Showing one of the original Rocky Mountains was awesome! Amazing to get a small glimpse into Paul's significant contributions in the early days of mountain biking.

[@paulbrodie]

Mark, thanks for watching :)

[@markbrown-us4xe]

Angle the torch in the direction of the weld to "preheat" seems so logical and effective. So glad you shared that. We are all in good hands watching and learning. Thank You.

[@paulbrodie]

Thanks Mark. Yes, often it's the little things that add up and contribute to what we call "good technique".

[@sirnearlyheadlesnick]

Thanks Mitch For the supper Camera Work , and Tomas for being a great student and Paul for your master tutelage

Paul, you have the patience of an angel and I applaud you 👏. I was a paraeducator after retiring as lead mechanic and teaching at an older age is a gift. Blessings to You 🙏

[@paulbrodie]

Thank you Salvador. Yes, I really do enjoy what I do, and hope I can do it for many more years. :)

As someone who is self taught when it comes to framebuilding I always appreciate seeing how the pro's do things, especially when it comes to torch work. Thanks for making this video.

[@paulbrodie]

Thanks Alistair. I too am mostly self taught :)

[@Alistair_Spence]

@@paulbrodie Good point, I guess that's fairly common in the bike building world. A lot of people that had to figure it out for themselves. Probably what I should have said is that it's educational for me to see how someone who has logged a LOT more time building bikes than I have, does something like fillet brazing. How you position the frame, how you hold the torch, the pacing of things etc. These provide a lot of clues as to how appropriate/correct my own methods are.

[@paulbrodie]

@@Alistair_Spence When I was learning, I really did analyze everything to the smallest detail. In the long term I think it paid off. Thanks for watching!

[@Alistair_Spence]

@@paulbrodie Yes, no doubt about it Paul. It paid off big time. You are a master of the craft.

[@836dmar]

Well done, Thomas! Blown away by how easy you guys make this look. Also impressed by the ‘85 Rocky Mountain frame in original paint. How many of those could there be? May not sound like much to many but think about where mountain biking was in ‘85. Guys were still running street frames at the time. Great stuff!

I used a gas fluxer that was inline in the acetylene pipe, very easy to push the flux along as long as the metal temperature was just right.

[@paulbrodie]

Yes, my fluxer is inline in the acetylene hose, and I also use a paste flux. I watch the nickel silver or bronze rod "flow", but I can't say that I "push the flux along"... That's not how it works for me.

[@Paulvx220]

[@tiffinthyme5822]

Hello Paul I really enjoyed your explanation of the technique you use, it seems quite intuitive following the process as it literally flows through. Your expertise is quite impressive to watch and as ever, you make it look easier than it is, obviously it’s something you are practiced in. Keep up these great videos, thanks again to both you and Mitch. Best of wishes Kevin.

[@paulbrodie]

Thanks Kevin. Appreciate your comments!

[@Lecon60]

I was happy to hear you mention the glassy flux. Im consodering getting into doing some larger work. I was teaching jewelers 20 years ago.

[@Lecon60]

Gold and silver really soak up the solder. I've made third hands with nuts and watchers for articulation. I've even worked on furniture. They've lasted 20 years.

[@michaelbanks2357]

Hello Paul, I have been following following a number of your videos for several years now. I have not seen a jig yet that you would use to tack the tubes together. Do you use some kind of jig to hold the tubes in place at the precise angle and alignment while tacking? Your videos have been so very valuable! Best wishes to you as well. Mike

[@paulbrodie]

Hi Michael, If I'm building a frame, the tubes get tacked up in one of my frame jigs. If you check the "Romax" series you will see the frame jig being used for that purpose. Thanks for liking our videos!

[@FernandoRuvalcaba]

Great evening !!! Paul , Delightful video 😄🤩🤩🤩🤩🤩🤩🤩always nice to see you , teaching us 🤩🤩🤩🤩🤩😇😄😄😄😄

[@paulbrodie]

Thank you Fernando :)

[@mopedmarathon]

Great to see skills being passed on. I admire your teaching ability’s. Could the black oxide on Thomas’s joints be from removing the torch too fast or too far slowing oxygen to contaminate a still liquid puddle? I noticed he held the rod in his mouth a few times. Maybe there was some moisture on the rod that caused it. Glad to see you’re getting stronger and stronger. Thanks for taking us along for another day in the shop!

[@paulbrodie]

Thank you. I don't recommend holding the rod in your mouth... The "black oxide" is probably from a bit of excessive heat, causing the flux to turn color. I don't think it's from removing the torch too fast.

[@JohnnieBravo1]

Holy Cow, Paul! I think you have more hair than ME now! Awesome! These brazing series really help me understand what the goal (and the process) is. The best part of my brazing and welding, is the grinding afterwards.

[@paulbrodie]

Yes, my hair is slowly coming back. I'm happy! :)

[@bulgieR]

Paul, another fantastic video, thanks a million. One Q: at 4:25 you say as the flux gets close it starts to get opaque. Did you maybe mis-speak there, meaning to say transparent? That's my experience: it starts opaque and then turns transparent when it reaches its active temperature. Don't mean to nitpick just want "clarity" (haha)

[@paulbrodie]

Here we go with words again... In my mind, I did mean to say opaque, because that's what it looks like to me. My way of describing it. Who knows if we are even using the same flux? Another word I could substitute is "glassy". I think it is up to the brazer to interpret the change in the flux, and relate that to the temperature of the steel. It is not easy to actually explain the subtleties of flux and metal coming up to brazing temperature.. Thanks for watching!

[@gerry343]

Many years ago I worked making racing kart frames. We used an inline fluxer on the acetylene hose, which saved the trouble of painting on the flux. It was most important to have the tubes clean and free f any scale or other contamination.

[@bulgieR]

Pretty sure Paul uses a gasfluxer in addition to the paste flux. Me too, gasfluxer + paste. I have laid down miles of fillet, and never wished there was less flux on it. EDIT: yeah I see elsewhere in these comments Paul states he is using a gasfluxer + paste.

[@paulbrodie]

Yes, clean tubes really does help...

[@paulbrodie]

Exactly. Gas fluxer + paste flux = perfection :)

[@tomfortson2684]

Hey Paul & Mitch, and Thomas, very nice lesson on fillet brazing! I like to see how the fillet blends. You're a much better teacher than my college prof (back in about 1969).

[@paulbrodie]

Thank you Tom. It was fun making that video. I had a lot of crappy teachers years ago, and that inspires me to be the best teacher I can be...

[@Mad-Duk_Machine_Werkes]

From my angle, it seems like (speaking in TiG terms) Paul DIPS his filler rod, and Thomas seems to do more of the "Lay-Wire" technique -

[@paulbrodie]

Yes, my torch is hotter and I do melt the filler rod much faster..

[@bigbird2451]

@16:48 Mitch what are you doing 😂 You're supposed to be filming not trying to dip your rod into another man's puddle! Come on now, this is supposed to be family friendly content here. 🤣🤣 Great video as always Paul, thank you for uploading! 👍👍 I think he accidentally messed with the gas mixture, when he first tried the pencil grip his fingers went in between the gas knibs, so maybe the mixture was off and that's why he had the black specs in the fillet. Tons of helpful information in this video! 👌

[@paulbrodie]

Thank you.

[@GreggMax]

These brazing videos are great! Question, what size torch tip are you using here?

[@paulbrodie]

Thanks Gregg. I am using a zero tip. Sometimes I switch to a "1" tip for more heat, but mostly zero.

[@opieshomeshop]

Hi Thomas! *_You're lucky to have the OG teaching you._* _Only thing I'd say is keep your fingers away from the valves on the torch._ Otherwise, good job. You're miles ahead of me. Best I can do is watch the videos here and absorb what I can. KZbin university. Good luck to you down the road Thomas.

[@paulbrodie]

Thank you :)

[@Manandmachine772]

Love the tutorial videos

[@jcnpresser]

How many frames does the average guy braze before he has a good one? I feel like those small test frames would be awesome for a fellow to practice on before starting on a actual frame.

[@paulbrodie]

Yes, practicing on the small "baby frames" would be a great way to learn how to braze. A good frame is more than just great brazing, however. Frame alignment is very important too, and I feel that not many builders take it seriously enough. So, how many frames...? Hard question to answer. I know that I felt like I had a breakthrough with alignment at around frame #300...

[@19672701]

Do you ever use a gas jet fluxer? Was watching a Ariel Atom,and i think Stubie Cuts braze.

[@paulbrodie]

Yes, I use the automatic fluxer all the time. It was working for this entire video. That's why the flame is so green!

[@markkraus3598]

Hi- could the brazing be done over a welded ( either MIG or TIG ) joint also ? Do you have a video following up the brazing showing how to smooth out the joint ?

[@jimgourgoutis]

Lucky guy! How do I get a private lesson!?!?😁

[@paulbrodie]

Yes, you could say that Thomas is a Lucky Guy! Being a friend of mine is probably the best way to get a private lesson :)

[@ductrung3993]

Hello Paul! May I know what adjustments should be made when fillet brazing thin tubes (0.7) are have also been heat treated please? Thank you!

[@TheMobileBoatwright]

Hello Paul, Another Great Video. Paul, I've got a Steel Nishiki Roadbike Vintage 1978. I've ridden it hard through the years and have had an accident or two. I feel that the frame may be twisted. Is this something that you could correct for me if I were to send it to you. Last time I road it the bike wouldn't ride straight hands free. Let me know what you think? Paul Maselli

[@paulbrodie]

Paul, shipping is very expensive, so it would be much better if you could locate a framebuilder that is close to you. Especially if you are not in Canada, then there is all the border paperwork...

[@TheMobileBoatwright]

@@paulbrodie Hello Paul, I appreciate your honesty. I just took a closer look at my bike and found that my forks were tweaked to the left it was not the frame, my front wheel was off center. I recall a racing accident about 40 years ago that must have caused this. I haven't ridden it much since then so finding this was a surprise. Following your lead I applied some judicial force with the forks in a vise and re-centered the wheel. She rides so much better, almost like new (under a 60 year old body LOL). Anyway I think I'll consider the repair a success, and ride her as is. Thanks Again, I'll keep watching and get you and Mitch some Coffee..... Thanks, Paul Maselli "TheMobileBoatwright"

[@paulbrodie]

@@TheMobileBoatwright Glad you were able to fix it yourself!

[@richard0crewe]

It's it possible to build frames by TIG brazing? There are cheap inverters for about $60/70. They would reduce the entry barriers for frame building.

[@jimurrata6785]

What are the relative melting temperatures of silver and bronze rod? I call that a scapel grip. (Think its more like surgery than drawing) Thomas learned a lot, and did very well. Id be incredibly nervous with Paul hanging over my shoulder! 🙄 And, once again, Mitch did a fantastic job juggling camera and filter, giving us a great look at flame and flow.

[@paulbrodie]

Thanks Jim. Think you mean a scalpel grip. What are the relative melting temps? I would have to look that up, as I do not know off the top of my head...

[@jimurrata6785]

@@paulbrodie Yes, I do. 🥴 I assume there's enough delta that the silver doesn't turn to water if you slightly overheat the bronze joint like Thomas did. Thank you for the lesson!

I think, that Rickman frames were bronze welded. Then nickel plated...

Sif bronze or silicon bronze on the Rickman frames. A local frame maker near me worked with the Rickman brothers . I don't have a gas welding set up so use this guy for any alterations or repairs. It's nice to watch.
