Nope, Engine Turning is exactly what he described the process as being.
I haven't heard the terminoligy of "engine finish" other than as a
diffeerent name for the process by those that want to make a new name for
the process.
Engine turning is the swirlling finish that overlaps as you go across the
piece of work. The only problem with doing the finish is getting the steps
exactly the same distance from each other. Being off by even a little bit
makes the finish look ratty and uneven.
I'll note that Cratex makes a lot of toolbits for doing this finish in a
large number of sizes.
