Compare these pics of the original 1965/66 Sunburst wheels with the current Rocket Sunburst wheels, and while you will see the similarities, the Rocket wheel is quite different. I like them.

Great reproduction, but different.

Cheers
Greg

And you Greg (Lucky Dog) just happen to have a "Real" set ;) I could add Beautiful, but then you & I know that :) Cheers TommyRot.

Hi Dan Case. You asked: Do they hold air? One of the wheels for CSX3298 had an inner tube inside the tire because of pores (lots of them) all the way through an area in the rim.

I've had my original Sunbursts on my car since 2007. I guess I've been lucky because I've had no problems. A little leak at the bead (fixed) because of some corrosion caused by the tire mounting lubricant/sealant (????) and one bad valve stem seal.

But no porosity leakage or cracking.

Cheers
Greg

That's good. 1960s castings of anything could be porous. I had a very porous COBRA intake once. One of the rocker arm covers on our red car has a porous spot between two fins and weeps oil a tiny amount that is easy to keep wiped off.

Wigly 11-04-2020 08:08 AM

Thanks for the great images. The casting quality is really not that good ;)

I have an original set on my car (that were actually take offs from Lewis Hamilton's Cobra) and they hold very well. I've had them on for about 4 1/2 years now and drive the car 500 to 1000 miles per year. Yes they are a very rough cast but they certainly complete the correct look of my car.

Danr55 11-04-2020 01:17 PM

Those wheels, if I am not mistaken, are cast Magnesium. The modern wheels are cast Aluminum. The two materials are extremely different in metalurgical qualities and cast very differently. Aluminum makes a much finer casting than does Magesium.

Karl Bebout 11-04-2020 02:08 PM

An easy test to determine if the wheel is magnesium:
On an inconspicuous spot, put a drop of vinegar. It if bubbles up=magnesium. voila

my427cobra 11-04-2020 04:54 PM

Hi Dan and Karl. The original Sunburst wheels were designed by Peter Brock, and manufactured by Kelsey Hayes in cast aluminum.

Cheers

These were alloy as Greg states...

Wigly 11-07-2020 08:14 AM

Does anybody have a scan (pointcloud or CAD model) of the wheels or can create one?

my427cobra 11-07-2020 12:26 PM

Hi Wigly. There is a fellow on e-bay that 3d prints 1/8th scale model parts (webers, engines, wheels etc). At one time I recall he did the Sunburst wheels.

He may have a scan.

Cheers
Greg

Wigly 11-08-2020 01:07 AM

Hi Greg, oh ok, i will try to find him. But you do not know if the things are just modeled or based on real scans of the parts?

my427cobra 11-08-2020 08:34 AM

Sorry, don't know.

Cheers
Greg

Wigly 11-09-2020 09:18 AM

Hi Greg,

his name is Mike, really nice guy. But the wheels are not scanned. He builds all of the 3D models from scratch using visual references.

But if you would share a couple of dimensions with me, i would rebuild the wheel in CAD. Would you do that?

Gary Kumerow offers a reproduction of this wheel already (:

@66gtk
I not looking for wheels, i am looking for a scan of the wheel or measarements :)

@cycleguy55
Thank you for the contact information of Gary. I contacted him, hopefully he will anser

Maybe Greg will reply to my pm as soon as he has time.

my427cobra 11-13-2020 12:59 PM

Hi Wigly. Sorry for the slow response but life gets in the way.

Can you be more specific about the pics you want.

And I would hesitate to give any measurements that you might feed into a CAD program as I don't have the precision measuring equipment to make such.precision measurements.

But give me more info so i can see if i can help.

Cheers
Greg

Wigly 11-14-2020 12:35 PM

Hi Greg, no stress please.

I wrote you a pm with details i need for a rebuild.
If you don't get that please contact me, thank you.

Cheers,
Paul
