I just finished cleaning up a Stanley #82 scrapper. I used Evaporust on this project, and I have to say it worked just as well at the electrolysis method and was a whole lot easier. My question is what is the correct way to sharpen the blade? It does have a bevel already. Should it be truly sharp or just ground square? Should the blade have a burr? Any suggestions would be appreciated.

The thing is, the scraper planes have a much thicker iron and you use them more aggressively than you would a card scraper. You can put a bit of a burr on it but the scraper planes generally are just sharpened to an edge. A higher angle than you would use on a plane iron. I would go with about 35-40 degrees.

The #80 is a bit nicer for that. As you tighten the screw, it bows the blade like you do with a hand scraper.

You mentioned evaporust. Is there any pitting on the back of the scraper blade, if so replace the blade? You will never get a scraper sharp if a pit runs through the edge. I file my blades a 45 degree angle, polish both the bevel and back with my finest stone, then use a carbide burnisher to form a small hook (you can feel it but not see it) on the blade. This hook does all the cutting.

Look at this video from William Ng. Good info about cab scrapers.
