That is handy when using an angle grinder to cut the pipes for right angle joints like what is done in the video. Of coursse doing so would be esier and faster on a miter saw if one has it.
Not everyone has miter saw smart guy. This video is useful for people with angle grinders and simple tools and for small projects OR when the pipe is too big for the miter saw (didnt think about that, did ya?). The point is to display practical and creative skills thought out of necessity. By your logic "everyone" can just use a pipe guide and mark it up smoothly and cut up everything in one go.
@@jeremiahmccutcheon3234 you're bigger pipes are usually cast iron and concrete line for water can't be welding when you got concrete and just destroys the concrete then you get rust you have to use a mechanical joint even if it wasn't concrete line can weld cast iron but it would destroy if it was a concrete line which all water lines are
@@mikesmithey1892 actually I am speaking on industrial pipes like at any refinery ,pipeline, chemical facility. Most of those pipes are stainless , incomel monel. Exitic metals. Definitely not cast iron.
The subject of this video is not complex or hidden. It addresses how to DESCRIBE a 45 degree angle on pipe / tubing without using 'specialised' / 'conventional' tools. The process / method works regardless of the material from which said pipe / tubing is manufactured and / or the diameter of said pipe / tubing. For whatever reason, the piping / tubing might not actually be cut. A 'cold saw' is designed and intended for cutting METALS - including in pipe / tube form. If the pipe / tubing one intends to cut is made from flexible plastic or rigid PVC, how doe a 'cold saw' help me to DESCRIBE the angle to be cut?! Do you recommend using a 'cold saw' for actually CUTTING flexible plastic and / or rigid PVC pipe / tubing?! Do you know some alternative process / method for DESCRIBING a 45 degree angle on pipe / tubing - without resorting to using 'specialised' / 'connventional' tools? If so, please post a video so that we may ALL be educated.
@@trueaussie9230 what are you talking about? This video is obviously about cutting metal. And yes a mitre saw would make it easier and much much quicker.
I only scrolled down a couple of comments but, the simplest solution is to get a copy of the Pipefitters handbook and wrap a piece of material around the pipe, cut the material that is now the circumference of said pipe. Fold it and unfold it then use the measurements on it, connect the lines, cut it out, and you've got a template for later use.
You could save yourself the work of making the cutout and just use the end of one pipe to mark the other and vice versa. You could also take a hole saw or something of similar radius to roll it around the curvature and mark the cut better. Either way, this method is just an approximation, so it doesn't matter much.
Used for big pipe, never seen it done on anything less than 100mm. Even then the cardboard template isn't used. Just mark down to the same measurement as the diameter.
I understand not everyone has access to a band saw but if you’re going to be fabricating metal you really should have a chop saw at the bare minimum which would completely eliminate the need for all of this
Thanks, neat trick will have to put it into my notes. I had made a fixture for different angles, but this would be easier and faster to set up for a cut now and then!

@@trueaussie9230 a chop saw is cheap and very basic. Anyone that does any type of metal work at all, especially someone that is cutting and welding tube will have one.
@@JohnDoe-ud2cc So, are you saying when someone finds, for the first time in their life, they need to cut metal pipe / tubing a 'chop saw' will just magically appear - regardless of where they're located at the time?! Are you saying that, simply by OWNING a 'chop saw' it will always make itself readily available to you wherever you're located at the time of needing it?! Damn. That's some seriously MAGIC tool. (Have you NEVER found yourself in a situation where a tool that you OWN and need for the situation you unexpectedly find yourself in, is not readily available to you - perhaps because it's in your toolshed and you are 50 miles away from it?!) The technique demonstrated - ie for DESCRIBING a 45 degree angle on pipe / tubing - is applicable regardless of the material from which the pipe / tubing is made. So, for someone who works with PVC pipe / tubing and NEVER works with metal at all, how does that magic 'chop saw' help them?! Will it still magically appear to assist with DESCRIBING the 45 degree angle. (I don't know about you, but I wouldn't recommend CUTTING PVC with a 'chop saw'.)
@@trueaussie9230 man did I touch a nerve, a bit sensitive are we. I can come back and use your same argument back on you. What if a person doesn’t have a cut off wheel or grinder, a welders 90 magnet, a welder, paper, a sharpie, or even electricity for that matter.
Yep , I'd say just get a chop saw if you're going to make a bunch of angle cuts , cutting out a bunch of circles trace them onto the pipe and cut just seems a little too ocd for me . Really I can use a speed square and eyeball angles within reason and make up any imperfections with a mig . And if I needed the perfect cuts , like for no filler rod if I learned TIG (I want to soon) , I'd just go the extra mile and buy a chop saw if I didn't have one .
@@trueaussie9230 I don't mean to dismiss your problem , but if you have a welder and other fab tools , then you should invest in a cheep chop saw . Even a hack saw can make 45's . The main thing is having a decent jig design . And if you are MIG welding or stick you can repair any imperfections from the cut . But if you have a clean place in your fab area to play around with paper and cut outs ? Knock yourself out . I don't know your situation , but when you are a long way from a town you need to work on increasing your tools , unless you're just hobbying , then I guess the circle is a good thing .
@@trueaussie9230 well Einstein, cut it exactly the way he did, just all that layout is not for mating pipe the way he did it, its for butting one pipe into the side of another
@@DD-gi6kx I'm always interested to learn an alternative method. I must conclude that you don't know of any better way that does not involve 'specialised tools / eqipment'. I really can't understand how my comment can logically warrant your passively aggressive and abusive response. What you choose to 'assume' says more about you than about the subject of your assumption. Perhaps you could try pulling back on the aggressive negativity. You might find your life improves. (I note the absence of any semblance of appology)
Nice work, but no need for paper, and all this time, just calculate the width of the pipe and start cutting the pipe to the other edge at angle 45, you'll get the same result.
Easier way. Set your saw at a 45° angle and cut. There you go, now turn one of the pipes so they make a 90° angle and weld. No need to make a bunch of makes. Only one measurement and one mark needed.
Unless you have the proper tools and are only cutting two. This is quite useful and faster if you're cutting plenty of pipes at right angle, since you have a template already. You dont even need the magnet.
To all the critics, and their miter saw. This video is about a skill and "How to". I have been camping and made fire and cooked using an improvised "bow fire starter" Your position would be that I should have brought along a portable stove.
@@Corathor - Not really that much work really and the cut-out can be reused many times. Without any tools (even without the magnet this technique will still work), you'll probably take as long or longer to get a proper angle with other tecnique using a simple right angle, tape measure and a hand saw. Of course if you already have a miter jig then it's no problem, but that's not the point.
@@trueaussie9230 bro you’ve commented to every person that mention any type of tool other than a pencil. Just let it go, let them miss the interpretation.
🇨🇱 Just looking on the title page, isn't it much easier - while the pipes are on the magnet - to just align the saw perpendicular to the diagonal, at the vertex of the pipes/magnet 🤔 ‼️⁉️Saludos de 🇨🇱😃
With the magnet holder it's much easier. But this technique is useful even without the magnet. (I think he just use the magnet holder just to show how accurate the cut, even though it's not needed here)
If you have no fucking clue what you're doing, yeah, this will work. However, this can be done basically freehanded and in about 30 seconds including the cut and to fit any notch.
Can you make it more complicated? I would love to see ;) So simple thing but you found it so difficult. Also if you are going to weld it you need the air gap.
@@TheRealMonnie k... We're talking about simple miters! it is not freaking artistic expression... There is a difference between being creative and being ignorant...
Monnie Holt 😂😂 Do you know the reason we do certain things the same way for centuries? Because it’s the proven to be the best way. Ever heard the phrase, no need to reinvent the wheel? That applies here.
Mitter circular saws work only close to half the diameter of the circular saw but if the width of the object material is bigger than the diameter of the circular saw then it doesn't cur all the way through but this is perfection of another way of cutting a 90 on any pipe size, that is if the craftswo/man has the right saw and or other tools if not.
All these channels that produce videos strictly for views. Always doing overly complicated operations for results that can be achieved with cheap easily obtainable tools. Always a guy with angle grinder and titles like “impossible joint!” Or “the secret pros don’t want you to know!” Yawn
So, you're dependant on having every ''specialised tool' readily available at all times. It never hurts to know how to survive without 'modern technology'. Good luck to you.
@@trueaussie9230 a miter box isn’t “every specialized tool”. It’s very cheap and very common particularly if you make cuts of wood or metal even sporadically. If that is too specialized or doesn’t apply to every situation than you could argue having an electric angle grinder is too technologically advanced.
@@onefortheroad2291 Regardless of cost, I don't always carry a mitre box and / or an angle grinder. Also, I'm not always in easy reach of such things. Do you ever leave the 'safety' of suburbia?!
@@trueaussie9230 but you do always carry a hacksaw? And you do find yourself out in the wilderness in a life and death situation that requires you to make 45 degree cuts in round tube? Your argument is silly and you just respond to every single comment on this video that’s even remotely critical of the video.
Sure, if you 100% of the time have access to a mitre saw. The fishing boats I used to work on had minimal tools, never a mitre saw. I like to learn new ways of doing things I already know how to do. You never know when it might come in handy.
@@vandalsgarage it's called a fucking speed square. If you don't own any tools how are you going to weld anything without a fucking welder? Just fold a piece of paper diagonally and you have a more accurate square than 99% of the Chinese junk they sell at Homeboy Depot.
Nice way to approximate the layout. ALTERNATIVE With those two tubes held in the magnetic square, one straight cut across both ends simultaneously, by disk grinder or portable band saw, will yield a joint mitered to give a perfect 90 degrees. Even if your chop is not at a perfect 45, the error will cancel out on assembly, giving a perfect right angle. No layout, one cut, done.
That's the first thing I thought in the first few seconds of the clip. You would need a clamping jig that holds the two pipes perpendicular. That little red magnetic square won't do it because of two reasons: magnets don't hold as strongly as an actual clamp, and that square extends all the way to the end of the tubes, the clamping jig would have to grab the tubes a little further from the ends just in case the saw comes too close (gotta allow about 1/8 for the kerf). Still though... just get a bloody miter saw already.
Am I missing something here? If you make a 45 degree cut in a round pipe, and rotate 1 side through 180 degrees bringing the 2 cut edges together you form a 90 degree angle just like this. Exactly like this. No template. No marking out. If you want a 60 degree corner you make a 30 degree cut and so on. Just saying.
@@markharmon4963 all the time. I am a fitter/fabricator and 99% of the time I’m in the field working on a job, I have no access to a chop saw or mitre band saw, so everything is done with a grinder. Maybe Alan has never done field work before, so he assumes it’s just as easy as setting up a saw to cut whatever angle he wants. Knowing how to lay out cuts on the material is a very valuable skill.
You can also measure down from your cutting edge the diameter of the pipe. A 45° cut will always be the diameter of the pipe. 2" pipe; measure down 2" on both pipes. 4" pipe same thing.
Good tip! A 45° angle is just the classic rise-over-run equilant of 1unit rise/1 unit run. This comes from geometry and the equation for a line: y = mx +b, where m is the slope of the line and is defined as: (change in y coordinate)/(change in x coordinate), in other words rise/run.
@@trueaussie9230 You could literally accomplish this with a mitre gauge and a hand saw, both of which are not specialized. You can make a mitre gauge in half the time it takes to use this method to mark the pipe. This is overly complex for no reason other than getting views on RU-vid. Probably one of the dumbest methods I’ve ever seen to accomplish a 45 degree cut.
Another good method to have if you don’t have anything else to use you can use a big leaf in place for this. The point he is making here this is a method to get professional joints. No excuse for shit work. Thanks for posting!!!!!
Plenty of nay-sayer jack holes here. Yes know-it-alls, we can use a miter saw. But there's more than one way to skim a cat. Maybe a guy doing a project doesn't have a miter saw, this can be his next best option. Quit hating people for not doing things your way. And this was a very cool video!! I want to try this to, maybe give my saw the afternoon off!!
So, if one needs to join pipes of diameter smaller than 10" and one doesn't have 'specialised tools' readily available, you recommend "don't even try"?!
@@Fordgroup00 Regardless of cost, is a 'chop saw' not designed for the specific and sole purpose of cutting at precise angles?! Can a 'chop saw' be used to lop the top off a 30ft tree?! Is a 'chop saw' not considerably more 'specialised' than what was used in the video - to successfully achieve the same result that a 'chop saw' would produce?! I'm at a loss to understand why soooooo many people -predominantly Yanks - have got their frilly pink knickers in a twist over my use of the word 'specialised'. Maybe you all need to consult a dictionary before going off on a peurile rant. (For your assistance - 'specialised tool', a tool designed and developed to perform one particular task.) Regardless of what tool would perform any task faster than 'basic' (I hope that word doesn't trigger more aggression) tools and regardless of how one describes that tool, if it's not available to you at the time and location you would like to have it, are you just going to sit on your arse and cry?! This video demonstrates a simple, very basic, procedure to resolve a, very simple, problem using VERY basic tools. So, as we say in Aus, pull up your pants and give your mouth a go - ie stop talking out of your arse. Over and out.
That is a very cool method, altho very complicated, i like to just stack the pipes on top of each other at 90 degrees and cut thru both at the same time
@Roger Paul, astute, and the voice of experience. I just wrote something similar. The key to your method is shown in the first scene; the mag square. One chop across both ends at the same time will give a perfect 90, self correcting for small errors in eyeballing the cut at 45 degrees
I cut 35 pieces of 3" pipe at 45-degree angles and saw this was still life hacking a "never told before trick". There is a reason why it was never told....
@@Exotiq. what about if you dont have pencil or pen? Or you dont have paper? Oh wait, what about if you dont have saw 😂 That plastic box is cheaper than your saw, so what an excuse? You have welder there to weld 45 degree iron, bur you dont have mitter saw? At least you have 45 degree guide. This video is nonsense and you defending the nonsenesnes. Welcome to the world 🤣
