I'm learning to use the (LV skew) rabbet plane. My rabbet bottoms( faces?) look good, but verticals (perpendicular to the blade cutting surface) are kind of ragged, particularly if cutting crossgrain. I've been trying to fiddle with the adjustment between the scoring wheel and blade, but still need to take a pass or two with a shoulder plane to clean up the verticals. Is this to be expected, or should I be able to get two smooth faces with just a rabbet plane? What am I doing wrong?
