Hi Mark, I haven’t tried turning green myself . . . Yet . . . But there is an interesting book on working with green wood titled
Green woodworking : handcrafting wood from log to finished product / by Drew Langsner – ISBN: 0878576894
There is a section on “boring” which may give you some useful information. I came across this at my local library, so you might want to take a look at yours to see if they have a copy.
One of the local turners near me does green bowls, which turn out as ovals once they are dried after being turned. Interesting items that seem to sell well.

I turn quite a bit of green wood. Lately, most of it has been ash since the city is cutting them down by the thousands owing to the borer. I have done maple, birch, cherry and walnut green, too.

If you turn bowls relatively thin – 1/8 to 1/4” – to the final shape, they will warp nicely, usually, and not crack. Then a final sanding and finish. You can get some nice “potato chip” shapes.

You can also turn green as a twice turned bowl. You turn the shape green, but leave the wall thickness about 10% of the diameter. So, a 10” bowl has 1” walls. Then, you bag it or wrap it in paper and leave it for months. The plan is that it dries slowly, so it warps a bit, but does not crack. When it’s stopped losing weight, you remount it on the lathe and turn it to final shape and wall thickness.

Green wood is best you can get for bowl or hollow turning, bazaar shapes not always predictable. Depending upon how you cut a blank out of a log and orientate growth rings will different effects. Species & density also have affect on wood movement.

Although we all know wood shrinks when as it dries looking at this picture shows different shapes you can expect when cutting boards from a log.

For bowls & hollow forms & grain orientation click on images at this link.

Rough turning a green bowl or hollow form blank to a uniform thickness and letting wood go oval pretty standard and allow wood to dry enough for finial turning & finishing.

Turning green blanks thin not always a going to be successful, but don’t let that stop you from trying!
