How To Braze - Tips and Tricks with Paul Brodie
HTML-код
- Опубликовано: 27 сен 2024
- I learnt how to braze in Grade 8 Metalwork. I knew I had discovered a new world and jumped right in, never losing my enthusiasm to this day. I'm self taught mostly and this is what I know. If you have any questions, post them in the comments below.🤓🏁

Great watching a skilled person demonstrate and talk in such a relaxed and eloquent way. Something very ZEN about Paul. Thanks
Thank you Dick. Appreciate your comments.
Great Job. I am a retired vocational instructor and I have been looking around for a video to teach me brazing. Looked at a lot hackers, but you have done an excellent job , Thank you.
You're an inspiration to me, Paul Brodie. I got into metalworking just last year, and I realized I don't want to be an ironworker, I want to be an artisan, like you.
Well thank you very much. That's a very nice compliment. I hope you do work at it and become an Artisan. Remember, it does take time. I have been at it 57 years...
I was just practising fillet brazing and stopped to take a break and think about what I was doing wrong and right and saw your video, perfect timing. Great video. Thank you
I have never done this process or even had it explained to me until I watched your channel. I just built myself a cargo bike for riding with my dogs and I used flux core for everything, its ugly but works. I'd like to be able to learn to braze, first I need to invest in that equipment. But I need to own a torch anyway. Thank you for showing me why I need it soon lol Thank you for sharing your skills and knowledge, you're a very good teacher. I appreciate you
Thank you Michael. Very nice comment!

I think stalagmite would be a better descriptor than icicle on the braze stacking. I've been welding as a hobbyist for 47 years and never heard of an inline fluxer. That is kinda neat. Don't think I would get one as most of my welding is tig or mig but brazing has always been kind of relaxing to do. Bought a jewelers torch awhile back as I have always liked making little sculptures. Currently gearing up to do metal casting as one bucket list item is to make a 1920-ish Indian from scratch. Which is why I started watching your videos, when I found the Whippet video. Thank you so much for sharing your knowledge!!!
Roundtuit, thanks for watching and commenting.
My favorite gas brazing video
Thank you Gary.
I put in a search for Brazing - the first lasted about 15 secs before I got bored with introductions, etc...
Next was Dude teaching in college, making bronze trees... That was cool, but not so informative.
Then here...
.
I like your teaching style Paul. Calm, sensible, informative, even the background music was toned down, so we could hear clearly everything you said.
.
I can solder, arc/tig weld, but it's been awhile since I brazed my home (ship)-built morse key and needed a bit of a refresher before I tackle an upcoming small brazing job. I was not disappointed. Subscribed.
Thank you Deebz270. Welcome to our channel 🙂
Thank you so much Paul. I learnt to Oxy Weld a lifetime ago but have been using a MIG for the last few years. On the back of finding your channel I am off to buy a small oxy set and start repairing a few frames that I have been sitting on for too long. Thanks again. Jeff
Cool, got you going, eh?
@@paulbrodie For sure my friend. Going to practice my brazing and replace rear dropouts on two of my BMX bikes plus fabricate some bits and bobs on my Honda CT110 race bikes. Just need to get a lathe now (hahahaha). Back in the day, my late Dad was a machinist / fitter for Clyde Engineering in Sydney Aust. Keep up the great work and looking forward to watching more of your content. I will give your channel a shout out on one of my shows "The Postie Bike Podcast" ..... have a great day. Jeff
Hi I used to build frames with my father George Longstaff in the UK 🇬🇧 very nostalgic video for me .
We only used the liquid flux in the gas for fillet brazing for a smoother Finish and kept the frames in multi directional spinning jigs when brazing to help keep them in line . The noise of the dyno file brings back memories. We built bikes ,trikes tandems & tandem trikes . Happy days google George Longstaff we built the first ever 2WD mountain trike . 😁
Yes, you definitely have had a lot of experience! Building trikes and tandems is not for the faint of heart. They are definitely a lot harder than a regular hardtail. Thanks for watching and commenting!
Love it! Thanks. My background is with industrial batteries, a lot of welding lead. Years ago I learned that it was important to not have too much oxy which is what you called “oxidizing”. And what you called “neutral” I called a soft flame. Awesome channel, I’ll be back!
Thanks for watching and commenting!
What a godsend! This information is gold! Why doesn't this channel have a gazillion views and subscribers?!? People need to wake up! This video alone gets a Like/Subscribe/Bell
Thank you very much. We are slowly getting a little recognition...
@@paulbrodie "The Flux Capacitor is what makes time travel possible."😉
Thank you Paul. I found this video immensely helpful as I try to learn brazing myself through trial and error through reading books, watching videos, and of course bugging my friends who have built frames. Your videos are extremely helpful and informative and will serve as valuable resources for anyone. Many thanks.
Thank you Ben. Very nice comments!
WWBD? Man. Much love and respect. If you ever want to build a bike. I have a desire, need and a historical reference to build from.
I'd say that your automatic fluxer was a good investment, you got that the same year I was born, lol. I'm just starting out learning how to braze, I've never done any type of metalwork before, but this has always intrigued me. So thank you for the video, it was very informative.
A lot of folks don't want to pay for an automatic fluxer, but they really are a good investment that can literally last a lifetime. So glad I have mine. Thanks for watching our video.
Great video Paul, thank you. It reminded me of nearly 60 years ago junior high shop class.
Thank you Edward. I remember High School Shop almost like it was yesterday!
I've fixed torches the last 10 years and I finally picked up soldering the cutting heads. Thanks for the tips!
Thanks for watching!
Tarantino needs to make a movie in which some serious sh*t goes down in a metals shop just so that he can cast Christopher Walken to play you, Mr. Brodie.
And, btw, great video! As a person who’s always been interested in this skill but never pursed it, I find your presentation engaging and easy to follow!
Thanks very much! Christopher Walken has been mentioned before, somehow... I like him as an actor. And thanks for liking our video....
hey Paul, ill be travelling to the UK for a frame building course, and now watching this to get me a little up to speed! making me so excited to start out!
Good luck with your frame building course. Thanks for watching!
I've recently started to play around with a cheap mini oxy-acetylene set from the hardware store. I use flux powder that I got for free from a company that quit brazing. I mix it with deionized water to make a sticky paste, which works quite well. They sold me some nickel silver cadmium rods for scrap price. (Yes, I have good ventilation. Safety third.) I braze scrap bicycle frame pieces for practice and I dream to make a freak bike some day. It doesn't need to be very tough, just tough enough for some show rides. What I wanted to say though, is that you can clearly see when nickel silver cadmium melts, because it's a little dull when solid but becomes mirrorish shiny when molten. That's a really nice indicator.
Yes, you certainly are doing it on the cheap. But it sounds a bit sketchy to me. You say the frame doesn't need to be very tough. I disagree. You want to overbuild it, so it NEVER breaks. Also, buy the best flux. It's all detailed in our second brazing video. Flux is very important. I use nickel silver, but not nickel silver cadmium.
@@paulbrodie thank you for your reply, Paul. You're absolutely right with your attitude, always to overbuild so that the bike never breaks. What I wanted to say, is that my frame will never be used in a mountain biking application. It will be ridden on smooth flat pavement, with no competition whatsoever. But you can be sure that I won't bet my life or my health on bad craftsmanship.
The flux that I got is intended to be used with my particular brazing rods. Someone, who has more knowledge in brazing than me, thinks it's the best for the application. I guess I'm the weakest link in the chain 🤷♂️
@@andrebartels1690 Then I say, Don't be the weakest link in the chain. That doesn't sound good to me,
Nice job Paul.
Thank you.
WOW...great instruction! I learned more little things from you in the time spent watching this vid than I have learned in years of messing around with brazing!! As I have always believed when doing many types of work, the ease of doing the job AND THEN quality you produce is in the DETAILS!! THANK YOU!!
Thank you Don.
now you are doing real brazing. a number of videos on YT are entitled "brazing" but they are doing silver soldering. i learned brazing at 16 or 17 before i learned to weld. a close neighbor showed me how to braze correctly, he worked brazing at Pratt and Whitney jet engine division
Yes, I have heard there is a bit of mis-information out there on RUclips!
You built E.T.’s finger not an icicle. ‘Elliot’
Thanks for the tips and your delivery is pleasant. Its important to be pleasant as a teacher. Some people are a wealth of knowledge but ruin it with poor delivery. Thanks again.
Thank you Sir Mixalot. I do my best :)
You have very nice speakers in your shop! The amazing sounding KEF Reference 101😍
Yes, I bought my Kefs back in 1980 I believe...
@@paulbrodie They are on my wishlist. 😃
Enjoyed the video thanks for your time.
Daniel, thanks for watching!
The best presentation ever! But that music killed it, John
This is an excellent video, Paul, thank you for making it. I want to improve my brazing skills, and I've been practicing with icicles, but it is quite challenging to do these, without a self-fluxed, and using 15% silver rod. Probably not the best rod for this trick, I reckon-I need to get some others to try.
Thanks for liking our video. Building icicles can be tricky, but don't give up. Silver content can be expensive, so get bare bronze rods, I use 3/32". The automatic fluxer is a great help too, but I know that not everyone has one...
Thanks for the video Paul you've taught me a lot. I have no intention of ever building a bicycle frame but I do need to learn how to braze and weld. This will get me quite a ways down the road. I have a project where I need to stick some round tubing on a piece of angle and this should allow me to do that. Keep the good stuff coming.
Thanks Johnny. We're planning another fillet brazing video in the next while, so that is upcoming.
Hey Paul Brodie! You're back in my feed! Nice! Great video! I had never heard of an automatic fluxer before and I've been brazing for decades. Thanks for the tip.
Usually what I've noticed when people think about lubricating an oxygen bottle, it's those coarse, rusty threads the cap screws onto. I just scribble on them real good with a pencil and let the graphite go to work. It's an old woodworking trick my grandpa taught me. (He did it a lot on the top surface of his table saw. ..and tight door jambs and hinges ..and on the pieces of our fishing poles that sock together. ..). I'm going to be making ice cycles within the hour. I need that kind of practice. I notice my brazed joints look a lot like my soft solder joints with not much stacked up
I'm so glad that we are back in your feed! And thanks for liking our videos... I would use wax on those big coarse threads...
Just got a job in hvac install great help
A good well explained video
Thanks John!
Paul. I just made my life complete…. I ordered me a Romax steel g 😊😊😊😊
That sounds ike a good thing! 😉
Very informative.
Thanks Paul. Much appreciated.
No worries, thank you.
I enjoyed your very pleasant video, and probably, (hopefully), learned something. Thank you, Sir!
Thank you Bill :)
Also interested in surface prepping suggestions as it helps with whetting and capillary action and contamination that acts as an anti-flux. Great video once again, thanks!
I sanded the pieces with 80 grit emery cloth..
Your bracing-skills are excellent, Paul! As are your skills in general. Beautiful creations you make, and your explaining is pare none. Say hello to Mitch
Thank you Helge. Mitch reads the comments too :)
Paul you are a great instructor, very through. It[s a pleasure learning from you. I subscribed and am looking forward to your videos
Thank you Jackie. Appreciate your comments!
Excellent video!
Great video and tutorial, thank you!! May I ask what shade of glasses do you use -- 3 or 4? I mean, IF you were thinking safety first instead of 3rd ;-) I've been looking for 4 but can't find any, using 3. Thanks much!
Ryan, thanks for liking our videos. I inherited my brazing glasses from my father; he used them in the UK in the early 60s. I have no idea what number shade they are, sorry.
Always a great way to start the Sunday! Very nice content, as always. I really apreciate this work thank you so much.
Good stuff.
Thank you!
Very good on illustrations very good teaching
I learned to braze with coat hangers and steel tubing, the melting temperature is close but the large steel tubing acts as a heatsink, it's not the easiest in the beginning, but eventually things are figured out, the steel coat hangers I'm guessing are low carbon, since they are so soft, probably has a lower melting temperature also, not the worst thing to do , and it wirkd
I'm glad it wirkd for you. Thanks for watching.
Hey Paul, I can’t believe it took me this long to discover your channel. I have been a huge fan since I was a kid in the 90’s. I’ve actually been in the basement where (I was told) you first started making bikes professionally.
Tyler, thanks for finding our channel :) That house address is 740 E 22. Same house?
@@paulbrodie That’s it. I was doing some electrical work there, way back in the day. It was pretty cool seeing all the old stickers.
Was wishing you had a brazing starter video, so thank you!!!!
Great video and camera work Paul and Mitch. I learned a lot. Where did you get your welding glasses Paul?
Thank you. They were my Fathers brazing glasses from the 1960's. You probably can't find them anymore...
Are your glasses blue lens?
Thank you Paul. Very informative for me being newbie.
Thanks for watching!
Enjoyed this Paul, nice to have found you, ive subbed 👍
Thank you Ralfy.
Thank you Mr. Brodie, very informative.
David, thanks for watching... 😉
Thanks so much, you explained it so well!
This is great - perfect timing in my journey! Will you be doing something on fillet brazing some joints on a frame? Weld order; amount of brass to aim for; and even how to file down would be great. Your videos explain things much better than I have seen anywhere else! Thank you!
Watch the rest of his videos! All that info is in there!
Yes that is the plan..
Silver brazing some cable guides today. I've only done it a few times so nearly no experience, especially with tuning a proper small flame. This is just what I needed. Thanks Paul!
- "some of those RUclips videos where the flux is just piled on there" - lol that's me haha. :D
Silver soldering or silver brazing? I always silver solder cable guides. Just remember to keep the cone very close; it really does make it easier.
@@paulbrodie Yes silver soldering. Thanks for the tips!
Thanks. You make it look easy!
Thanks Ben. Part of my job is to make it look easy!
Just a thought,
Turn the heat brick on its side, then drill multiple hols in it and have some 5mm studs made up that protrude about 20mm (3 quarter inch ) then fit the studs depending on the job in hand.
Theñ rest the job on the studs.
That way you waste no gas heating the brick up.
Well, the heat brick isn't taking up that much heat... but it's great that you were looking for a solution :)
@@paulbrodie Spoken like a true college professor. :-)
@@Deebz270 That was my life for 9 1/2 years :)
That’s very nice video, thank you for the teaching.
Thanks for watching.
Great introduction! I’m starting a gig in Automotive restoration, and will need to learn how to braze. This is a great way to get an idea and I’ll be spending after hours hopefully practicing myself! It reminds me of soldering, which is an art unto itself.
Brazing could be useful in auto restoration. Years ago I used to work right next to an auto body shop that did a lot of resto work on MG TC's and such. Not so much brazing, but tacking with the Mig torch when patching rusty panels etc. Good luck, and thanks for watching....
Your awesome sir... Music helps
Glad you think so!
Thanks a lot for this educational sharing !
Excellent video
thanks for the great refresher Paul. Happy New Year
Happy New Year Lance!
Best damn video,,,,,,more videos please
Thank you Tony.
I'm just starting to mess around with brazing and your content is amazingly clear and useful. Can you point me to any videos in actually welding thin metal using the same process as brazing?
Thanks Mike. We did 3 videos on brazing and silver soldering. What other videos are out there (similar, but welding...) I do not know, sorry. Just do a search as see what pops up...
Great Video from a great person. Can you make a video on building and using a Bob Beck protocol. The excuse "I've never done that before", won't wash I have watched other videos of yours. Good luck.
Thank you. I've never heard of Bob Beck, so I would have to Google him to see What's up!
Thanks for the brazing lessonl Paul! I have to make a tension spring for the Tom Richie inspired belt sander then its finished,
l'll send ya a pic.
Thanks! Might be easier to buy a spring rather than make one...
@@paulbrodie Thanks Paul, I decided to build a spring to fit the shape of the tool a little better. How can I send ya pics? you have an email I can send them to? I dont have facebook or instagram
@@rickfazzini22 fussyframebuilder@gmail.com
Here goes nothing lol
You said the heat pulled the solder to the I side. The only thing I've ever done was sweat copper. And I was told, you only heat up the out side peice, then wants the solder starts to melt the inner peice pulls the solder in..
I didn't know if copper and the metal your soldering would be the same. It just got me wondering if I was told wrong many years ago lol
O and I Thank you for the video!!!!!😇
There is some truth to what you said... that is for soldering. I was brazing, which is different. Different filler rod, different fuel, and different techniques. No, I can't say you were told wrong all of those years ago. Thanks for watching...
So much thanks for this video. It helps me a lot as a starter!:)
2:48- A before O or else you blow!!
THANK YOU!!!
Hey Paul, Thanks so much for all of your videos! At one point or another I saw a clip where you talked about which specific type of Nickel-Silver rod you use. For the life of me & after re-watching half or more of your library I cant find that clip.. Can you share with us the type & content of Nickel-Silver rod you typically use? Thanks again & looking forward to more videos!
fwiw, I settled on 1/16" GF72 nickel silver brazing rod from the gas flux co. Not sure if this is the same thing Paul is using, but its what GasFlux folks recommended, so I'll try it out. Thanks again Paul! We all owe you a debt of gratitude for everything you've shared with us on this channel! Looking forward to everything that is yet to come!
Just found your channel great veiwing
Thank you Barnaby....
Thank you for making these videos Paul!
Thanks for watching!
Hi Paul, i wish i have found your channel before! Great contents. The explanation of the flame type is what i was looking for. Would be cool if you can film it with a proper exposure in order to see the variations in shape. Ciao!
Yes, hindsight is 20/20. We'll do that in the upcoming fillet brazing video :)
@@paulbrodie great!
Got an oxy-acetylene set up in the garage recently and was playing around with the flame color and cone length. Initially there was a gap between the flame and the nozzle when i opened up the acetylene. For the life of me I couldn't release oxygen without flame shutting itself down. Re-visited this video, reduced the acetylene flow, brought down the gap to the flame and added oxygen slowly to get a beautiful blue cone. Thanks a lot, Paul (and Mitch). Small things like these are super important for a learner to take each step forward. Keep up the great work. There's no other resource with this level of detailing on RUclips for us, garage learners.
Sorry it took me so long to find your comment... Yes, it sounds like your acetylene was open too much, but he figured it out.. Thanks for liking our channel..
@@paulbrodieThanks for the reply :) In the meanwhile, your videos have helped me to reach the last legs - seat stays - of my 1st bike! And I am sure there are many others like me :) Thanks coach!!!
You are most welcome. Seatstays are not easy, and I too struggled at first. That's great you have almost finished your first frame. Congrats! And thanks for watching...
Great job thanks - everyone here braising exhausts onto chainsaws
Hello Paul, First my comment, you are a master at your skills Sir, Thank You for sharing. I too have worked with metal (and wood) all my life, as a Tool & Die maker, Machinist, Engineer, and Boatwright. We are probably contemporary by age. My questions, do you always use the line gasser for flux, You always add paste flux before heating so are these being used in conjunction with each other? Have you ever used an Argon shielding gas with the oxy-acetylene as an inline flux? Your shop is nicely set up, please offer up a video tour one day Thanks, Looking forward to your response
If I am brazing, I always use both fluxes. In conjunction with each other, works very well. I have not used an Argon shielding gas.You are not the first to ask for a shop tour. Thanks for watching!
@@paulbrodie Thanks so much for responding so quickly. Do you ever work with braze rods that are flux coated (silver, nickel silver or bronze?). I'd like to know your opinion on using these fluxed rods instead of bright wire and paste flux. I tend to favor these for my marine fabrication as well as casting repairs. I also find it interesting that you work in both SAE and MM. Most of your shop dwgs are in SAE while you measure your frames in MM and use metric threads. Is this a function of the bike industry being MM standards? Or just because when we started out so many years ago the Imperial system was what we were taught? I'd also like to ask where you are located? Thanks Again, Paul Maselli "TheMobileBoatwright".
@@TheMobileBoatwright Flux coated rods are ok if that's all you have, but I prefer my system of paste and automatic fluxer. I was taught Imperial and then Metric showed up. Bicycles are a mix. The tube OD's are Imperial, yet the wall thickness is Metric. I am in Langley, BC, Canada, eh? Thanks for watching!
Great Vid, many thanks.
Thank you BL...
So informative. Really appreciate guys taking the time to share this kind of stuff! These skills are something to be really proud of. No matter how advance technology gets I think there will always be a need to join one piece of metal to another.
Yes, the world will always need welders. Thanks for watching!
@@paulbrodie And that’s no bad thing 😂
looking forward to seeing more and getting started myself. 👍
Hello friend, I'm from Brazil and I really liked your explanation. I intend to make an exhaust for motorcycles and I want to use bronze brazing, do you think it is a resistant solder?
Hello Brazil! If you braze the tube to the header pipe flange, that is fine because of the size of the fillet. But brazing one tube to another of the same size, is not a good idea, because it is likely to crack or fail. If the tubes are different sizes and one can slip into the other, that will work because the braze can flow in between the (2) tubes. I prefer to Tig weld my exhaust systems.
Excellent explanation of the process, but it would have been a good idea to film through black glass at the begining, because frankly, I can't see all the nuances of the flame you're describing, even with HD. :)
You're probably right. It's not easy filming flames. Thanks for watching.
Don't be sorry, I watched the following one where everything was explained again with filter. Very helpful.
Thanks for teaching.
👍
Paul, love the video. I, too, have gasflux. What do you use to get rid of the residue? It's like glass
Thank you Paul. The flux I use is water soluble, so soak the part in a bucket of hot water, or run hot water over the flux...
Without a huge investment in equipment, what are your thoughts on using MAPP with a torch on a hose with maybe a fluxed rod or powder? Obviously, not a production option but for practice and light duty?? Thanks for all your lessons.
I have never used MAPP so can offer no opinion whatsoever. Sorry. When I first started brazing in high school all we had was flux coated rods. Oxy-acetylene really is the way to go. Thanks for watching.
Paul, thoroughly enjoying your videos, just subscribed and would like to ask did you make that gas fluxer?
I'd like one but can't afford the one from "ELYRIA" which, in the original Etruscan, is actually pronounced "Springfield".
I did not make my fluxer. I paid $800 Cdn in 1985, so it was not cheap, but I have never regretted making that purchase. In theory, it would be easy to make, but if there ever was a fire, and my insurance company found out I had made my fluxer, that would be a big problem. The fluxer from Elyria needs to be modified, IMO, to make it work properly.
@@paulbrodie Insurance.Excellent point. Are the modifications anything you'd care to discuss here or might not that also void insurance coverage?
@@greybeard3759 I cut the reservoir chamber in half and welded in a 4" extension. I believe the OD is 6". Then I also extended the inner tube that much too. Now the fluxer holds a lot more flux and actually works properly. I did this to all (4) fluxers at Framebuilding 101. Never had a problem.
I think, than people apply more flux in brazing area when they don't have flux mixed in flame
7:48 “For the rest of the video i don’t think im gonna wear gloves, cuz, im gonna be very careful. Not gonna burn myself 😎”
22:12 “Thats hot😐”
Good thing you were paying attention!
@@paulbrodie All jokes aside this video was extremely informative and every question i had its like if you knew and answered it within the next minute! Thank you Paul for this🙏🏽😊
Blessings to you and your family this Sunday🙏🏽
@@brianaguilar9782 Thanks Brian. I'm glad you enjoyed the video...
A little off topic, but this looks to be a viable way to "mold" and shape a motorcycle frame (1960s H-D chopper). I did not want to use lead or plastic body fillers on this build due to the toxicity of lead and normal body filler will crack. I am aware that the frame itself will be a huge heatsink so I have separate non flux tank setup with rose bud for preheating of larger areas, Similar J28 setup with smaller tanks for brazing work. Any body think Im crazy? I have another Harley frame to practice on beforehand. Material costs more expensive, but I need it to last.
Great tutorial. The gas Flux company is located in Elyria. (E leer E a) not too far from my house.
Thank you Spike!
Love your work sir
Thanks Paul. I'm planning to build a large scale model RC airplane (about 4M span) with a brazed chrome moly tubing fuselage with tubing ranging from 3/16" to 1/2"' diameters. Is there a simple way to create the form fitting joints of smaller tubing? Also, I would like to use a Oxy-Mapp torch I have on hand vs.a Oxy-acetylene setup. Pros and cons? Thanks.
If you have a milling machine you can make a fixture to hold the small tubes and then mitre them with an end mill. I have only ever used oxy-acetylene, never mapp gas or propane. Sorry I cannot advise you on that...
Thank you Paul very informative
So when you solder do you do one joint at a time? When do you reflux a joint? If it gets too hot do you start over or just wire brush it clean and flux it again? When someone has brassed a part and you want to weld it. How do you get rid of the brass?
Paul, can I use an oxyacetylene torch to repair a bronze statue using a silicon bronze rod? Most people use TIG welding, but it just too expensive for me. Everyone talks about bronze brazing, but not bronze brazing BRONZE. I wonder if it’s not possible because the statue and the rod have the roughly same melting temperature. I want to use silicon bronze filler rod, because the bronze I used in my sculpture is also silicon bronze. This should create an even patina and hide the repairs.
Good questions! I have very little experience brazing and repairing bronze, sorry. I suggest trying a very small amount. That will give you an indication if it wants to, or not. Remember to clean everything very well, adjust the torch properly, and use clean flux.
kool
Thank you...
Thanks Paul, for the great instructional videos, Stumbled across the 'Romax' build whilst doing some research and have now binged lots of you videos......GREAT STUFF! Done my fair share of silver soldering on all sorts of small machines, clocks and braze on bike bits. However, Brazing is a different animal. Having trouble finding the right supplies here in Australia.....any suggestions? aggh! (hate those pre fluxed rod!) and in need of bit more practice before tackling the brazing on the frame. Love all the motorbikes in the background. Cheers from Oz Trev-(R)
Try contacting my friend Rob Benson at Tempest Bicycles and/or Chimera Frame Works. He's building so should know local suppliers. Thanks for watching!
I have learnt so much in such a short time. Thank you such a great video tutorial. In one of your videos you silver soldered the joint and then brazed over the top to produce a lovely blended join. is the Silver solder there for strength or some other reason. Hugh
Hi Hugh, if you look through the comments you will see that I have answered this issue many times, and I talk about it directly in the fillet brazing video. You are confusing silver solder with nickel silver. They are completely different! Silver solder melts at a much lower temperature, and usually has a content of 45% or 56% silver. I use nickel silver from Soudotec and the part # is 6800 and it has ZERO % silver. Because both rods have "silver"in the name I think that's where the confusion comes from. I did not name the rods. Thanks for watching!
Hello Mr. Brodie, as you are very knowledgeable about soldering, I have a question.
I have a motorcycle frame from the Harris company in England. This was soldered with SIF Bronze 101.
Which gases do I need to re-solder one or two solder joints!
Oxygen and ...?
thank you for the information
greeting
Karsten
Hello Karsten. I am more knowledgeable about brazing than soldering. I would use oxy-acetylene.
You should never stand in front of the regulator like he did while opening it. If the reg fails it'll shoot the valve out like a 30_06
thanks teach
Excelente lección; gracias, es usted un gran MAESTRO!!!!!
