I have a question on turning Hollow Forms. When turning HF's out of green wood how far do you rough them down before you put them up to dry? Do you treat them kinda like bowls and leave the walls 10% of the thickness? Do you hollow the inside out to say 3/4" thick walls then DNA it and then let it dry? The ones I have done thus far has been dry wood. The one I did out of ash from green to finish about the only thing that didn't crack and split was the walnut collar I put on it because it was kiln dried wood. Any advice would be appreciate. Thanks.
