I work for a company that has a CAD/CAM laser cutter, an endless supply of 304 stainless and a programmer that's a certified motor-head. I needed an instrument panel for my Willys project so I fired off some dimensions to the programmer and a few days later the finished panel showed up at my office. I polished the panel beginning with 180 grit paper and ending with 2000. At this point I felt the panel was a bit mundane and thought engine turning would be cool.
I read everything I could find on the internet and went for it. I got some scrap stainless and practiced for several weeks. The real trick is to be consistent with time and pressure applied to create each turn. I made a fixture to give me straight lines and overlapped each turn 1/4" on all four axis using 1/2" wood dowel and 100 grit grinding compound. There are real artist out there doing beautiful work, but I'm happy with my attempt. The great thing is when someone ask me where I got the panel, I can say I made it! Attached are thumbs of the process and finished product. If you get the urge, go for engine turning.
