It's kind of hard to tell with the grainy picture, but it appears that you have a fillet all around your spokes and where the spokes contact the hub/rim. These will be nasty to machine, so you might consider increasing the radii of the ones going in the same direction as the axis of rotation of the wheel (the ones that can be cut by a mill bit when the wheel is laying flat), and getting rid of the other ones completely (if this is confusing, just tell me).

Also, how are you CADing the spokes? If you try a circular pattern, you shouldn't end up with spokes that aren't "in sync," as you put it.

Good start, though.
