With respect, to aluminium braze you need to clean both surfaces and heat the material hot enough to melt the braze rod. You seem to be using the flame to melt the rod and that does not work.
Brazing Aluminium is tricky ,stainless steel brush or wheel is a must. both pieces being joined have to be 'metallurgically' clean. no contaminates , no oxides which is difficult to achieve as oxide will form on the surface immediately once you hit it with the torch. Sometimes , I will tin \ wet the surface and scrape the metals through the molten puddle.
Brush in stainless steel compulsory. Some alu from DIY stores contain lead to shine better but very difficult to solder. And heat the surface well, not the solder. You stick the solder, you don't weld.
I don't think it'll be enough fuel to make a difference what it will do though is when he takes turns it'll make the tire on the outside of the turn bite the ground better
*sees him try to braze Al, weeps slightly* If I ever need to deal with aluminum I TIG weld it for weld cleanliness if nothing else. That stuff is tricky enough without having to deal with the insane oxidizing power it has.

JohnnyQ90, You have to clean the aluminum really good with a stainless steel wire brush, then wipe it off with some acetone or lacquer thinner, then solder it immediately. Aluminum will oxidize very quickly and anything other than a stainless steel wire brush will contaminate the metal. Once you get it right that "aluminum solder" works great. Take care, be safe & healthy! P.S. The brass tank turned out great!
This is correct. Also if you would have made a small fold for the edge instead of butting them together, it would braised well. Not a fan of that myself, but it is very hard to tig a butt joint like that with such thin aluminum. Brass does look awesome
I agree with a half full tank almost all the weight will slam in to the outside corner and make understeer. Also weight moving left to right while you are going straight afterwards may make it a little squirrelly being in front of the axle. I couldnt have even come close to this fabrication much respect on your project. World needs all of this it can get right now.
Great skills dude. With the ali brazing rods, the material needs to be very clean and use the base material to melt the rod with no contact from the torch. Can't wait to see the finished product of this build.
Love the work. keep it up! I run a t-maxx 2.5 with 3.3 drive train. Engine/suspension. Wheelies all day. You give me motivation to keep going with RC's. Thanks for the vid's!
Glad to see you are still going, RUclips unsubbed me when I had notify all on (it did this for several of my favorite channels), so I was wondering where you had gone! Thanks for another great video, keep up the good work.
Hey I'm an oxyfuel welder and I do primarily aluminium you don't have enough heat in the base metal you need to wait to get what looks like molten lips and then shove in filler and move. It is difficult to learn but very effective to produce a vibrationally resistant and less stiff weld than tig. I know welding is not brazing the same but they do have similar principals. Hope this helped!
I think for the aluminium brazing you need flux. And what are your plans for fuel lines? You can use the brass ones like the ones on the exhaust and make them proper hard-line. :) Awesome build so far. Cant wait to see where the end will end up. hehehe
Hi Johnny, try printing with a brim or increase the initial layer height to .3mm in your slicer! This will insure that the part does not lift off the bed. Worked for me!
Great work. LiFePo4 batteries - good choice! However, try and avoid Copper Alloys being in contact with aluminum as they can cause corrosion problems due to their positions in the Galvanic scale
As someone has mentioned already but I'd like to add more info. When using those aluminum brazing rods you need to thoroughly heat the material first. You really wanna avoid heating the brazing material directly and heat the surrounding areas. Use the material to draw in the brazing rod not the flame. Basically how you dod with the second tank. You heated the material on the outside of the joint and let the material heat up the rod. Beautiful job on the second tank. I'd love to see a tig welder in your hands.
@Martin brazing is easy, and silver brazing can even be stronger than a weld given the right joint. What he needs to do is learn how to braze and not buy a gadget to do things for him.
From my understanding you shouldnt melt the rod with the torch. U need much more heat in the base material so the rod melts when in contact with the base material.
This thing is going to be wild. I wonder if someone could make you one of those flexible fuel cell style fuel tanks like they use in F1 and other racing cars.
Very well done! But you need a little hole in the Fuel cap, becaus when your Engine sucks in that fuel in your fuel tank will result a vacuum and your engine is running lean or starves because there will not run any more fuel. If you want to avoid fuel spouting out you can attach a little hose on top. But very good work so far. Maybe yout think about a Tig welder. I can recommend you the Stahlwerk WIG/TIG AC/DC 200 ST IGBT, its cheap compared to other inverters but ist welds very very good! And you finally can weld aluminium, brazz and other metals at a high quality. I bought one for myself before 3 weeks and i can highly recommend it.
John, all I can say is TIG welder, I practiced extensively (2 years) on AL awhile ago: but yes it does take practice-[the hardest practice to do are aluminum soda cans]...I used a Lincoln Electric 300 series, the big expensive one and pure Argon. Not sure if you got it hot enough, but has to be localized/small area and very hot (plasma) for short time. Gas torch is not very do-able.
Would be nice to see an alternator which should reduce the size of the battery needed to operate. But great work and I as most people enjoy watching these.
Sei un grande!! Mi piace troppo guardare come fai questi componenti!!:D una volta però lo fai un video di realizzazione di un pezzo al tornio senza Time lapse?
Brass looks beautiful, You were on the right track with the aluminum, just need to buy Harris Al-Solder 500, and stay-clean flux, you can solder with a soldering iron.
Nice yup that aluminum brazing rod can be a mess sometimes but you have to tin the surfaces it will act like solder .Takes some practice. The brass tank was the right way to go unless you tig weld it anyway. Might try putting anti splash baffles in though for when the tank starts to get low 👍
You need to use aluminum flux if you are using a torch and aluminum sticks. You need to apply it to the area you want to solder and then heat it from behind. When you touch the wire at the area the flux will suck all the aluminum and make a perfect weld.

Yes. And use stainless scriber to break the oxide layer on cleaned aluminum through the melted braze.
Richard Jordan Jordan in addition, flip your jig around 180° and blast heat at the joint directly instead of only on one side.
Yes, he used a better method for the brass. See a lot of people on RUclips heating solder or rod but insufficient heat on the parent metal.

The fuel tank would need some internal plates to avoid having the fuel moving around to much and losing corner stability and handling
I swear that process had a name I just can't remember it!
Baffles?

I think it was about $1200 for me to get setup to do TIG in my garage. That's with buying the argon cylinder.

You have got to be the chillest youtuber of all time
at the end of this video you DARE to label this wondrous exploration a MESS???? NO WAY!! been following awhile- totally enjoy your videos.
Ça faisais longtemps que j'avais plus vue vos vidéos sa me manquais alors je m'abonne.De vous voir faire sa a l'air tellement simple.
Glad you changing the fuel tank looks much better
You can fix anything man.....AMAZING
soo satifying
he's literally building a real car but with exact but smaller parts!!!!!! genius or what!!!????
I have never seen you make a bad video, all of your videos are awesome!
Great to see you try new things too, sky is the limit for future builds
Lovely work. That is a very cute & elegant fuel tank.
That is the nicest fuel tank I ever seen
This is awesome. I need to build a tank for a model aircraft and this has shown me how it should be done. Thanks.
Simplemente un Crack en todo lo que haces. Gracias por tus videos. Un saludo desde España. Marco
The fuel tank alone is a work of art,I hope one day you build a miniture V8 engine,similar to the Connolly V8
Esse cara trabalhando é uma verdadeira obra de arte

Nada como um trabalho bem feito e com ferramentas adequadas. da gosto de ver. Parabens !!
With all types of brazing the material needs to be so hot that it melts the rod. And proper cleaning ensures that it flows properly. Love you builts!
For such a small tank, angling the fuel gauge fittings on a 90 would give you better visibility at the top and bottom of the range.
You should make a mini face mill for your CNC mill.
That's awesome ul never be stuck for rc parts or whatever is ur hobby cool piece of equipment 👍
This guy is an artist I swear
the fuel level gauge is so awesome !
This is the fastest 9 minutes vid i seen.... Need more....

I liked the fast forward of the end plate soldering, you can see the metal deflect to the varying heat.
At 4:13 it's interesting how the stack sways as different parts expand from the heat.
Your builds are amazing i hope u keep up the good work👍👌👍
That's a really nice looking fuel tank, take care of yourself and loved ones.
Very nice fabrication... excellent result.

I love the brass work. 👌
Got excited as hell for another video on this project :D
This guy is awesome.! I like how he just opens the drawer and pulls out a sheet of aluminum $$$ like its nothing lol made my day
I love all the awesome things you make
Dude,I SO THINK that "Brass" tank looks WAY BETTER than that aluminum one!!! Great Job!!! :-)

danggg. just come across his vid series on this V4RC. i have to say, im truly amazed.
This is beyond passion
Super tallented, AAAwesome video editing. Im all eyes and ears watching you're skillful clips.
Thankyou Sir
This was the perfect excuse to buy a tig welder.
And there's many hours before he can tig thin sheet metal. :)
If he master the flame on weld system, he could be better than tig welder
Seriously of all the GREAT kit they have, i'm suprised they don't have a welder yet. That 5 Axis CNC Mill alone...

Looks so good in brass..... a work of art :)
Love the projects. Keep up the great work
Brooo!!! i love what you do since i watched your first video! keep working like that, you are doing an amazing work
That must be one heavy lil vehicle lol but truly worth it for all the innovation you're putting into it
for that braze, you really should be preheating the entire part first.
Also, those cheap ally brazing rods need far more heat than you're supplying. They will flow in a clean joint when heated enough.
From my understanding you shouldnt melt the rod with the torch. U need much more heat in the base material so the rod melts when in contact with the base material.
Id also say some flux is needed he's putting way to much heat into it
Soldering ≠ Brazing
This thing is going to be wild. I wonder if someone could make you one of those flexible fuel cell style fuel tanks like they use in F1 and other racing cars.
A showcase of your work space would be nice
