One Co-Hog Porsche G935 is being made for each of my sons. The fourth one I’ll keep for the collection.
Shea's automotive passion has endured from very early on. Many of his exploits have become family lore and others remain secret. Why we needed to change out the oddly bent differential in his black convertible Mustang GT in our driveway is in the latter category.
That Mustang was the love of his life (his wife excepted, of course) for many years and he had a set of chrome Ford racing wheels for special occasions, so his Co-Hog G935 is black with chrome Porsche five-spokes to match.
The body is in the final stages of sanding before final color, but the wheels and tires are ready to mount. It took three tries with different paint brands to get the chrome right, but it was worth it.
Revell's Chrom (no 'e') was the winner. The rattle can spray was decanted and airbrushed to get into all the nooks and crannies.
Since they were going to be painted, the tires and wheel rims were turned from acrylic rod.
No CNC or carbide tools were used. Just stubborn patience.
Everything, including the five-spoke centers, got several coats of gloss black to start with. The tires were later given a flat finish.
During finishing with the second brand of chrome paint the spokes were sprayed separately from the rims. It turned out to be better to paint them as a unit.
The winner of the chrome challenge was a Revell rattle can spray paint, decanted and airbrushed to get into all the nooks and crannies.
The separate, bigger wheel is the test piece used for each step of the process.
The spoked centers were carefully cleaned up FDM 3D pieces printed using a wood and PLA blend.
The smaller nut, spokes and aluminum wheel next to the green dot were used on the last of the 1980 Co-Hog Porsche Restoration group.
The ones to the left of the blue dot are for this Co-Hog G935. Each set of spokes, rims, nuts, and tires were individually matched. This acrylic rim is marked #1. At a small scale, tiny size differences result in a big change in appearance.
That attention to size and matching parts was especially true for the wheel hubs and nuts. The hubs are aluminum turnings, and the nuts are combined from two brass turnings. For comparison, the pencil lead is 0.020" (0.5 mm) in diameter.
Again, no CNC or carbide was used. Numerous extra parts were made though, just to be sure.
All four wheel nuts are painted and ready to assemble.
I can't resist a final beauty shot of the wheels and tires set before final nut assembly. They turned out well.
Now it's time to finish painting, graphics, clear coating, and polishing to finish it off.
