I bought a rusty 6x6 fine pole magnetic chuck on eBay last year, and today we're going to clean it up and grind it in. The chuck is a Suburban Tool MC-66-FP-S1 and the seller claims it was new, but "has some rust problems". I'll say it has rust problems. Let's see how bad the damage is and if we can fix it.
