I can hardly believe my eyes! The way you demonstrated a single approach to make tubing cope cuts at any angle, with common shop tools is truly astonishing! You are also an EXCELLENT teacher.
Just watched this video again for the first time in a few years, it's awesome to see how far you've come and it's obvious why you were able to do so. Congrats on your success man!
Hey I’ve been watching your series and they are all amazingly informative. Just learning to tig weld And all your information is spot on. Thank you very much.
Your instructional abilities are actually quite good. Just the right amount of explanation and visuals. Not under explained and not OVER explained either - just right. And the flip the tube marks bit so you aren't trying to make cuts to the right of the chop saw blade is helpful (also a mistake I make all the time!)
@@thejagc3736 it's a welding arrow. They are magnetic and used for exactly what he's doing. Gives you 2 free hands so you can tig or whatever else you would need your second hand for
+TargaWheels I have to agree with that one the 1/3rd rule works so well. i have been trying to notch tubing for a while and its hard but that rule works so well!!
Suggest beginners start by buying a length of exhaust tube and use it to make various angle joints. Exhaust tube is cheaper than structural tube but welds the same. Start with the simple jònts and work to the more complex. Do not try to save money by getting cheap equipment. Most cheap welders, saws and grinders wi ll make out far more difficult to learn how to fabricae anything. Do not forget to buy good safety equipment. The arc can blind you, spray can burn a d the fumes are not good for your lungs.
Very cool..... 1/3 the way lap, opposite side marking...check. Now I need a TIG welder. I just got a plasma cutter and don't know how I built the stuff I made without one. Pop bought my Craftsman AC welder for my 12th birthday. It just turned 50 years old and I used it all this week. Great vid...Thanks!
Hi - Just ran across your vid. I'm very impressed! I've been building car stuff and cages since the early '80s and had to figure it out on my own. Your teaching style and descriptive language is spot on and very easy to absorb. Keep up the great work! Have you approached any 'chassis kit' companies about making vids for them?
Great job explaining this process. Unlike so many how-to videos in RU-vid land, you've taken the time to show and also explain the finer details of this job in an easy to understand fashion. Well done!!
Two comments: 1. Skin cancer is not a joke. Please cover skin when welding. Damage is being done even when you do not realize it. 2. Cardboard tubes make great practice pieces. Hey why not #3. Many joints the same? Do one perfectly, then make a paper template for the others.
Fantastic! I do everything else except Welding and Metal Working which thanks to you, I am now on my way to learning and improving fabrication principles! Thanks!
Thanks for this...after watching this my first notch turned out perfectly with a grinder (with a worn out flap disc). Thanks man! I dig your teaching style. Thanks for making it free.
One of the best channels on this topic (and then some). Thanks for sharing your vast, rich knowledge backed up by experience), the info is priceless-- a solid apprenticeship in my view.
Nice. However, it might be more helpful to describe how you are approaching the notches with the grinder as well as the purpose or reason behind that approach in a little more detail. There are a lot of kids out there that watch videos like this and have no one to ask in person. Thanks
I was in a tubing fabricators shop a while back and was impressed by the quality of work and more by the absence of equipment used. I asked if he used software to calculate bends, he replied he had at one time but found his human skills were more efficient and accurate. Skill sets via practice are a great compensator for tools. Nice Video!!
Thanks for the video!. I've watched it a couple times now and tried my hand at it today. Not perfect, but acceptable. I build a lot with square tubing to avoid notching, but it's good to know I can do it with round stock if needed. And no expensive notching tools required. Thanks again, Tim
As a novice welder I'm very thankful for this video and wanna say thanks. Also, I'm driven to ask what's up with the burn patterns on your garage light?
That was a great educational video about notching but good GOD the safety issues. You don't just wear gloves for heat resistance you "big manly man," you also wear them for UV protection. Hope you got good insurance because you definitely got skin cancer.
Not too long ago I made my first TIG welds after studying your videos. Now I just coped my first tube after watching this one. Much appreciated Justin, Thank you!
The workmanship is absolutely fine. But; You use a three-dimensional design program, but you do the cutting with an electric saw. It was very interesting. When I saw the 3D program, I thought you were going to do it in CNC.
Hey Fabricator, you're better than most TV host!!! Maybe one day, you'll be in spike TV. Time for me to refill my inert gas tank and do some welding!!!
You need a die grinder. not some toy as a little Dremel, but a really big one that can use stones, tungsten carbide tips, and emery cloth devices. That will make your life easier.
A fantastic teacher would show you how to do it manually, then tell you to go buy a tube notcher. Why should using the proper tool and doing everything in a single step be worse than eyeballin it with an anglegrinder?
Good tips, keep in mind at 5:50 when using your angle grinder how much of a mess you will have when your loose t-shirt gets into that wheel. Had me nervous just watching.
A poor workman will always blame his tools, or lack of tools. I Iike the fact that Justin, win or lose, just buckles down, learns and pushes for excellence. A professional in every sense.
So to do it without a tube notcher you say just use a tube notcher? BRILLIANT! Just go get a drill press, a clamp or vise capable of holding the tube rigid on the table (a tubing notcher), and a hole saw for every diameter of tube you want to work with? And what if the tube is really long and cannot be held in hand? This method can be done just as accurately for proper welding, and the only tool actually required is an angle grinder with a cutoff wheel and a marking pen. Guess you misunderstood the concept, message, and even the title of this video. You are NOT Elvis. Elvis left buildings, not rooms. You are more like Beavis...Welcome to the world...please drive thru
Tuck your shirt in when using a grinder. I once got my shirt too close and the grinding wheel twisted the shirt, pulling the grinding disk toward my stomach which then sanded my abs. I ended up with a half shirt. I never did that again.
The method i use (as a diy hobby, for very few parts) is CAD model it, unfold the tube with the perfect notch, print it scale 1:1 and wrap the paper model to the actual tube, trace the perfect line needed and cut away with bandsaw/chopsaw/dremel/grinder/file. This way any complicated shape can be fitted to another complicated shape. This way I made a tandem bike from several other bikes. But the bike frame tubing is not round but oval, fluted circles and ovals, triangular shapes, rhomboid shapes etc.. The tubes are thin walled and have large diameter .. so just eyeballing it may get away with good eyes and experience, but this CAD template is 99% accurate if you can grind to a line.
Just came in from my home shop after trying a 45 and 90 using your methods. They worked GREAT and were indeed much easier than what I had been going through. With a little more practice I know I will have a much closer fit-up than on my first two. Thanks !!
You ain't wrong about that friend. I've been fitting and bending pipe and tube for around 30 years and the best I've found is by W. V. Graves. There's the fitters blue book that covers pretty much all you need to know about running pipe, and then the fabricators blue book which has the specific ordinates for laying out any fit or connection you'll need.
Bluebook don't tell you how to lay out a 16 onto a 30 ...1/4 inch from top to top at a 30 dedree angle....I created a device to transfer these marks for a perfect fit ...in about 10 minutes...
Those cylinder cone grinding stones you ca put on grinders work great, and if I have a lot to do like a couple hundred feet of handrail I just whip up a quick jig, even cardboard, or paper to wrap and mark, speeds it up big time.
Подогнал хорошо, но заварил плохо и без газа внутри, тем самым создал себе проблему для сварки. Молодец! Fit well, but brewed badly and without gas inside, thereby creating a problem for welding. Well done!
this video wont play , it says an error occurred , it has done this everytime i try it , 2 days and about 6 tries now . all other youtube videos play fine ?
+ted evans The same thing happens to me on my computer. I haven't figured out why exactly it happens, but I'm still looking for a fix. It's the only video out of mine that doesn't play. I can watch on mobile, or through the RU-vid app and it plays just fine. I hope you get a chance to view it.
+citydriver I will see if I can find a solution for it later and possibly post up a solution. It has received a lot of traffic in the past 24 hours. That might have something to do with it, but I don't know. I'll look into it.
tl;dr Step 1. Pretend to measure. Step 2. Ignore the marks you made. Step 3. Cut and grind stuff. "Eyeballing is precision!" "Imprecision equals reassurance!" NAILED IT!
I made a jig for my drill press a while back, you just stick a hole saw in the chuck and clamp the pipe to the jig and it all works out fine. if I'm doing a weird angle I'll either shim the jig on one side or make the cut and then deepen one side with my angle grinder, depending on what kind of angle I need
Dude, you are good. At first I thought from the title I wouldn't have much to learn, but as the video played and I was busy with the calculator, I looked up and listened to your clear and simple explanation as you did it, and I was hooked. I'll attach the mathematical equation to what you did for those that like to see numbers in action and you have proved it. Thanks for the great entertaining and educational video.
How does he make the first cut at 4:30? I can't see how he's setting up the 45 degree. He does two cuts and has great curvature...but he's cutting two straight lines....right?
I do it all the time ,been doing it for years ,only ended up in hospital the other day (Friday),(after a few lucky escapes over those years?)1mm metal cutting disk attacked my head as I bent down to plug it back in to the extension lead it had slightly pulled out of,I placed the grinder correctly on the bench, plugged it back in, forgetting it it was still switched on.... ,I was bent over, head level with bench(as the lead was on the floor), the grinder flicked 90 degrees and came at my skull hitting me twice, as the first cut bounced a little of my skull,could have lost an eye ,nose or ear,lucky for me my poor wife was home and got me to a near by Hospital,I nearly passed out from loss of blood, lucky no brains to loose, not a lecture, just saying .....these stupid things do happen?
There are instances where having on there makes it awkward or blocks you out in tight spaces but I have two one with and without. I only use the without when I have to.
James T Kirk Akward in tight spaces or not, I have to use the guard at work. If caught without by govt inspector it's a fine for company and possibly me and my boss would tell me to kick rocks. If my supervisor caught me, I'd probably be told to kick rock but no fine.
Very Nice Captain - Just when a 60ish something farmer thinks nothing more is possible,, they stumble in here and get blown away. That therapy moment during shower, pre-stage gathering - worn flap disks - good chance we're skipping lunch today...
Nice! I remember my dad had a book, that his dad had. It basically had a lot of drawings of wavy lines. You went to the chart, and picked the pipe diameter, and angle, then you just traced the line on paper, then took that paper and wrapped it around the pipe, trace again, and cut. I was planning on making some exhaust, thinking that book would come in handy, when youtube made this pop up. This seems a bit easier, so thanks! I also noticed the helmet sticker...Denver? Woot!
67 year old pipefitter welder almost perfect only works with horseshoes and hand grenades. These are some of the simplest cuts to make and there are much better ways of doing it but you must be able to read a rule.
Thanks very much for this video! This method of cutting the fish mouth on the 90 degree joint is great. Assuming the 1/2 and 1/3 diameter numbers, the process can be made even easier by using a little trigonometry It turns out that the angle to cut is the angle whose tangent is 2/3, or about 33.7 degrees. So without having to make any 1/2 or 1/3 diameter marks, you can just make the 2 cuts at about 34 degrees and it is perfect. ( I used a bandsaw.)
You’re explanation of notching tube is great! I was able to notch tube for the first time this weekend by following your video. My second attempt was perfect. Thanks!!
Great video. I've always wondered how this is done. Now I know. Thank you. One question though. How's your hearing? Angle grinder and no hearing protection = deaf as a post when you hit about 60. I've always been very careful with my hearing. I have a friend who wasn't. He's paying the price.
Easiest to understand lesson ever! Umm subbing right up and can’t wait to look through some more of your content! Simple straight forward concepts just getting right to the point in a common sense approach. The way you show this I think my 12yo daughter could do this first try!
8 years ago. Still good information. As you point out, just a tube notcher, hole saw, manual cutting, they all still require more than the basic fishmouth cut. Files, rinding sanding and adjustments to get perfect fitment.
These are the gems that make RU-vid so valuable. Low budget, low production cost, extreme expertise and a great teacher… thank you, brother! I’m going to go notch some tubes!
I know this video is a few years old but wow. I've built dozens of cages, and I must tell ya that your video nails it. It's helped me for my next upcoming cage later this year. Thanks!!
HEY,, REGARDLESS OF WHAT THE X-SPURTS ON THIS CITE SAY,, I thought your video was very insightful and if there happened to be a younger "x-spurt" out here who would like to have some help,, I think you nailed it!
