Depends
Mike Schwing from Maryland
>How I rough with it depends on a few factors. If its truing up a surface I won't expose much cutting edge and use mostly the tip, with the flute pointing in the direction I wish to go. If I'm hogging off a lot of waste, I'll use the side grind and rotate the flute up to about 10 o'clock. If the wood is willing to cooperate, you can hog off unbelievable amounts of material with each pass. Depends for me on the grain direction, wood species, and if its wet or dry. You have to have quite a good grip on the tool to do this as it will cause quite a bit of torsion as it tries to push that flute down. A little too much bite and you'll know it quick. As I get nearer a finishing cut I'll move back towards using more of the tip, and for final smoothing/leveling of a round surface - not the final shearing cuts, I'll use the side grind nearly horizontally.
I really didn't understand at all how to use this marvelous tool until I bought his signature gouge video. No one could have adequetely explained it to me with words. The thing that amazes me every time is the near complete lack of tearout.
