Project #4, Big Fake Diamonds, d.fisher

[jp2code]

That's amazing and impressive.

I've just got to blow one up....

As a faceter and gem cutter I can say "close" but not quite. Those "sunken" facets would be impossible to cut but still it is pretty impressive art.

Exactly! You are only the third to see the major flaw, most people read this as a diamond but don't know how one is cut to begin with. It's a pretty major flaw, and I knew it soon after, but then the project took on a life of its own. And lucky for me, Tolkowsky lists a section of incorrect diamond geometries in his manual, so I am chalking this up to a diamond that falls in that section. ha ha, I may come back again and try another one, but there's too many other projects on my list at the moment. Thanks for the link, I haven't checked this out until now. It's a great resource for the future.
Thanks again,

Thanks again jp, I haven't found where to post a large picture like that, is there a quick answer on the "how to?"

[jp2code]

I don't know.

After you post the attachment, someone can click it to open it in another window (what I do), then copy the link and insert it between [IMG] tags, like If that were a real link to a real picture, the URL would be replaced with a picture.

Once you figure out how to do one, the rest are super easy.

Also, images uploaded on here are only visible to other members. So, if you gave the link to your mother or brother, they would not see the images. If you want images visible to all, upload your images to someplace like www.photobucket.com or www.imgur.com (both are free). Then, you'd place your IMG tags with the links to your photos, like this one:

Ok thanks again Jp, I'll try this in the future. Is that your motorcycle in the truck?

[jp2code]

Yes it is.

In your 68 Chevy thread, I think that other guy left thinking my green pic of that Chevy truck was your end result. Ooops!

I've got an album here: http://jp2code.imgur.com/all/

Very impressive work, d. fisher! I like the "wood grain" look of the pine one.

I gotta say though, a version made out of welded, ground, and polished stainless steel sheetmetal would be possibly even cooler.

On a side note, does anyone know how real diamonds are "cut" or polished? I'm just curious. Given they are one of the hardest substances known to man, I can't think of any known abraisives that could get the job done without wearing out at least as fast as the diamond being polished. Are they fractured in a controlled manner somehow?

no worries. hopefully some paint this summer will finish that 68 chevy thread out nicely! i checked out your album. you have some great looking machines in there. did you do the paint on your xr1200? it's a great looking motorcycle, and a solid restore on the nissan truck. it looks super clean from how you got it.

thanks for the props jakeru. if you want to see some metal diamonds, do an image search of Jeff Koons. He has an army of workers to do exactly what you said. He paints his work afterward, but the stainless is first brought to mirror quality. they sometimes take a few years to complete depending on the sizes.

and regarding how the real diamonds are made, you are correct in your thinking. larger raw diamonds can first be fractured to create higher quality smaller diamonds. diamond sawblades and lasers also do rough cutting. in terms of faceting and polishing, diamonds are used to polish other diamonds. in the case of the diamonds doing the work, they are usually reserved as industrial quality and very small, sometimes grain like. if you check post #20 in this thread, Thurmond would be the man to ask. I only sort of know the process from being a jeweler, and don't actually do the real deal of cutting/faceting.

Hey, thanks! There is a long story on how the "XR" came to be painted that way. It is painted how I envisioned it, but I had no idea how to get that done. It was at a local paint & body shop scheduled to be painted blue because that was the only solid color I found that I liked. While waiting for paint, a carbon fiber scoop came in that was on back order, and I wanted to have the Harley-Davidson dealership paint it black to match the original. They gave me the name of this guy named Ben Beebe that did all of their painting. I took it to him, telling him what I *really* wanted. He took off with the idea, and said he really wanted a shot at doing that. He did all that for $800. I was amazed!

The Nissan Hardbody was my dads. He used it for 15 years in the oil field as a service truck, then retired it for a few years as a ranch vehicle for mending fence and feeding cattle. In 2001, a tornado hit my parents house, and a tree went through the truck's windshield. By the time he was finally to the point that he needed something new, the local dealerships would not accept it as trade - it was that bad. It is the rare 3/4-ton Heavy Duty truck, and I hated to see it go. So, I sold my Scion xB and used all of the sale of that vehicle to fix and repair the old Nissan. It still needs a few things, but it looks pretty close.
