The polishing was done on the lathe, with a rag dipped in polishing compound. 6061 T6 takes a polish very quickly, it is a hard type of aluminum. The finish machine process is just taking very light cuts being real careful to move the cutting tool as slowly and at a constant speed as I can. This is a pic taken several years ago of the Logan 10" lathe that I have.
