Well, I can be a lazy bastard sometimes. My WWII blade has been burning a lot lately. I knew it was a bit gummed up, but I just didn't want to mess with it. Yesterday, I got some nasty burn marks on the edges of some nice mahogany for a haberdasher I'm building. I finally got the CMT orange stuff out along with a brass brush. You wouldn't believe the crud on that blade. It's shiny new looking now. First pass through that mahogany, it slid like s*it through a goose. And no burn marks. I gotta be less lazy in the future....
Next task: Sharpen those jointer blades that are leaving streak marks on the wood. Might not have to sand so much......
