Better.
This one actually goes, not a show car :)

On a separate note, the design and pieces for the DRS are coming together.
We're working on CFD analysis for our DRS on both GT-250 and GT-1000 swan neck mounted wings, so that we'll be able to tell how far we can push it before the risk of wrecking the car becomes all too real.
This may become a new Blackbird Fabworx product, though at a price tag that is not for the faint of heart.

nice work. I like the top center section of of the cage... alot. I was recently a passenger in a car with diagonal top bar on track. perhaps partially due to seat mounting.. but it was not.. ideal..

Blackbird Oct 11, 2016 10:58 PM

One of the first steps I take when designing a cage for a customer is asking them whether the car will be ever be used with a passenger seat.
If the answer is yes, they get a cage that is passenger head-friendly -

If the answer is no they get the driver friendly / passenger unfriendly / triangulated roof setup -

Such Carbon. Many honeycombs. Wow!

https://cimg2.ibsrv.net/gimg/www.mia...3a1062ce28.jpg

CF / Nomex honeycomb panels for Morpheus' flat bottom are here, bubble bottoms be damned.

Also here's a nice pic of the DRS actuators that arrived today as well -

Like it?
Don't like it?
Me neither.
Those are actuators in the box, however they are not the actuators that I ordered, it's the wrong part number.
And so here they are, waiting to be picked up by UPS... and this is how a comfortable timeline to complete the DRS system becomes compressed due to no fault of my own.
I hope we can still make it happen in time for SLB :facepalm:

Blackbird Oct 19, 2016 06:21 PM

The fun and games continue!
Flat bottom in progress, using CF / Nomex honeycomb panels.
Measurements taken, hardware ordered, still need to machine inserts.

https://cimg6.ibsrv.net/gimg/www.mia...ed727b8875.jpg

Also fabricated wheel stands to set the car high off the ground without lift arms in the way.
Makes life easier when building a flat bottom.
Done and done!

Awesome artwork on the hood. Props!

Blackbird Oct 20, 2016 07:45 PM

Aero front fenders underway as well!
The fenders got the rear portion trimmed off and then came the scary part - creating the vents -

https://cimg5.ibsrv.net/gimg/www.mia...5c76e15648.jpg


A little bit of filler, sanding and some prep and this fender is ready for paint -

https://cimg6.ibsrv.net/gimg/www.mia...2a9284f7d2.jpg

Rinse and repeat on the driver side :skid:

OneTwo Oct 20, 2016 07:53 PM

That looks great. Can't wait to see what you end up doing to the lower sections.

Blackbird Oct 20, 2016 10:10 PM

The lower section will have a composite filler panel.
Already have the design in my head, I'll probably get to it next week.

Blackbird Oct 21, 2016 03:01 PM

Had to grind off some bondo from the driver side, but after some light massaging I got it looking right :)

Turned out really nice Moti, may steal part of your design in the future. What are you doing for the bottom part of the fender before the door? Using a second fender's bottom piece or just cut/weld some metal in there?

Blackbird Oct 21, 2016 05:27 PM

Thanks!
But let me pull an Aidan here for a sec ;)

Derrrrrp lol

Blackbird Oct 22, 2016 07:40 PM

CFD results for the DRS are in and new (hopefully correct) actuators are coming in on Tuesday.
50/50 chance of DRS ready for SLB, I'll take it!

Blackbird Oct 27, 2016 07:59 PM

Flat bottom update!

I did manage to find a few mins and machine the flat bottom inserts and we were ready to start cutting.
Let's not screw this one up, that'll be expensive! :giggle:

https://cimg3.ibsrv.net/gimg/www.mia...40895b4318.jpg

The inserts are machined to be able to use a counter sunk bolt so that we get the flatest flat bottom possible.
I will have a few small button heads protruding down in a few places because they make more sense, but for the main load bearing bolts I machined the inserts.

The insert has the center bore counter sunk, then a groove cut into the side and then two small holes drilled into the groove on opposite ends.
We take the carbon panel and drill the bottom side with a hole saw, just deep enough to penetrate the top layer of the carbon.
Then use a carbide bit to hog out the nomex so that the machined insert sits flush in it (full depth).

Next we use a tip top epoxy and inject it into the insert in the small hole, the groove in the side of the insert allows the epoxy to flow into the honeycomb full 360 degrees and by the time that the epoxy starts coming out of the opposite hole, it's done.

Definitely more involved than your average bolt and washer deal but oh so flat!!

https://cimg6.ibsrv.net/gimg/www.mia...c05be6e047.jpg

Still need to put some finishing touches on it, but the first panel is getting close.

Scaxx Oct 27, 2016 08:10 PM

Damn those are sweet, are you going to be extending the exhaust? Or are you still gonna dump it there when the floor is finished?
