
Love this video. Gonna use this idea to build a geodesic dome.
great jog! thanks much for your idea ,I'm thinking one can apply this to many projects!
Exactly! It seems that there are way too many people in this world that dont have anything better to do with their waste of a life than gripe about something that they most likely have no clue about..they need to get out of their mommy's basement and get a real life! I love this video it is extremely helpful to me! Thank you for taking the time to make it.
Your welcome!
Brilliant! Nice work, thanks for sharing.
Good video man...I have a project I am going to try...so.. thank you for the info...it is appreciated
Very cool David. Thanks for sharing...
Now I know how to build my greenhouse frame. Thanks for the video!
I agree
I had a 20 foot 3/4 pvc that I wanted to make a circle hooking it back into its self in the winter. Every time I just about got it itwould start to crack and squeak so I laid one end in my tail pipe for a few minutes and boom it went rite together
I made a pvc greenhouse a couple of years ago - one thing that really added extra stability was cutting the arches at the center top and adding in a plus shaped fitting. Then connect both sides of the arch into the plus so the the remaining two connectors point toward the rafters on either side. The cut short straight pieces and add them between the rafters. This really stiffins up the roof when putting a tarp or plastic over it. On the 2 end rafts just use a T instead of a plus.
Good job! Learned a lot from this video.
Good job. Helpful for a lot of folks.
Awesome process. Well thought out.
Well done... I didn't think it was going to work but it works very well.
I didn't use the 45 degree elbows like you did. Instead I used the next smaller size pvc to make insets after finishing the bending process to join to straight pvc for a greenhouse frame project. That way the joint is smooth and has no lumps, or bumps. I didn't use hot water, I used hot sand. One reason is because it holds heat a bit longer and can be used over and over again. Pretty simple solution since a metal pan from the thrift store worked well to hold the sand until it got hot on the BBQ and the BBQ doesn't need to be huge either. I also discovered it is possible to use conduit inside pvc pipe to stiffen it and the pvc protects the metal pipe, extending its useful lifespan. PVC in strong wind tend to flex a lot, which makes it hard on the plastic sheeting on a greenhouse that needs a stiff frame to prevent stretching/warping of the sheet plastic.
People also make forms like these for pool and hot tub covers, nice jig set up..... keeping it simple and cheap.
Very smart project!!! Congrats!!!
Clever guy, clever idea, great jig.
Thanks Dave! I will be working my own green house some day and I saved this video. I am jealous of that catamaran though.
I'm planning to put together a video of my catamaran to share with my followers.
So simple, yet so ingenious
Awesome David! We could use this info for a "high-tunnel" greenhouse, a chicken coop, a car garage, whatever. Am sharing!
Thanks! An on demand water heater system modified to HOT and a 12 pump to cycle in a loop is the upgrade.
Your table is an abstract art masterpiece!!!!!
I hope there is no breeze out on the lake when you take her out boating but it may be fun when flying. You would make an awesome neighbor. Love your video dude.
There is always a breeze out on the Connecticut River where I use the raft. Luckily there is less windage from a curved roof then if I had gone with a 45 degree roof. Maneuvering is a bit tricky in a strong wind no mater what kind of canopy roof shape is used. If it was necessary the canopy fabric can be quickly removed if the wind got too be too much. One of my neighbors is a carpenter, he gives me free wood scraps and doesn't mind my carpentry noises or activities. Heck, we both build stuff outside all the time and get along just great. My other neighbor tinkers as well and is a first time homeowner. he's been building his own workshop in the garage and doesn't mind my projects either. I share any extra materials and tools with him too so there is that to keep the neighbor relations happy. I'm lucky to have awesome neighbors as well.
Clever! Nice looking work!
Pretty crafty sir! Cool video!
You are an everyman making it work, and, getting it done..good job
Cool video...I learned a great way to shape PVC for my future small car canopy to cover my 1994 300ZX convertible...I'm thinking of keeping it small and collapsible, then putting rollers on it, to move it about...Get out of the car, open it up, sort of like a convertible top, you just pull open, roll it over my baby and walla, protected from sun, wind and rain..My thanks to the gent for making this...Wish I could see the craft in water...
Best laugh therapy I’ve had in a long time!
Yer mom.
At first, I thought you were making a greenhouse; good idea.
Excellent information. We can use this knowledge on our little acre.
Well done Dave. Good approach I could use this for a simple glass house using plastic. I get pvc offcuts for free.
Thank you sir for sharing you good ideas, very interesting and instructive video, keep thek coming
Thank you for sharing this idea.
Very smart idea. Thank you for sharing this video.
Your're very welcome.
Great work! I am an electrician who always looks for ways to use PVC.
Pretty good idea. Thanks for sharing.
Nice build, simple way to form an arch.
Not sure if it'll help me out, though. My arch is going to be about 40Ft wide as I'm building a green house on an old house foundation, which is 45x70Ft. I think the length I'll be working with the natural bend will be enough. The sides will be solidly fixed so they won't be forced away from center. I'll have to have to at least 1 length wise rib, maybe 3. I'll see when things start to go together.
When I watch a build video for 'how-to' tips, I want info - quick and clean 'cos I need to get on with the job. This video is a little bit 'warts & all' BUT THAT is perfect. Quick info little time wasted for you [hampered by video making] or me. Bugger what the moaners say - if you want to spend more time polishing the video, you can, but this is often all thats needed. I found it very informative with no-messing. Btw If you put 4 or 5 little blocks on the former blocks, a single screw each so you can twist the block round and hold the pipe in place - like a cupboard latch, it would prvent the tube falling out when emptying it. Great video and a very handy technique.
If you want to do this with steel... different ball game. The old school method [no work table or bending shoes] is to pack the pipe with sand [to prevent wall collapse/severe ovaling], cap the ends, then heat it with a torch to bend it segment by segment to arrive your final custom curve with whatever you can find to apply controlled leverage - a hickey for rigid conduit works reasonably well, but use anything you can control [even a tree stump, a sledge and a block of wood can go far]. Try not to bend to a tighter radius than 8x pipe diameter as a rule of thumb, but it can be done as tight as 5x with extra care and the right amount of heat. You can chalk an outline on any large cement area as a starting template on the cheap, then match pieces. Once you like your shape, uncap the ends and flush it out.
Wise people, thank you so much. How do you join with the uprights, do you use a bigger pipe?
My dad built a dunebuggy in the mid 60's. I remember helping him fill the tubing with sand for bending. Worked well.
Well now I just learned something special. 👍I'll use this method to make a shelter for our snowmobiles and 4 wheelers hell yeah
Basically the same technique used for bending wood shapes using the jig block panel.
interesting points ,if anyone else trying to find out backyard storage sheds plans try *WoodBlueprints. Com* Ive heard some decent things about it and my colleague got cool success with it.
Pretty ingenious Dave
Great video and commentary.
Thanks Ken, it's nice to read that you liked my PVC Pipe bending project. I'm planning another project soon. I'm going to make a PVC frame for a privacy curtain to conceal a porta-potty on my raft. I'll be posting that real soon.
good job dude
Why not use a heat gun?
@@bjg77 A heat gun could overheat some spots and weaken them. Also, difficult to heat the underside of the pipe. It would take more time and physical labor holding the heat gun. Also the extra cost of electricity.
great video, but difficult to watch
a tripod and a remote mic would make your videos excellent tutorials.
thanks for doing this.
Amazing ingenuity!!!
with that jig, im betting you could get by using a heat gun blowing right through from one end of the pvc to the other. whenever i had to bend pvc for electrical work, i sometimes used a greenlee heating blanket (they are not long enough to bend a whole 10ft stick of pipe though), but mostly we used a milwaukee heat gun, i know that there is a spring that you can buy to slide through the pipe so that it doesn't oval out on you, but ive never used one. In a pinch I've even bent pvc by using a halogen work light. its amazing how fast a heat gun gets the pvc bent and how fast the pvc cools and holds the bend... sometimes you will see long lengths that people have run horizontally across buildings that sag because the heat from the sun coupled together with the weight of the wires inside is enough to bend the pipe.
Thanks for thoughtfully including the temperature
Wish you'd have included the name of the "bulkhead adapter" of a web link to the source.
Thanks again
Suggestion, get a steam generator such as a wallpaper remover. You don't need to move the table.
Just leave the steam on for a while until the pipe has set itself.
