Nicest piece of figure I got out of the sweet gum I scored last summer. This one was right in the crotch area of the tree and has some really nifty swirl and depth, I'd have expected the other side to have been similar but it wasn't
Sweet gum 11" x 2" with a wall pretty consistently 1/8 (might be off 1/64 here or there) - I left a small bump in the middle on the inside so I could carry the same thickness throughout and have a small recess in the bottom so it wouldn't rock - that also yielded some (unexpected but nice) change of shadows/light on the bottom. Weighs about 6.5 oz for the whole thing! When I was finish turning the center part it would pop and crackle as it came up to speed and pulled itself back round a little.
