I need to put a smooth finish on the inside of some aluminum tube. 1"
ID smallest - 2" ID biggest. Same application different sizes. If it
was steel or cast iron I would just run a brake hone or cylinder hone
down it, but I think the stones would just pack up with aluminum if I
tried that with this. It doesn't need to be precise, just smooth. I
want to round off the weld seam (not to bad to begin with) and make it
fairly shiny inside. Flap wheels? Buffing wheel with a "course"
substitute for rouge? Other?
