I am in the process of restoring a few classic metal planes, Stanley 5&6 Cs and a Sargent 414. I have done a considerable amount of restoration in the past: hand saws, braces, chisels...I have typically used Scotch-Brite pads, sandpaper, brass bristled brushes...and WD40 or Mineral Spirits. I have not felt comfortable using any sort of "power" equipment to strip rusty, discolored areas. I followed a link on this forum to a an article on more "advanced" methods, including using a sand blaster and sand blasting box, which got me rethinking the powered tool idea. I am considering trying the polishing/sanding pads on a Fein MultiMaster. I have thought about Evaporust but it appears to leave a dull unattractive surface. I am interested in hearing methods others use to speed this process.
