I'm building a pair of small cabinets, and I put together a solid Oak top. I planned on mating an edge piece on all four sides a bit of contrast, using some figured end grain Oak.
To make a little design "break", I decided to plane a little 1/16" relief cut in the top edges, and attach the Oak border. Just like a plywood top, except with solid wood.
I carefully set up my Veritas Jack Rabbet plane, and proceeded to plane with the grain. Yes the spur is down. Even so, I was getting a little "fuzz"; once I began to plane across the grain, the tear-out reared it's head something fierce.
I could certainly (and much faster) set up the table saw, but I'm curious about why a plane with the nicker down isn't slicing the grain.
