I just did my first one. like somebody up here said, it's a simple process, but it's far from easy. Sort of like golf. Easy concept, but hitting that darn little white ball straight and long is not an easy thing to do.
I used a grinding wheel after two burn out and it takes most of an afternoon. And I'd suggest a flap disc rather than the wire wheel. Just be careful you keep it moving so you don't burn it too deep.
When I die, my goal is to have a visible smoke ring when the coroner cuts me open for the autopsy.
