I would say yes.Look likes the holes for the lug nuts are missing.They should be included also that will determine how the the design can progress.Or if the wheel is attach in the center spindle of axle..Disregard lug nut hole pattern thought ???

Thank you wd,

I don´t think that the holes are important.

I´ve tried to make it today in the evening, but without success.

I had troubles to make all the rounded edges.

Can you post one or two additional views of the object?

Halibrand pattern used on GT40s and Cobras, very simple.  Great pic here: http://www.seriouswheels.com/pics-2008/r-z-0-9/2008-Shelby-85th-Commemorative-GT40-Halibrand-Wheels-1280x960.jpg

Looks fairly straightforward -- provided Genie cooperates with the filleting operations.

The only place that blending needs a bit of planning should be where these blends feather into each other.  Everything else is pretty straightforward.

How come they have to use wire to hold it all together? :-)

This one isn't even close to accurate, but I think it shows that TC is up to the task.

Great job on that Brad.

Looks like the original jpeg is from SolidWorks or Inventor. I do also think that the fillet genie might be working a little hard. Could you post a jpeg of the rear side?

My gosh, that's nice, Henry.  After I pointed to that picture, I realised that there are two styles of that wheel, one fitted to Ford GT40s, the other to Shelby Cobras.  Although Rudl's is identified as GT40, it's a Cobra style, the difference being the webs to the hub centre.  You've done the GT40 one, which is more involved than the Cobra's, the similarity is superficial.  And when I Google-image-searched Halibrands, the image that Rudl posted came up as somebody's Solidworks effort.  Yours is gorgeous.  Kudos.

Its beautiful thing all needs is some rubber revolve around and set four and they're ready for the the show case at Hailbrand.I must say those wheels don't come cheap.

Someday I might be able to do that, as quick as you have; some day;)

 I'll not make a complete rim, thank you.

Well, I lied.  I couldn't help myself and I had to give it a try.  I used two revolves, two spins, two mirror copies, and some shelling and lots of add and subtraction.  The blend radii went from 0.03125" to 0.500".  The most tedious part was in the positioning of the various components and then the radial fit copy.  It's not for a GT40 but a '94 Ford Escort.  I found that I couldn't do an exact duplicate.  Rendering took up much memory and when I tried Quality I got a notice "Out of Memory".  I need to learn about lighting, shadows, etc.

Turned out great. You used a different approach from mine, and yours makes a lot of sense.

If you're not ready to quit yet, here's a tip that might enable you to render the whole thing without running out of memory: Slice your wheel into six identical sectors; delete five of them; format the survivor as a Block; radial-copy it. Then try rendering.

I copied the rim to a new file and sliced it but when I tried to make a block all I got was a big red X but it rendered faster anyway.  I never make blocks, only groups.  I got the file down to 1.33 MB from 2.40 MB with the copy.  Glad you like it.

***EDIT***   How did I get six lug nut holes?

I assume there was a hole in the segment that you made five additional copies of ;-)

If there wasn't a hole in the segment then there wouldn't be any holes and you're forgiven.  ;-]

Try Format/Explode once.  It seems to work a little faster.

If you make the edges square you can do a second operation and fillet them into round edges. If you only make one segment of the rim you can use a radial copy to create the remainder of the rim.

Gammaman,

I started off with a triangle, then filleted the corners, then shelled, then blend edges, and then scaled to size and fit. A large and small box were added together, blended and mirror copied.  After I got all the components ready I then did a radial fit copy to get the six copies.  A lot of work in getting the right positions done the way I wanted and there was much re-do.  One thing I did was to make a polyline in the middle of a shelled triangle with a lot of Properties/3D so I could subtract it to make openings.  It's all part of my New Year's Resolution to try to learn more of TurboCad and picking things out of the Forum is better than reading a book.

The GT40 doesn't use traditional lug nuts but has a threaded wheel spindle and a central spinner that acts as a single lug nut. It makes changing rims/tires in racing very quick. Some of the later pictures show the the spinner attached.

I kind a figure that out by now with all the later images loaded. Keep in mind that was posted early in the thread when the original discussion didn't have enough info to go on. I also mention that if "Or if the wheel is attach in the center spindle of axle..Disregard lug nut hole pattern thought" ;D
