I can tell when I've got it right as the tool just glides over the surface of the wood and leaves virtually no tool marks...well no more than HF tools will get you. It appears as though I'm shearing here rather than chipping. But that probably has something to do with freshly cut up christmas tree I'm using here. A drier wood may produce more "chips" than thin layers...just guessing though.
