I was given a free craftsman table saw with a cast iron top and extensions. It's never been used and I got it in the original never opened box.
This saw was built in 1986 and has since been sitting in someone's garage. The box was penetrated by moisture and the table top and the extensions are completely rusted. It seems that the top was covered by a protective sheet of paper and it's now completely grafted onto the table top surface.
How should I go about rescuing this saw? (The rest of the saw is in pristine condition.)
