and I aint figured it out yet. I'm using a LV Skew Rabbet plane to put a 1/4" deep, 3/8" wide rabbet on the 3/4' edge of some Borg Poplar. It's cutting great except I'm not ending up with a right angle. The floor of the rabbet is tipping down a good 10 degrees or so. After the first one, I was pretty sure I needed to concentrate on keeping the fence tight to the side of the piece but I just got done with the 2nd attempt and it's not a huge improvement. Blade is parallel to the sole. What am I doing wrong?
