My left ear enjoyed this
hahahaha indeed!!!
Well at least now that you recognize the problem you should easily be able to fix it by putting your audio settings into mono the both of us can get excited.
LoL. Did it make a difference
Haha 😂
If you are using this flux remember that it can be quite corrosive. Stainless steel gets it's corrosion resistance from forming a very thin coating of oxides on it's surface that protect the metal underneath. This process is called passivation. Soldering stainless requires a strong acid flux to depassivate the surface. Using an abrasive also helps. After using the flux the joint must be cleaned thoroughly then repassivated. I use a solution of baking soda in water to do this. The result is 50 year old solder joints that are still solid.
most flux are actually corrosive some are just not as much corrosive than others, rubbing alcohol and baking soda with water are a good solution to neutralize the acid
Excellent video Robert Murray-Smith!
Straight and right to the point with zero excessive babbling.
Yeah, couldn't hear the first two ingredients.
can the same aluminium rods used for arc welding be used for butane torch brazing? i have flux cored but its not really happening , is having seperate flux and filler rod better for my purpose?
Here's a question for you. Where can we find information about the different salts/acids that are good for fluxes? Phosphorous seems to assist copper in melting but what if I want to also incorporate the 'cleaning' aspect as well. I want to simply braze stainless steel and while there are countless fluxes I can buy (and the brazing rod has P already in it) apart from this recipe which seems to be suited to Sn/Sb/Pb but I want something that's better for melting and bonding copper to Stainless. What resources can I reference to help me learn this bit of inorganic chemistry?
hi rob regarding silver brazing applications
can i use your formula for both
high silver alloys (35 to 50 percent silver) for ferrous metals and low silver alloys (5 to 7 percent silver) for copper base metals.
Sir i need dip soldering rosin liquid flux formula for electronic board
So hey... TY for the VID. But I'm wondering.... Boric Acid mixed with denatured alcohol is a common recipe found online and in use everywhere... what benefit does adding all the extra ingredients (namely TSP and Borax) offer?
Hi Mr.smith.Thanks for your great video which i found very useful. Im trying to make aluminum flux.With a quick searching found out that it is made of potassium silicofluoride(K2SiF6) or potassium aluminofluoride (K2ALF6) with extra addition of ZnO or ZnF. if you have any information about how to make something like NOCOLOK Flux, i would be very thankful as you guide me a little bit.
Can we replace trisodium phosphate with di potassium phosphate ?
Thanks for posting
Will this mixture work for brazing aluminum?
As ever you rock Robert! thanks again :-)
That's great I was googling how to do this and of course you have a video of it fantastic
Teaspoon? More like all the tea in China spoon.
ILl be honest. this hasnt worked for me. I used the same ratio, made a syrupy flux. Put some on some bolts I have that I was to solder to, and instead of soldering anything. the flux just puffs up into a crystallised thing and nothing solders :/
Is this only good for flame welding?
this is for brazing useing a pressurized flame ,with brazing rods with little to no tin and zinc added .not for soldering with a iron which cannot consistently saturate the work area with heats the are required to melt the flux ingredients ontop the area to be welded . soldering uses liquid low temperature flux to keep the area oxidation free till the solder cools down.
if you do mean brazing but just mixed up words then i would suggest if possible picking the parts to be welded to clean them from the protective layer added to metals like copper . or sand it good ..
but this method does work as long as the part remains free off oxidation till cool down
hey rob, I've had some success making soldering flux from pine resin, don't know if it works as well as the boric acid route but it's easy to get and smells good, well worth checking out if you run out of chemicals
I used this for. Years and it works a ok
i am looking for water soluble roller tinning flux used in printed circuit board formulation
Seem there's a lot of variation in in people's formulations.
So, why the TSP?
Help me to create a solution that can sold gold jewelery.....what rasio of borex and others ingredients
can you tell me in comments what 3 things is added to make this i am not getting you in video
Coated silver brazing rod
What is the coat made from ?
and hnks
It's fun to search Google for information only to find that you've already subscribed to the source of information on UA-cam. You would make an excellent neighbor. Cheers!
lol - cheers mate
I think finding flux is more easier than finding any of this 3 ingredients.
:o)
TRUE
All three are dirt cheap and easy to find in the US, however they may be more difficult to source elsewhere or perhaps go by other synonyms.
Boric acid is sold as cockroach pesticide, borax is sold in every grocery store as a laundry detergent, tsp is sold in the paint isle of every big box or hardware store.
All you need to find is some petroleum jelly it works just as good as any good quality flux
I agree with you:-))
I LOVE THIS THANK YOU FOR SHARING YOUR KNOWLEDGE!!!
Yeah super easy!!!! Let me go to my pantry and look for the ingredients...
this is also for brazing too?
so you found a bunch of exotic chemicals but could not find some flux paste? lol anyways i have BA but idk what borax is or if its the same familly,also the tri sodium phosphate ,do you really need these other two? i was having trouble trying to solder 1/16" steel wires for fun exp to see if i can do it with a mini torch i juts made that uses oxy and propane,,so i tried silver soldering with some regular flux i found and i was having problems,,i figured it might have been the heat was too high so i dialed my flame back but it was still oxidizing and the silver just exploding or balling up,after some online search i figured let me mix some water with boric acid pest killer i have ,and it worked beautifully,simply applied the paste between the two rods (which helps keep em stuck together) and then slowly heated them till cherry red and started applying the silver and it was melting nicely and coated both rods ,,love it ,juts made this now
Man this guy is a legend 👑 I have learned so much from this man. We need more people like him in the world. I hope one day to be a man of such knowledge and share it with generations to come
funny thing is- I have those things laying around... Tricleanium for cleaning prior to painting (like sugar-soap) , borax from the laundry and boric acid from a termite treatment.
Which flux ? for which application ?
rather difficult to hear the names of materials needed sir (bore acid, phospate, borax), can you help me to write down here please ?
I heard: Boric Acid, Trisodium phosphate and Borax. In a mix ratio of 3:2:2 spoons along with 100ml of water and heat (medium?) until your desired consistency.
boric acid
trisodium phosphate
borax
Hi friend,
I was thinking about your copper ink video. Do you think that with those chemicals mixed with your ink, you could fuse the copper with a torch? (The support may be glass or ceramic fiber in order to sustain the temperature.)
hfyaer I don't know - it's worth a try
Wow now that's interesting
Or a Bunsen burner or a propane bottle hey do you think I could use aloe vera gel as a flux or what's in it that makes it super hot. Are we just going after the gelled type thing here
Can you please tell me what are the Ingredient for making Flux which i can mold into Cone shape or Flux Paste.
boric acid
trisodium phosphate
borax
can you help me with the recipe of aluminium brazing flux?
Hi there,
In Australia, I can only seem to easily find a product call 'Tricleanium'. It's ingredient is trisodium phosphate dodecahydrate. Is this suitable to use as the TSP ingredient in my flux?
i am sorry mate - i don't know
Trisodium phosphate - TSP - WE nr. 231-509-8 CAS nr. 7601-54-9 (Na3PO4) look for a chemistry shop or check on your national auctions website (like ebay...)
How do you make flux for electrodes
That's good stuff. I remember I used to use as flux for tin over s.s. only phosphoric acid on a very clean surfaces. Have you tried that?
timbear3 no i haven't - i'll give it a go
Just need to get the Water. THANKS! Cheers ~ *
Thanks so much
I was wondering what would be the most useful chemicals for the home expirimenter to have on hand.
We all don't have a full chemistry lab at our disposal.
PETER MOLL It depends on what area you want to work in - there are a few basic reagents you need often like a range of solvents, acids and alkalis but it really is a matter of what you are interested in - the only reason i have a full chem stock is because when i want to demonstrate something i buy a lot of the chemical - like a kilo or so and then leave it in the stock cupboard so when it crops up again i have it. The area I work in means i have a lot of binders, solvents, acids and metal halides - but you will build up a stock of what is useful to you just by buying what you need when you need it
If you can't find Flux at home, it's easy to make your own. For this you will need 500 grams of plutonium, 200 grams of platinum if possible from a meteorite spat in Egypt less than 2 years ago and a can of Boeing 737 kerosene brought to a temperature of 1 degree below boiling point ^^.
All joking aside, thank you for this tutorial.
You're a champ, Man. Will using distilled water screw with the compound? I, unfortunately, don't have deionized water available.
nah - same thing basically
Thanks for answer! Distilled=Deionized....nice!
thank you sir
Hi, as my english is not good, you said Bore acid, phosphate of sodium, and borax? thank you in advance.
boric acid
trisodium phosphate
borax
Got the other materials ok but having trouble getting water.
That's amazing. How long can you store it?
Can the quantities be written?
would this be suitable for melting aluminum (aluminium) copper and bronze?
+George Wood it's just a borax flux mate
To melt copper and bronze, you just need to add some borax powder, that's all. This flux is for brazing and soldering purposes. Aluminium melts easily without any kind of flux, but problems might happen when it comes to soldering it with a torch. You'll need a special kind of solder, and a special kind of flux. This one will not work for soldering aluminium.
Thanks!
Hi Mr. I AM brazilian and i do no speak englishh and i no hear . i ask what the third component acid boric' bórax and?????tthanks thanks thanks
Trisodium phosphate (tsp), it is a cleaning product found in the paint department in most US stores at least. There is also tsp substitutes which can be misleadingly labeled and will *not* work for this purpose. The ratio is 3:2:2 (boric acid:trisodium phosphate:borax). Also keep in mind this is an acidic flux which can be undesirable.
A borax az hő álló vagy nem ?
Gonna give that a try. Have everything except the borax, but will buy some. Thanks :-)
Hi.. Great video. .. how to make flux for Aluminum
Can you use this for pcb solder/de-solder flux?
Since it's acidic, it can't be used for electrical connections. The flux will corrode the copper over time, producing an insulative 'cold solder joint'. For pcbs, you have to use rosin flux.
That is exactly what I have been trying to find. Home made and cheap as dirt. Thank you!!!!
glad i could help - cheers mate
are you on that “thats my dog “ viral video doing the new version of the chacha slide?
That's a huge teaspoon you got there ;)
(I know, it's all about ratios so it doesn't matter but I just thought it was funny to see you use a tablespoon and talk about teaspoons)
fair enough
He's in England; evidently that's the spoon for tea. :-)
Ni5ei can u plz guide me how to prepair soldering flux & chemicals name & ratio
I thought for a second there, you were doing a remake of "The Birds!" lol
Eflat Productions lol
Great video!
In your video editing software, there should be an option to remove sharp sounds. When watching this video with headphones, the noise from the plastic bags, & clinks from the glassware become very sharp.
shut-----up
flux for aluminium?
Can I use distilled water, I can't find the water u describe
+Craig Ellis no worries
ive heard that you can use tree resin ive never tried it but what are your thoughts on that?
сталкер чворович you definately can - well rosin - which you can just buy as a powder
сталкер чворович If you can't find it, you can get rosin from a music store, they use it for the violin stick, you crush a piece and dissolve with isopropyl alcohol but that rosin can be expensive, you may buy rosin chunks from a local market too, most probably cheaper. They get different and confusing names.
Robert Murray-Smith thank you mate
zerpBot thanx
zerpBot they also use it on dance studio flooring too for grip while dancing apparently, saw loads of it when I was at one helping someone clean up after classes.
this is not "ROSIN" flux is it? can i do electronics work with it. i think what your doing is welding?
I am not understand or heard your voice not clear kindly , reply me about ,boric acid +borax+ what is 3rd , am thankful you
boric acid
trisodium phosphate
borax
Can you write that list of the 3 items. The audio isn’t that clear. Also I’m new to your accent.
Can you make a no clean flux for pcb soldering.😁 Just like those amtech no clean fluxes.. please, please, please...😁
You know if you turn your 5L can and pour it side ways its much easier
sounds like the trisodium phosphate is the hardest of those three things to get since they are pulling anything with phosphorus in it off the shelves here, I had to use a cola (has phosphoric acid) to color anodize some titanium ages ago cause they sold nothing at a store here locally that had phosphorus in it including the TSP (all they had was TSP substitute free of phosphorus of course lol)
wonder how hard it would be to make TSP out of mono calcium phosphate fertilizer and say some drain cleaner (*sodium hydroxide) from what I am reading the monocalcium (*triple strength phosphorus fertilizer) can be turned into phosphoric acid effectively by adding sulfuric acid to it and the acid and calcium react to make calcium sulfate which is supposed to be insoluble in water, so it separates out with nothing more than a fitration (if so) so I guess once you have phosphoric acid that could be added to the sodium hydroxide to get a sodium phosphate compound, just not sure what conditions to make sure it becomes TSP are required lol.
Thomas Anderson TSP is pretty easy to buy mate - home depot sell it in bags - i got mine from ebay
I tried home despot here and they hardly sell anything it seems though I have not tried for TSP yet, will have to have a look at that for sure, everything else though like toluene and such they either had nothing or had some substitute like xylene instead only, most of the stuff I have found (which still excluded TSP) was at ace hardware. could just be the part of the country I am in but being in an oil state I would have figured they would be ignoring most of the "save the planet suggestions the rest of the country is following. either way I would definitely like to find out how to make it from other compounds, since the making is often the fun anyway lol
Thomas Anderson absolutely mate and you learn tons from synthesizing your own stuff
also I guess it got missed here, that I said hardest, lol not hard, with some diligence you can get anything even in the most politically restrictive environment ha ha
God one! Thanks!
Thank you for a simple flux that has worked great and easy to make Robert. Good day too. V
Hi, thanks for sharing your video, you could help me make flux to weld aluminum with autogenous welding.
Thanks and regards.
Is this good,? 3 ingredients
Silica Sand that AU was in
Backing Soda
BORAX
Interesting. The whole point to soldering flux is to keep metal from oxidizing when heated, right? Okay, may also to remove any oxidation there too, when the metal is heated. Soooo, wouldn't oil accomplish that? Has anybody actually tried soldering a joint immersed in oil?
Thank you for sharing your personality and knowledge with fellow inquisitive minds. The internet has gotten to be such a big place and over run by sales related websites, its often difficult to find useful information. Thank goodness for people like you putting it out there. Simple and with out a lot of fuss and bother.
No need to reply but if you feel like it, or if anyone else reading these comments has thoughts... I'm left wondering if there would be any advantage to using alcohol instead of water in this flux.
i know what you mean mate and i am afraid i don't know about using alsohol
Alcohol will be fine, but it might be tricky if you're using a brush to coat your flux. If you want to use alcohol, don't waste chemicals, just mix it with some borax and dip your piece into it. Then ignite the alcohol (take care not to ignite your flux dish ! if you do so, just cover it with a plate.). The flux should be evenly spread. But the flux on this video is better, because you can use it in a sprayer if you add more water to it. (I always use tap water to make this flux, and it works just fine.)
What's dionized water?
look it up - the answer is on google
Exactly.... If you have to buy all that, just buy the flux. Easier to find.
Yo this man will be making money on the streets if he had a Lab and straight up goons with him
How did the Romans make good swords? Did they use a natural flux?
Very nice job. Thanks for showing us. Also, are there any dangers with those chemicals, you know, eyes, hands, vapor dangers?
PS. Love your workshop and you seem to be right by the sea too. Perfect!
+Gort Newton we are right by the sea mate - for dangers re chemicals read the msds and handle appropriately - there is danger in a toothpick if you use it wrongly
what are the ingredients used to make liquid flux sir
in the video
sorry sir talk too soon i do not understand,can you write me thanks
click the "..." menu, then click "open transcript". Also in your account settings turn on auto-generate captions.
what is this flux for> SOLDERING FLUX? ?or what
You basically put in your @rse and soon after you'll sing like that seagull in the video....... :)
It's for melting nonferrous metals in furnances.
why dont sound
Yep... Just got this stuff layin around in my house somewhere
Is there anything else you might have to create flux? Yep, I'm a newb! 😊
DI water???? I just use borax and water to make a thick paste and done.
I enjoyed the chemistry lesson, and learned something as well! But your math needs some work. At the beginning of the video you told us that we need 3 ingredients, but you use 4. Do you not consider the water to be an ingredient? All in all, I still liked your tutorial, thanks!
it depends on how you look at it mate- in a strict sense you do -in a general sense who does? - but, i get the idea - cheers
Robert Murray-Smith so it's possible to make this flux *without* water?
i suppose - no real idea- give it a go
You should do a video on how to make toothpaste.
Goddam great video 😎😎🙏🙏👏👏👏👏🎉🎉🎉
No demo? Also, this is basically high temperature (silver) jewelry flux.
TheIdeanator see the video on soldering copper to stainless steel video for the demo
I use Zink cloride works perfect
interesting. does it work for hard brazing? or high temperature?
Thank u how about written recipe voice is not clear 🙋
ok mate - cheers
boric acid
trisodium phosphate
borax
Greetings from Kuffarland..... ;)
All you need is petroleum jelly it works just as good as any other Flux
yummy coooking
lol
And I'm so sorry if that came out very rude and disrespectful I don't mean to be I'm just trying to speak for the people that are little bit not as advanced in knowledge as you guys and thank you for letting me talk with you about this I am very thankful
Thanks for not waffling
Not working no soldering
Your voice is not clear... Please mention ingredients in discription or in reply which used in this video.
boric acid
trisodium phosphate
borax
is this your house
Good
