Been working at 6" jointer blades for a couple evenings. I get a great sharp edge but after having problems mounting in the jointer, I see there is a bow to the edge. The middle of the blade is at least 1 mm higher than either end. I retrued the stone and did it again and got the same result.
Is it my method, my jig or what? I can't figure out what would cause such a bow.
HELP! I need straight blades. And soon!
