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!!

When you can make something that should be impossible look easy, you've reached mastery of that subject.

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.

The old school craftsmen are the best.

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.

I think it can be fairly assumed that this gentleman knows what he is doing, and may have possibly done it before... Beautiful work...

I believe that's Fugio Yoshimura bending the tubing. I was a sales agent in 1973 thru 1983 for Yoshimura Racing Products. I still got my first Invoice of 4 into 1 mandrel bent headers for my Z. I ordered two and some R&T Cams from California and they were back ordered to Japan because of Nixons trade embargo against Japan. I still got all my Yosh stuff and then some.

How can anyone give "thumbs down" to this video. He's skilled as!

I think this is the best way of playing a metal without stressing it...

The craftsmanship here is something that's going to be lost in the near future. Amazing work.

When you love your job so much , you can't quit smiling.

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.

Close radius compound angle bend.....thank you teacher, for the demonstration. .👏👏👏👏👏👏

beautiful. hard to see how anyone can miss the point unless they have no idea what they're looking at.

This guy is brilliant no gloves no safety glasses no worries, just knows what he is doing well done :) !!!

No fine sand in side of pipe? Good tecnic. Thank you sensei Yoshimura.

True master This is awesome Love to see old school tricks of the trade alive Adjusting on the fly

as a weld/fab guy- damn it's impressive what control some people have with heat.. I can only hope to one day understand it that well

yoshymura has been building headers for yrs. they were famous in the early 70s.

Very cool. I hope he doesn’t forget to put his dust mask back on when he leaves the fab shop.

So time consuming so perfect, I love Japanese craftsman of all sorts.

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.

Fine craftsmanship, a flawless bend regarding steel pipe. the vice setup I like as well.

This is like a magic trick to anyone who knows about pipe bending .

J'adore ces techniques à l'ancienne, sans fioriture d'électronique, juste le talent de l'artisan et de son savoir faire.

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.

great vid

thanks! now I want a torch/flamethrower too. :) Nicely done!

True Craftsmanship at work...

Meus Deus, o que é isso? Fiquei de boca aberta, a gente sempre compra ferramentas caras e vê alguém fazer com a mão kkkkkk. Parabéns, gostei.

Wow. That is fairdinkum brilliant mate.Thank you for sharing.

Hypnotic, a true craftsman.

Never seen that done before. Amazing how he gets it to bend without distorting the pipe.

It’s an old clip but……..still outstanding work. 👍🏻

great work

Zen- Bending The fire Must be like Your own Hand

Master of his craft

prime example of true skill and workmanship, kids need to learn this shit nowadays!

A whole lot of expensive tools or a whole lot of expensive skills. Choose one!

All-in-all it is definitely a nice job...!

Top quality work right there

He makes it look simple, a man who knows his craft . Dave nz

Just awesomeness!

That is a master at work. Amazing not even I can get a pipe to be bend in a perfect pattern with out a deformed bend on my end.

I have a 1977 Z1000A1, I dream of new Yoshimura pipes, just beautiful craftsmanship.

Just awsome !

Amazing!

Handbuilt to PERFECTION...

Excellent!

Masterpiece.

No mandrel, torch and pressure to make a manifold. That's nice. Former gixer rider Yoshi was life.

Well I'm impressed.. I didn't realise one could do it like this and not mess up the pipe.

I've watched this a couple of times and I can see what he is doing but I still have no idea how it works - respect !

the master make masterpiece , nice vid

A Master... My Respect

fantastic, craftsman at work.

Amazing, what a talent.

Beautiful... but that will be a damn dull Samurai sword!!!

dudes got skills!!!

this guy knows exactly where to heat and how much to heat. Expert job...but I'd hate to think how much gas he chewed through!!

A true craftsman at work. So many things going on most of us wouldn't start too understand.

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.

Unreal and smooth as a baby's ass! Consummate skill and control. This demonstrates why the Japanese have "Living National Treasures".

that's what you call finesse!!

A master of his art

Artist!

What do you fill it with to stop it collapsing do you use sand and cap the ends 👍

Good skill! Who needs fancy digital pipe bender?

That is amazing a real art and now I read in the comments it's titanium this guy should be working for Boeing.

the man is a genius

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.

YOSHIMURA EL MEJOR TUNEO DE CHILE.

Could you bend stainless steel this way? What does he put inside the pipe?

A lot more skill there than meets the eye..........and is shop looks as neat as mine.......

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👍😀

Marie Kondo says everything there must bring joy.

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.

Totally awesome n sweet

this guy is awesome but is he the yosimira?

Nice clean organized shop, sure hope he doesn't drop that torch, they'll be running for their lives!

Arrrr yes the old samurai way of bending pipes....

This looks like one of my high school shop tests. You had to find and circle all the safety hazards in a picture of a messy shop lol.

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 ???

I like his style. no gloves, no safety glasses, no ear plugs, no boots, sets hot torch down on cardboard box.... no osha lol

素晴らしいスキル Subarashī sukiru

Are you talking about "Pops Yoshimura", the old motorcycle Guru?

That one guy is a superhero

Fucking fire hazard, that whole workshop.

Very nice work friends.

That's why we love Japan!

Fantastic, non servono parole

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..

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

I I used to live around the family in Simi valley CA

Stainless steel ?????

Look closely you'll see the tube is closed off on each end, the tube is full of sand to keep it round during the forming process.

Handsome Flame😆

the dude is good but that shop man how can you find anything?

Hand bent titanium. Beautiful works of art
