David,
Sorry I did not have time to rely earlier. Thank you for your comments.
Reference the Form, I’ve been training myself (as I put it) to ‘See the Curve’. I think I’ve got close to (sometimes) mastering it.
However (and don’t I hate however’s!) I once posted a question about shaping the foot, but not much advice was forthcoming, it’s still something I’m not even close to being happy with. So I guess it’s a question of trial and practice (or avoid the need for a foot!).
But yes, I have left enough at the base to reverse mount and do something even if it’s just slim down and then undercut the concave form and refine the existing foot on the convex form. Even if they have moved a little more than expected.
I turned (and sold) a similar pot to the convex form before Christmas. But I’d wiped it with Black Nightmare (Rust & Vinegar), wire brushed and then Lime waxed it – very dramatic.
In doing that I discovered that the Heart Wood goes black and the Cambium layer is barely affected (well a very light dirty grey). So for the concave form I may well just wipe the heart wood to darken it and then allow the whiteness of the liming wax to make the cambium layer even whiter. I’ll have to be careful of the bark with the wire brush though. Still it’s all experimentation and learning curves.
I have not decided about the free Maple yet. Certainly a couple of my large coloured vases from the whole bole, but otherwise no idea.
