I did a little stainless gauge panel in my 34 jalopy. Not quite as nice as Petes photo above, but good enough for me. I used a wooden dowel, cut a circle in some fine sand paper with a hole punch, and glued it on. Lay out your pattern with square lines and a fine felt tip pen. I used a mill, but a common drill press would work if you clamp a guide on the table to keep you square. Spray WD 40 as you go to keep the sandpaper from plugging up. Practice on a junk piece to know how long to burn it in, and how much pressure to apply. My piece should have been burned in a bit more...but Im ok with it. Looks better in person than the photo. As said, there are lots of videos on it.
My photo shows the experiment of 2 different size wire brushes. I think I went with the sand paper in the end.
