This silver maple bowl is the largest bowl (13 inches) that I have turned. It is about 4 inches deep. The rim is textured following a method of using an engraver I learned from Molly Winton. The rim was then painted with black gesso and finshed with General Finishes WTF. The finish was a bit too shiny for me so I knocked it down with some steel wool. Turning something this big forced me to make a new donut chuck in order to finish the bottom.
I should have mentioned that this wood was courtesy of Creeker Doug Swanson who gave it to me over 2 years ago.
