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.🤓🏁

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 KZfaq for us, garage learners.

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 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!!!

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.

@paulbrodie Жыл бұрын

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.

@andrebartels1690 Жыл бұрын

@@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 🤷‍♂️

I believe the purpose of the flux is to stop the steel oxidising which would prevent the bronze from wetting. So the important conclusion from the icicle experiment is the poor join to the steel base. Also be careful with flux - boron causes infertility! Thanks Paul, love your videos.

I believe the flux has 2 purposes. The first is to "help prevent" the steel from getting too hot, and so allow the bronze to adhere. Too much heat will cook the flux, but it does help. The second is to help the bronze (or whatever filler rod..) to flow. Don't worry, I'm too old to have kids.

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...

Gloves… I’m retired military and retired Firefighter so I have multiple types of gloves to choose from. My favorite for welding etc are my nomex flight gloves. 99% dexterity and good heat protection….. NOT for up close high heat but I don’t put my hands in fire too often but I have even better firefighter gloves than the bulky leather gloves with no dexterity…

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!

Great instructional video. Not a wasted word. Thank you. How do you usually remove the flux after nickel-silver brazing?

@paulbrodie 3 жыл бұрын

Easiest way to remove flux is by running it under hot water. Thanks for watching!

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.

@paulbrodie 3 жыл бұрын

Well, the heat brick isn't taking up that much heat... but it's great that you were looking for a solution :)

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

Hi Paul! Thank you so much for your great videos! I really appreciate your effort. I am wondering if you could give me some more information on the flux paste that you paint on in the tube to plate demo? I currently use stay silv white in the little bottle with a brush cap. It is so much thicker looking than what you are using. And mine drys out really fast. Any tips would be greatly appreciated 🙏🏻

Thanks for liking our videos. We have made two brazing videos. The second one shows all the rods and fluxes. I think the information you want is right there.

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.

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?

Would you be able to make a video on silver brazing a lug for bicycle frame building? I am working on that currently, but I struggle to pull the silver braze from one end through to the other end, and I usually end up overheating the metal.

@paulbrodie Жыл бұрын

I won't be making that video, but there is one out there. I think a part of the title is "silver brazing". Sorry I can't direct you better than that. It is worth searching for. It's about 20-25 minutes long, and the filming is very clear and easy to see what is happening with the heat, flux, etc. I could not do better. Good luck in your search.

I first tried oxy acetylene welding and brazing in high school. Your videos have been very helpful, Thank You. I'll never forget a British motorcycle frame that was clear coated over the bare steel to showcase the fillet brazing. From 1/8 in. to 1/2 in. wide, perfect, evenly spaced ripples. When I tried to duplicate this, my appreciation of the craftsmanship was humbling. I mentioned this to a friend who is far more knowledgeable who said that was done with Sifbronze. Have you ever heard of this? Also, your shop and your methods are an inspiration, Thank You for sharing. After watching some of your other videos I find that we are kindred spirits. I too own a H-D Sprint.

@paulbrodie 3 жыл бұрын

Hi Don, Thanks for liking our videos, and that's great you own a Sprint! Model? The brazing style you are referring to has been called "a stack of dimes". That is definitely hard to do, perhaps it was Sifbronze, but perhaps it was Tig-brazing. I think for me it would be easier with Tig. I will check it out...
