My parents gave me a new set of cast iron pans shortly after I started living on my own. I noticed they didn't have smooth bottoms like theirs did, so I asked my dad if he could help me smooth it out. He put a grinder attachment on the drill and went to work. I still remember it as one of the nicest things he did for me. And the pans still work great, 40 years later.
