Matt, I learned a trick for checking tanks for leaks. Put a few drops of red food coloring into a small bottle of alcohol. Pour a few oz's into the tank and swirl around all the welds. If there is any porosity the red will show up! Empty the tank back into the bottle for future use. Beautiful little tank you have there. Wish I had a plasma table 😂
We call that "dye penetrant testing" and it is pretty standard for any pressure bearing vessel.
Love that tank.
@@the_inquisitive_inquisitor That’s not what dye pen is lmao
@@butters_ it's poor people dye pen. You're using colored liquid to check for leaks; it's the same shit
Top job as usual Matt 👌🏼
Man o man you can lay it down. Fun to watch. Thanks Matt.
More beautiful work, including the starter motor, alternator and water pump plate of course! 😊
Great work Matt..must have missed this one ...envy is a sin...I am a sinner..
insane welding skills!
Aluminum is the least polite metal to weld; it doesn't even have the decency to glow before melting!
Anybody who can run a bead like that on their first try is a great welder in my book.
Just a note on rivnuts from someone who has spec'ed them in high volumn production: The way you have fitted that tank with clearance holes you run the risk of spinning the rivnuts. Probably not a concern in this case as the torque for the fittings is low. They are designed so the part that bolts on contacts on the head of the rivnut so as you then tighten the bolt the rivnut reacts again the fitting and tightens. To stop the rocking use 3 fixings.
Cracking video as always your welding and fabrication skills are brilliant 40 years ago we used to use a dye and spray combination to check for leaks on dry cleaning fluid tanks which were 20 gauge stainless the welder Mick insisted that they guillotine the sheet metal with a shimmed gap between the blades so it left a burr so that he needed no filler rod and all welded with a scratch start welder.
The old one was a swirl pot, it's good for getting air out of the system. The immediate example that comes to mind is on the old Lotus Europa.
CAM called it. Its a swirl pot. Inlet is tangent to round body making the water swirl or cyclone air is able to easily escape. Handy if your race car has crazy amount of external water plumping and a mystery air leak causing air pockets, hot spots air locks etc. Not from personal experience 😉
Love the tip about using a bigger hole with a rivnut 👍 Countersunk rivnuts are available but I've never been able to get them. I'm doing an aluminium Tig course next week, can't wait 🙂
Sweet. A lot of welding but worth it, fits a treat in there.
Good looking welds too.
Aluminum is my least favorite metal to work on.
Sitting over the rivnut is genius! Ive always hated how riv nuts sit proud
Looks like what was replaced was a swirl pot set up for eliminating air from the cooling system. The previous set up must of had issues with air getting into the system. The height of your tank should be good enough to keep air out of the cooling system and you've probably got a better system than what was originally with the engine. Love watching your vids!
Nice bit of alloy welding good to see how you used the wire brush to clean the alloy . not many people know that
I wish my tig welder did welds as good as yours.
I rekin ive got a faulty unit. 🤔
✌️Peace from Melbourne Australia.
Pure gold watching you construct that tank looks the biz .
Nice job Matt ,great work 👍
Cheers
Great piece of work.
Fine bit of TIG welding there Matt!
Brilliant work Matt absolutely brilliant.
Superb work as always matt 👏
Good tip about the inserts, I've tried to make them flush by countersinking the holes but that doesn't leave much for them to grip on..
Top notch you don’t see many that can weld at this level 👍
Agreed, that's some very neat aluminium welding!!
Aluminium hates vibration. It also reacts with steel creating an electric couple. Liquid tanks are normally held by bands, bcz welded brackets tend to rip off. Pressurized tanks are round, to even out the pressure throughout the material. Where are you going to mount the expansion tank?
Awesome Matt great work 😊
You do fine work mister.
Counter sunk rivnuts, I just used that same filler cap for my header
Top Job!
Looks good.
Beautiful
Superb quality...
Excellent video!
Great work as always Matt - thanks for sharing!
Pretty clean welds
personally I'd keep a piece like that in the flat position, but that's just me
Lovely work Matt, it's annoying how often the mechanism of a box brake get in the way of the thing you're trying to fold!
Perfect!
Or is it a bird house? Brilliant work either way.
Cheers mate.
Matt, train me up man please. I need to learn the ways Sensei
Who's playing with the bastard file?😉
the usual top quality work.
Lovely work!
Cheers mate.
A work of art mate.... LAG 👍
Slick.
Pretty snazzy 👍🏻
Look fabulous as always 🙂🙂
Brilliant. What grade and thickness of material? Thanks!
Good Stuff Urch, gona be sweet!
Maybe from the shape of the other tank they were trying for a swirl pot of some description? from the angle of the inlet and outlet they would promote a vortex on entry/exit??
Good job!
Nice tank Matt where do you get tank fittings from I do a bit of aluminium work some times I always end up scavenging parts from old tanks
very good job man 👍💪
Nice job m8
nice job mate
I like your old intro..
Superbe travail 👍😁
What goes through your mind when you walk amongst mere mortals like ourselves?
по работе как всегда на высоте! горизонтальные карбюраторы без воздушного фильтра?
Tidy👍
The way you put your fingers on all those splinters and burrs makes my skin crawl.
Эти швы не выглядят как те, что сделаны полуавтоматом. Я научился делать такие же классные сварные швы и называю их швами urchfab. У меня нет опыта с тем, что ты показал в ролике, но у меня возник вопрос: это просто невозможно сделать также красиво и классно или в этот раз ты решил просто сделать бак без старания?
Профи👍
Beautiful work as always Matt, What thickness was the Ali and what were your Tig settings? The welding looks outstanding.
It might be worth making a gasket to go under it to prevent galvanic corrosion?
Bring back the clap please..
Hey Matt,
Started tig welding at home , got the basics on stainless and mild but have yet to venture into aluminium but need to , any pointers ?
Cheers mate.
Aluminum melts before it glows, so you can't gauge your temperature based on color.
You just have to know how fast to move and how much filler to add to manage your temp.
I learned to TIG aluminum first, so I got the muscle memory before I learned to tell temperature by color.
