It feels like I've spent the whole week trying to fix a mistake I made when sharpening this plane iron. I got the angle wrong, and trying to grind it out is taking an age :(
@quixoticgeek Can you rough in the correct angle using sanding paper on a flat surface?
@quixoticgeek weird!
beyond that I'd be tempted to doubt the flatness of either the plate or the surface below the sand paper.
At least it looks like you're nearly there.
