Default Re: What is the best way sand aluminum and to be able to do it fast?

I bought an air polisher from Chicago Pneumatics. It is absolutely my favorite polishing tool. It turns maximum about 3000 RPM. They make a sander that turns 15,000 and looks just like this but that's too much.
I use it with 3 inch, and one inch, Velcro disks, usually with a little WD 40 or a little water. I made a one inch diameter cookie cutter from a band saw blade to cut the centers out of the 3 inch disks after I have worn them out. The centers rarely get worn at all. I have soft pads about 1/4 inch thick, made by 3M, that fit between the disk pad and the sandpaper if I want a softer sanding surface. I can sand up to 1200 grit with this thing.
It saves an enormous amount of work. Of course it doesn't get down into small crevices and such.
