Turn the outside of the bowl to shape. Renew the edge of your bowl gouge. Make a final cut moving more from swaying from your feet then moving your hands. Make one cut for the entire bowl. If not satisfied, make another final cut. If there is a pull out apply heavy oil or wax. If surface is satisfactory, sand. Start with as fine a grit as your surface will allow. End up with 400 or even 600 grit and white nylon pad.

If the surface shows undulations after the gouge, scraping may be necessary. The best way is to use a one inch scraper held by hand instead of directly resting on the tool rest so that the blade cuts at 45 degrees and is dragged back the direction of the cut. I have not yet mastered this technique. Alternately, use a wider scraper on the tool rest so that the edge is at or slightly below the turning axis. The rest should be as close as possible to the work. Again, move from the feet so the whole body is leaning with the cut. Oil if necessary for pullout.

Hollow out the bowl. Usually you can get a smooth final cut if you keep the bevel of you gouge resting on the bowl and take a thin bowl. A curved rest helps. The bottom of the bowl can be smoothed with a scraper. I have trouble with a scraper on the inside sides of the bowl, particularly near the edge. Undulations can be sanded with a power flexible edged disk.

I use different finishes depending on the purpose of the bowl and the type of wood.
