Image 1 shows my two Landing Light Mounting Frames marked up and ready to have the centers removed. Image 2 shows one of the Mounting Frames with the center cut out (using the pneumatic nibbler) and the edges cleaned up and clamped together with a set of 0.050 frames so they can be matched drilled together. Image 3 shows me match drilling the frames along the top edge.
