I turned a straight sided end grain box this afternoon. After I drilled the cavity out with a 1.5 inch forstner bit, turned the tool rest across the face of the box and used a 1/2 inch skew chisel, laying on it's side. It plunged the tip of the skew into the wood and took a 3/16 inch cut out of the wall of the box. Once I got to full depth, I did another one taking just a little less. The interior wall of the box was fairly smooth. There were some wood curls at the base and I cleaned those up with a straight square end scraper. The interior sides required very little sanding. I was turning yellow poplar, a very soft wood anyway. I could not believe how fast I could cut out the interior. I thought a skew for interior turning is supposed to be a major no-no. Was I just lucky or is this something that is known?
