Sad that people are missing the point here. He has made a template for a pipe that will be part of a custom header - that's the wire bit he's holding in his hand. This technique s letting him bend multiple custom radii as required to ultimately allow the pipe to contour to the header design. You can see the header set-up on the bench, and the heavy cut dies just beyond and to the left of the vice. The trick is knowing how much heat to apply and over what surface area, always testing the resistance of the material by feel (pipe extension, sleeved), and literally "going with the flow". You can't just pick up a torch and "have at it" - this would take a lot of experience over many years, great skill and, most of all, a great feel for the material. That's VERY hard to teach! This guy is as artist. I would like to see anyone try using a pipe bender to achieve this. How many radii of different bends do you you get with a pipe bender set-up for one size of pipe or tube? ANSWER: just the one. Hats off to this craftsman. Awesome skills!!
having bent 100's of pipes using heat, i can tell you first hand that to bend that thin wall tubing without it collapsing or even getting a little flat is an art all it's own. What a testament to his extreme talent. If that's Titanium tubing, that just makes it so much more impressive. O', not sure but I think he's using Oxygen/Hydrogen in his torch, and not acetylene or propane. I would also add for you "filled with sand" folks, it's still not that easy even if you do full with sand. Be my guest and try this with or without sand. BTW, do it with .030 wall Titanium tubing like he is using. if this shit was as easy as you all claim, and fucking idiot off the street would be doing it. Way more involved here than simply bending the tubing also.
lol you're getting upset about something you've made up in your head. nobody is claiming the sand makes this any easier, they are just pointing out its probable existence. why are you so defensive over nothing?
Because of the heat. The heat required to bend metals without stressing them is more than most (any?) fluids can handle. If cold bending with tools you could use fluids, but then you can't bend by hand.
till youve tried it , you will never appreciate the talent this man has ,,, full of sane , springs etc , its just not easy , this isnt a garden hose hes working with.
Close radius??? That bend radius is clearly more than 1.5 times the diameter of the tubing and is considered a long bend/sweep. It is not a tight or close radius.
I'm not sure if I'm seeing this right but, was he at some places pushing on the pipe (toward the clamp) and leaning at the same time? Sort of finessing the arc to change as needed by leaning AND pushing? Don't know if that's what I saw but one thing is sure... this guy has skill. Very cool.
That shows that the human still the best machine. He has a good understanding of what the metal is doing, what is going to do and where it needs to be and for how long to apply heat for.
People who know what they're doing also wear PPE; The two are not mutually exclusive and cemeteries/hospitals are full of people who "knew what they were doing."
@@DiffEQ They're about as close to being "mutually exclusive" as it can get. We are in a time where every idiot without a clue has the acronym "PPE" rolling off his tongue and has his head so far up the posterior of insurance and 'safety' that he doesn't know where their cheeks end and his shoulders start. In general, when you see a person like this, executing the level of craftsmanship that you most likely haven't the first goddamned clue about, it's a given that they understand the risks involved and behave accordingly. It really isn't so hard to understand, unless a person is of you're ilk and thinks donning every piece of 'safety' attire and dayglow hoopla is going to keep you out of the hospital and cemetery.
He is a skilled craftsman, working at his own comfortable pace. The video shows you can get very good results doing it the old school way. I believe he may be using a mix of oxy/propane for his torch. Much cheaper than acet. Good video.
@@SirCavemaninthewest Why would he use MAPP gas???? LP is readily available and relatively inexpensive. Propane will fule a 3,600 deg. F flame so why would anyone use expensive MAPP gas which tops out just 200 deg. higher???? It's definitely not hydrogen... which is just absurd on its face. UGH. People.
It's very cool that he's making custom headers and it' obvious he done it before. Some in the comments are in awe that he's not kinking the pipe. You can sèe in the end of the video that the ends are both capped, the pipe is full of sand. I'd love to see a finished header.
At variance with some of the comments below and based on having done this many times to make my own racing car exhausts: The gas is almost certainly oxy-propane which is quite hot enough to get steel barely red. The tube will be packed solid - really solid - with silver sand (MAKE SURE IT'S DRY or the steam pressure resulting from water vapour will split the tube). The heating is slow because you have to get the sand hot right through - otherwise the tube will kink. Pros will get annealed tube but it can be done with CDS - you just have to heat it at the bend and also ahead of the bend to anneal it. Much tighter bends than shown in this video are possible but you will have to pause and repack the tube because there is inevitably more stretch than compression in the bending so the volume increases. Usual method of packing sand is to weld a cap on one end of the tube, stand the tube vertically open end up, pour the silver sand in the top and tap the tube wall up and down with a spanner for a good while to settle the sand and get more in, then drive a wooden plug in. Packing the sand in really tight is key and also giving the sand time to get hot right through before bending - i.e. patience.
I wonder how his eyes are. I was always told infra red radiation from oxy burners was damaging to eyes in the long term, that's why we needed oxy glasses.
This is a very simple concept. More heat=more stretch. You dont want to apply heat in one area, you want that stretch to be gradual so you dont end up getting that section so thin that it would break open. He is basically stretching the outer edge of the pipe, while inside edge is just bending. heat makes inside edge to bend easier and allot more heat on the outside, allows outside edge to stretch.
it's NOT filled with sand. If it's closed off it is to prevent oxidation or to help contain heat. otherwise it would create a draft and cool it making it much harder to bring it to, and maintain critical temp.
Man can perform magic and he does so by raising a sail letting the wind do the propulsion. Same principal here heat in the right place and leaning into the advantage with natural leverage. I only ask what his torch gauges are set to, Im only yet a novice welded and used to raw forge grinding and longer time consuming things that may seem relentless but do work if you think what can be used as material all around us. Tools are time savers I try using mans most important one, our mind to freely observe and create from there what I want to make. And tools are costly on the reprise of we get what we pay for as quality rises with cost more, and cheap tools send people to the ER or to a first aid kit fast. We take our licks and come back at it swinging a bigger smarter hammer. Old ways still work so its worth the time, its also worth the time to educate ourselves and learn about tools that render any project to a superior product that works like a charm when its brought into action. Magic is applied knowledge or what my grandfather called ingenuity from thoughtful open mindedness leading us in discovery of trials, fails and finally success for enduring benchmarked crafting in time it becomes refined and experience is our teacher or executioner. lol be safe some things you can only do once and others can only mess up the first and last time. Study close as the old men knew for a reason, and to improve we need to listen to what they say or seek the skilled ones that know how and may teach us how also.
Pops at his best,, but lads..this is how we do it in shed land,, and indeed have been doing it this way for years,, But I have to say..I fill my pipes with sand, so I don't crease or ripple. Pops here is heating and bending bare back.., that means hollow pipe,, also that's stainless he's working with..which means,,, the more you bend the harder it gets,, pure skill..
Don't understand why everyone thinks that if you don't push a button and a digital machine does all the work that it requires some zen mastery and a lifetime of training to achieve. It might not be easy to learn, but almost anyone can do this with a couple of days of serious practice and plenty of pipe and gas. Lots of dead old welders in Oklahoma could do this and Old Yoshimura is not bending titanium.
Awesome !! , I need a system for my old Suzuki's I'm restoring ! My 86' GSX-R750, 80' GS1000S SBK, and a 89" GSX-R1100 Endurance would the build period pipes maybe some with modern cans on them ???
Its In This Guy's D.N.A - Japanese are Masters of Metallurgy. -His Ancestors Probably Were Keepers of The 'Secret Craft' of 'Katana' Building, back a Hundred Years or So! - But I'm a bit of a Fan of 'Pops' Yoshimura - I've Got an '85 GSX-R750 With An 'Old School' Yoshi Pipe on it - Man that Thing 'Howls' - Cheers👍😀
No big deal, really; that's what he does, anyone can do that, the **TORCH** does it for him; still,very nice to see,thanks for posting (seen this a few times already over the years lol).
regarding costs of fabrication? I'd bet he charges his customers enough to make his money. I'd also bet people are lining up to get into his shop... heck just to watch him do it. I dunno. I'm piss poor but I get it... my buddy had a friggin bright yellow corvette and someone asked him why he got it painted that color? he answered because I can afford to!
You can't just pick up a torch and "have at it" - this would take a lot of experience over many years, great skill and, most of all, a great feel for the material. That's VERY hard to teach! GIVE ME A DAY
It's not always about easier ways or cheaper ways to bend pipes. It's the skill of hand made/formed components that machines don't provide. I'd rather have a hand made exhaust than a of the shelf machine made product. It's a shame more people are willing to learn how to make things rather than buying rubbish off eBay.
mint it looks like another bulshit yt vid wen ye see him stik-it in the vice and grab a fork leg but that! is a master at work! true metalurgy master.a pleasure to observe
hotsweetness99 can't and can is as simple as leaving out the t when typing lol, you can do what ever you want to if you wanna do it bad enough. You just have to try, its not like he woke up and just started doing this stuff he learned it over many years and no doubt many failures too like all of us mechanics and fabricators 20 yrs ago i didnt know how to take apart and rebuild a motor at all but now I can do it pretty much with my eyes closed cause I've done it so many times
OneBad88S10 no no what I mean is for kids growing up, the distraction of technology along with what we are forced to do in school does not help at all. in my high school the shop classes all got shut down and locked up. students could no longer learn hands on skills, parents wanted kids to become engineers with no practice hands on experience. auto class? shut down. wood shop? shut down. machine operation? shut down. computer programing class? full full full! what the heck do you expect kids to do when they don't even have the opportunity? not to mention the social stigma of manual labor. where I grew up, people who did manual labor (like me, a self taught mechanic) are looked at as stupid idiots. people in school always asked me "why would you want to fix something, when you can just buy another one?"
@@jesselawson1169 yes, but I am a rarity. Nobody else thought like I did. They all wanted office jobs. Maybe it was just my location? I will have hope.
