This is my latest shooting board. The first image is in normal mode, the runway is a part of a Tesco cutting board, not the small vertical piece (woodbloke idea) that the sole of the plane rests against.
the second image is with the mitre attachment, note the clamp to restrict any movement on the back stroke. You will see in the third image that the mitre attachment engages with a 6mm pin on the left of the main board, you can just see the hole. To the right of the mitre board you can see a fine adjustment screw, this allows you to set the mitre board to exactly 45 degrees.
