I love that you use paper templates, an angle grinder to cut everything from paper and dimension steel, quickly made jigs, Mig for *everything*. It's realistic. It works. Yes I also love CAD, and CNC'ed billets, and waterjets, and lasers, and Tig - but there's a place for all of it.

Small tip for you when making identical brackets. Cut out all your blanks and tack them together before you drill them. That is called gang drilling. That way you know all your holes are in the same orientation/spacing. Leave them tacked when you grind them to shape too. Removes some margin of error. You do have to use normal twist drills and not a step drill though.

4:48 "I did some CFD early on when designing the car" are words never before spoken by a guy building a car he designed, in his garage! Seeing the beautiful engineering you are putting into this monster, it doesn't surprise me though. Loving every video, subscribed!

How to properly build a race car with an angle grinder, a mig welder and some steel tube - DIY in your basement. This is what should young kids watch not Love island! So excited to see it running on the track. You're awesome!

Enjoying the science (engineering) behind every aspect. No cowboy fabrication. Patients is an acquired virtue waiting for another upload (that skill is in R&D phase)

Man i am so excited. Was waiting and felt like forever. Got the alert in the subway and immediately got out cause signals arnt the best there to watch a video.

Every day SK8215 uploads is a good day!

unbelievable. This is the spirit of the privateer. Such a great build series.

Soooo close to the first test drive! Glad i found your channel so i can watch it progress real time!

Yeah boi. So glad I'm imsomnic to see this as soon as it came out.

That is awesome dude, big ups for the calculation, so good!

Very nice job!

This video is one of the most happy things in my week! Good job!

this dude is a DIY beast!...deep respect.

You my friend are a very talented man, this is going to one very impressive race car,must be very satisfying building it like this. Looking forward for the next video!

Loving this build and can't wait to see it completed. I also enjoy that you explain everything in your videos and are doing it in a way other real people can at home. 👍👍

This is awesome, now I start to see your vision, job well done!

dude this is by far one of the craziest car build on youtube. You really deserve 1 million subs

Hi! I really like your project. I would like to suggest something. Please make the rear wing adjustable longitudinally. I say this because of the aero balance. I don't really see how your car will produce front downforce (I see the splitter but the frontal area of the car is so small I don't think there will be a lot of pressure above it.) So I did some calculations based on your design from part 1: If your rear wing makes 200 kg downforce and the car weighs 1000 kg (500 kg front 500 kg rear), the distribution will be 452,2 kg front, 747,7 kg rear. That is 37,7% front, 62,3% rear. Yes, the rear wing generates 50 kg lift on the front tires(which is 10% of the original 500kg, not much but not negligible). If you had your wing above the rear axle the ratio would be 41,7% front, 58,3% rear. Having more rear downforce is good for coming out of corners (less whellspin) but the car would probably understeer. So my suggestion is that you build the rear frame so that you can bolt the rear wing mount in different positions. This way you have the option to change the aero balance. This is not difficult to build and possibly won't even change the weight of the car, it just needs a little bit of designing. If you look at F1 or LMP1 thy dont have the rear wing as far behind the rear wheel as production cars because the dont have a rear window (except Mazda 787 for example, but that is to help the the diffuser and needs proper design). (I know I ignored the diffuser and other factors, my point is not the exact number. The point is the ability to tune the car.)

*Very exciting, it's all coming together so nicely.*

Most underrated build channel on youtube... Waiting for the antirollbars now

Amazing. Have been watching from beginning. One man formula 1 team. Keep up the good work.

Oh I can't wait to see this amazing car running and tearing up the track. Good luck man!!

So stoked for this project 👌🏼

One request. Pls dont use material gloves, when you drill something (or operate anything, that have fast rotating elements). Its much better to get chip in your thomb, than to screw in driller. And keep doing it, this is just insane amount of work and information for others :)

Love this project and can’t wait for it to get finished 😀😀👌🏻👌🏻🏎🏁

Congratulations on getting it on all 4’s!

Really love all your work. Looking forward to the next video 👌👍

Really enjoyed this video as again it’s very informative and inspiring for me to see what you are doing on this project.

yo this is the best series on youtube

hey just a heads up those you never beat bearings into place ALWAYS and i mean ALWAYS press them in they will wear our very fast with time due to the stress you applied with the hammer and socket you used

Superb, well done.

It all looks so simple. If only I had the funds and tools, I'd try to build my own. Only hang up I might run into is I'm limited to very basic geometry.

A tool company should be dropping off a tig welder, bearing press, cnc plasma machine. Not that he needs it, he's doing great with the basic tooling he has.

This is great stuff, I enjoy this just as much as the bad obsession motorsports channel and the awd mini cooper powered by a celica gt4 drivetrain.

Great as usual. Wonderful.

Great as ever! Well done!

look so forward to your vids great work keep it up

Impressive!

Awesome!

Hi man, Are you sure the shock absorbers can work horizontally? They are usually installed with a small angle that allows hydraulic valves to work properly.

Wery vell project. Like. Hi from Moldova.

You are just awesome. A Fan from nigeria

there must be an extreme amount of griding dust in your shop will all the angre grinding and the chopsaw but its cool to watch some good old fassion fabrication

I feel like Oliver, “More please”.

Your design skills are amazing man, and your understanding of the physics and geometeries definitely show...but god damn, your welding could do with a lot of work and some extra patience. The way you've put some of these brackets together and especially the intake and the driveshaft are horrific. I really hope you get better on the tools and revisit some of these flaws becUse this project is awesome

amazing

Yipeee! Its here!!

When welding with a mig or mag, you should be pushing instead of pulling. I learned it that way, for a stick and tig welding you should pull. Sorry for my bad english, its not my mother's tongue. :p

yessss

I love the build and the sharing of knowledge. But the whole structure is so heavily dependent on welding quality that I am curious how well it holds up. Weldments do not like constant bending and vibrating forces - something a racecar is subjected to all the time. The weldments will fracture and give up, resulting possibly in a catastrophic failure. As a positive note... all kart chassis are welded and they seem to hold up.

thank god you have new welding gear cause the previous results were horrible

Very nice

I was under the impression that your rear suspension set up would be similar to the front... I'm not an engineer but I suspect that your rear will be bouncing like crazy and bottoming out. Best of luck! Also surprised you haven't considered a driveshaft loop.

Amazing , you da man!

My god those welds are shocking

This looks pretty awesome but I was wondering... down the road when you need to service the diff, how will you remove it? That hole up top seems like it might be full of body panels. And as always, it's too late to mention but wouldn't it make more sense to have the push rod stuff in front of the axles to keep more of the weight closer to the center of gravity instead of having it sit at the edge of the car?

What was the reason for making the rocker plane geometry at an angle from the lower control arm pivot axis? Would that not make the motion ratio more digressive with wheel travel?

Are you going to make the panels of the car in carbon fiber

Counter lever: Are you welding the steel plate to aluminum ring?

Safety first drive shaft loop

Where did you get the bearing race for the catileaver? And where did you get the coilovers?

You may have covered this somewhere already, but is there a reason you don't just have a local shop plasma cut your plates/brackets? Seems like you'd save a good bit of time if you weren't having to cut & trim brackets (that you appear to already have modeled in CAD) - even if you still choose to drill the bolt holes in them.

Sooooooo,,,,,,, this is all mild steel and MIG(wire feed) welded???????

You should definitely make sure your bellcranks are in double shear, not single.

Is that going to be enough travel? Are you planning a lot of aero?

What material have you made the chassis out of to have not had it rust at all after this long, or do you just not have any humidity where you live?

Which motorcycle are those shocks for? Great work btw!

Wouldn't it be a good idea to take the car to an alignment shop with proper equipment? Just to make sure you have done it straight. Better do it now than lwter when the car is fully assembled. Cheers mate, awesome project

Please make it a two seater so I can dream about being taken for a ride around the track in this amazing home built car.

I like your coilover shocks what brand is that n is it expensive

Great video! I was just wondering how you chose your damper? Did you already have brand in mind or did you compare several damper and then choose, and on which criteria did you choose it? Thx

Have you considered placing the radiator(s) in front of the rear wheels? I would think a twin turbo V8 is going to need all the weight it can get over the driven wheels.

2:45 welding while rubber bushing is co close? You've probably damaged it with heat. Also using ball bearings in heavy loaded places when they only travel 20-30 degrees is not a good idea, but who am I to judge =)

Spring rates look soft.

Amazing work. Sorry what material are you making the chassis/suspension out of?

I think you should redesign the rear of the bodywork

Hello, following your work, very beautiful. I have a project for a tricycle that will be assembled on a Honda WRV automatic engine. Can you give me a tip regarding the shock absorber the suspension will be double A, the motor will be transverse. I apologize for the English I'm using a translator.

Hello. Where did you buy the balljoints?

rear wheel rates need to be about 10-20% higher than the front

I'm a little surprised that you mounted the cantilever rearward since the anti squat moves the tire forward under suspension compression.

Why did you not have all the plate parts laser cut? Cost?

Hello. What kind of shock you use?

can u please add some overhead rollbars, i think cabriolet style cars are so unsafe, if the head bar sticks/digs into ground well there goes ur head, i dont know right words but hope someone gets me point :D

U going to remove everything and paint the chassis? :) If so,what color? Great work, keep it up :)

In the last video you talked about reinforcements around the rear end and I thought that would add braces to the Toe bar link mounting points on the frame. Right now that look like that have no triangulation and look a bit out of place. Does that link not take very much force allowing it be mounted that way? If that is the case then they look like an after thought and just do not look as well designed as the rest of the car. This is not saying you should change it if not needed and I get you may not be done back there.

What motorbike did those coilovers come off?

How will you take the diff cover off?

Are you planning on installing Anti-Roll (Anti-Sway) bars? Fascinating stuff!

after that

Are there better small shocks that provide rebound and compression damping?

I know those are motorcycle coil overs. What brand and specs?

What Shocks u use?

If you just attatched the two coil overs together, and not to the frame, wouldn't that act as an anti roll bar.

Are those motorcycle suspension?

I can’t remember if you said before, but do you plan on using sway bars at all in your design?

This is how the other Cartubers used to do the work, before they all got corporate sponsorship and became unrealistic caricatures of the DIY spirit.

Please add a Drive Shaft loop! You do not want the drive shaft coming apart at 200 KPH.

The donnuts are closer

would it be beneficial to change the differential to something more tune able? or do they make clutch type lsd's for that unit? would you want a clutch type? going to have to rewatch some videos, you probably went over it in the welded diff video
