Mark,
Thank you, I noticed our posts crossed as well.
David,
Not FOG wood, a friendly tree surgeon who keeps his eye out for me.
I want to make another one but balance the spalting better. It ends at the heart wood, growth wood point with the wide line you see in the third image. So I'm looking to cut and mount the next piece more carefully so it runs around the form and not rise up through the rim.
Well, that's the plan!
