There's a ton of videos on YT showing clear shots of TIG welding puddles, but hardly any showing the same thing with bronze fillet brazing. You got some great shots of the fillets being laid down here, nice work.

The man just shares all of his secrets!! All these little details add up to some truly beautiful work😍

This is the most underrated video of all time . Amazing skill and amazing ability to teach said skill

Holy shit I've been waiting for a vid like this for 10 years

Great Lesson Paul, watching the flame with the filter was so interesting, that are great shots. Thank you so much for sharing this techniques.

Am a doctor but I now want to start a DIY bike framebuilding hobby because you make it very interesting with your instructional videos ... thank you Paul!!!

I started this video and can't stop watching... thank you so much Sir

I’m French guy, from France, and I discovered your channel today. I’m completely addicted. When I saw your lesson I would like to return to school and change job. Thank you for the quality of your teaching. Really impressive and I appreciate.

I'm a plumber of 45 years, now retired. I soldered lead and silver soldered copper pipe in my trade. I learned a lot by watching your video. Thank you.

Its so fine discovering how a real artist work ,so much knowledge that he carries throw his life from experience and he gives us here in few minutes for free what he take years to achive .Thank you Brodie.

I could watch Paul Brodie instructional videos all night long. I'm learning brazing right now and he actually shows how to not only make a strong, functional weld, but one that is beautiful, too. I like how he creates a problem and shows how to fix it - great for a beginner like me.

Best teacher on KZfaq! Every second of this video is filled with valuble information at such an indepth level. Thank you!

Beautiful demonstration, thank you!

Taught my daughter about destructive testing this weekend, so the end of the video was *perfect. Thanks so much again Paul!

OMG - he's the Bob Ross of frame building - Zen Master - So much knowledge and patience. Goals!

Master Welder, Master Brazer and a Master Frame Builder. And this is from a Journeyman Pipefitter now retired but still crackin' a 40 hour work week at 63.

This brings back memories. Patience and attention to detail. Commercial and Medical/Research Lab even Nuclear Power construction taught me and alot of others learn these skills. Tradespeople build, learn and teach all at the same time.

This is gold Paul. I recently bought my first gaswelding material but just missed some information to get comfortable with everything. This helped A LOT. You're a hero. Thanks. Keep posting things like this. Greetings from belgium.

Oh my goodness, I've been trying to work out how to set my torch up right for more years than I care to think about. Only now do I see where I was going wrong. This is probably the most helpful video I've ever seen on KZfaq. Thanks both.

There are two things in life I love to do very much and that is cycling and jewelry making. This was such a treat to watch!

Thank you. Please don't stop doing videos. I've been watching KZfaq for years and I have never commented on anything. Just wanted to let you know that I love it and please keep them coming

Epic. Great teacher. He talks about the details that many other teachers kinda gloss over all the time.

As a longtime race car chassis builder I can tell you for anyone who wants to be a master at tig welding , first become a perfectionist at brazing! It will be the most valuable technique you can learn!

I started welding out of necce$$ity, and brazing with Tig was all I've ever done. But now, I have the time to make O/A brazing the next step of my metal joining journey. By a tremendous distance, this is far and away the best lesson of brazing I have ever witnessed!!! After watching this, I can't believe the depths of the slobs that have been trying to show me "the finer points" of brazing! 😂 You're quite the craftsman and instructor. Thanks very much for the great video and inspiration.

Oh thank you for such a well put together video. I've been searching for a video just like this for months.

Thank you for the tutorial and appreciate the information on the part numbers cheers 👍😊

I silver solder a few times a year and It always makes me think about my 1969 Rickman Triumph sitting in the corner. Then I thought about your brazing videos and just had to watch them again! Ive always envied Rickman’s fab skills and now yours as well! Thanks for sharing!

You are definitely a genuine craftsman! THANK YOU for sharing your skills and knowledge.

An absolute joy to watch a real craftsman at his work. Well done Paul!

Wow! Awesome stuff here my friend! Thank you for showing us some of your magic!

I love bicycle history too. That's an excellent little tidbit, thanks for sharing your knowledge!

Wow! I wish I had a great teacher like this when I was younger. Amazing skill.

I can’t explain just how appreciative I am for you and your teaching. Can’t wait to give my first frame a go this summer using your videos as a foundation of knowledge; and some other helpful KZfaqrs! Your channel is also criminally underrated.

Absolutely amazing video Paul and Mitch. The way in which you explain and demonstrate makes you a first-class trainer/teacher and you share incredible knowledge. This is by far the best and easiest to comprehend video I have ever watched on fillet brazing. Thank you for sharing your wealth of knowledge here on youtube.

Mr. Brodie, your videos are a treasure. Thank you.

What a brilliant combination. Fred Rogers teaching style and frame building 101. Thank you

It's -8 outside this morning in Moline IL USA and I'm glad I found this channel. I love this stuff! Build on.

Anyone else watching trying to improve their welding in tech studies?

I'm just gonna hang out here for a while. This is the kind of skilled mentor I've been missing in life. LOL. With all the fabricating, racing, repairs, electronics study I have done online and on youtube....how the heck have I just now found this channel?!?!? Awesome video.

This discipline is so awesome

thank you so much for the informative and rare look into your work!! this helped so much and is greatly appreciated!

Thank you both. Great video.

Thanks very much for sharing your skill and knowledge. Watching you has taught me some key things to improve my brazing.

highlight of my weekend so far!

Hey, as a wanna be framebuilder is really great to see videos like this, somebody who has a lot of experience share knowledge with everyone, is fantastic, many thanks for this series. I never stop learning.

I'm now binge watching your KZfaq vids, they're so comprehensible, informative, and concise. I appreciate the length of each video and the time you take to show your process of machine work(s). it's far better then when I was apprenticing at a machine shop, where their training was basically waving their hands over the controls and gearboxes telling you what to touch and what not to touch, and sprinkling the indistinguishing word, "thing" around like it was going out of style. I can actually review/ (rewind?) your vids as reference points, precisely. Thanks for your vids, excuse the impertinence, but they're a godsend, as far as much information goes. I don't necessarily work in bike or bike framing, but all of your processes still tracks and can still be applied to other metal working disciplines. I have a small home metal shop, and I'm already inspired build machine tool ideas. Again, thanks.

Love the sound when the tube snaps :D

The "Test of Metal" was... Very satisfying.

This is the most educational video I have ever watched about flame settings.

some great info in this video , the hole filling technique is great , not my way of flame setting but the results cant be argued with.

As it’s often said, “every day is a school day”. Great video. I must try harder.

Hi Paul. I'm enjoying your video very much. I am an amateur (hobby) welder mostly using braze welding techniques (Alberta, Canada). Many years ago I purchased a used Allstate Jet Fluxer, and have this hooked up to my U.K. Saffire welding equipment. Although Allstate discontinued manufacture of the Jet Fluxer unit, they still sell the liquid flux for the bottle. I find that post braze welding, I'm left with a white powder residue on the metal that has been joined (similar to your welds), and is hard to remove. In the U.K., many racing car construction shops use an inline jet fluxer, but in a couple of videos on KZfaq showing their method, there doesn't seem to be any residue left on the metal parts (see "Bronze Brazing Moto 2 Racing Chassis" (Triumph frame), or 'Ariel Atom Braze Welding" (3 videos by a welder at Arch Motors U.K.)). How do you remove the paste residue from your welds prior to painting? I find that if you try to undercoat over the residue, it acts like paint remover and bubbles up the paint. I did this last fall to protect the metal through the winter months, and in the spring, found that it had all flaked off showing bare metal (but no rust on the mild steel fortunately!). Secondly, I note that in the video you braze welded 2 pieces of tubing together - one of them being 4130 chrome moly. In my welding course the instructor, and the hand-outs he provided, make note (using 'Never' three times), to ever use any braze welding on 4130. Tom Monroe in his 'Welder's Handbook" and also the late Carroll Smith (U.S. race car builder) advise: "Never braze 4130 steel. Its wood-like grain will open up and let brass flow into it. When the brass solidifies, the steel will then have thousands of little wedges that cause cracks between the grains. Sometimes the cracks will propagate as you watch!" Featured many years ago in a U.S. racing newspaper, a Formula Ford racer in his 80s, constructed a F.F. frame using braze welding technique solely using 4130. It was never followed up how long the car frame stayed in one piece. I am no expert on metallurgy, but I would appreciate your opinion on the practice. Cheers and thank you. EW

Wonderful Job, perfect DIY knowledge base! Regards.

Thanks Mr. Brodie. I am just starting out, and the tips about marking the width, brazing level and moving often and working with gravity are invaluable. Much appreciated!

Great video! So much useful info!

This is a great video. I'm slowly getting back into doing workshop stuff again after about seven years off and did a small garden tool braze repair today just to have a practice. I might revisit it tomorrow to see if I can leave slightly more beautiful.

I used to teach brazing to kids in High School. Great vid and very helpful. Admittedly I never got to do frames like this, just welding exercises and smaller projects. I taught the kids how to cheat by re-melting the braze a bit like you were doing to smooth it all out. The way I did it was a bit more like running a puddle though.

I’ve been working with an Oxy/Acetylene torch for over 60 years. I love how much I’ve learned by watching your videos. Something that I have a hard time explaining to new people to the art is the “balance”. This is a term “Balance” I use when explaining the balance between tip size, gas pressures at the tank gages, type of connection, materials, etc. I’ve never found a textbook or reference to afford these new students of brazing and welding? Granted experience is all I have as my reference, but being able to refer people to a good old school textbook sure would be a blessing for all new to the art.

Thanks for sharing your knowledge Paul!!! It's really appreciated.

best fillet brazing vid out there by far..... i made a glass topped "tube frame" coffee table years ago, IIRC I did not snad the fillets...too lazy! and wanted different look, GREAT video work!

Great work. I appreciate you giving your knowledge and time for free for us to learn. Thank you.

WOW I will study this as I have to make several motorcycle frames and a locomobile frame. I have done it before but you are never to old to learn more.

Love how those reflections in the fillet look like what I want the zebra stripes to look like when designing a carbon frame in CAD.

Lovely work and thank you for the demonstration on how strong brazing is..

Not only is he great at brazing but he's also a very good teacher, that is a completely separate skill that most people do not have. You could be an amazing craftsman but not be good teaching that same skill. The amount of detail he gives is very helpful. That shop is my dream shop, I love the industrial grade machinery, I could build so much cool stuff with that shop. I wonder what kind of metal he's using? It would be fun to make a custom motorcycle frame.

When that tube broke, a part of my heart broke off for a second. But then I realised, it was sacrificed for a good reason. Thank you for this informative and inspiring video 👍

Wow amazing channel. I have been looking for decent length videos on brazing. Thanks a lot 😊 Looking forward to watching the past videos.

Rare combination of gifted builder and gifted teacher. Good stuff!

The craftsman, the art, the legend.

I used to build kart frames and we had inline flux units- much more convenient than brushing on a paste.

An absolute work of (very functional) art!

I am glad to have come across your awesome channel and I must say, you have a wonderful way of getting showing what is actually going on, thank you, Paul Brodie.

Hi from the U.K. - I don't know how I arrived here and I haven't brazed since school (too many years ago), but metalwork was always a favourite subject and this just took me right back. I used to build my own racing bikes as a boy, but from whole frames and components, not from raw tube - great video.

Way nicer than the medical gas brazing I’ve been doing. Hopefully I can find some time this fall to take your course.

thanks for your time and making this

Love your video. I have a 95 Broidi Expresso that I bought new back in the day, the level of craftsmanship is 2nd to none. I love the fact that you are sharing you knowledge with others.

Great video, I work with motorcycles and this is full of very usefull information. Many thanks!!

Killing that poor top tube - you, sir, are an animal! 😈 Thanks for the tutorial, especially on the flame settings ;-)

I don't weld but admire experts thta master their craft

Paul just fantastic work and great videos thank you 👍👍👍👍👍👍👍👍👍

Thank you for showing yor know how! I like your calm way to explain. It's satisfying to wach you brazing :)

Super interesting to see how its done with power tools. I took the Yamaguchi frame building course where we learned how to do it all with hand files. It was a fantastic experience but its very cool to see how its done with power tools.

Always great to watch and learn from a Master. Thanks for taking the time to share some of your knowledge.

Great vid, been oxy/acetyl brazing off and on for a while but never had a good handle on the dance with flame and rod till this vid- very nice, I'll try it- thanks!

Great to see you sharing wisdom with KZfaq videos Paul and in Canada, so cool. I was fillet brazing frames in the early 80s after reading MTB Action mags about yourself, Cunningham, Ibis, Fisher and Ritchie etc' all custom building. Very inspiring to me. Riders on my frames and myself went on to win some Australian national championships from trials to downhill and survived to still ride today. And I still ride my first ever frame! (and a poorer geometry low BB new al frame bought 2nd hand for kicks.) Now, I personally remember juggling frame position and passing the torch across my left thumb to hear the crackle of boiling skin so always suggest wearing gloves but more importantly, I remember doing a whole frame one night and woke with a horrible sensation in my lungs and breathing difficulty. It was due to inhaling the acid gasses of the flux!! I wonder how have you managed to avoid the gasses and not advise wearing a gas mask while welding? Our skill is a rare thing these days and hope we stay healthy to create for decades to come. I look forward to seeing all your other videos now! Personally I've been playing drums since 88 so that's what my channel is full of music, even me playing in my RUSH tribute band Hemispheres. Please check it out it's as deadly accurate as a frame builder's skill should be when playing the music of RUSH! Kind regards from Melbourne Australia.

Thank you for all this content! Best rabbit hole I've gone down in a while. Out of curiosity, what's your rule of thumb/recommendation for regulator pressure while brazing?

Hi Paul, thanks for doing this. I was going to fire up the torch for frame 3 and thought I'd watch a pro's technique first. I am so glad I did! I've never had such a mellow experience working the torch! I normally incinerate things and it's crazy how much more control I had backing the valves way down. And I didn't use a gallon of flux either. Being self taught means lots of bad habits to fix later.

Thank you very much for sharing your valuable knowledge!

Thanks for the vid. I came here as I was looking for bronze brazing in general but watched the whole thing as your teaching skill is as good as your technical skills and are a joy to watch plus the "un-powered demonstrations showing tool motion etc, and moving to the paper for a sketch... an excellent example of why drawing is still a valid means of communication. Thank you.

This is one of those things where he makes it look easy and if I try I would waste $$$ on equipment huh

I'm a firm believer in a bout of fine fingering. It's the only way to get to the required outcome... ... A nice finish. . Beautifully done. Learned a LOT! . Thanks Teach!

I really enjoyed that and learned a lot. Beautifully produced and loved the filter.

The Christopher walken of frame building

I have been welding and brazing since about 1960. Admire your techniques-and teaching skills greatly. You are a teacher for the modern age for young folks (and some of us old fogies). As you show fillet brazing here, is it customary to use a bead of Nickel Silver to get the real joint strength first and then surround that fillet (whether you grind/sand or not) with normal bronze rod? I am not a bicycle guy at all. But, like you (owing to the motorcycles in the background and having looked at your home page)I grew up brazing in the Nickel Silver Motor cycle era of Cheney's, Rickmans, etc. Then one could find Eutectic 16. I don't see it and have no idea what good Ni rod is today. Second, for your small brackets where you mention Silver Soldering, are you using something like Harris Safety Silv 56? I cannot stop watching your vids and are spreading them across the country and to like minded friends overseas. Best of luck with the Aermacchi, equally beautiful work.

Great video! Thank you for sharing.

What a great video. Thanks for this and for explaining so carefully.

Great video! I'm looking to get an oxy acetylene setup in the near future start learning. Are the spiral roll and belt sander necessary? Or is it possible to do all this by hand? I imagine it's all possible, just a lot more time consuming/labor intensive. Thanks for the vids!

Hi Paul, I'm very new to brazing, this video was absolutely great! I feel like I've a lot to learn and a lot to practice. I notice that you don't seem to heat the tubes up so much before adding the bronze, I've heard people say to get it to a cherry-red glow. Can you shed any light on this? What sort of glow should I be looking for before I add the bronze? Many thanks! Pete

wow!!! what a lesson in brazing. you have a new subscriber for life!!!

What a talent! Thank you for sharing!
