All the turning is in real time, so you see how I turn and sand a flat surface. Then when I’m not satisfied with how the tray feels you see it again as I reduce the thickness of the base. Corrupted files meant I lost most of the sanding and finishing, but you do see sanding with oil after I've thinned the base a second time. You’ll hear the difference. The sushi tray is 240x45mm. The wall thickness below the bead is 7mm.
