Love your work. Would like to get one of these progressive auto designers to draw out a super roadster and build a limited production on a tube chassis, Chevy powered, etc. Great, some day i will visit your establishment. keep up the excellent work! LRSS46
Good case of too much knowledge and not enough practical application! But.... it was a great suggestion! And a good explanation! You guy's do great work!
Love what you guys do, your quality reminds me of early Ferrari and Maserati's from the 50's It is the ultimate Cobra, if I had Jay Leno's money, you know you guys would be building mine
Wow, I'd love to tour your shop some day. You've got to show some more sheetmetal skills. Those kinds of skills are on the endangered species list. Keep up the good work.
@porsche1977924s, unfortunately aluminum doesn't stamp very well. If it did, far more car bodies would be made from aluminum. Aluminum galls on the dies and has very poor deep-drawing characteristics. We do make matched dies for some of the shallower drawn parts we make.
Nice job!!! I want an information please: How much is the power (in tons), of the hydraulics at this machine? I'm interesting specifically in the die lifting up system... Thank you, keep on the good work.
was/is the body on the original daytona prototype more crudely constructed? I was under the impression that it was just pounded out over woodem forms....
What are the typical cost associated with starting a production run on a part like this? I want to produce an aluminum hard top main shell for a roadster.
It's rare to see competitively priced parts made by almost traditional means. Some specialist knowledge being employed here & it looks deceptively simple.
Is that anywhere as strong as the superplastic formed parts? I realize that 3003 is a work hardening aluminum, and that stretching it to yield elongates the grains and makes it stiffer, but you had a guy slam on that other part.
I really don't think this is how they make the aluminum body parts, I bet they are put a big press, just like how American Choppers make their motorcycle fenders.
I always wondered how this process happened. Thanks for posting
as a traditional sheet metal worker Im jealous to see a weeks work done in 10mins !!
Very cool, Always wondered how they formed those panels. Beautiful & amazing all at once.
@BatCrazyTalkCustoms The lower die is made from 6061 T-6 Aluminum.
We have hydroformed many parts over the years. We found stretch forming to be more accurate.

Thanks! We are working on some videos of the Daytonas we make for Shelby right now.

Once it is annealed, does working it give the Aluminum its hardness back or does it remain annealed?
@@AFugal anytime you move metal, it work hardens.
We like to make our dies from 6061 T-6. It machines well and is hard enough to wear well for a hundred or so parts.
Highly Educational 😎
@LRSS46 ,
Thanks for the kind words. You are welcome any time!

@fastalexONE We have a 160 ton stretch press.
Wish I could reply.... nick seam
Its 3003 H-O. The O means its annealed and at its softest state.
@maison0blanche
Thanks for watching!
Ok its heaps quicker than doing it on the Garage floor,
Question:could you put sheets on at once?
was/is the body on the original daytona prototype more crudely constructed? I was under the impression that it was just pounded out over woodem forms....
The original bodies were pounded over wooden forms (metal reinforced) and shaped with an English Wheel ("Wheeling Machine").
For 0.063" it seems really soft, what aluminium did you use?
Who could possibly give this a thumbs down?
What are the typical cost associated with starting a production run on a part like this? I want to produce an aluminum hard top main shell for a roadster.
Design, tooling, programming, machining, materials, and testing to figure out how to actually make the part--figure $30,000-$50,000.
Oh my goodness that looks like an expensive part.
Step one: Win the lottery
Step two: Call Dave Kirkham

its like a normal press tool job , except the guys lost half the tooling
What about hydroforming the aluminum? No hand working the piece.
@porsche1977924s you can't form aluminum of this complexity with a single action die and that kind of press speed. have u ever designed a die?
Is that anywhere as strong as the superplastic formed parts?
I realize that 3003 is a work hardening aluminum, and that stretching it to yield elongates the grains and makes it stiffer, but you had a guy slam on that other part.
The SPF parts are stronger.
3003
stretch the sheet out of it!!

Well...we have made almost 1,000 cars this way...
A machine for people with no talent.
There's one in every crowd....
