I have turned a lot of apple. My customers really like it. I have had good
success turning green. When rough turned and then Anchorsealed, I have had
higher losses than with other woods due to the extreme warpage that is
perhaps twice as much as maple or birch.

Try to leave the heartwood in the center for interest (orienting like a
natural edge bowl) for interest. Beware if there are any existing cracks in
it, however.
