Old Yoshimura way. Pipe bending.

[@Wolf_Sim.Actual]

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!!

[@jacqueoff]

Nice explanation. I was wondering what he was doing with that wire.

[@beakerunrefined4230]

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.

[@WelLRoundeDSquarE]

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.

[@nos4me]

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?

[@PhunkBustA]

i was thinkin about this the other day, why not use something like hydraulic fluid?

[@atsernov]

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.

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.

[@bulldogblvd]

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

[@sideshowbob5237]

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.

[@DiffEQ]

Really? He's heating a granular-filled tube and bending it while bringing it to plastic deformation temperature. Same process with plastics... just more heat with metal. That's hard for you to understand?

[@tonycstech]

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.
