If you have a profiler, ensure that you keep the blade sharpened. It will make the scraping much easier.  I sharpen the blade myself using a carborundum stone, about 30 strokes against the beveled edge of the blade, direction is edge forward, finishing with one stroke on the opposite side and the opposite direction.  Don't overdo the sharpening or you will wreck your blanks.  You can test the sharpness of the blade by running it gently across your fingernail - it should stop against the nail - all the way along the edge of the blade.
