Thank you everyone, I did not expect that much feedback on this bow.
ajooter: No, don't chase a ring. You instead cut through the rings, but parallel to the fibers. That's the point. Ideally, you'll see nicely straight, parallel grain on the back. Look at the pic "beads", there you can see the cut-through ring on the back. You actually make a board bow from a stave.
I attached you a pic how the limb was cut from the log, hope it makes sense.
And yes, hazel is cool bow wood.
