just a suggestion and not to discourage you from exporing that wood,, but maybe get a white oak or hickory thats pretty clean and straight to start with,, and experiement with the olive later when they cure,,, if the wood is not so good for bows, you might blame your experience level and get discouraged,,,start with a wood thats pretty consistant with success,, I would even suggest a board,, you can always crown it a bit and make it look like a stave bow,, just dont make it complicated for yourself at first,,
