Could you share with us which brilliant course(s) you used? I assume there are plenty and not all do the same. I wanna have building cheat codes via math knowledge as well.
I'm just about comfortable with algebra again, then I'll be tackling trigonometry and calculus. They have a whole series of courses going through pre-algebra through calc. Algebra alone is enough to help with a ton of different projects.
NightKingCole is a genius.

Would you consider building a wind generator out of an old treadmill motor? Seems like it could work well.
You caught that toy shoe like a true dad. Lol
I have never wanted to bend PVC pipe, but now, today, I want to. A lot. This is so simple, elegant, effective.
It looks kind of unreal how wobbly it is :-) I Filled pipes with sand and heated them from the outside befor. Never worked very well. Thanks for sharing that!

That's a really great technique! Def gonna use that next time I need to bend pipe. Much cheaper than trying to find flexible silicone rods that fit in the pipes.
One note though is to wear a mask when pouring the sand. Hot silica dust sounds pretty nasty to breath in.
Would it work to cast the silicone directly in the pipe? Maybe use a high temp silicone? I was thinking for cases where you might want the pipe to be clean inside.
If he wears a mask he won't get to tell people he got pneumonoultramicroscopicsilicovolcanoconiosis.
Having worked in the glass industry for 15 years I can say that inhaling ANY silica dust is pretty nasty. Less than a minute in and "then we pour hot sand" and the flash went off in my head. I love it! Been looking for a way to bend inch+ Diameter in a tight radius.
@@dontaskme9047 damn you!!! I was so fascinated by that word I had to learn how to pronounce it! it took me 2 HOURS!!!!

I'm totally applying this to my future projects, I do it a different way but this is better... THANKS!
Steam would is far easier and faster I use a wallpaper stripper 👍🏼👌🏼🤘🏼
Good luck
For those concerned about the sand dust, I only formed two pipes that day, and I think most of what was seen might have been steam from moisture in the pipe. If I were to go into production (which I have absolutely no intention of doing) I would of course have workers wear masks. Then again, the sand is bought identified as "Play Sand", washed and screened, intended specifically for children's sandboxes, where children pick up and pour the sand routinely. I can't remember anyone, child or adult, ever wearing a dust mask at the beach or in a sandbox.
Ok, but if you find yourself doing DIY, car repair or a house renovation a lot. Take some effort to buy yourself a nice respirator, it's definitely worth it.
Clearly the last sentence holds a bit of an ominous tone now.
Well, in the 1950s, motorists didn’t wear seat belts, either.Most of us survived...
Driving by the beach yesterday, everyone had on masks.
Maybe they were out there bending PVC pipe, I can't be sure.
Nice, Paul..)
I did this today to install irrigation. I have some funky curved sidewalks. It worked perfectly. Trickiest part is not getting burned. Once you get a rhythm going, it’s actually pretty easy.
If you have a form, you can mass produce some cool pvc shapes... in scouts we batched out 40 pairs of snowshoe frames with this method. We used a large propane stove to heat the sand, had one crew pouring, another bending the frame, and then pouring out the sand and drilling holes in the frames for mounts. I still have the pvc framed snowshoes, fun for snow days.
If you want to bend small metal tubes, sand also works wonders. Not in the sense of heating the pipe, but fill a tube with sand, close the ends and when you bend it, it wont king and thus you have a constant radius inside the tube, which you wouldnt have without the sand
With copper pipe you can do that with water too. Greenpowerscience has a great video on that.
one really nice thing with metal tubes is to use salt, usually road salt is dirt cheap and it dissolves in water so it makes it easier to get out than sand when doing more complex bends
I use very fine #360 grit silicone carbide powder when I need to precisely bend thin copper/brass pipe. I used salt before, thought they would be easier to flush with water but the salt melted (and then clogged the works) because I had to constantly torch the copper pipe. SiC powder works even if I accidentally heat the pipe to glowing red. Due to it's fine yet heavy density, compacting (light tapping) is so much easier too.
This is the method that I use. It’s hard to do by yourself, I love the mounting system he has for delivering the sand. I make costumes with PVC, because of the durability and the lightness.
I love how you've built such a trusting relationship with your parrot. Not easy to do, from what I've read and seen.

While the method itself is not new, the scale at which this is used is awesome. It proves that we can take a simple idea and make something really big..in this case a roller coaster. That's mind-blowing!!!

Paul: 🙄

This is brilliant! I've bent pvc conduit using a heat gun for simple bends, but this makes anything possible. I was going to build a hoop house w/ other materials, but now I will used pvc.
Awesome tip! A while back I tried making one of a PVC archery bow using the hot air gun to bend the pvc & had quite a few failed attempts after the pvc pipe heated unevenly and collapsed while bending... this is a WAY better method!
This actually a solves a problem I had with an old project of mine. I had built a simple Lego car that followed a pvc track. The car was geared down to drive about 3 feet per hour. Perfect for really slow time lapse stuff. I never quite figured out how to do more complex paths and I think this would have worked perfectly!
This is the only time in my life where I watch through the entire advertisement cause of the damn bird
Thanks! That is a great tip for bending large sections of PVC. I use sand in PVC, cap the ends and then heat the portions I want to bend... but I really can't wait to try this method! Thanks for sharing this.
In the electrical trade we need to heat and bend PVC pipe and retain the inner diameter for wire. We try and use factory bends but sometimes you need to bend something. We have hot boxes, a long box with a heating element and rollers so you can spin the pipe around for even heat. They get hot enough to burn the PVC after only a few minutes. Old tech used a 6 inch pipe filled with hot oil you drop your pipe in. We would use welding gloves to hand form and cool with wet rags to keep it from flattening. I've used sand to bend PVC before I became an electrician, it keeps the pipe from completely flattening. If you wanted to use his method you could dump the hot sand out once on the jig to use again quickly. Thanks
Seem so simple, yet ingenious.
The sand idea is great for long sections. I always use a heat gun for shorter sections. Great video as always!
Make an array of heat guns and an automated roller.
Why not boiling water?
That is awesome! Never realized it would be that simple. It's amazing what you can do when TIME is used as one of your tools!!!! THANK YOU SO MUCH!
beautiful exactly what I needed to know for a custom snorkel for my truck
This is incredible! You’ve taught me a skill I never knew I needed. Now I definitely need it. Thanks!!
For small bends I've found that press fitting caps on the PVC pipe with one of the caps having a small hole to recieve the tip of an air nozzle and then heating the area to be bent with a hot air gun works well. Once it starts to soften, slowly make your bend. if it starts to buckle or kink, press the tip of air gun to the hole and fill the tube with pressurized air that will push the tube out and get rid of the kink (you'll need to keep your other hand on the other cap to make sure it doesn't fly off or you could glue it and later cut it off). Having a helper makes the process a lot easier.
What a great idea,love it!
Such a great and inventive idea. I tried bending the same pipe with a torch for a greenhouse and it was a total fail. I wish I knew this then. Thanks, good job!
Years ago, I really got into aquaponics, but after we moved, I kinda let things go. Using PVC for the tubing and aerating the return water was pretty key, and being stuck with just 90 degree angles of pipe was annoying. This idea of heating up the pipes with sand has me VERY intrigued whenever I start up the project again.
Damn that quote about math... i might just start paying more attention in class now!
I learned that math doesn't lie. Although people often use it to lie or misconstrue a point of view. Like the IPCC. Or AOC.
A course in applied math helped me see how its used in everyday life
@@kennyclement2823 Like learning code, having a project/task/application in mind first makes learning a lot easier. Because the topic has purpose.
I read hundreds of tutorials for handfuls of coding languages, and nothing ever stuck. It wasnt untill I got a raspberry pi and used python to make an led blink that it all made sense. All the 'hello world' on the internet won't teach you anything unless you have something to use it on.
Its not a cheat code. Its more like reading the manual before putting the bookcase together. If you have all of the parts, and you understand how they all go together, you will get the bookcase you were looking for. But if you just go with what looks right or just grab pieces and slap them together you might not even end up with a table that can hold the book, or worse an unexpected camel.
I blame the way math is taught, but people get too hung up on the numbers when what you really need to understand are the functions and how the parts the functions affect the others. You could be taught math purely from a function standpoint and never even touch numbers. But just about every math class is always sit down, shut up, listen to this lecture, put these five pages of numbers together. Because my numbing work is the only way they know how to teach.... It has been detrimental to generations.
I highly advocate for anyone to learn a few functions and just randomly do some math in your everyday life. while you're on the bus going to school or work and you see a car on a tow truck figure out how much more Force that tow truck would exert ar a given speed because now it has 2000 lb of car on it(F=m*a)(google some off the cuff numbers for weights of vehicles and such). Does it have any impact on your daily life? Not really. But taking that moment to exercise your brain to maybe even learn how a new function works by deciding you want to know how much less you weigh when the moon is overhead per se, you exercise your brain you deepen your understanding of how things are connected. I for one I'm into electronics so I'll be sitting somewhere and a sign will turn on and for giggles I'll figure out how much current are those many bulbs pulling, and by extension what size contactor relay would they need to turn on the whole sign at once, what power factor might not sign induce on the utility lines, etc. All for no other reason then to exercise running numbers through equations.
Learning is easiest when it has purpose. No lecture on the planet can impart knowledge where there's no interest (or purpose). Find a reason to use it make a problem and solve it with math. And I'll bet you'll start getting interested in the bigger equations the deeper concepts, or at the very least gain an appreciation for what you already know.
The hardest thing is to do 😉
(Edit: used speech to text, lots of errors, too lazy to fix them, sorry not sorry.)
Thank you for the info I needed some custom bens in the backyard landscape that couldn't be achieved by factory fittings this bending project worked well
As always, a well done video with great information, thank you for sharing!
This is really clever. This really expands the types of structures you can make with pvc.
Union pipefitter here ! I have many years of experience assembling pipe for venting of condensing furnaces, I am impressed with this video!
I've used vehicle exhaust blowing through the pipe to bend pvc on a couple of occasions.
Pretty cool, thanks for sharing!
This definition of Genius! simple. easy. highly effective. This is genius.
Looks lit from the start; also I can't wait to see your bird.

I used this technique to build the skeleton for a dinosaur halloween costume. Used 15mm pipe and just clamped it around some screws as a jig. It holds the shape really well
The audio (level and pickup) is absolutely perfect-- and your voice has the high-quality (pitch and timbre) of an announcer. That makes your DIY video easy to listen to, with no slurred words, etc. We subscribed.
That is a pretty neat technique he's came up with. Works very well, thanks for sharing.
The advantage of "play sand" over construction sand, is that play sand has most or all of the dust removed before hand.

This would make it a good Archimedes screw for hoisting water out of a ditch with a wind mill
This is the old way to bend pipes, filling up with sand an bendit with a spring tool ... i remember a plumber doing it .
Not pvc. Sand has been used to fill metal pipes, strictly for it to hold its shape and not kink. Same goes for the spring. If the plumber you observed was not heating the sand, it he wasn't doing it with pvc.
@@xenonram Sand is still heated for metal work bending, but it's to get any possible moisture out so there's no steam build up in it. Ends usually end up capped in some manner to keep the sand packed in place and not let it pour out.
Indeed a useful little trick to have in the back pocket. Thanks!!!!!
What a great idea, thanks for sharing!
I'm curious if it get soft enough that some sand gets embedded into the pvc on the inside.
Not at bending temps. If you get to the point where the surface becomes tacky, the pipe is mostly unworkable and will fall apart if moved.
It most definitely would, but it wouldnt affect the the performance of the pipe for the way theyre using it.
No, it doesn't get hot enough. You have to get it pretty hot for it to get plastic enough for the same to embed into it. The pvc has almost a "skin" where the same won't stick even when it's plastic.
If it's sticking it means you have the sand too hot. Avoid breathing any fumes. Polyvinyl chloride will act as a nerve agent if breathing the harmful fumes.
Chilly Jack: If you think you like bending PVC then go for it! I used to overthink these things as well. But I've learned in order to get good results I just have to try things out. Ok, I start with a bit of internet research then do a reasonable experiment (like heating it for 20 minutes at 180 C) and see what you got. If at first you fail, make a reasonable judgement on what you can change and try that next.
Maybe try a PVC frame for a camping pack where the PVC can also act as water storage.
I question the safety of that. PVC pipe is only suitable to transport cold drinking water. Hot water running through releases carcinogens in the pipe, making it hazardous. The hot sand used to bend the pipe would have the same affect, and I imagine possibly remain to taint any cold water later added to that pipe. Not necessarily true but thought and concern all the same.
Thank-you it’s just what I was needing!👍👍👍

Any warning regarding aerated micro particle silica, on par with dry cement dust......
Dry sand is harmful, but not on the same level as dry cement. Cement contains lime, which becomes corrosive when mixed with water (like the water in your lungs).
Everything is dangerous. Do this at own risk. Do health research before hand. . .HAPPY
@@quoththeraven5631 You're likely just going to die driving to the hardware store to grab the parts for this project...
Maybe should put warnings on every faucet in the world "Caution: risk of drowning!"
@@TheCaphits silicates getting into the air can very easily cause a long standing disease in your lungs that will persist your entire life.
Not death.
Wear dust masks whenever you grind or deal with dried sand/concrete mix.
It's an accumulative effect meaning just once gets you closer to miserable your entire life.
That's the best pvc bending trick I've ever seen!
So creative!! what a great idea!! loved it thank guys!!
Great tutorial buddy. You may want to wear a mask because of fumes and dust.
You don't get silicosis from pouring sand into a pipe one time, or even the dozens of times he's done it. There was a tiny dust cloud, 99% of which blew away, and of the remaining 1%, he may have inhaled 10% of that. Stay with me, we're at a total of 0.1% inhaled. Then 90% of that is stopped by your house/sinus/mucous membrane. So the few particles of sand he inhaled isn't going to cause him any problems. You get it from exposure over time. I'm struggling to find out where people are getting this silicosis nonsense. If you are cutting concrete dry, once a week, for a couple hours at a time, over years, you might develop silicosis.
@@xenonram
Don't confuse everyone with facts. The world apparently enjoys being terrified of everything. I'm a remodel carpenter and you should see the look of sheer terror on people's faces when you explain to them that some of the dated products in their home contain asbestos. I literally had a couple get so freaked out over the fact that their existing floor tile in their basement contained asbestos that the wife started crying and was convinced that her children were going to die because they'd lived there for about 5 years. The lawyers have done a damn good job of drumming up a lot of panic around a handful of cancer cases.
Please Note:
PVC when torsionally stressed will flex up to a certain point - then it will explode/shatter.
So don't use it for structural "projects".
Or you will be painfully sorry. :)
I agree. I use it for backyard roller coasters for my smaller grandchildren (under 60 pounds).
Torsional stress is really tension stress at 45 degrees. If you stress it enough to break it, PVC can fail in a brittle manner. But my stresses are low. Fracture toughness is decreased by UV radiation in sunlight, so I paint the tracks. I've done fracture toughness testing on painted and unpainted PVC conduit, after 2 years of sun exposure. If I were to make a BYRC for kids up to 100 pounds, I would use schedule 80 conduit. For riders heavier than that, I would use steel.
Genius! Thanks for sharing.
thank you, greetings and health to you and your loved ones from South Africa
Is no one going to say anything about "This guy totally looks like... Ted Cruz' little brother?"
30 seconds in was way more complicated than is reasonable
That was my reaction. I kept thinking to myself that the bending part is actually the only thing simple about this process. It’s everything on the side to make it plausible that’s makes this beyond most people’s ability.
Came to see Pipe Bending but got a real show with the Star of The Video~!! That small Parrot is really something and I didn't know a person could have such a Clown within a bird~! That bird is something special. Thanks for letting him or her be in the show~!!
Daaaamn that is so fantastic. I love it.
Oh my. Please wear a dust mask when you start doing this on your own. Silica dust is terrible to breathe.
For sure!
"Play Sand" as mentioned and used in the video is far different and safer than silica sand! Please don't unnecessarily spook a lot of people. (And yes, silica dust is very nasty in your lungs and skin.)
Mike Gustafson
It’s not shown which specific brand he uses, so I just picked the most common: Quickcrete. Its safety data sheet specifically warns about the silica in the sand. While I understand that play sand is made to be safe in regular use, this application is not regular. You can clearly see the the dust billowing straight toward him as he pours it into the tube. I’m sure the excessive dust is a result of the baking process.
