@David Wyke , I LOVE the shape of your rim, inside and out. I wonder why... Although I don't turn many bowls I've used similar shapes a time or two. One reason I do some rims like this is I think undercut rim and the outer flare make the piece easier to pick up and hold securely.
I made this one about three years ago just to make sure I could still turn a bowl. A friend wanted to turn his first bowl and it had been years since I turned one so I did three in a row with various shapes, both to show him some options but more importantly, so I'd be able to explain the steps to him without saying something really stupid. (Well, that's never stopped me from saying dumb things before but it sometimes helps.
I used a sloped flat on the top of the rim for this one. I liked the walnut. Gave it to a guy in the club.

This was the second turning of a dry roughed out blank. I always say if either coring or shaping a green blank for twice turning make the wall plenty thick to give lots of design options after the wood shrinks and warps while drying.
