I'm trying to shoot some walnut at 45 degrees and it gets to the point where I can't take a shaving, the plane just skips along the piece. The iron seems plenty sharp and no issue shooting at the normal 90 degrees. As you can see there is a little gap at the top so the blade isn't contacting the whole piece. If I go hit it with the bandsaw and roughen up the end I can get it cut, but that defeats the purpose of doing fine adjustments once I've got it close to where I need it.

I just did a quick and dirty screw down a piece at 45 on my existing board. Anything I'm doing wrong here?
