Before you comment about your Tig/Mig welder, Please read...
Yes, it is a strong joint, In the UK allot of high end motorsport tubular chassis are built in this manner, very proven technique over the generations from Norton, Rickman motorcycles, Caterham Cars to modern day Ariel Atoms/Nomads and Racing Bike chassis, Superkart shifter chassis, Go karts ect.. And not to Mention Push bike manufacturers around the world.
This exact Motorcycle frame has been racing for 3 seasons now, Taking Pole positions and setting Lap records in its class (without any failures) Proving itself in the Runnings against all the big manufacturers Moto 2 machines. This motorcycle chassis has been Designed for bronze brazed joining from its initial stages as a racing motorcycle.

Are you holding your breath during welds?
@@M4DBMX haha, yes, I use a technique adopted by snipers 😂
@@stubbycuts I do the same, but is just a bad habit for me I guess.
now what I would really love to lear is how to get a good geometry for a sport tpuring neo cafe bike
any advice ? any videos you have made about it? I would highly appreciate your help best regards
I am a 58 year old welder skills like this are on there way out . And yes welding is an art form. You constantly strive for perfection. Brazing is one of the many skills that is hard to perfect. This man has done that . RESPECT
I worked in oil and gas using oxy acetylene brazing for years. This video was great to see.
The bible declares in the last days he will take away the craftsmen of this world
Thanks John, very kind words. Cheers 👍🏼
@@NOBOX7 where the fuck does the Bible say that?

When I left school one of my first jobs was bronze welding motorcycle frames, clip on's, rear sets and headlight brackets for a company called John Tickle racing equipment. I used to do it on piece work rates and earned good money. The job satisfaction at the end of each day was great. (Year was 1969)
THIS IS THE CLEANEST BRAZING I EVER SEEN IN 40 YEARS AS A WELDER...CONGRATS!
I don't think I want to ride on that motorcycle. The braise all those joints it's can't be as strong as regular welding can it? I'm not a welder I am a machinist who was a cop so I don't have as much experience in the shop especially with welding I'm an idiot when it comes to that. This wouldn't be a strong as regular welds would it?
@@brt-jn7kg well, I will love to see what people with more experience have to tell. I have the same thoughts but than I see bikes and motor bikes done like that, and they must be resistant!
@@brt-jn7kg In general they are, the key here is having to deal with less distortion. You also don't get to worry about corrosion. You have to realize the materials are not molten here but the filler is. Either way a good weld or braze is often stronger than the base material. When it comes to precision fit it makes sense to braze. The type of filler is important depending on the application. The cool thing is you can braze dissimilar metals as long as they are "brazable" for example you could have a solid carbide part brazed onto that frame, you could have a stainless steel portion and not have to worry about contaminating it (where it would eventually rust if welded to common steel, specially without ss wire/rod). And probably a bunch of other pros and cons I can't recall right now!
@@brt-jn7kg there is a good reason to use bronze....which is malleability
@@brt-jn7kg the early lotus race cars and such were all brazed together
Amazing craftmanship sir! Beautiful joints!
That’s outstanding. A real art form that’s functional. 👏
Would love to see more videos
What an absolute work of art. A an engineer myself, I am in total awe of this sort of craftmanship. I just hope these skills are never lost.
Poetry in motion. Beautiful to watch mate 🇦🇺👍👍
I'd happily have that frame as a piece of art in my living room. Absolutely superb.
Cheers Andy, my old man’s done just that!
What a stunning piece of artwork! Even if the bike was never to be raced around a track and just kept as a piece of static art it would still be breathtaking, no wonder you need to remind yourself to breathe!
Have been looking for this detail for bicycle building, thankyou
Beautiful Work! I Love the way you "walk" around the joint.
Wow,just amazing work. Steady hands. I love an artisan doing his thing.
Great job, definitely an art! Like gas welding Aluminum, takes a lot of patience to learn and a distinct touch to get it right.
Damn, that’s amazing!! I’m now inspired to try this. The rate of travel is higher than I thought it would be (the pool solidifies quicker than I imagined).
Obviously prep is key like with tig too, your fitup is super crisp.
That is the most beautifully done brazing I have ever seen or probably ever will see. Nice!
You Sir Are a pure Artisan, I learned to do this more years ago than I care to remember now, So very well done and both thumbs up to you
Brilliant mister 👏👍
Was taught this method as a proper apprentice(5yrs)many moons ago.... Funny because gas welding and brazing are still my favourite
Absolutely gorgeous! That frame is a work of art and you sir are an artist.
Thank you sir, appreciate your kind words! Cheers
This guy is so skilled,he’s controlling precise heating on 3 components at once ,utilizing perfect timing,coordination,the results look very similar to tig welding aluminum,bravo!
Wow!! You sir are a master, -thanks for sharing! I love your heat control technique.
Truly a work of art. Fascinating.
When I went to school for welding 20 years ago we did this. I hated it so much at the time for my test I just jammed the rod in the joint handed it in and took the 0. Now how ever this is one of my favorite processes. You are an artist and your work is amazing. good on you sir!
At last, someone who is showing us how to do it properly!
One of the Positives of UA-cam.
Not that there are many, LOL.
I can't say anything that hasn't been said. Amazing, beautiful, work of art,
What a great skill sir.
Thank you.
Stellar job! Man that's nice it doesn't look like that when I brake. I think I learned just watching you!
Many, many years ago when I made bicycle frames at Dawes producing joints like this was the test to get the job but once you were on the production line they expected you to produce smooth joints which did not require finishing. The surface tension of the molten brass helps and holds the material in place. Also if you cut through such a joint you will see that there is a secondary smaller fillet on the inside of the tube creating a stronger joint.
Thank you for sharing that.
"Also if you cut through such a joint you will see that there is a secondary smaller fillet on the inside of the tube creating a stronger joint." A fact that few are aware of. Well fitting and properly preped brazed joints are stronger, more resilient, and less prone to cracking than a TIG weld in general.
My company made race car, experimental aircraft and motorcycle frames out of mild steel [50k psi] to alloy steel [90k psi]. We used Eutectic Brand 1/16'' high silver content brass rod that made a tiny fillet...in and out. However, the joint fit had to be no more than 0.010'' to 0.015'' gap. We used a mill to make the cut to fit the tubes. The brazed joint was stronger than the steel in most cases. The special rod cost 5-6 times normal brass rod, but this was cheaper an stronger as you needed much less gas and rod with less cleanup grinding.
@@lifuranph.d.9440 Why would you make those things out of mild steel and braze them?
If you're brazing anyway you might as well use better, stronger steel like Reynolds 531. There was zero grinding at Dawes, we used standard brass filler rods. The silver solder was only used for pump pegs, lugged 753 frames and such like but that had nearly no surface tension and you needed to be really careful and quick to avoid a horrible mess.
Wow! Beautiful work, it looks amazing. I had no idea that bronze brazing had such strength. I have so much to learn when it comes to welding, brazing and fabrication. Nice job and thanks for showing us how it's done!
What and elegant technique and a beautiful end result. You make it look easy mate !
Very smooth very satisfying to watch.
I had never heard of in line gas fluxing, you learn summat every day. I loved doing bronze brazing, It was always stronger than my crappy welding and it's so quiet and lacking in drama. And once painted it makes you look like the neatest welder in the world.
I wouldnt paint it, id give it a few coats of clear lacquer.
Have worked for 20years now since leaving school as a pipe welder in the oil and gas industry, and that what he's done in this video os some real top drawer stuff!!
This is a wonderful display of skill . The final result looks amazing . I understand that this technique is not always cost effective in day to day engineering but in the workshop where I work I thinks it’s ignorance; they don’t understand the advantages.
Many thanks, well said
Stunning craftsmanship, a credit to you
You voice is clear and concise, your instruction is also.
Don't sweat the small stuff.
You’re like the Bob Ross of welding. I know it’s difficult but you make it look easy.
Haha, the Bobster is incomparable to no man...
Beautiful work, I learnt to mig and gas weld as a panel beater in the 80/90s and always preferred gas. It looks so much better and you have so much more control over the end result and the materials used. What a shame that frame is hidden behind plastic/carbon. Keep up the great work.
AMAZING craftsmanship 😎
Great job! Great video. Looks awesome. Looks professional because you made it look easy.
Love the look of this, I have been watching Paul Brodie do a lot of brazing of bike frames. If I welded like this I would leave the frame raw and just clear coat it.
I used to work in a factory that makes fuel filler necks for the fuel tanks for school buses and I was a braze welder for that. Every piece had to be leak tested by pressurizing and submerging in water tank. No bubbles meant good weld. I welded on average 40 filler assemblies an hour. I had done mig and stick prior to working there but never bronze braze with a torch. Small learning curve to get the hang of it but well worth the experience. Now I use it occasionally in my home shop for hobby work. I must say though, my welds were definitely not on par with yours. Beautiful work!
Watching things like this show cases real skills, most people learn away from brazing but i personally find it satisfying kind of like making a knife by hand you have to practice and learn your metals etc..
That, is a piece of art! Have worked as a coded pipe welder for the 20yrs since leaving school, started off at college with oxy acetylene before going into other techniques and processes.
Only ever tried Tig Brazing and that was only a few times with silicon bronze.
Oxy acet brazing that is one id love to say i can do anywhere near as well as in this video👌👌👌
At long last, i finally found a brazed bike frame video
I thought it was only me who quit breathing when I do things like this, welcome to the club!
You are not alone! 😁
Haha! The lack of oxygen club.
I never knew I could hold my breath that long.
Breathing equals ending your mission 🤣🤣
Same
This takes me back! I used to love gas welding and brazing!
Brazing 101!🤣 Stellar work sir, craftsmanship is not dead!
A lot of patience to do this but the result is beautiful and professional. People are always ripping me about using a MIG, saying it's not good enough. I'm going to point them in your direction from now on. That looks so good I'd put a clear finish on it LOL
Agreed. Clear finish! You make it look so easy!
Dual pulse mig and silicon bronze wire should do the trick
@@danvanmuizenberg6650 I wonder how much the joint characteristics would change?
There's no reason why proper mig isn't good enough for an application like this. Youre just a victim of the know-it-all youtube comment section. The vast majority of those making those comments have never used any welding processes in their lives. I promise you that.
I would prefer tig for the precision but mig will be just fine.
Awesome video! I hate filming myself for the same reason... the voice lol. Don't worry though, everyone's voice sounds bad to themselves. You're voice is not offputting. Keep up the good work!
This is beautiful art sculpting liquid metals. Thanks for sharing!
Good job.Excellent video.Professionally done👍🏻
Absolute craftsmanship and I can appreciate the nostalgia but I could tig it with silicon bronze in about a third of the time with a lot less heat induced stress
Great work, I remember when quality bicycle frames were made like this in the UK using Reynolds tubing, was a big industry.
Beautiful work. Well done.
Superb, great video showing the skill it takes.
Chrome-moly tube & brazing = how light aircraft frames have been built for at least 1 century. The joints are extremely crack resistant where welding wouldn't be.
It’s so refreshing to have someone educated commenting :) thank you sir!
Can i build my roll cage like that?is it reliable as much the tig or mig welding is?why noone uses that technic for something like that?
Yeah but.... there's always a but(t) - materials science & welding technology have moved so far on that brazing is really not required any more, and unfortunately is becoming a dying art. Selecting modern steels & TIG welding can yield much stronger, lighter and yes crack resistant structures. TIG welding properly also inputs less overall heat into the joint reducing the risk of distortion. Brazing still looks bloody lovely though!
@@sakisdalakos6144 no I don’t care what these other guys say it may have been a technique back in the day nothing holds like the use of a tig with filler metal that matches your product. Yes you can mig or tig a roll cage just make sure to bevel your edges to get proper full penetration.
The FAA in the USA forbids brazing aircraft frames. It is not approved due to the sudden and catastrophic failure of these joints. I examined a wreck many years ago that was brazed and saw evidence of brittle failure. The Pietenpol brothers petitioned the FAA for approval and after much testing, they were denied. Adhesion joints are not approved anywhere on the airplane. Look at your SN diagrams.
For a minute I thought I kept seeing a crack in your weld. It turns out it was just the screen on my phone. Lovely lawn chair you're making btw.
I have watched this so many times. Thank you!
Excellent technique, I have a 1979 Rickman Honda with bronze brazed frame. It has done many hard miles and the frame is as good as the day it was made. Reynolds 530 tubes. I enjoyed the video very much, thank you.
THIS IS A T R U E art well done my only problem is after its done I would just want to hang it up and just Stare at it
This is some of the sexiest brazing I've ever seen.
Haha, thanks :)
@@stubbycuts is there a particular reason you would choose this over the superior be strength of a full weld?
@@jonathangarzon2798 cosmetics reasons only.
Nicer if you use tig torch
@@stubbycuts he said, "some of", don't get too prideful. Lol
What can I say? What a beautiful job! A real work of art! Up until 2013 MV Agusta TIG-welded their frames and after painting they looked great. Then they switched to MIG welding and now look like rubbish. Too bad they couldn’t continue with TIG or the more time-consuming brazing.
This is beautiful worksmanship! Really enjoyed watching
Thanks buddy, glad to hear. Cheers
Rickman Brothers built motorcycle frames in the Uk in the 60’s with a technique that must have been similar to this. This is a lost art that you have mastered to the highest level!
Thank you sir, I know Don & Derek from my early days making Metisse/rickman frames (2009-2014) where I got the opportunity to meet some old boys and learn from there methods.. Some of the older frames made by “Pat French” for example where some of the best in my eyes :)
Rickman, Next to know one I know to day even bike rides have heard of Rickman, I had the privilege to have a tour around there workshops and that is how I discovered the gas fluxer and it was all explained to me. The reason I went to Rickman’s was because Reynolds’s were out of 11/8” hardened and tempted 531tubing and they were willing to supply me, They were also building 6 bikes for a Japanese bike company but they wouldn’t say which one, if I was a bike Guy I would have known by the engine because they were all built up, without paint or decals. Great Video 🍺🇯🇪🏁
@@stubbycuts ..do you know Mark Jannink - he worked for Pat French for years and the new owners subsequently. His brazing is pure art.
I have a 1970 Rickman 650 triumph. The welds are great, but the tubing finish was rough when they plated it. Doesn’t look as good as early frames I think.
@@stubbycuts The first bultaco motocross frames were Matisse/Rickman.
Then Bultaco made their own...Pursang [pureblood]...not as good looking.
You're good at explaining the process, can you do more videos please?
I’ve watched this about 10 and it never ceases to amaze me as to how beautiful these frames are,,,
Thanks buddy, very kind. Shame the project ceased eventually
Very appreciated. It did a great job of showing the process and helping to understand. Thanks.
Thank you I can see we’re I’ve been going wrong mine always looks like a molten mess I’ll try and do better
Not to mention the Reynard, Van Dieman, Ray, Quest etc. etc. etc. Formula Fords and other small bore tube frame racing cars made in the UK over the years. Certainly very strong, mine survived my off track excursions! Well done, many thanks for posting this!
We definitely have a successful history with this process.. no worries! glad you enjoyed.
This is ART! I subscribed after 20 seconds!
Amazing, amazing workmanship and result
Cheers, thank you
I love the look of bronze brazing !
Me too! :)
@@stubbycuts I've never saw that process for bike frame. I'm just wondering how strong it comparing to steel soldering. Do you use some particular bronze allow to keep the joint not too brittle ?
@@UPR91 Silver alloys are usually used for bicycles, bronze for motorbikes. (Probably for cost reasons. Bronze is not as easy to get a good tidy result, but the filler metal is much more affordable and slightly stronger)
Respect brother !
Most relaxing video of the week :)
Sick skills. Really pleasing to look at. Awesome job.
Cheers buddy
It's almost a shame to paint it!
You make that look easy 😉
Used to do that 35 years ago.. Mot work ... Enjoyed that hats off decent skill there 💯
Incredible work! Thank you for the video
Hey there! Nice video. I was trying hard to see the actual melted bronze fall onto the frame but too bright. Any filter for the camera make it so the viewer can see what's occurring?
Please make more of these videos.
Beautiful job every bit as good as the bronze welded harris frames
Much respect
Keep up the good work
Thanks, they are done well. Very kind. Cheers
Hey man! Nice job! Congratulations from Brazil!
I had a read of your Description
I had a giggle at your preemptive strike against the it isn't strong enough crowd
I didn't know about inline gas fluxes I'll now have something to google this evening thank you
Excellent quality bronze welding and demonstration. Is an oxidizing flame preferred with bronze welding or can a neutral flame be considered acceptable? I have a jet fluxer and will begin to practice on scraps to get the hang of the technique using Sifbronze 101 - which I have a small bundle of. I'm using 18 gauge mild steel pieces, no.2 tip and 3/32" rod. I use emery to clean the m.s. and then MEK to clean it up in preparation for bronze welding. I'm not expecting to get anywhere near the quality and appearance of your welds, but I'm doing it safely, and taking my time after taking a welding course at my local tech.. Any further advice is greatly appreciated. Have also viewed the gas flux bronze welding of Brian at Arch Motors working on an Ariel Atom frame. British motor racing companies preferred the use of bronze welding using a jet fluxer, and Lotus, Lola, Reynard and many more use(d) it for space frames as opposed to Mig/Tig due to less distortion. Thanks for a very interesting video. A+
Ed Wills wow, if you have experienced Brian Ashcroft on the job, you have seen the master at work.. it sounds like you got all the right stuff to have a go and get practising. All the items you describe sound perfect to start melting some bronze onto steel and just get to grips with how it moves with the heat. It’s really simply after the basic principles of the liquid bronze under heat are understood. Good luck my friend!
Absolutely flawless, from one tradesman to another, respect sir.
Thanks buddy, kind words cheers
Now that is art! Never really understood the pretentious nature of splattering paint on canvas, that doesn't really do anything! This, just by looking at it evokes emotions. I think no one who has watched this video will say otherwise! Simply amazing!
Sir, I am getting into bespoke bike making, rather unconventional bikes, one is a semi prone position and the other is fully covered recumbent, and the last one is a bit conventional but a do it all bike designed to take you anywhere, with just wheel changes. I'd love to have a chat with you about this, if you like the sound of it. I'm a designer and would love those bikes to be a work of art as well.
I wouldn’t paint that frame, looks beautiful as it is.
@@grapeape1508 add clear paint and problems solved
I love this fabricating doing a simular project for my beach buggy build
You make this look so easy and Looks Absolutely Amazing!!! I went to school for Welding and blueprints in 1997, When we were learning to braze, All the Popping and Slag flying like Sparks everywhere, I don’t think I’ve ever laughed that had in my life!!!! Great video
Haha! Yep I’ve been there but in 1999! :)
Fantastic instructional video, Thank you.
Am I the only person who dislikes this guy and his work🙄🙄🙄It is unfair to people like me trying and this dude comes along holds his breath for 10min and brazes a bike frame that looks like it is held by Gold😁😁😁😁Great work ✌🏼✌🏼✌🏼✌🏼
Haha, thanks buddy! I’m sure you’d be doing the same in good time.. ha, best comment yet! 😂
I feel jealousy 😂
Those are beautiful joints! How do you tack the tubes before brazing? Do you put a little tig weld tack on them? I'd really like to try this process on bicycle frames.
Yes on certain jobs I use a tiny tig tac, also small magnets are good at times with tube work I find..
Sometimes a bridge tack could work when small adjustments need to be made. The small wire bridge can be bent instead of breaking or grinding a tack out. Then grind it off when the weld is done
I can see myself enjoying the whole process. Art meets function
Didn't know what this was now I think it's one of the most beautiful things I've seen for a long time 😍
Excellent content. Thanks for sharing. What type/shade lens do you use to view the puddle in the flame?
For brazing I use a shade 3-5..it helps if you are in a dimly lit room with no draft.. you want the joint to cool as slow as possible..
Yup! Agree with this :)
I wish you would have done part of this with a lens on the camera so that we could have seen the placement of the rod and the puddle. I had to do a small piece once for a aircraft class and it took me several tries to get one piece that would pass! Thanks for the video. What is a in line gas fluxer?
There are special lenses for this kind of thing, "Didymium glass", goggles, filter plates, clip-ons. Glassblowers use this also, it cuts out the yellow sodium flare so you can see. NO IDEA how this deals with all the green light from the flux! Gas Fluxer is a commercial product. It's a chunky little pressure-vessel filled with flux, your fuel gas bubbles through it and carries a little along to the flame. Super rugged but of course a little expensive. I once saw one in production, people were silver-soldering all day long, the green flame was really striking. They loved the Gas Flux action and were really positive about it. This was for constant daily use. I want one, but only braze and silver-solder occasionally, so a little regular flux is good enough. Here's a trick I got from an old BOOK: If you heat your brazing rod and put it in some flux (maybe lengthwise, in a little trough)... then gently heat this wire with your torch you can fuse that flux and make it run down the wire in a clear glassy form. So all that bubbling action is done, right? Now your brazing rod has a few inches of a clear flux coating on it, it doesn't make all that mess and confusion when it gets on the work! Just spreads out a little. This is for small delicate work. For something big you can just slather it on there with a brush!
For accuracy like a sniper, you have to hold your breath like him.
Congratulations, nice work!
Amazing skill , flame looked very soft. Great job.
Absolutely stunning, this shows that with patience and a steady hand, anything can be achieved... well almost anything... Now if someone could just post a video of how to please a woman, or at least how to braze their mouth shut, then I could say with complete confidence, that anything is possible!!

Do yourself a huge favor and get yourself a Smith A1A with tip sizes 001, 003, 005...combine it with a set of Kevlar hoses. The whole thing is a lightweight setup and will give you great joy. You dont need the gas fluxer at first...use paste flux.
