I love the look of this "engine turning" swirling pattern on vintage machinery. I bought a kit from Eastwood.com. I was thinking of doing the panel this way. After some more consideration, I decided to start small and try it on something first. This is the subpanel for the throttle and mixture controls. This small piece was a LOT of work to do. I laid down a bunch of grid lines on some plywood, then used that to lay out the swirling pattern on the aluminum (which was highly polished first).
