what I do (or did) I have 21 feet of countertop laminate in my kitchen is put the top down with about 3/8" overhang on the front edge. I adjust my router with the straight ball bearing bit down so that about the middle of the cutter cuts the laminate. the bearing rides on the osb for the top. the edge I cut accurately so when that's glued up it's perfectly level with the top. after the contact cement has cured - 24 hrs give or take, I attack the edge with the ball bearing 45 degree cutter. I adjust it so that the bearing is about 1/2" below the countertop and just the very beginning of the bevel cutter touches the corner. this way I round off the sharp edge and don't take too much material off. I follow up with a folded sheet of 320 grit aluminum oxide paper.
