I use to be a fabricator for rail road, and recently opened my own shop where I fab turbo kits. This video is 100% the best pipe fab instructional learning tool there could be. Great job!!!!

I went to work at a shortline about 5 years back . I have 25 years in hands on all aspects steel fabrication experience They hired me to build their fabrication skills and put together a shop tied to the mechanical department . But had to put me in exsisting department that had an opening. Which was in mechanical.. I took the job becuase of the apeal of the benefits. I designed and built spark arrestor attachment pipes for gp38 locomotives with 2 stroke engines. Which can throw some serious fire up in the air. I think I will just say it was Interesting working for the railroad..fun at times even. I made it 3.5 years found out my mechanical manager was actually trying to pass my skills off as his own. Which has zero of at all in the fabrication world . And was succsesfull enough to get a regional promotion about 6 months after I quit. He is good at stealing knowledge from many people in his career. I can't say I miss railroading

[@zapwatt]

Thank you for saying "locking pliers" instead of using that common brand name. This is proper.

[@TheMrREVOlutionary]

Love watching this kind of work. I do this kind of work for a living so I take quite the appreciation in seeing others methods in figuring this stuff out. I'll be working on an x pipe configuration for my 98 grand Cherokee with a 5.2 V8. I think what's going to be best in my opinion would be a combination of the splayed x portion @ 45* spread and 45* turns to capture the end and make parallel. I tend to like this style of X-pipe for the best flow characteristics as the merge portion is done in a straight section of tube versus a radius. However, packaging is king and sometimes that don't always work. Thanks for the awesome content Justin!

[@tobywhitaker4246]

Very good instructional video! One trick I use for drawing a straight line on pipe, is to lay a length of angle iron on it, such as 1"×1" ×1/8. It works very well. Larger pipe, I'd use larger angle. It self centers.

[@fryloc359]

I've done that too. You don't need to measure either, unless you need to mark both sides.

[@finallyitsed2191]

I have to agree with Deke Bell and his 13 year old son. It's nice to see a video of this quality without all the cussing and backlash you get on other channels. Very nice. I really like your band saw too!

[@chui19801]

Yes, yes, yes. Very professional, extremely good video. God bless your work and everything with it.

[@davidsawyer1599]

Great vid. Like to learn from other trades. I am an Electrician. Months back I was installing a fence. Needed to know a measurement. My college graduate daughter was quite surprised that algebra was needed. The 3 4 5 formula in essence. "Honey everything you use the second step was math after the idea came to mind". Thanks for the education.

[@reneguay1347]

I made mine with a 4 inch grinder and it came out perfect

[@GrindhousePerformance]

Have to thank you for this one Justin, watched this a couple times before tackling the exhaust in my project 280z video series. Those extruded bends were AWESOME to work with.

[@deankay4434]

Austin, another quality video, chuck full of information with little easy math. Great Italian bandsaw with the motor mounted on a gear reduction gear box, plus water-based cutting fluid. I saw what appears to be a 220 volt sticker. I bought a MIG in 1984 build in Italy by the largest manufacturer in their country, still works fine today, but no TIG. Being forced to retire way early, I will own one. I know what’s like to run out of shield gas, why does it always happen on the weekend. Plus, I have seen the cost for 25/75 from $28.52 in 84 to $112.18 just in late 2019 and have every receipt in the file cabinet. Keep up the good work. As a long time subscriber, I guess I will never understand a dislike. ? ASE Master Tech since 78 - Retired

[@themountainraven]

Thank you for the long explanation of things. It takes time and money to present this like you have. Well done.

[@markburton9614]

Great video. A decent, stationary disc sander or belt sander can make up for a less than perfect bandsaw for us home hobbyists.

[@johntenhave1]

That was a masterclass! Thank you. I would love to have seen how you welded that up, and in particular how you got right into the tightest spots. I would also like to know if you would argon back those tubes when welding the complete pipe. great work. I learnt a lot.

[@mattpolitzer2920]

Justin, You're explanations of every step in the process is easy to follow. I look forward to you fabricating a complete stainless exhaust system for my 55' Chevy Truck in the near future. Hope all is well. Matt P.

[@3doghaus]

Great video... Just re-watched it AGAIN!

[@Andrewlang90]

Small tip for the bandsaw for anyone. Slow the feed down, and have just enough pressure so that the slower fed blade has a chance to bite rather then skate or slide across the material. Great video Justin, quality work and content as always 😀

[@TheFabricatorSeries]

Andrew Lang Yes - it's a dead slow process. I should have mentioned these cut shots were sped up to 400-600% and they still look slow haha. Thanks for the tip!

[@Andrewlang90]

[@jwright650]

What TPI (Teeth per Inch) is good for .065 wall tubing?

[@Sicktrickintuner]

jwright650 as high as you can find, i use a 10tpi, but super thin wall i might go to a 16tpi or finer.

[@jwright650]

I'm using a 10tpi and it rips the teeth right off the blade.

[@jimmyray2008]

You have awesome videos man! Very easy to follow... well done!

[@magnus5356]

A much faster and accurate way to get a centerline on tubes is to take two pieces of tubbing of the same diameter, clamp or tack them together at the ends, take a straightedge or similar, lay it over perpendicular to the lenght and drag it along the tubes. Flip them over and do the other side. Boom! Lines on exact center exactly opposite each other!

[@22mikelwho]

Finally a thorough explanation of the differences. Fantastic video!

[@johnrathbun2943]

I'm curious about how you weld in between those pipes when you can't even get the cup in there. I see you tagged them prior to full assembly, but you didn't weld them. I assume you could weld them at anytime, but to get in between those close junctions like on the X's, this is where you will have problems welding because of the cup on the tip

[@ricardosampedrobea294]

Hello @The Fabrication Series! thank you for sharing your knowledge, I would like to know if it is possible to know if I calculate custom sizing for each type of X-pipe motor together with the anti-drone J-pipe and if it is possible to calculate certain frequencies to be able to reach a desired sound as a final result. Thanks a lot.

[@gjrt7573]

This guy is the number one source from getting into welding.

[@baconbam4240]

So if you had a way less of degree of entry (8° vs 45°) and working with baby pipe (1.25”) wouldn’t it be better to cut less of the diameter and extend the length of the cut? (So like .125 “on each pipe diameter cut running 1.79” so the area of the cut is equivalent to the flow of one pipe or should it be two?)

[@mkfourgli1]

New sub, love the content bro. Thanks

[@andrewwilson8317]

Quick tip from me that works- tack weld the pipe to the bit of box section support. Keeps job well supported and easier to get set up right off the saw. Quick clean up with grinder and ready to reuse the supports.

[@terrinewman7390]

Justin, can you use a mig welder toput the tubing together?

[@erikdodson7673]

I’m sure you have answered this before, but what’s you tig set up. Like how hot are you running, how thick is the pipe, and what size tungsten are you using. And what size filler metal is that

[@alanmony1582]

Just a tip from a US standard to metric convert. If you use a metric tape to do all your measurements the math gets much easier Instead of trying to figure out 1/3rd of 2 9/16" you just figure 1/3rd of 90mm. You can do that in your head, ez pz!!! Still a great vid on how it's done. I'll file this one away for future reference.

[@erjack40]

ALWAYS wear a leather glove on the hand that's holding a part for grinding or deburring. The grinder can slide off the part and onto your hand, a deburring bit can break and the nub will cut you like a knife. Hands- on experience from a greybeard.

[@Drunken_Hamster]

From what I understand, you could also make a y pipe by welding two angled pieces together and lobbing off the end. Still have to swage or flare it to make it round, but it should be a little faster fab wise. Probably better for making Y's that have a bigger single pipe than the two individual pipes. Which, by the way, are made for overall flow rate matching. If you have a V8 making 600HP, then you have to either have 1 pipe that can handle all of that flow, or two pipes that can handle half of that flow. 2.5 duals can do it, but a 2.5 Y into 2.5 will likely choke it. This is why you go 2.5 Y into 3.5, as the total tubular area of a single 3.5 is about the same as two 2.5 pipes.

[@TheMrREVOlutionary]

I've actually built a few Y pipes this way. Honestly it's the same whether you use a radius or a straight with some kind of angle cut. How you mentioned does make it a rather simple and time effective way but can limit packaging too. Whatever fits and has relatively good flow characteristics is king! 😎

[@weskirkland5850]

Stuffs so pretty!

[@liamjenkins82]

I was always shown to make a common line on pipe just use a straight piece of angle iron! Was always easier and quicker. Enjoyed the video though. Clear concise instructions. When tacking you use a hotter amperage than if you where actually welding. I don't get to do much tig unfortunately.

[@robertweitlauf4653]

[@youngmango4508]

Do you have a video on making a fishtail exhaust. Searching everywhere.

[@bahalp3241]

Does it make a difference how long the h-pipe is?

[@mrgreenswelding2853]

Thats awesome work Justin!!

[@kenselleck2414]

On an X pipe the elliptical area should be the same as the cross section of the pipe. The outlet pipes can have reduced diameter after the X without flow loss as long as the cross section of the outlet pipes together isn't less than 1.5 times the cross section of one of the inlet pipes. Also on a y pipe the exit should be 1.5 times the cross section of the inlet pipes. If the inlet pipes are the correct diameter merging into the same size pipe will be a restriction. You need a larger outlet because the frequency of the exhaust pulse doubles.

[@tidan1]

How might you go about welding a 3" exhaust to a 2.5" y-pipe collector without restricting any flow?

[@konnerkramer329]

A 3" y pipe

[@carlpenney901]

On the H tube I would drill the holes to the size you need. Then saddle weld the cross tube onto the H tubes.

[@mikegoodman447]

Great stuff! On the "Y" pipe to larger outlet could you say oval the three inch outlet in a press and then cut the intersecting two pipes with a shallower cut to then intersect? Can you do the math on that?
