Home depot plane. Haven't done it before so I wanted to start with this plane before the LN. Very not flat, but it wasn't too hard to fix with 60-grit and granite surface. My question is about the last millimeter around the mouth. Looks like I would have to grind the whole bottom for a while to get the mouth edge both before the blade and behind the blade.
How important is it that the edges of the mouth be perfectly in line with the sole?
