Gentlemen,I'm not sure what the proper term is, but I'd appreciate thoughts on how to getthose "turning/swirl" marks on a bare aluminum cowling.Is it a very fine stainless wire brush in a die grinder or one of those nylon abrasivebrushes?? With a piece of metal the size of the cowling parts, using a drill press is out,so I assume it'll have to be handheld, maybe with some sort of jig.Thoughts??Douwedouweblumberg(at)earthlink.net________________________________________________________________________________

HI Douwe,It is called "Engine Turning". I did my instrument panels using an old intakevalve with a circular pad of Scotchbrite superglued to it, mounted in my drillpress. It only takes a second of pressure to put the swirls into aluminum.Jack Phillips>
