Soldering is not a strong mechanical bond. Just a surface bond. It Melts at temperatures below 200F. It cracks under force, heat cycles or vibration and therefore needs strain relief to prevent joint failure. Usually only copper to copper joints in plumbing or electrical connections. Brazing is much stronger, enough that it can be structural. Is done at much higher temperature and can join several metals even dissimilar ones with a strong joint often as strong as welding. So, no. They’re not essentially the same.
I like the longer videos. You aren't asking for 15 minutes of our time, you're granting us 15 minutes of yours. Now admittedly I'm not in your average viewer but I'm certainly happy when I see a longer video anyway.
It's a terrible joke. When you are really dirty and you take a bath, you can leave a ring of grime around the tub. The first one in is the leader, hence "ring-leader".
Also, since there are multiple people in the tub, obviously somebody had to come up with the idea and convince the others to bathe with him. Thus, double-entendre.
Matthew Montgomery. Yup. And if it were a given that the audience would understand the idea of sharing baths, this really dates the book. Do we have to rename the channel 'this archaic Tony'?
Older cast iron bathtubs had a tendency to be cold around the edges and back in our day it was common (because it was so much work to heat up water on a wood stove) to not throw out the water from the first bather but simply heat it up with an extra pan of water. After a few bathers (normally kids in a family) there would be a waxy/greasy ring around the edge of the tub. Based on that, it’s amusing at best an appropriate for a 7 year old joke book from the early 30’s.
Yep my mom told me stories of half a dozen kids taking baths in the same water, and the younger kids had to go last as they were presumed to be more likely to pee in the tub.
The blue is surface impurities trapped by the flux from the cobalt matrix of the insert. You made Smalt, Cobalt Alumilite, where we get the famous Cobalt Blue.
Cobalt Glass! ?! Makes sense, if the "cemented" carbides are cemented with cobalt. Then you get cobalt oxides, which dissolve in the flux along with the other oxides, making your own custom bits of glass!
I remember those books! One of my favorite books was called "The Boy Electrician," or something like that. It was published in the 1940s and still in our library and contained safe and sane things you could do at home, like getting ahold of an old x-ray tube, building a high-voltage power supply, and using it to make radiographs of your hand, your sister, or whatever. It was probably that book that finally convinced me the grownups really were out to kill us. Well, that and the A. C. Gilbert Home Atomic Energy Lab, that contained a spinthariscope, a cloud chamber, maybe a Geiger counter, and, of course, samples of radioactive materials to make it all work.
It must have fallen off the table... The one that has his vise mounted on... He might keep his "stick" in it and could get stuck... With a stuck "stick", how can you reach the top drawer? I mean not everyone is blessed with a large vise ...
He seems to be, this isn't the first time...and he's talking about short videos. He's coo-coo. 3 fries short of a full meal, 9 horses behind the ring leader, one chip besides the shoulder...
My favorite part is him taking the time to specifically explain to us that brazing is not welding and then proceeds to refer to it as welding several times. Our minds are funny that way. Great video.
You are solidly in the #1 spot in my que. I had one teacher, once, during my formative years, that was able to deliver useful information with high-quality humor. This burned the info into my head and I still remember that Masvingo is the capitol of Zimbabwe. I LOVE Diresta, AvE, Tips from a Shipwright, Abom79, SV Seeker, Clickspring, etc., but you are #1 in my (current) book. Thanks a ton.
Not necessarily, in the country of Zimbabwe both the Province and Capital are Masvingo (province). So it's the capital of the province of the country? Confusing because there is just a town Masvingo as well, not Masvingo Province. OK I'm sleepy now
I really enjoy (and learn from) your videos. But as a metallurgist, I have a few comments. "Soft solders" include the 96Tin-4Silver replacement for various Tin-Lead alloys. These alloys lack sufficient shear strength for tooling applications. "Hard solders" are brazing alloys, defined by the American Welding Society defines as having liquidus (flow) temperatures over 840F. Silvaloy 450, Safety-Silv 45 and other BAg-5 alloys are 45Ag-30Cu-25Zn and flow at ~1330F, plenty hot enough to soften high speed steels. When building carbide tipped tools with large surface area or corner/slot constraint, consider one of the trimetal shim preforms available from Lucas-Milhaupt. Silver-copper-silver (1-2-1)composites manage thermal stresses better and avoid carbide cracking. Obviously, the filler material and flux are in place before the torch is lit. Also, joint clearance is important. For the BAg-5 alloy, 0.003" per side is optimal and provides highest joint strength.
My dad was a career welder but he wasn't super great at explaining it to his spaz of a son. Thanks for going into detailed differences between silver soldering and silver brazing -- probably saved me a year in therapy right there.
can I just say. I'm going to school for mechanical engineering and I'm one year from graduation. Before this video I had no idea what the application of braising was. Thank you for putting the time in to teach guys like me, It has made me a way better designer and all around engineer. love this channel!
I am late to this one but wanted to say that this was one of the most straight forward explanations of what Flux does when soldering I have come across. Thanks!
I work in band instrument repair. I fell down the rabbit hole of your channel because we do a lot of lathe work to make our own tools. Brass instruments are held together with solder, so we do a lot of that as well. My experience has mostly been with 94/6 and 96/4 tin/silver solder for what we call "soft" soldering. Something that we want to be able to take apart again some day. We tend to use the terms "hard soldering" "silver soldering" and "brazing" interchangeably, even though our soft solder is technically also a silver alloy. Silver soldering is for things we don't want to come apart again ever (broken parts or homemade tools, usually). It's interesting to learn more about soldering applications that I can bring to the shop. My friends and I love your content and humor. Keep it up! (:
So coming back to this later and not sleep deprived, a good tip is to clamp the high speed steel into copper or aluminum blocks to help absorb the heat at the cutting edges which can be good if you really want to weld hot.
It’s interesting to read all the “ringleader” joke theories posed here, and they’re likely proof of why people fail to understand the actions of their predecessors in history. For all the clever suggestions, the joke is certainly simple, was utterly obvious at the time, and would have been funny then. In an age when most of the population was rural, electricity and gas weren’t yet universal and were often quite rare, and therefore heating water was difficult and expensive, entire families shared bath water, which probably also had to be drawn by bucket from a well or hauled from a creek. People worked farms and “dirty jobs” industries, in the heat, got really dirty, and in many cases bathed only weekly. Where you might eventually make a dirt ring at the waterline today, the ring was “quick & dirty” then, pun intended-grime, oils, soap. So the first person in the tub, perhaps the head of household, was definitely the ringleader. Everyone used the word in its usual senses, so the pun was obvious. It’s been said that after a family of 10 finished bathing in the same water on a Saturday night, the water was opaque with dirt. Since children often bathed last, finishing with the youngest, the saying arose, “Don’t throw out the baby with the bath water.” Its meaning is philosophical now, but then it was a joke that referred to the fact that the baby was practically invisible in the filthy water. Sounds disgusting, but after a week without any bath...maybe not. Many more people were poorly educated. A seventh-grade formal education wasn’t uncommon a century ago. Life necessitated work, not more school, but while they were behind us in formal education, they were often ahead in practical skills. Nonetheless, times were simpler and so was humor, so the ringleader joke would have been a lot funnier. It’s enlightening to hear old Vaudeville routines from those days. Their uproariously funny humor is beyond corny now, yet there’s a lot to be said for it in contrast to today’s comedy. As for modern interpretation of the ringleader joke, it’s easy to make the same errors people easily make when looking at any historical item. If you don’t know its context, you’ll inevitably judge it (distort it) by modern expectations, analyze aspects into it that never existed, subject it to your own biases, and reach a faulty conclusion. You have to be careful and thoughtful with the past. In some cases, people have forgotten that.
Thanks for that. I grew up on a dairy farm, and vaguely recall hearing this joke as a kid. Honestly, it probably fell as flat to me then as it did to me now, and had to be explained then as well. Your explanation seems correct. Matter of fact, the "dirt ring" was the thing that immediately popped into my head when I heard this joke for the first time, again(?). Indeed, the humor is probably lost without proper cultural and historical context. It was probably only because of my rural upbringing that I even managed to connect the dots to make this joke make sense. To most of the populace nowadays, even explaining the that it's a "dirt ring" would have left blank stares as taking a bath is far less common, much less sharing the same bathwater. Bathing. Reminds me of ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dPmBle0Dljw.html
Did you just come here to tell us how stupid us "muricans" are? I suppose you consider This Old Tony is in the same boat for simply posing the light-hearted question. What a miserable human being you must be, either delighting in the trolling of perfect strangers, or casting aspersions on others' intelligence simply because your cultural history differs from theirs. Perhaps both. Regardless, neither speaks well of your own intelligence or ability to see things from others' perspectives. Maybe if you use a few more swear words, you'll sound more intelligent and win people over to your argument.
Don't you ever dare apologizing for chit-chatting and long videos. I would never complain if the videos had more chit-chatting and were longer. They're good now too, matter fact, everything you upload is good. Keep it up!
In German brazing is „Hartlöten“ and the other is „weichlöten“ „Weichlöten“ goes to 450 „Hartlöten“ goes to 1200 „Schweißen“ is all over 1200 Measurement is in Celsius Good day together
> Good day together German confirmed! (Guten Tag zusammen) In English you don't use "zusammen" to refer to the people present. It's more normal to say "all" or "everybody".
You need to also take into account that Baths were universal and showers weren't a thing until fairly recent. Like 1950's, so the "ring" would have been far more common knowledge.
According to the AWS, soldering uses a filler material that melts below 450° C; anything with a higher melting point is considered brazing (short of welding, of course).
I learned to braze when I was 12 years old. My Pop had a nice torch which used propane and compressed air. Lots of fun and functional too! Great video, thumbs up.
Okay, I have to make a confession: I have used Oxy-Acetylene to solder copper pipes. You have to be really gentle, though. I tried to show someone else how to do it -- he said he knew how to braze, so I assumed he could also solder. I looked away, and when I looked back the entire joint was glowing. He actually managed to fuse the copper joint together. Goes to show, don't assume that people know what you mean.
Your videos are always a highlight of my day/week/month regardless of length! Just want to say thanks for what you put in to them because I love every second of them. Always brightens the day.
Bathtub ring. All three are bathing and the first guy is pegged as the starting point of all three creating a bathtub ring. I am a life member already, thanks.
Long videos are awesome. I love long youtube videos from any/all of my favorite creators because it means that there's a lot of content that they put time and knowledge into and I learn so much from the longer videos. It also works out when I can sit down with one video on my lunch break, rather than flipping through four or five, to fill the time.
I had a "Puffin Joke Book" when about 7 yrs old (43 yrs ago) and can only remember one joke from it to this day: I'd tell you about the shark infested custard, but you'd never swallow it.
I like how Scott from Essential Craftsman put it. He will make the video however long it needs to be to effectively convey the information that he needs to convey. If the topic takes 2 minutes to convey, the video will be 2 minutes. If the topic takes 40 minutes to convey, the video will be 40 minutes
You are positively, oh so, on the wrong track if you are concerned with "too long"...From a gearheads perspective as well as, and equally as important the humoristic angle, I can't ever get enough.
I was tool repairman for 3 years at a very large tooling company (I believe 26 worldwide locations?) My daily work load consisted of removing old, worn out guide pads and cutting inserts from tools, cleaning out the pockets, then cutting new carbide pieces or using precut PCD (diamond) cutting inserts and brazed them into the pockets before I sent them off to our wire EDM department, where they would cut the PCD inserts into shape. Our reamers had guide pads, which would precisely guide the tool through the bore that the cutting insert just created, and they would be ground within 3 microns. Whole shop had to be temperature controlled for accuracy on the machines. It was a fun job for a while, but now I never want to braze anything for as long as i live, lol. They paid me extremely well for doing it though.
Tony, I love your vids, but this has got to be the best vid I have seen on silver brazing. You completely demystified the flux and filler material. Thanks
Don't take this as a insult. I totally watch all your videos for their content. However your chill attitude and relaxed canter help me unwind and go to sleep. Thanks for the amazing videos. Seriously
Great video Tony as always! Mapp gas and a turbo torch would do the joints you did with no problem. anything bigger your right you need the oxy-acetylene. High speed steel brazes fine with safety-silv 56 which has a liquidus of 1205F which is in the realm of the red hardness range of high speed steel. The safety-silv 45 has a liquidus of 1370F so it would not be ideal. I only buy the 56 because it works better on just about everything. ATB, Robin
Appreciate the cameo from Alex French Guy Cooking. He sent me here. *gasp* I would never have found you without Alex. We have so much to thank him for...
Just found your site. That break away to fart make me bust a gut! Its nice to have a guy teach things without swearing as well. Now I have another channel that I can safely watch around my kids.
Brazing, contrary to old timer assumptions, is not mechanical there actually is chemical fusion although the base parts aren't melted the atoms near the surface do diffuse and alloy. I think the term brazing actually [originally] referred specifically to hard soldering with brass and bronze, current common use is just a synonym for all hard or high temp soldering. Metallurgically speaking fusion welding also doesn't need more than an atom or two of penetration to achieve full strength, the hitch is in practically accomplishing that such precise fusion in a real world joint without significant flaws.
Excellent discription, yes, brazing temperatures does alloy with parent material, soldering does not. I am not sure in the regard to the sintered carbide, does it alloy, or does it penetrate the sintered structure. May I ask your opinion on this. Regards John.
Tony, I hardly know anything about all of the wonderful things you talk about, honestly, but there's just a certain kind of enjoyment in watching your videos that is unbeaten by anyone else, thank you, this is just too pleasing.
As someone who lived in an old country farmhouse and took baths in a big galvanized steel tub with water heated by cook stove, I can confirm that when multiple people take baths where you use the same water, there is a visible dirt ring left after the first person bathes which gets more pronounced as subsequent people take their baths... Is that simple. I already have a lifetime subscription to the channel so having my initials: RKP stamped under a handmade tool data plate will be reward enough.
Reminds me of the bathtub joke on Sesame Street: Bert: “Ernie, why do you call the bathtub Rosie?” Ernie: “Well Bert, every time I have a bath, I leave a ring around Rosie” It’s jokes like these that left me isolated and alone as a child.
"I call it, saving money by switching to Geico ..." was the answer in the first sentence in the commercial that came in right behind your question. LOL!
Ringleader kids joke from long ago, enamel coated tubs are awful for getting rings of dirt and soap scum at the waterline. Bathtub rings were the main selling point for bathtub cleaners, thus the first person in the tub would be the ringleader. And thank you for your videos.
Ring around the tub (the filth left at the top of the water when one takes a bath) so the first person in the tub would be the leader of the ring of filth, or the ringleader (also the conductor of a circus) first person again. Running the show, making the joke work on several planes. Great videos. Keep them long, it works.
Coincidentally, for me anyways, I just read a few days ago that the “mapp” gas in little yellow tanks isn’t true mapp gas of olden days but just a marketing name now. It’s temp is similar to propane. Environmental laws outlawed the good stuff.
Technically, it wasn't environmental laws. The components of true MAPP gas were originally essentially waste products, but then became valuable as feedstock for the plastics industry. Businesses being out there to make a profit, they stopped selling MAPP, and sold the gas to the plastics industry instead for a higher profit.
Hugh Jafro old news, MAPP hasn't been made in North America for years now, funny how they take propane add a couple additives and make you think it's real MAPP
If there is a better RU-vid videographer out there, please let me know. I spend most of my life here learning, laughing and loving everything I see and hear. I now know exactly what I cannot do. I know what I want to learn to do, and what I need to sell the house to afford to buy. When I am finished, This Old Tony will be the Dearly Departed Tony. God forbid. Geez, Heaven is gunna need a bigger workshop.
The first thing I look at when seeing one of your videos is the timeline to see how long it is....anything less than 20mins and I am ever so slightly disappointed, but nonetheless still very happy to see one of your productions! Great video Tony, although I am still wondering what 'soddering' is....(I am British..) Thank you!
It appears that in the American language, any use of the letter L after an O gets dropped.... I watch another youtube channel of some guy in new york fixing laptops, and the amount of soddering he does is amazing....
Never mind sawdering, our great American cousins have started to pisspronounce Height incorrectly, listen closely and a good number say HEITH, drives me mad.
Yes, the tungsten carbide is crystals in a cobalt matrix, a bit like carbon in steel. The cobalt forms oxides on the surface, and these are dissolved into the molten flux, forming a bluish glas.The green colour on the stainless shaft may be the nickel, iron and/ or chromium oxides also dissolving into the flux.
Small correction, carbon steel isn't carbon crystals in an iron matrix. The carbon is fully dissolved and thus part of the iron crystal lattice. Over 0.8% carbon(the eutectoid point) some of the carbon will combine with iron to create iron-carbide aka cementite which is separate particles in a steel matrix. In alloy steels tungstain, vanadium, and chromium are all strongly carbide forming alloys. (and why Cr must be over about 12% dependent on carbon content, before enough free metallic Cr is available to make stainless steel ) The border between steel and "iron" [in the blacksmith material sense] is that in steel all of the carbon can dissolve into the crystal structure (at the appropriate temperature) when allowed to reach chemical equilibrium, this has a maximum of about 2.0% carbon. (a few exotic alloys with lots of carbide formers can go a bit higher) Cast iron has about 4-5% carbon(the eutectic point) and so forms graphite particles that make grey cast iron grey when fractured and easy to machine being self lubricating and nice-chip forming This high carbon makes tons of cementite in "white" or "chilled" cast iron making it extremely abrasion resistant. (Molds are cooled and made with heat conductive materials to quench straight from the molten stage, this is not allowing chemical equilibrium.) White cast can formed on just one portion of a cast as well kind of like a case hardening, or it can then be heat treated further to convert the cabides back to carbon and make ductile or nodular cast iron. (I forget which one is made from white as I get the two mixed up. Nodular for sure has rounded nodules of graphite making it a bit more ductile than grey.)
The first person in the bath creates the dirty ring around the water line, as others hop in, the water goes up, but the first guy was the ring leader. he started it. Love your show btw.
Big tip for anyone trying this...that soft sil solder that comes in a roll will boil, and pop in your face if you overheat it. Wear some sort of eye protection. Also, if you're new to brazing, the flux tells you when to add the solder. Once it liquifies start trying to add the solder. If you get it burning red hot, you'll burn the flux off, and your braze joint will not be as strong as it could of been. That's if you could even get the solder to stick.
That Oatley stuff isn't silver solder. It's lead-free soft solder, mostly tin with a frisson of Ag to lower the melting point. Your silver blazing wire is silver solder, exactly what a jeweler would use.
It's absolutely still silver solder, just not the silver solder you're thinking of. There's a world of difference between what the jewellery, plumbing, and electronics industries consider "silver solder" to be. None of them would want to use the stuff from one of the others.
James Churchill No, there's no application where someone could specify silver solder where that Oately stuff would be acceptable. HVAC silver solder is at least 15% Ag, higher for joining dissimilar metals. That Oately stuff is lead-free soft solder for potable water connections. Usual composition is about 97-98% tin and 2% silver.
I said nothing about where they were applicable, I commented *only* on the industry-specific nature of the nomenclature. So I don't know what you're trying to argue against.
Aircraft mechanic here. I don't think I've ever encountered brazing in aircraft structure. AFAIK, old tube and rag ships like the Cub are welded chro-moly. Aluminum semi-monocoque hulls are made from 2024-T3, so welding or brazing would kill the heat treatment of the metal (and the crew and passengers), so those structures are riveted. Aircraft are increasingly made of composite materials, which behave even worse than aluminum when they encounter a torch. Brazing happens every now and again in the power plant, some hydraulic fittings get silver soldered. BTW, though they do teach a couple weeks of welding during mechanic school, it's mostly to impress on A&Ps that you should NEVER under ANY circumstances take a welding torch to an aircraft, you get a certified welder to do it. From what they taught me I think I could repair a broken shovel or wheelbarrow with an oxy-acetylene torch, but I wouldn't trust myself to do any welding on an aircraft.
Jeeby creeby Ton the profanity has been off the charts in this and the last vid. You said BUM. Frankly, i'm appalled. What next, gentleman sausage in worktop clamping equipment?!
I've been puzzling over this joke for 2 years now, and I think I finally have it. It doesn't make sense, because you left out the punch line: "How should I know? I'm not Catholic!" You're welc
I used to build chillers. We called it silver solder and soft solder. We “silver soldered” (brazed) any shiny metal parts, such as stainless heat exchangers. We “soft soldered” (standard torch) all copper water piping. And for copper refrigerant piping we brazed it using some kind of stick. Can’t remember what the stick was, but we just called it brazing copper. Brazed, silver soldered or soft soldered. Hope that clears this up😂
The black flux you used is high-temperature flux, it resists burning out of the joint under prolonged heating. At the same time, it's not as chemically active as white flux formulations. White fluxes turn to clear liquid when the part comes up to brazing temperature announcing the joints readiness to be fed filler. What the flux is doing is not just preventing oxidation of the joint, but actively scavenging flecks of oxides left in the joint. You might try heating below the insert next time to bring the shank up to temperature, then applying the heat to the insert. It also works to insert a preformed piece of brazing filler metal into the joint beforehand, and let in melt in place. The void under the insert would have been a good location to insert a preformed piece.
