Over the past few months, I’ve been working on this plate. It’s made from sweet gum that a friend sent me. I started with a piece that was roughly 12 inches square (300mm) by 3 inches thick (75mm). I finished with a plate that is just under 12 inches in diameter, and about an inch thick, and which isn’t quite flat. Sweet gum moves a lot as it dries, and I didn’t account for this movement in my initial turning.
