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.
These are the gems that make TH-cam so valuable. Low budget, low production cost, extreme expertise and a great teacher… thank you, brother! I’m going to go notch some tubes!
Great job explaining this process. Unlike so many how-to videos in TH-cam 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!!
Dude, you’re the master. I’ve spent hours watching your roll cage videos. However, this crap didn’t work for me at all. I built half a roll cage this way. Took three months. Partly because my new MiG kept messing up. I bought a $100 tubing notcher from AMAZON and got out my old Forney flux core and finished it off in a weekend. Again, you are amazing and I’ve learned a lot. I’m glad you’re here. Building a roll cage is a lot different than arc welding on farm equipment. Thanks for your guidance.
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!!
99% of the time these old school methods work so much better then a tool specifically made for the job. Years ago you didn't have a tool for everything, you relied on the Craftsman's skills. This is a wonderful example of skills. Nice job.
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!
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!
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.
+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!!
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 !!
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
2 things, 1 this just made my life so much easier!!! Im bulding a 74 monte carlo into a 1/4 mile asphalt oval car, and i have been struggling like no other to get my notches right with limited tools. And 2 if that kbpi sticker on your helmet means your from colorado, good on ya! I was boorn and raised there. Living in wisconsin now. Very cool to see stuff from people back home!! Keep up the good work!!
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
HI, JUST FOUND YOUR CHANNEL! THANKS, BEEN IN THE BUSINESS FOR 40+ YEARS, AND I GOT LUCKY 20 YEARS AGO, BOUGHT A USED SCOTCHMAN 66 TON IRONWORKER, WITH ALL!!!!!!!!! THE ATTACHMENTS, AND LUCKY ON THE BOTTOM OF THE MASSIVE OLD BOX WAS THE TUBING NOTCHER, WITH 3 SIZES, (SORRY FOR THE CAPS, JUST HAD ROTATOR CUFF SURGERY!) BEFORE, A OLD TIMER TAUGHT ME WHAT YOUR DOING, BUT WE USED A BAND SAW! FINALLY BOUGHT A BIG ELLIS SAW, WOW! AMAZING THE PRESION ON 18 INCH PIPE ANGLES! , LOVE AND SUBBED, GOT LOTS TO WATCH, TO CATCH UP, THANKS AGAIN, JACK, PS AND WHO SAID MATH WASNT IMPORTANT, ESPECIALLY WHEN DOING CONES WHERE YOUR SWING ARC WAS 45 FEET AWAY! GREAT WORK, LOVE TO SEE PEOPLE STILL USING THE HELI-ARC! OPPS TIG.
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.
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?
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!
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.
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!
You said it all when you mention time and experience. I use the machinery handbook a lot and it taught me to do flat pattern layout. Once I learned this, which is same as CAD only manual drafting, making wrap around templates is easy. Then I learned to use the 4 inch disc grinder to cope out the material with super accurate results. I built complete chrome molly tube race cars many times with this method. Your method here is another great way to get the job done, good vid!
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.
Really cool you did this vid. At the shop we too have a tubing notcher, plasma cutter, TIG welder, MIG welder, etc etc etc. The go too tools we use 90% of the time. Cut Off Wheel, Hard Stone, Flapper Disc, on a 4.5" grinder and chop saw. Simple stuff anyone can buy for little investment. Just because you have the tools, doesn't mean you have to use them. LoL, and as for TIG welding. I only do it when I have to do it. If you are using (cheaper) mild steel to learn this, MIG it. Flux it. Stick it. it's all the same and cheaper while your learning it. Great vid as always man.
I don't do metalwork, I'm a woodworker, but I enjoyed watching this. your a natural teacher and made this all seem so easy....(which I'm sure it isn't until you've done it a couple of dozen times) Thanks for uploading and sharing your expertise!
I feel I can (almost) hit the ground running... Once I go through the research to get the most versatile welder, actually get that welder, practice a million times, then refer back to this video for the umpteenth time, to compare whatever it is that I wind up doing, with real deal welding & notching, repeat, repeat, repeat... This is pure gold!
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.
A teacher is never a giver of truth they are a pointer to the truth each student must find for them selves… perfect video. No bs no bad talking products or promotion of anything just a guide to how to do something and practice take your time and you’ll get it. I’ve used high end tools in the past but always seem to go back to this method it’s just faster with practice.
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?
you are extremely good at this method ....i use a milling machine for such endeavors for many years and i don't think i could do this so well first shot .......true craftsman.............BRAVO
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!!
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
As a man who has built 4 awesome rat rods from the ground-up, I TRULY appreciate your work, but it really is easier to sculpture out the radius of the tube with a good ole' bench grinder. You can start with a normal wheel and it will form a nice radius on it as you grind out the first cut. And it IS safer to do it that way because you can use the rest on the grinder to steady the tube. Killer work!!
Thank you. I'll just add that "easier" is a point of view based on the person doing the work. Whatever works for that person is the method they should use. I find it easier to shape with a flap disc.
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
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!
Thanks welder dude! I was a welder/fabricator for almost 20 years. But that’s been darn near 25 years ago. Unfortunately for me I’ve forgotten more than I realized, sooo… thanks for the video I was like a excited school kid watching this. I actually went and bought a wire feed welder I have a ton to relearn.
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
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?
I like that you do it with a chop saw. Just making it easy with tools most of us can afford and throwing in some just plane common sense figuring. Nice teaching. I need a brush up like this once in a while
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!
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!!
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.
I watched this video over and over again! Very clear explanation without the bullshit! My first notch was a bit off, but after my second and 3rd notch I realy had the technique down. THANK YOU!!!
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!!!
Hey buddy, you're pretty good with the pipe and tubing. I built the airplane with all those "clusters" and fishmouthing the tubing all by hand. 2 grinders , one with a cutting wheel and the other with a hard grinding wheel. I used 2 grinders because I didn't want to dink around with changing wheels all time. It saves a lot of time believe me. Your approach is more scientific than mine so I'm going to try your method because I like it. Not that one is right or wrong, just because I like your way. Thanks for your help with tubing issues. You are definitely on your game.
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.)
30 yrs ago I began writing algorithms on a small pocket computer no bigger than a calculator. It was a hobby that went on for years and eventually I got to the stage where it could calculate the ordinates needed for any template to cut any pipes at any angle and at any fitment that could possibly be dreamed up. Then it went onto calculating any type of offset possible with any sizes and fitting up to any other.... The story behind all this is that I used to be a welder and I just got sick of welding 'gaps' all day long and so I just said that there must be a way of calculating things to never ever have a gap ever again..... And I've never had one the rest of my life... But all of that aside, what you've shown on this video is far better than I could have ever done myself freehand... and if the objective is to get the job done, then that's all that matters. I always used to get a buzz by saying to anyone to simply toss two pipes anywhere at different levels and different angles and just with a tape measure and my calculations, I could cut the parts and pieces needed to connect them up with barely any daylight in the gaps.... I hate welding gaps.
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 TH-cam 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.
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?
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...
I realy enjoy your technic. Like my grandfather always did say: " The better way is the simple way! Not the easy, but the simple." Without magics, inventions or bullshits! Tanks and congratulations! You are a great pratice teacher!
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...
No clue why this popped into my feeds now, but 3 months ago I could have certainly used the information. Man, wish I'd have thought of using the hot saw, dang. I love the way you explain the how and why, definitely a great tutorial! That you Sir for the clear and concise delivery of such useful concepts and excellent content! Happy Holidays Mr Fabricator!
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.
GREAT TIPS! Thank you so much! I m not building roll cages but arena drags for horse owners. I have tons of fence post tubing I want to cut and weld. NOW I know how to do it without a tubing cutter! I have bookmarked this link for later reference.
I Learned this technique in the shipyard shop many years ago. The old guys that taught me said that getting a perfectly tight fit creates a feathered edge that just ends up being melted away when you weld. A blunt beveled edge was much more supportive to the weld.
This man wants a world the better place is like he want us to learn, he encourages you, that’s great, you are a leader my friend, thank you so much, God bless
Very nice. You just explained a few things that are really simpler that most people make it. I work with wood and see people over do all the time,,,like me and metal,,,lol. This was a big help. I just subscribed and am looking forward to watching more of your "teaching". Thanks again, Brad
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.
Gunna just cut a hole in my tube to slot and weld the joining tube now I realise how complicated this way is. Thanks for the video to understand though, love your deliberate tones.
He is a professional without the professional tools. That's what a teacher needs to be.
Thanks

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!!
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
+歩春日 That sounds like a useful method.

You have the gift my friend, to think it out as well to share and explain👍
I did this as well but the hole saws sure are slower and cost more to use than abrasive chop saw blades and old flappers.
Seems like you would through a lot of blades.
I see allot of bicycle and motorcycle frame builders notch rubbing like that.
As a man who has built 4 awesome rat rods from the ground-up, I TRULY appreciate your work, but it really is easier to sculpture out the radius of the tube with a good ole' bench grinder. You can start with a normal wheel and it will form a nice radius on it as you grind out the first cut. And it IS safer to do it that way because you can use the rest on the grinder to steady the tube.
Killer work!!
Thank you. I'll just add that "easier" is a point of view based on the person doing the work. Whatever works for that person is the method they should use. I find it easier to shape with a flap disc.
Really excellent video thanks so much for showing this, it was always a mystery to me how this was done so accurately.
And to think, I wasn't giving myself enough credit for doing this for years. Good instructions. Usually harder to teach than just do .
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
9 years later and still helping folks with this video!!!!
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!
It’s called the pipefitter’s handbook
@@johnfeepassword6390 oh, very cool man, I'll have to go look that up. Thank you!
Thanks welder dude! I was a welder/fabricator for almost 20 years. But that’s been darn near 25 years ago. Unfortunately for me I’ve forgotten more than I realized, sooo… thanks for the video I was like a excited school kid watching this. I actually went and bought a wire feed welder I have a ton to relearn.
Drill press hole saw done quickly and no grinding thank you everyone
Elvis has left the room
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
I've just done my first ever tube notching to add a harness bar to a roll cage without a notcher thanks to this video!
I glad to see I'm not the only only one who uses a grinder without a guard........great flick by the way.........Cheers
Thanks for watching!
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?
yep and i slit my wrist open with one without out a gaurd, oh the white flesh looked good just before the blood flow
You mean that funny shaped paperweight they give ya with the grinder?
MrMan put the guard on and it makes it a one way grinder. Not good for any job.
I like that you do it with a chop saw. Just making it easy with tools most of us can afford and throwing in some just plane common sense figuring. Nice teaching. I need a brush up like this once in a while
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!
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!!
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.
What a Nancy. Had me nervous. You don't belong in a fab shop.
@@Anthony_Robert_Stewart job won't get done if you're in the ER
@@Anthony_Robert_Stewart like that grinder no need for it.
I watched this video over and over again! Very clear explanation without the bullshit! My first notch was a bit off, but after my second and 3rd notch I realy had the technique down. THANK YOU!!!
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!!!
+Michael Strong This is such an awesome comment. Thank you! I'd love to have a show on TV teaching all of this. Happy welding!
+The Fabricator
what material are you using
+wael Auto.Eng.student This was 1.5" DOM
The Fabricator
thanks
good lesson I took in that few mins
Hi Michael can you please send me any fabrication book that can help me as a beginner?My email:Abesandavid@gmail com
Hey buddy, you're pretty good with the pipe and tubing. I built the airplane with all those "clusters" and fishmouthing the tubing all by hand. 2 grinders , one with a cutting wheel and the other with a hard grinding wheel. I used 2 grinders because I didn't want to dink around with changing wheels all time. It saves a lot of time believe me. Your approach is more scientific than mine so I'm going to try your method because I like it. Not that one is right or wrong, just because I like your way. Thanks for your help with tubing issues. You are definitely on your game.
Saw the bpi sticker are you in Colorado
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.)
Damn, I should have watched this video a couple of weeks ago! Great approach - simple but effective! Thanks.
Thanks for taking the time for making this. Love watching competent trades people at work
This is great, with these skills you could easily build yourself a tube notcher ;)
Simple, to the point, very well explained and NO crappy overlay music....
EXCELLENT vid!!!! Thanks!!!
EXCELLENT tutorial.. Thank you
30 yrs ago I began writing algorithms on a small pocket computer no bigger than a calculator. It was a hobby that went on for years and eventually I got to the stage where it could calculate the ordinates needed for any template to cut any pipes at any angle and at any fitment that could possibly be dreamed up. Then it went onto calculating any type of offset possible with any sizes and fitting up to any other.... The story behind all this is that I used to be a welder and I just got sick of welding 'gaps' all day long and so I just said that there must be a way of calculating things to never ever have a gap ever again..... And I've never had one the rest of my life... But all of that aside, what you've shown on this video is far better than I could have ever done myself freehand... and if the objective is to get the job done, then that's all that matters.
I always used to get a buzz by saying to anyone to simply toss two pipes anywhere at different levels and different angles and just with a tape measure and my calculations, I could cut the parts and pieces needed to connect them up with barely any daylight in the gaps.... I hate welding gaps.
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 TH-cam app and it plays just fine. I hope you get a chance to view it.
+The Fabricator friend of mine can also play it on cellphone but it wont play on pc ive had 3 friends try it also
+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.
id love to see your method i was trying to notch tube yesterday for making a chassi brace for a g body it dident come out to great
+The Fabricator beware of the view bots are out there as well. also thumbs up 4 wearing them safety glasses.
You’re what every instructor needs to be.
Yes Sir. Great explanation. As we say in Québec. One Tird
Is that like having a single piece of poop? One tird?
Can't count to four because the trees get in the way....
ayyyy
I have no reason to learn this information but I do not regret watching. Great instructional video!
Sick video man, I love the KBPI sticker!😀
Was just going to comment the same thing, noticed the OLD BPI logo on there... Rock on and thanks for the video, super helpful!!!
You welding skills and instructional skills and video production skills are all very impressive. Thanks for sharing with the rest of us.
Great Video! Liked & Subbed. You're a fantastic teacher! Looking forward to catching all your Videos! Have A Super Week!..... Gus
Thanks for the sub!
I agree. You instructional technique is awesome, you express you ideas and methods in a manner that is easy to understand, grasp, and replicate.
Well said, great.
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?
You are good. I have been a welder most of my life. Saddled up to 12" pipe, but with a cutting torch. Never worked on a roll cage.
just buy the pipe fitters blue book and you can do anything
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...
I realy enjoy your technic. Like my grandfather always did say: " The better way is the simple way! Not the easy, but the simple."
Without magics, inventions or bullshits!
Tanks and congratulations! You are a great pratice teacher!
Good advice. I usually just say that the best way is the way you work best with. Thanks for watching!
The Fabrication Series Tanks for answering!!!!
KBPI has gone down hill in the past few years
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...
"Throat depth."
The inner 14-year-old me: "Hahahahahahahahaha!"
"Mating tube"
inner 14-year-old me: ( ͡° ͜ ʖ ͡°)
My inner 14 year old is more like “tehehehehehe”
No clue why this popped into my feeds now, but 3 months ago I could have certainly used the information.
Man, wish I'd have thought of using the hot saw, dang.
I love the way you explain the how and why, definitely a great tutorial!
That you Sir for the clear and concise delivery of such useful concepts and excellent content!
Happy Holidays Mr Fabricator!
Learn pattern development
I have for sheetmetal mechabnic I guess roll cage does nt have to be as acurate
Certainly one of the best instructional videos on line.
guy kinda sounds like Cory Taylor.. I feel like I am getting a lesson from Slipknot!
No he doesn't, lol.
Its nice to see a person who can think OUT SIDE THE BOX.You go dude, job well done.
Lol... does ANYONE use grinder guards? They need to stop making them so we can save on purchase!!
Yea, what he said.
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.
@@AndersHanche been there, done that and still don't use one
Grinder guard really isn't needed for flap disc use. It just gets in the way when digging out deep angles or odd surfaces
Always been my nemesis, should have watched this 50 yrs ago, impressive many thanks.
Excellent, I just used this technique and got a great fit up for a close tolerance tube BETWEEN two fixed tubes.
GREAT TIPS! Thank you so much! I m not building roll cages but arena drags for horse owners. I have tons of fence post tubing I want to cut and weld. NOW I know how to do it without a tubing cutter! I have bookmarked this link for later reference.
I Learned this technique in the shipyard shop many years ago. The old guys that taught me said that getting a perfectly tight fit creates a feathered edge that just ends up being melted away when you weld. A blunt beveled edge was much more supportive to the weld.
as a union millwright and owner of a fabrication and machine shop,hats off! great video
Thanks for watching!
This man wants a world the better place is like he want us to learn, he encourages you, that’s great, you are a leader my friend, thank you so much, God bless
Been fabricating for 6 years, haven't done much tuning but this is a great tip
Very nice. You just explained a few things that are really simpler that most people make it. I work with wood and see people over do all the time,,,like me and metal,,,lol.
This was a big help. I just subscribed and am looking forward to watching more of your "teaching".
Thanks again,
Brad
I love this kind of fabricación without fancy tools. This could save a lot of time.
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.
Gunna just cut a hole in my tube to slot and weld the joining tube now I realise how complicated this way is. Thanks for the video to understand though, love your deliberate tones.
Use whatever works best for you. This method is actually very quick and can be faster than machines once you get it down. Thanks for watching!
This is a fun video to watch whether you are interested in metal fabrication or not! You are a good teacher and your skills are awesome. Thanks.
Awesome! Thanks for watching!
Really like the channel unlike a lot of channels i actually learned something here thanks.
