My health has picked back up, I am stoked! I get to start working on wheels and emblems again this week.

I think I've pretty much got the code issues resolved and need to run another prototype to finalize the notion that they are ready.

The bit wasn't fitting between the lip of the wheel and the petals, and was causing high spots.

Hi Jim, glad you are better and back to work on those cool parts.....looking forward to seeing them in person and those cool GT logos too.

Do you have any access to stereolithiography equipment or rapid prototyping 3D printers? If so, it might be a lot easier to manufacture small amounts of the wheels and be a lot cheaper too.

Jamie, thank you!

No, I don't. If I went that route, they wouldn't be billet aluminum. (IMG:style_emoticons/default/wink.gif)

Look, a pile of squared circles!

and a lurry picture of prototype number five next to number four. The differences are the holes in the webbing, the petals are separated from the lip and have more definition, and the petals have a larger corner radius along the outer edge that makes them more rounded and smooth.

I ran several different sets of code on number five to varying depths, fixing screw ups along the way.

New addition to my wheel making!


The 3 Jaw chuck bolts directly to my mill bed, or the rotary table. It holds the wheels in place MUCH more securely than the little vise I was using.

The rotary table also has a new addition; a stepper motor! Now it needs wired and the backlash taken out.

here is prototype number 7. (IMG:style_emoticons/default/smile.gif) I'm getting the back sides of the wheels figured out, and have the fronts pretty much wrapped up. The only thing missing is the hole for the bolt to hold it onto the car.

4th axis and tailstock bolted to the mill. I should be able to work on the code for the area the tire mounts in on the outside of the wheel now.

We moved last month, and my brother was kind enough to spend the day on one of his weekends off to help me relocate all of my machining equpment from my dad's shop to the garage that is basically on the other side of the wall from my living room. My CNC mill is less that 30 foot from my couch that I lounge on while healing and resting. (IMG:style_emoticons/default/smile.gif) Things are getting easier and looking up for me.

a close up of the tool path on my EMC/linux box.

the red lines are the ones that are done for this particular wheel.

This is the beginning of the pile of blanks that are ready for the above pictured tool path.

Wow! That is crazy cool. How cool would it be to have one big enough for a paper weight on your desk?

and here is another one that had a couple of glitches on the back side, and the 3 jaw chuck was .030" off center for the face. It's now a paperweight somewhere else w/out the tire on it.
