Mock up of the form for the rear diffuser/air straightener. As with the other pieces, will get turned into carbon.

(we went through about 50 versions of this shape before settling on the one we liked...) https://farm8.staticflickr.com/7558/...23ba809b_b.jpg https://farm9.staticflickr.com/8673/...67e77df3_b.jpg Cut in steel on the plasma for now. These will eventually get waterjet cut in aluminum with machined detail. https://farm9.staticflickr.com/8563/...9e462518_b.jpg https://farm8.staticflickr.com/7569/...cb27017b_b.jpg Starting to look a little racy... https://farm8.staticflickr.com/7560/...d2e7ec7a_b.jpg |
thoroughly enjoying this build.

That rear is outrageous!
Awesome stuff. |
Wow !

With the shapes dialed in, we needed to digitize the surfaces to both make the slight changes and additions we wanted and so that we were able to mirror the flares for the passenger side.
The guys from Exact Metrology were happy to assist in the process. Using both the Romer arm and Surphaser, they were able to capture the detail and parts of the vehicle we would need for the next steps. Science! https://farm8.staticflickr.com/7508/...70b85b95_b.jpg https://farm8.staticflickr.com/7529/...e605263b_b.jpg https://farm8.staticflickr.com/7470/...9de9e564_b.jpg https://farm9.staticflickr.com/8670/...bd4aca38_b.jpg At this point, the file they captured was then used as a base for us to generate the final surfaces. Wile forming everything by hand and scanning to 3D is a great start, the ability to form a 'clean' surface model in 3D would allow for a perfectly smooth surface. It would also afford us the option to break each surface into parts and add all the structure needed for it to become a suitable plug for a mold to be made. It was also way more efficient to add details at this time in the computer like the fastener recesses and vents.

With the 3d work complete, the files were sent off to be machined (due to the size we couldn't do it here)...more on that later!
The car could then be removed from the table and the fab work could continue. Since we were now able to get under the car, we set about on the 180 degree headers and fabbing up the stainless exhaust!! https://farm9.staticflickr.com/8609/...9e0a8fce_b.jpg https://farm8.staticflickr.com/7466/...b6bf1211_b.jpg https://farm8.staticflickr.com/7570/...937b8a3d_b.jpg https://farm8.staticflickr.com/7567/...4a93de40_b.jpg https://farm9.staticflickr.com/8651/...0e16d353_b.jpg https://farm8.staticflickr.com/7550/...45c982df_b.jpg |
ok, now your just showin off.
|
Can we get a video of this beast running?
|
Yesh those 3d scanner things are great - I got one from Harbor Freight recently that I've been using. :gitrdun:
Where did the CF nose come from ? who does your custom CF work ? Can't help thinking I'd rather have the engine 2" lower than kick ass 180 degree headers though. Really appreciate you guys sharing the details. So beautiful and so much to learn from. |
