Yes, I used a DA orbital sander (pneumatic) to remove all the rough surface from the inside base of a Lodge pan. This, of course, removed the seasoned finish. The new surface was harder to season (took several months to get a uniform surface with no spots that would wear off under scraping/abrasion), but it's very capable now. I prefer it to the rough stock surface.

Wear a respirator unless you want to taste rust every time you breathe for several days.
