Mark,
forgive me, firstly, for venturing into the turning zone.
This is a beautiful piece, but I am really intrigued as to why you would turn the oak?
I don't have a good idea of the sizes involved, but that oak piece looks like it would be relatively simple to cut out on a bandsaw then carve and sand to shape. Why involve a lathe at all?

HI Mike
Thank you for the comment. #
You are quite right this piece could be cut out using a band saw. However this would involve firstly drawing a flowing line which replicated the final form.
Then a clean flowing line would have to be formed with the band saw and any slight movement away from the line would require blending before the edges were rounded over by either a rotary or reciprocal carver.
By using the lathe I do not need do draw any curves ( which I would have to alter depending upon size. This only takes a small amount of time but time is money as they say.
By turning the outside profile the flowing curve is easy to achieve ( and quickly) with a skew, which also leave a fine finish needing much less finishing than a band saw cut, if indeed any finishing at all on the cut part.
Also by turning, the edges are rounded over to start with and get tighter in towards the base. Again I do not have to worry about getting the flow of the convex outside curve of the side. With the band saw again this would need to be blended in and leaves room for error. The band saw method is also slow and would involve too many processes after the cut to shape and blend the form with any accuracy and would not make this a commercially viable item for me to sell.
With this sort of simple form any slight mismatch would show easily and would ruin the look of the piece.
Basically this is a rugby ball shape with cut outs. Would you make a rugby ball on a band saw. ?
So after my waffle ( which people will tell you I am master at)
:lol: :lol:
The reasons for using the lather are.
1/ Speed
2/ Accuracy.
3/ Fine finish from the skew.
3/ I get a 2 axis curve both up and sideways so less processes.
4/ Because I like turning. :lol:
I hope this answers you question.
