Funny you would have had so many criticizing the build, such as you said; death trap, flimsy. Goes to show how ignorant people are and yet think they know it all. lol. This is essentially a Unibody system (body severs as the frame and support). it is a common weight saving design in automobiles. I guess this is really more a Monocoque frame. but very similar. I used the Unibody as a more common / understood name. Some of the fastest supercars ever made are Monocoque, Koenifsegg's Ferrari, Lamborgini Aventador, Ford GT, Bugatti, McLaren, just to name a few. Just incredible work,,, thanks...

HI, have you thought about a charge cooler over the engine, should provide for a shorter route for boost, and would not have to go through the cabin, could also make for an interesting engine cover design.

Yeah, looking into redoing that charge tube once again. Might have to keep the two tubes separate until they cross the engine. The 3 inch tube is just to close to the deck lid but with two, I think I can do it . . . then I can get viewers to stop hounding me about heat in the cabin. Ha!

[@mchristr]

For those who are skeptical concerning the strength of composites, you should see how thin is the fuselage skin on a Boeing 787. There's less than a 1/4" of composite separating you from 600+ mph wind and subfreezing temperatures. Yes, the strength is found in the diameter and the framing in the barrel. Regardless the airframe will last for 20 or 30 years of almost daily service. It's all about proper design and materials.

Hello from algeria ❤️❤️❤️❤️✌️

[@94JAVS]

Hey man, stupid question. I've noticed that you put a lot of fiberglass. Do you plan how many layers you are going to add or is it an addition process until you feel it is as solid as you like? As a designer I get obsessed with the thickness of every piece I'm working with and how everything fits. But this scale is completely out of my knowledge and I wonder how important is to consider that detail when working on a car.

[@94JAVS]

Ok, I just finished the video and you explained how you planned it lmao now I feel stupid 😂

[@BuilderCreator]

I might also add, that I have targets, but will do some testing when it gets close to finish, (the tub) and if I need to I can add more structure until I achieve the goal.

[@assarstromblad3280]

Nice, thanks for answering all our questions about the tub, I was a bit worried it would be too weak before, but when I saw this I changed my mind. Do you have a target wheight for the car? seems like that many layers of glass could be quite heavy?

On the contrary; I think he’s doing an awesome job and he’s been clear in previous videos that he isn’t planning to make multiple Arete cars this way.

[@BuilderCreator]

For sure! The answer would be to scan the finished car, with all its new added door jambs, seals and flanges and from that re-do the tooling. Then build it on a tubular steel (or bonded aluminum) chassis.

[@BallinBuilds]

[@andygray563]

I know this is way too late but the size of the roll cage steel looks way smaller than I expect of normal racing regulations. I think it would have been beneficial to investigate required designs way before going your own way. Love your just-go-for-it approach with everything though.

[@BuilderCreator]

Here is a recent video with the roll bar built- kzbin.info/www/bejne/bWSZfYVpq8-ig5I As mentioned in the video the roll cage is just to supplement the integrated composite roll structure. I have thought over the "racing" probability for the car, but think at the very most I might try Time Attack and then in a lower class, that does not require any regulated roll structure. Thanks for watching.

[@michaelmoore1403]

This is not a chopper gun fabrication, chop strand matt and polyester. This very strong.

[@Skwisgar2322]

Agreed, you could probably drive a monster truck over the tub even without the steel hoop.

[@AdamsWorlds]

Would it take much work to carbon fibre it instead of the fiberglass? (sorry if sounds stupid but i thought it was a similar process laying down in strips). Just wondered why the material is not used more in stuff like this. Is it cost / ease of use or a mix :S. Looking really good by the way been fascinating to see this whole process.

[@PragmaticWisdom]

It directly comes down to the cost, he's mentioned it in previous episodes. Jay has wanted to keep the Arete as cost effective as he can. The cost of carbon fiber is very expensive compared to fiber glass. For comparison, a 50 yard roll (roughly 46 metres) of 4 inch wide Fiber Glass Tape, is US$59.95. Where as, a 5 yard (roughly 4.5m) and slightly thinner 3 and 3/4 inch wide Carbon Fiber Tape, is US$219.95. So to put it in to a much harsher view, you will need to spend US$2,199.50 to get the same length of Carbon Fiber compared to Fiber Glass. Now you can see, that the Arete project would quickly become very expensive, if Jay used Carbon Fiber in the entirety of its construction. Yes he would have to use less materials to gain the same strength, but at the sheer price difference, it would still come out cheaper to just use Fiber Glass and some additives such as foam core, and honeycomb structure.

[@AdamsWorlds]

@@PragmaticWisdom whow yeah that’s a fair bit more, I was expecting it to cost a bit more perhaps double but not that much. That’s crazy expensive. Makes total sense I must have missed that episode or part. Thanks for the explanation :)

[@BuilderCreator]

As mentioned it comes down to cost. I have calculated it to be about $17,000 more expensive to execute it in carbon fiber. (for only a 20% strength improvement over S-glass) And if one wanted to justify moving to carbon fiber the molds would have to be re-done to take advantage of vacuum infusion, (another expense) as carbon fiber typically does not lay as well as glass weaves.

[@AdamsWorlds]

@@BuilderCreator whow thanks for the reply. Yeah can totally see why that would be avoided ouch thats expensive.

[@mrpurcountry]

I don't see any structural Integrity in the roof or the windshield support this is where the car will Flex, I'm curious if this is laminated with epoxy or fiberglass resin.

[@BuilderCreator]

After I get the "rain channels" fabricated the A-pillars will get boxed in (around the carbon stiffener) and tied to another core that will run across the roof to the Nomex honeycomb panel. The window (as in most cars) adds to the stiffness. All epoxy resin with S-glass fibers.

[@jonstarritt848]

This is a great custom supercar build! To get it certified to be road legal do you need to build a few more body/chassis combinations for crash testing? Or do they accept engineering models with FEA? I'd hate to see you go through all the work just to have it seized by the government so they can "keep you safe from yourself." (Which is the rationale I imagine they'll use.)

this has been something I've wanted to say for awhile now, but i think now is the time and i realize this is a first off and you can't really do anything about it. When you are doing these piece by piece layups and letting it all cure in between these layups, you are not getting a chemical bond, you are only getting a mechanical bond. with composites, the chemical bond is what makes it strong. I'm sure you must know this, but i don't want people unfamiliar with composites walking away thinking this is how you do it. it's not. you do your very best to make sure everything is done while the next layer to it is still, at very least, tacky.

[@customfabrications]

@307Driftwood Very true. I have some experience building composite home built planes, and we applied new layups to cured areas all the time. As long as it’s prepped properly, no big deal. Imagine trying to lay up the entire thing in one go...
