For anyone talking trash this is literally the son of jesus fucking Christ himself Pops yoshimura. Go fly to Japan and walk your happy ass into the Yoshimura Factory yourself and tell Fugio Yoshimura that his dad had no clue what he was doing… I’d literally stand there and watch while Fugio clamps your arm down in his Vice and radius’s your arm with a blow torch…
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.
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).
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..
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.
Its not about using heat to make the metal malleable and forcing a bend, in fact, its about getting the metal tube to want to bend on its own away from the heat source and with very little added manipulation. Too much heat = burnt metal, too little heat = cracks and kinks (even with sand). Success depends on understanding and applying knowledge in fields of metallurgy, physics, chemistry, and calculus. So yes, this is an art which takes mastery to do properly.
What metal this pipe is made?
No fine sand in side of pipe? Good tecnic. Thank you sensei Yoshimura.
Had 1980 mk2 awesome bike same color too with a kirker exhaust and drag style handle bars
It’s an old clip but……..still outstanding work. 👍🏻
Unless you’ve got limitless access to cheap Russian gas, there’s probably better methods…but I appreciate the skill
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.
Slow,meticulous & made w/pride - what’s not to like ? 👍
What do you fill it with to stop it collapsing do you use sand and cap the ends 👍
Go through a lot gas
My little propane tank would have been out of gas....
He makes it look simple, a man who knows his craft . Dave nz

500 years ago….. he would have been forging a katana beautiful craftsmanship
When you can make something that should be impossible look easy, you've reached mastery of that subject.
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.
Your man is a savage
what he doesn't tell you, the tube is full of sand. look at how the ends are capped. thats what makes this all work.

Man I bet he goes through a lot of gas
Real deal custom race header
That's why we love Japan!

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

It is good idea to fill the pipe with sand. ...but he is doing it great anyway 🙃
the dude is good but that shop man how can you find anything?
Master
Amazing!
что бы не было залома песок например засыпают, в таком, кустарном способе гибки 😀
Is this Mr Miagi's Son!/!
13 minute just watching a man with flame torch try to bending a pipe, why have so many view... I just don't get it
He’s a fish head. Doesn’t need safety glasses.
My garage is starting to look like yours. just hoping I don't catch the filing cabinet on fire and burn down the house
Artist!
Fire and Steel. Heaven
I think this is the best way of playing a metal without stressing it...
Nice work. Headed out to my shop and fabing up a new dual exhaust system using this old school Japanese method.
Totally awesome n sweet
that is good idea if you dont have pipe bender
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.

A Master... My Respect
No thanks , I will stick to hydro forming , and have it perfect everytime.
Yes, he's an artist for sure but damn it gotta be one hell of an a/c bill!! For my always be sweating ass!
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.

What is silver sand and where do you get it?
@@jesselawson1169 Garden centres are the best bet. Put it in the airing cupboard to dry it.
@@sideshowbob5237, thanks I'll look into it
We are out of acetylene
yoshymura has been building headers for yrs. they were famous in the early 70s.
